A Study on Production and Marketing Constraints of French Bean (Phaseolus vulgaris L.) Growers in Bishnupur District of Manipur

The study was conducted to analyze the production and marketing constraints of French beans in the Bishnupur district of Manipur. The primary data was collected through a personal interview technique from 100 respondent farmers. Garrett's ranking technique was used for the analysis. Higher cost of labor, pesticide and fertilizer, inadequate irrigation facilities, high seed cost, non-availability of labor, credit, and seed on time, and lack of technical guidance and credit facilities were the main constraint’s found during the production. In case of marketing constraints, price fluctuation high perishability of the produce, high transportation cost and lack of transportation and storage facilities, presence of an exploitative middleman, bandhs and strikes, untimely payment of sale, lack of price and market information, and absence of regulated markets were the major constraints. These constraints are giving huge hindrances to the farmers during the production and marketing and hence proper remedies should be imposed so that the production and marketing of this particular crop can be improved efficiently.

Effects of haze pollution on pesticide use by rice farmers: fresh evidence from rural areas of China.

Recently, severe haze pollution has not only threatened human health and food security, but also seems to have aggravated the unscientific use of pesticides by rice farmers in rural areas of China. Using original data on haze pollution across China, combined with rural household survey data collected from 2014 to 2018, we conducted a detailed empirical study on the effects of haze pollution on pesticide use by rice farmers based on the theory of risk aversion. The empirical results revealed that haze pollution with higher levels of PM2.5 positively impacted the use of chemical pesticides in rice cultivation. More precisely, with each 100% increase in PM2.5 concentrations, the use of pesticide per mu increased by 7.9%, and the average pesticide cost per mu increased by 2.3%. The results were robust to a series of tests that addressed potential endogeneity concerns, including omitted variable bias, measurement error, and reverse causality. We then examined the heterogeneous effects of haze pollution increases on the use of chemical pesticides and found that for rice farmers without rice insurance, haze pollution has a stronger effect on pesticide use and a weaker effect on pesticide cost. However, for rice farmers with more experience in rice cultivation and small-scale rice planting, the effect of haze pollution on pesticide use and cost is relatively small. Our findings provide important policy implications for pesticide risk management in rural areas of developing countries.

Costs to Ecuador's rice sector during the first decade of an apple snail invasion and policy recommendations for regions at risk

Invasive Alien Species (IAS) can become a tremendous burden to national economies; however, few studies have quantified the economic impacts of IAS, particularly for developing nations. The golden apple snail, Pomacea canaliculata (Lamarck), was introduced into Ecuador in 2005. By 2012, the snail had affected 94% of Ecuador's rice-growing areas. We used government surveys of rice production and snail distributions, as well as yearly production costs and rice prices, to estimate snail-associated losses to rice productivity and profitability between 2005 and 2015 – the first decade of P. canaliculata in Ecuador. Based on the intensity of the invasion and changing management practices, we estimate that the golden apple snail caused accumulated losses of 35.65 K tons of rice grain (worth US$23.10 M) with further productivity losses (lost inputs and labour) of US$9.61 M (total = US$32.71 M), until 2015. Based on survey information, we estimate that 90% of affected fields were treated with pesticides during the 5 years following initial establishment of the snail on individual rice farms. Pesticides potentially saved up to $10 M in damage during peak snail densities in 2012. By 2015, prophylactic molluscicide treatments were costing the nation US$15.24 M annually (including application costs: accumulated 10-year cost = $123.46 M, assuming 90% coverage). Increasing pesticide and labour costs, but relatively stable farm-gate rice prices, suggest that the continued chemical control of golden apple snail in Ecuador is economically unsustainable. We discuss possible alternatives to prophylactic molluscicide applications that can increase the economic and environmental sustainability of rice production in the face of high densities of apple snails during post-introduction outbreaks. We suggest that nations at high risk from invasive apple snails (e.g., Bangladesh, India, Colombia and Peru) could avoid substantial losses by pre-emptively researching and adopting mechanized crop establishment practices that not only reduce labour costs, but also prevent potential damage from apple snails to rice.

