Progress in Agronomic Crops Lodging Resistance and Prevention: A Review

ABSTRACTCrop lodging is recognised as one of the yield‐limiting factors in agricultural production. Therefore, better understanding to improve lodging resistance and to prevent lodging‐induced losses in agronomic crops is necessary. Besides yield losses, lodging severely affects the crop harvesting process and increases the production cost. However, achieving the objective of higher crop yields and yield quality without increasing lodging risk is quite challenging. To this end, it is essential to interpret the underlying mechanism of plant stem buckling and failure of root anchorage and optimise the fundamental trade‐off between lodging resistance and yield performance in agronomic crops. In the present review, we made an effort to discuss recent and innovative research insights that guarantee greater lodging resistance along with advanced lodging prevention strategies while sustaining higher crop yield and yield quality.

The carbon emission reduction benefits of the transformation of the intensive use of cultivated land in China

The transformation of the intensive use of cultivated land has an important impact on agricultural carbon emissions (ACE). However, the existing research on the impact mechanisms of the transformation of intensive use of cultivated land on carbon emissions is not clear. In view of this, this study constructs the impact mechanism of the transformation of intensive use of cultivated land on carbon emissions from the perspective of production factors substitution based on the theory of induced technological change and the theory of marginal returns. Using the Cobb-Douglas production function, this study identifies the transformation patterns of intensive use of cultivated land in China from 1980 to 2021. Furthermore, this study simulates the carbon emission reduction benefits brought about by the transformation of the intensive use of cultivated land by considering the cost of agricultural production. The results show that, first, from 1980 to 2021, the price of agricultural labor increased by 224.10%, while the price of other agricultural production factors significantly decreased. China’s intensive use of cultivated land methods has undergone four stages: agricultural labor–intensive (ALI), yield–enhancing factor–intensive (YEFI), labor–saving factor–intensive (LSFI), and innovation factor–intensive (IFI). In 2021, most of China’s provinces were in the YEFI or ALI stages. Second, between 1993 and 2021, the transformation of China’s intensive use of cultivated land brought about an 87.48% increase in carbon emissions, while the spatial clustering effect of carbon emissions weakened. Furthermore, the results show that, the transition of the use of cultivated land from ALI to YEFI and YEFI to LSFI will reduce carbon emissions by 7.89%, and input factors costs will increase by 23.85%. If all regions, except for those in the IFI stage, transition to the LSFI model, it will result in a 17.56% reduction in carbon emissions, with a corresponding increase of 33.40% of the input factors input costs. This research enriches the theoretical foundation of literature about the transformation of the intensive use of cultivated land. It also expands the research perspective on agricultural carbon emissions. This research also helps provide references for the direction of the transformation of the intensive use of cultivated land in China and the achievement of the dual carbon goals.

A Novel Interpolation Method for Soil Parameters Combining RBF Neural Network and IDW in the Pearl River Delta

Soil fertility is a critical factor in agricultural production, directly impacting crop growth, yield, and quality. To achieve precise agricultural management, accurate spatial interpolation of soil parameters is essential. This study developed a new interpolation prediction framework that combines Radial Basis Function (RBF) neural networks with Inverse Distance Weighting (IDW), termed the IDW-RBFNN. This framework initially uses the IDW method to apply preliminary weights based on distance to the data points, which are then used as input for the RBF neural network to form a training dataset. Subsequently, the RBF neural network further trains on these data to refine the interpolation results, achieving more precise spatial data interpolation. We compared the interpolation prediction accuracy of the IDW-RBFNN framework with ordinary Kriging (OK) and RBF methods under three different parameter settings. Ultimately, the IDW-RBFNN demonstrated lower error rates in terms of RMSE and MRE compared to direct RBF interpolation methods when adjusting settings based on different power values, even with a fixed number of data samples. As the sample size decreases, the interpolation accuracy of OK and RBF methods is significantly affected, while the error of IDW-RBFNN remains relatively low. Considering both interpolation accuracy and resource limitations, we recommend using the IDW-RBFNN method (p = 2) with at least 60 samples as the minimum sampling density to ensure high interpolation accuracy under resource constraints. Our method overcomes limitations of existing approaches that use fixed steady-state distance decay parameters, providing an effective tool for soil fertility monitoring in delta regions.