The Impact of Non-Green Forces on Net Present Value and Green Net Present Value: A Study on three Agricultural Crops

This paper aims to justify the impact of environmental factors on net present value (NPV) and green net present value (GNPV). The study takes 201 samples of family farms, including three crops such as paddy, corn, and potato. This paper adopts regression models and mediating effects to determine the impact of non-green forces on the environment and its consequences on the financial performance of agriculture farms. Empirical findings indicate that fertilizer cost, pesticide cost, air pollution cost, and water pollution cost have a statistically significant impact on evaluating net present value and green net present value for the production of paddy and corn. However, none of the non-green forces have a statistically significant impact on potato production. Furthermore, pesticide cost has a mediating effect on the net present value of paddy and potato cultivation, while only fertilizer cost affects the net present value of corn production. The empirical findings inspire governmental authorities, policymakers, agriculturists, and other stakeholders to develop alternatives to enhance productivity and profits considering the environment.

Short supply chain participation, and agrochemicals' use intensity and efficiency: evidence from vegetable farms in China

PurposeOveruse of chemical fertilizers and pesticides is a major policy concern for many countries. Chinese government has adopted many technologies and management practices to reduce their use. However, little is known about the effects of social-economic method such as short supply chain (SSC) participation. SSC is an important organizational innovation in fresh food supply chains aiming at directly connecting farmers and consumers. Closer relationships between farmers and consumers may result in production behavioral changes. Thus the purpose of this paper is to investigate the impacts of SSC participation on agrochemicals application.Design/methodology/approachBased on the household level data collected from Jiangsu province in China, this paper employs an instrumental variable (IV) method to address the self-selection bias when we evaluate the effects of SSC participation on use of chemical fertilizer and pesticides. In addition, this paper also distinguishes between growth inputs and facilitating inputs in the production function when we calculate the marginal production values of chemical fertilizer and pesticides.FindingsThe empirical results show that SSC participation significantly reduces chemical fertilizer use by 351 kg and pesticides costs by 1659 Yuan (RMB) per hectare, accounting for 43.4% of the average chemical fertilizer use and 49.4% of the average pesticide costs, respectively for Chinese vegetable farms. However, SSC participation still cannot improve the use efficiency of agrochemicals.Originality/valueThis paper uses both application quantities and allocation efficiencies of chemical fertilizer and pesticides to comprehensively evaluate the effects of SSC participations. The results will reveal the core role of SSC played in promoting sustainable development of Chinese agricultural sector dominated by small-scale farmers.

Supply Chain Analysis of Raw and Value-added Products of Tomatoes in Telangana

Tomato (Solanum lycopersicum L.) is one of the most widely consumed vegetable crops and the second-largest cultivated vegetable crop in the world after potato. Tomato is one of the most important protective foods because of its special nutritive value. Tomatoes grown in the country are consumed fresh in raw or cooked form or processed into tomato paste, juice, sauce, ketchup, soup and, pickles. Less than one percent of India’s tomato production is processed. On the other hand, the demand in India for processed tomato products has been growing at an annual rate of about 30 per cent over the last few years. India is the World's largest producer of many fruits and vegetables but there still exists a huge gap between per capita demand and supply due to enormous wastage during post-harvest storage, handling, and the absence of an optimum supply chain. The price fluctuations in tomatoes are very high and often farmers are forced to sell at prices that will not cover even the labor cost of picking the tomatoes. A well-developed tomato processing industry will reduce wastages as well as secure better prices for tomatoes. The present study entitled “Supply chain analysis of raw and value-added products of tomatoes in Telangana” was intended to assess supply chain analysis for raw and processed tomato products along with the constraints faced by each stake holder in the supply chain. Vikarabad district was purposively selected for the study, two mandals four villages each were selected from each village, data was collected from 10 farmers. Hence the total data was collected from 80 farmers. The data was also collected from commission agents, wholesalers/ traders, and retailers. From the tomato processing firms operating in around Hyderabad, three firms were selected to collect data regarding their products and marketing supply chain. The collected data was analyzed.
 The results of the study identified three channels of raw tomato marketing, namely: channel-I Farmer- Commission Agent-Trader-Retailer-consumer, Channel-II Famer – Commission agent - Retailer-consumer and Channel-III Farmer- Retailer-consumer. Two channels of processed tomato products were identified, namely: Channel-I, Manufacturing unit- wholesalers-consumers and Channel-II, Manufacturing unit- consumers.
 The producer share in the consumer rupee was highest in the Channel -III because of lesser number intermediaries. The marketing efficiency is highest for the channel – III fallowed by channel – II and channel -I. In case of processed industries are mostly preferring channel -II. The major constraints to the farmers identified were high price fluctuations, high cost of fertilizers and pesticides. The major constraints to the intermediaries identified were high price fluctuations and transportation costs and problems. The major problems identified were lack of quality raw materials suitable for processing, and price fluctuations of raw materials for the processing units, while the major problems faced by wholesalers identified were timely availability and quality related issues.

Determinant Factors of Income of Cocoa Farmers in Batuparigi Village, Mamuju Tengah District

Cocoa farming is a business developed by the community in Batuparigi Village, Tobadak District, Central Mamuju Regency so that cocoa is one of the leading agricultural sectors there. However, there are several inhibiting factors, such as; The increasing price of cocoa seedlings has made it difficult to obtain quality seeds. In addition, the cost of fertilizers and pesticides has increased in price from year to year and has become an obstacle for cocoa farmers. This study uses a quantitative approach with a survey method. The sample in the study was 30 people. The data collection techniques used were observation, documentation, and questionnaires. The data analysis technique used is multiple linear regression analysis. The results showed that simultaneously the independent variables (land area, fertilizer costs, seed costs, pesticide costs, and labor) had a significant and positive effect on the dependent variable (farmer income). Partially, land area has a significant effect and is positively related, while the variable cost of fertilizer, cost of seeds, cost of pesticides, and labor has no significant effect on farmers' income

Ethnoecology of Zanthoxylum acanthopodium by local communities around Lake Toba, North Sumatra, Indonesia

Abstract. Nurlaeni Y, Iskandar J, Junaedi DI. 2021. Ethnoecology of Zanthoxylum acanthopodium by local communities around Lake Toba, North Sumatra, Indonesia. Biodiversitas 22: 1806-1818. Zanthoxylum acanthopodium DC., locally known as andaliman, is a typical spice of traditional cuisine of communities living around Lake Toba, North Sumatra, Indonesia. Despite the extensive uses, the ethnoecological study on this plant is relatively scarce. This study aims to conduct ethnoecological studies of the management and cultivation of andaliman plants based on Traditional Ecological Knowledge of local communities of Salaon Dolok Village, a village nearby Lake Toba which has close relationship and intensively cultivated/utilized andaliman in their daily life. This study applied qualitative methods using the combination of direct observation and interviews with 46 selected respondents using snowball sampling. The results of this study showed that the cultivation of andaliman in Salaon Dolok Village was carried out using traditional ways with simple farming practices. These traditional farming models relied on manual farming practices in all farming aspects. The community has local knowledge related to the management of reliable agricultural systems from generation to generation. Andaliman cultivation in Salaon Dolok Village does not need maintenance costs for fertilizers and pesticides. In general, andaliman planting is mostly done in the forest. In general, the people of this village only recognize two kinds of andaliman cultivars, namely Andaliman 'Simanuk' and Andaliman 'Sihorbo'. The planting is usually carried out during the rainy season to reduce the mortality rate of the planted seedlings. The activity of seedling preparation is carried out in two simple ways. First, most farmers were collected andaliman seeds that grow wild around the existing andaliman plants. The second method is by collecting the seedling that grows from the burning land with some remains of old andaliman plants collected at the edge of the land. Sustainable agriculture should minimize the external input from outside of the agro-ecosystem. Low External Input Sustainable Agriculture (LEISA) emphasizes the efficient use of existing production factors to create sustainable agriculture, including for andaliman agriculture system.