IMPORTANCE OF PUBLIC FUNDS AND DEBT CAPITAL IN FINANCING INVESTMENTS IN POLISH AGRICULTURE IN 2004-2022

The article assesses the importance of public funds and debt capital in financing investment outlays in agriculture in Poland in 2004-2022. The analysis used statistical data on inputs of production factors in agriculture, in particular investment outlays, as well as budget expenditure on agriculture, farmers’ credit indebtedness and leasing of agricultural machinery. The analysis included both nominal values and values adjusted for the CPI index. It has been shown that capital expenditure in agriculture increased in the years 2004-2022, including nominal and real investment expenditure. During the period under study, the importance of public funds, from the national budget and European funds, in financing agriculture increased. This also applied to investments in agricultural farms. In 2004-2019, a dynamic increase in investment outlays financed in the form of bank loans and leasing could also be observed. A positive correlation was demonstrated between investment expenditure in agriculture and the level of budget expenditure on agriculture and farmers’ credit indebtedness. In the last years of the period under review, i.e. 2020-2022, a decrease in the share of external capitals in the form of long-term bank loans and leasing in financing fixed assets in agriculture was observed.

Climate risk and green total factor productivity in agriculture: The moderating role of climate policy uncertainty.

In light of the escalating global warming and the escalating frequency of extreme weather events, the agricultural sector, being a fundamental and pivotal industry worldwide, is encountering substantial challenges due to climate change. Using Chinese provincial panel data for 2000-2021, this paper utilizes a two-way fixed-effect model to investigate the impact of Climate Risk (CR) on green total factor productivity in agriculture (AGTFP), with China's climate policy uncertainty (CPU) being introduced as a moderating variable within the research framework to scrutinize its influence in this context. The findings reveal a noteworthy adverse effect of CR on AGTFP, further exacerbated by CPU. Heterogeneity analysis results show that there is a clear regional variation in the effect of CR on AGTFP across different Chinese regions, with CR significantly inhibiting AGTFP development in the northern regions and provinces in major grain producing regions. Consequently, there is a pressing necessity to bolster the establishment of climate change monitoring infrastructures, devise tailored climate adaptation strategies at a regional level, and enhance the clarity and predictability of climate policies to fortify the resilience and sustainability of agricultural production systems.

The impact of labor force aging on agricultural total factor productivity of farmers in China: implications for food sustainability

IntroductionThe rapid aging of the labor force has serious implications for socioeconomic development and poses challenges to food sustainability. Existing studies have focused on the impact of labor force aging on land productivity, but little attention has been paid to the comprehensive capacity of agricultural production, namely the total factor productivity of agriculture.MethodsWe estimate the impact of labor force aging on total factor productivity in agriculture using data from 170,506 sample farm households from the National Fixed Point Survey data from 2003 to 2020. We estimate the results using a panel fixed effects approach and mitigate the endogeneity problem using an instrumental variables approach to ensure the robustness of the estimates.Results and discussionThe results show that labor force aging has an adverse effect on the agricultural total factor productivity of farm households and remains robust after addressing endogeneity and substituting explanatory variables. The aging effect shows significant heterogeneity across different food functional areas with different types of farm households. The negative impact of labor force aging on total factor productivity in agriculture is mainly concentrated in the main grain-production and grain-producing and marketing-balanced areas. We also find that the negative impact of labor force aging is more significant among large-scale farmers. The mechanism analysis finds that the aging of the labor force adversely affects the agricultural total factor productivity by inhibiting technological progress and reducing the efficiency of agricultural resource allocation. These insights, when considered in the light of global trends towards agricultural labor aging, suggest that policy interventions aimed at promoting technological adoption, enhancing resource allocation efficiency, and supporting the transitioning of older farmers may hold promise for maintaining food sustainability and addressing the challenges posed by an aging agricultural workforce in numerous developing nations.

Efficiency of Agricultural Insurance in Facilitating Modern Agriculture Development: From the Perspective of Production Factor Allocation

Agricultural insurance is instrumental in consolidating the gains of poverty alleviation and advancing rural revitalization. It significantly aids in the efficient allocation of agricultural production factors, which in turn enhances agricultural output and bolsters the evolution of modern agriculture. Therefore, utilizing data from 583 household surveys and employing endogenous transformation and intermediary effect models, this paper analyzes the production factor allocation effect and specific mechanism of agricultural insurance. It focuses on small-scale farmers and new agricultural operators, exploring how insurance contributes to the advancement of modern agricultural practices. The results show the following: (1) Agriculture insurance can significantly affect the agricultural scale input behavior of farmers such as land input scale and input scale, agricultural machinery application behavior such as the degree of mechanization and water conservancy application, agricultural technology adoption behavior, and planting structure selection behavior, thereby helping to modernize agriculture. (2) There is heterogeneity in the impact of agriculture insurance on the allocation of production factors for small farmers and new agricultural operators. For small farmers, agriculture insurance has a significant promoting effect on their agricultural machinery application behavior, agricultural technology adoption behavior, and planting structure selection behavior. For new agricultural operators, agriculture insurance significantly promotes their agricultural scale input behavior, agricultural machinery application behavior, and agricultural technology adoption behavior. (3) In terms of the mechanism of action, agriculture insurance mainly promotes agricultural scale input behavior through land transfer, facilitates agricultural machinery application behavior by purchasing agricultural machinery equipment and services, encourages agricultural technology adoption behavior by strengthening agricultural technology training, and enhances professional production levels by increasing the scale of insured planting, thereby contributing to the development of modern agriculture. Based on this, several policy suggestions have been proposed. These include enhancing the directionality of agriculture insurance policies, improving the collaborative interaction mechanism between agriculture insurance and agricultural credit financing, and adopting certain reward and punishment measures to curb moral hazard.

Effect of plant growth-promoting rhizobacteria (PGPR) on growth and yield of shallots on saline soils

Soil salinity is a limiting factor in agricultural productivity. One of the biological approaches to mitigate the impact of salt stress on plants is inoculating plant growth-promoting rhizobacteria (PGPR) to the plant roots. This study aimed to investigate the eff of PGPR dosage on the growth and yield of shallots at various salinity levels. This study was carried out in the experimental field of Poncokusumo, Malang. The treatments tested consisted of two factors. The first factor was soil salinity level, consisting of four levels: no salinity, NaCl 50 mM, NaCl 100 mM, and NaCl 150 mM. The second factor was PGPR concentration, consisting of four levels: no PGPR, PGPR 10 mL/L, PGPR 20 mL/L, and PGPR 30 mL/L. The sixteen treatment combinations were arranged in a randomized block design with three replications. The data obtained were subjected to the analysis of variance (ANOVA) at a significance level limit of 5%, followed by the Honestly Significant Difference (HSD) test at a 5% significance level for any significant differences. The results showed that the application of 30 mL/L of PGPR reduced EC of the soil and improved plant height, plant dry weight, leaf area, bulb diameter, bulb weight, and the number of bulbs per plant by 33%, 47.3%, 81%, 13%, 34.2%, 98.5%, and 31%, respectively, compared to the treatment without PGPR application under NaCl 150 mM salinity. The application of PGPR at 20 and 30 mL/L dosages significantly increased chlorophyll, flavonoid, and proline indices at NaCl at 100 mM and 150 mM salinity levels compared to the treatment without PGPR.

The Role of Climate Change, Employment, Government Expenditure, and Imports on the Value of Agricultural Production in Romania

Abstract Agricultural production is important for ensuring food security, supporting many activities of society and building strong trade economy of a country, but can be slightly influenced by numerous factors. Even if exists a lot of studies that analyze the influencing factors of agricultural production in terms of value, investments, climate change, credits, costs of energy and more, in the literature can be observed a research gap regarding the relation between emissions or mean weekly hours actually worked per employed person and value of agricultural production. The identified gap in the specialty literature was covered in this paper. The present paper aims to analyze a series of factors that influence the value of agricultural production, like: climate change, employment, government expenditure and imports, after discussing the theoretical framework about the subject. The methodological approach is based on using several linear regressions, tested with the EViews software. One of the main findings indicates the existence of relationships between both the change of imports and the change of emissions with the value of agricultural production in Romania during 1995-2021. Also, another result indicates a negative influence of temperature change on the value of agricultural production, showing once again that climate change does negatively impact agricultural output and, thus, the sustainable development of Romania. This study could be used further by policy makers to understand on which drivers should act on in developing sustainable policies for Romanian agriculture.

Seed Production in Jalandhar

A key factor in agricultural resilience, crop diversity, and productivity is seed production—particularly in areas like Jalandhar that must meet changing market demands and climate change. This project explores the complexities of seed production in Jalandhar and how it affects agricultural development with the goal of educating researchers, policymakers, and agricultural stakeholders on how to support sustainable seed production systems. Located in the rich plains of Punjab, Jalandhar has become a major centre for the production of seeds, especially for pulses, wheat, and rice. The region's favorable soil and climate, together with cutting-edge farming techniques, are what propel the expansion of the seed business. With the growing use of hybrid and genetically modified seeds, government programs encouraging agricultural output, and growing farmer awareness of the advantages of high-quality seeds, Jalandhar has a huge market potential for seed production. Nevertheless, in order to fully realize the potential of this industry, stakeholders must work together and implement strategic interventions in response to issues including volatile market pricing, restricted financial availability for small-scale farmers, and environmental sustainability concerns. The sector's growth trajectory is further aided by the existence of well-established agricultural research institutions and government policies that are supportive of the industry, providing growing opportunities in both domestic and foreign markets High-quality seeds improve crop yields while also contributing to overall sustainability and profitability in farming operations. Agro-ecologically-suited certified seeds are essential for reducing the danger of pests, illnesses, and unfavorable weather. Encouraging and supporting sustainable seed production systems in Jalandhar benefits all related departments and financial institutions by promoting agricultural development, economic success, and food security.

Nickel iron mining slag and soil acidity correction

Soil acidity is one of the limiting factors of agricultural production most commonly reported in oxidic soils, such as Oxisols often found in the Brazilian Cerrado regions for example. The dredging is the most efficient management practice in the correction of soil acidity and increase of base saturation levels. The nickel iron mining scora is a residue that has relevant amounts of magnesium silicate, and may have neutralization capacity of soil acidity. Therefore, the objective of this work was to value the potential of magnesium silicate as a soil acidity corrective. The experimental design used was completely randomized, arranged in a 2x5x5 factorial scheme with twelve replications, where the 1st factor consisted of two hatching dates, 30 and 60 days, the 2nd factor consisted of five doses of mining slag: 0, 90, 120, 150 and 180 Mg ha-1, and the 3rd factor consisted of five doses of dolomític limestone: 0, 90, 120, 150 and 180 Mg ha-1. The mining slag did not present soil pH neutralization power under the evaluated conditions. However, it presented potential for neutralization under conditions of lower granulometry and greater solubilization.

Spatial Distribution Characteristics and Influencing Factors of Geographical Indication Agricultural Products in Shaanxi Province

Geographical indication agricultural products are of great significance to promote the high-quality development of rural revitalization due to their unique quality and brand value. Based on the geographical concentration index, the nearest neighbor index and the kernel density estimation method, this paper empirically studies the spatial distribution characteristics and influencing factors of 117 geographical indication agricultural products in Shaanxi Province. The results show that the spatial distribution of geographical indications in Shaanxi is extremely uneven, showing the characteristics of ' dense in the south and sparse in the north, regional agglomeration '. From the perspective of density distribution characteristics, the overall spatial distribution of geographical indications in Shaanxi shows a distribution pattern of ' three high and three times ', and the three high-density areas show a agglomeration distribution pattern of ' pin-shaped '. The difference between the north and the south is obvious, and the overall distribution pattern is ' cold in the north and hot in the south '. The spatial distribution pattern of geographical indications in Shaanxi is affected by many factors. Natural factors are the basis, social and economic factors strengthen the spatial distribution pattern of geographical indications, and government-led and policy factors play a regulatory and guiding role. It is suggested to optimize the spatial distribution pattern of geographical indications in Shaanxi, rely on local social resources, give full play to the leading role of the government, and actively promote the industrialization development of geographical indication products.

Agromet Advisories to Mitigate the Effects of Aberrant Weather in Himachal Pradesh

Weather is a pivotal factor in agricultural production, influencing crop growth, disease and pest occurrences, water and fertilizer needs, and the effectiveness of cultural and preventive measures. Extreme weather events can cause physiological stress, physical damage, soil erosion, and crop quality degradation. In India, agriculture's vulnerability to adverse weather is a significant concern, with natural disasters like floods, droughts, and cyclones leading to crop failure, food insecurity, and economic impacts. To mitigate these challenges, Agrometeorological Advisory Services (AAS) play a crucial role in providing farmers with weather-based advisories to manage agricultural risks. The Integrated Agro-Meteorological Advisory Service (IAAS), run by the Indian Ministry of Earth Sciences and the India Meteorological Department (IMD), offers district-level weather forecasts and agromet advisories to support farmers in adapting to weather fluctuations. These advisories cover various weather-related risks, including cold injury and frost, high temperatures, wind damage, hailstorms, and floods. Sample advisories suggest measures like irrigation for frost protection, mulching to reduce heat stress, and shelter belts to mitigate wind damage. Effective dissemination of advisories involves communication through electronic media, Krishi Vigyan Kendras (Agriculture Science Centres), and Kisan (Farmer) Call Centres. Thrust areas for enhancing AAS include improved scientific understanding, advanced monitoring and prediction of severe weather events, satellite-based communication technologies, and real-time forecasting. By integrating these strategies, farmers can better prepare for extreme weather and mitigate its impact on agriculture.

MEASURING THE AGRICULTURAL TOTAL FACTOR PRODUCTIVITY OF PROVINCES IN TURKEY USING MALMQUIST INDEX

This study aims to reveal the total factor productivity levels in the agricultural sector in 81 provinces of Turkey by using the Malmquist index method over the period 2009-2019. The results extracted from the Malmquist index findings show that index value changed between 1.186 and 0.952, agricultural productivity increased in 75 provinces and decreased in 6 provinces.

From a policy perspective, the results suggest that authorities in Turkey should develop and implement technologies that will make the sector productive, to encourage and support infrastructure, research and publication studies on technology. In addition, this research claims that the regional incentive system can be revised and, it can build an incentive system based on performance and efficiency in which provinces or businesses operating in this field are classified according to their productivity.

Integrating the rent gap into the ground rent theory. Measurement and implications for different models of agriculture

The aim of this paper is to establish a conceptual framework for the rent gap theory in agriculture and to identify potential implications of the rent gap for socio-economic processes occurring in agriculture and rural areas. From an empirical perspective an attempt was made to determine the state and dynamics of the rent gap phenomenon in agriculture in Poland, considering the regional division. The authors used income approach and Capital Asset Pricing Model (CAPM) for estimating the capitalization rate. It was found that rent gap is a permanent phenomenon in Polish agriculture, the dynamics of which largely depends on macroeconomic factors. A widening rent gap may result in the withdrawal of land from farming and a decline in total factor productivity in agriculture. Thus, the implications of the rent gap may relate to food security. Measuring the rent gap can be a step towards determining the quasi-market value of environmental amenities of land.

Potential of Eco-Weeding with High-Power Laser Adoption from the Farmers’ Perspective

Agriculture and rural regions in Europe face a number of economic, social, and environmental challenges. Rural areas are active players in the EU’s green transition. Weeding is one of the most important factors in agricultural production. New weeding techniques are being developed to enhance sustainability. Among them, laser-based weeding seems to be a promising alternative to the use of chemicals. The WeLASER technique is a novel technique for weed control. Its successful implementation depends on many factors related to the innovation itself, policy context, farming conditions, and users’ attitudes. A survey was carried out to provide insight into the attitudes towards the innovative (laser) weed control tool (autonomous robot). The CATI method was selected for the surveying of farmers’ opinions and carried out in three countries: Denmark, Spain, and Poland. Statistical methods were applied to analyze the results. This study provided knowledge on how farmers see the barriers and opportunities related to implementing the device in practice. Positive attitudes of farmers were observed but with high expectations related to the quality of the technique and the systemic conditions of its implementation.

SUSTAINABILITY REPORTING AS A TOOL FOR ATTRACTING INVESTMENTS FOR THE GREEN RECONSTRUCTION OF UKRAINE’S AGRIBUSINESS

Introduction. Global trends in the decarbonization of production and the development of the green economy prove that the principles of sustainable development have become a key reference point for making management decisions. Ukrainian agribusiness suffered huge losses due to military actions, so significant funds are needed for its reconstruction. To attract foreign investments, agricultural enterprises must prove their commitment to sustainable development goals by disclosing relevant information in the reporting. Purpose. The article aims to substantiate the practicality of preparing and publishing the Report on Sustainable Development as a tool for attracting investments for the green reconstruction of Ukraine's agricultural sector and to reveal its information content. Methods. The paper uses an abstract-logical method to substantiate the benefits of reporting on sustainable development by agricultural enterprises. Based on the application of methods of analysis and synthesis, induction and deduction, and logical generalization, the content (indicators) of the Report on Sustainable Development and Investments was revealed. Using the analogy method made it possible to strengthen the justification of the importance of sustainability reporting in Ukraine based on the EU countries' experience and the agribusiness need for foreign investments. Results. The paper systematizes the indicators of the Report on Sustainable Development and Investments in the agricultural sector and reveals some aspects of the normative regulation of sustainability reporting. An analysis of the factors of agricultural production was carried out, the disclosure of which in the Report on Sustainable Development will increase the agricultural enterprise's investment attractiveness and testify to its desire to be more open (accountable) to society. Conclusion. Sustainability reporting can be a tool for an agribusiness to better understand its impact on the environment and risks and manage them more effectively, successfully use new opportunities and solve specific challenges to become a leader in sustainable development. The Report on Sustainable Development and Investments in the agricultural sector ensures greater transparency of the enterprise's activities. It demonstrates to interested parties and the public its commitment to the principles of sustainable development, which increases the chances of successfully attracting external financing – foreign investments.

Value chains of selected products as elements of sustainability of agricultural production

The value chain concept is often used in the analysis of agricultural competitiveness. Its application seeks ways and activities that add value to products. The focus is on finding opportunities for efficient monitoring of modern trends, challenges and business risk assessment in order to sustainably produce processing and marketing of agri-food products. The production of fruits and vegetables by small producers is characterized by short chains from production to product placement, without adding value. There are numerous critical points in the analyzed chains, such as quality of input, processing, drying and storage of products, lack of training and financial resources for storage and preservation of products after harvest. The link between primary production and the processing industry should ensure stability for primary producers in terms of the market, and entities in the processing industry for continuity in the supply of raw materials of domestic origin. In order to improve product value chains, and thus the competitiveness of the national agri-food sector, it is necessary to improve productivity in primary production, horizontal and vertical integration, as well as additional investments in processing capacities. The key areas in the legislation and its implementation in order to improve the value chain of livestock products are: animal husbandry, hygiene on farms and in meat processing plants, as well as environmental protection. These are some of the priorities that should create the conditions for the possibility of exporting live animals, meat and meat products to the EU. Improving the milk value chain would contribute to better efficiency, competitiveness and sustainability of production, milk quality, especially in microbiological terms (reduction of the number of bacteria and somatic cells). Conditions should be created for the adoption of good agricultural practice, adaptation to market requirements, reaching standards in the field of animal welfare and health, improving the genetic potential of animals for milk production, hygiene and environmental protection. Quality is an important factor in competitiveness and sustainable agricultural production. As the main elements of the quality management system and adding value to products, the appropriate standards are applied: ISO 9000, HACCP, GMP, ISO 22000, ISO 14000, HALAL standard, Kosher standard, BRC standard, GOST-R standard, Demeter, GLOBAL GAP, IFS standard . In order to overcome and solve environmental problems of agricultural development, more and more importance is attached to the application of animal protection policy measures. Domestic and international standards and regulations for environmental management ISO 14001 are applied, including the EU Environmental Management and Audit Scheme (EMAS). Genetic potentials and biological diversification are important for the development and sustainability of agricultural production. The richness of flora and fauna, genetic resources and great biological diversity constitute natural comparative advantages in every respect, especially for sustainable agricultural production and environmental protection.

Effect of different soil moisture regimes on yield and water use efficiency of groundnut at Kobo irrigation scheme, Kobo Ethiopia

In the arid and semi-arid part of Eastern Amhara, water is the most important yield-limiting factor for agricultural production. Application of the right amount of irrigation water at a right time helps to optimize water loss and increases crop yield. Therefore, a field experiment was conducted at Kobo irrigation scheme to determine the optimal crop water requirement and irrigation frequency for yield and water use efficiency of groundnut. The CROPWAT model could generate the 100% irrigation scheduling as 40 mm irrigation water with 8 days. Field base validation and ground truthing is vital. Therefore, the treatments were formulated by the factorial combinations of the three crop water levels as 75% ETc (30 mm), 100% ETc (40 mm), 125% ETc (50 mm) with three irrigation intervals (6 days, 8 days and 10 days). The treatments arranged in randomized complete block design with three replications. The statistical analysis was carried out using Genstat 15.0 software and the mean comparison was done using least significant difference (LSD) test. The analysis revealed that the crop water use efficiency was significantly (p<0.05) affected by the main effects of crop water levels, irrigation interval and by their interaction, whereas the grain yield does not show a significant (p>0.05) response. As the water levels declined and the irrigation intervals varied, the grain yield tends a fairly constant trend. However, based on the commerciality of the crop, application 75% ETc (30 mm) with 8 days irrigation interval gave numerically maximum grain yield of 3466.9 kg/ha and it has nearly more than 200 kg relative yield advantage over most treatments. The highest water use efficiency (0.9 kg/m3) was recorded from the combination 75% ETc (30 mm) with 10 days; while it was statistically at par with 75% ETc with 8 days interval (0.8 kg/m3) applied treatment. From the result, it could be concluded that the maximum yield and maximum water productivity were simultaneously achieved by combined application of 75% ETc with 8 days interval and saves 4600 m3 water to irrigate an additional 1.2 ha compared with 125% (50 mm) ETc with 6 days interval applied treatment.