Impact Evaluation of the System of Rice Intensification Scheme in Chhattisgarh

The study was conducted in Chhattisgarh to compare the cost and return of rice in adopters and non-adopters and identify constraints in adopting the SRI technology. The total labour cost was highest in adopters than non-adopters, and input cost was ( 8723.42) in adopters and was less than non-adopters ( 9772.75). It was also found that the cost of adopters' cultivation was ( 49885.17) higher than non-adopters ( 41241.82). The result showed that the yield of adopters (67.34 q/ha) was higher than the non-adopters (49.66 t/ha). The gross and net incomes were higher on adopters' farms than non-adopters. The benefit-cost ratio was higher in adopters (1:2.03) than non-adopters (1:1.82). Timely availability of skilled labour (62 percent) with higher than more labour requirement (50 percent), unavailability of implements (48 percent), lack of training (46 percent), drudgery in using cono-weeder (40 percent), unskilled transplanting (34 percent) and improper nursery management (30 percent) the other constraints were assured irrigation, lack of farm mechanization high cost of pesticides, high cost of manures and fertilizers. The primary suggestion regarding the SRI method of paddy cultivation was to develop chemical and mechanical weed control and ensure the availability of cono-weeder and marker in the market. Timely guidance should be given by the concerned persons in the transfer of technology to the farmers' field of immense help in this direction.

Agricultural technical education, interpersonal trust, and pesticide use by vegetable farmers in China

ABSTRACT Purpose Agricultural technical education is widely used in Chinese agricultural production to reduce farmers’ pesticide overuse. However, the effectiveness of technical education is questioned by scholars who found that it fails to promote farmers’ pesticide management. In this study, we aimed to explore whether farmers’ interpersonal trust in education staff affects the efficiency of technical education. Design/methodology/approach A questionnaire-based cross-sectional study was conducted on Chinese vegetable farmers with 117 open field vegetable growers and 119 greenhouse vegetable growers. Data were analyzed using a multivariate regression model. Findings The results show that technical education can significantly reduce farmers’ pesticide application in vegetable production. And the effect of specific guidance is stronger than that of course training. The response of farmers on technical education, as a proxy of farmers’ understanding capacity on education knowledge, negatively affects farmers’ pesticide costs. More importantly, we find that farmers’ trust in education staff could affect the positive effect of agricultural technical education on pesticide application. Practical implications This study will enable education staff/officers to value interpersonal relationships, which can instruct farmers to turn the pesticide knowledge they received from technical education into production practice. Theoretical implications Promoting farmers’ trust in information providers will increase the efficiency and quality of knowledge transmission and transformation in agricultural technical education. Originality/value This paper highlights the importance of interpersonal trust in agricultural technical education, and offers an available explanation for controversy over on efficiency of agricultural technical education.

Pest Activity and Protection Practices: Four Decades of Transformation in Quebec Apple Orchards.

Simple SummaryCommercial orchards from Quebec (Canada) were followed for over 40 years to track patterns of activity of major fruit pests, fruit damage and impacts (environmental and financial) of pesticide applications. Some insects (as expected) were more prevalent in the insecticide-free orchard than in commercial orchards, while others were (surprisingly) more prevalent in commercial orchards or as prevalent in both orchard types. Annual fruit damage in the insecticide-free orchard was extremely high (as much as 98% for a single pest) and mostly from the apple maggot, the plum curculio and the codling moth. In commercial orchards, fruit damage was ten times less important and mostly from the plum curculio, the tarnished plant bug and the oblique-banded leafroller. The number of registered pesticides, the number of applications and the total cost of pesticides gradually increased from 1977 to 2019, while the environmental and health risks followed a downward trend for most pesticide categories. The historical trends presented here were likely modulated by external factors such as the pesticide regulatory framework, the arrival of non-native insects and climate change.A group of commercial orchards from Quebec (Canada) was followed from 1977 to 2019 as part of a project to implement Integrated Pest Management (IPM) practices. Collected data comprised activity of major fruit pests (from monitoring traps), fruit damage at harvest and pesticide applications, from which the annual costs and impacts of protection programs over 42 years were calculated. Activity and fruit damage in commercial orchards were compared to patterns observed in a reference insecticide-free orchard. Some insects (European apple sawfly, codling moth, apple maggot) were more prevalent in the insecticide-free orchard than in commercial orchards, while others were more prevalent in commercial orchards (oblique-banded leafroller) or as prevalent in both orchard types (tarnished plant bug). Annual fruit damage in the insecticide-free orchard was mostly from the apple maggot (up to 98%), the plum curculio (up to 90%) and the codling moth (up to 58%). The average situation was different in commercial orchards, whose damage was mostly from the plum curculio (up to 7.6%), the tarnished plant bug (up to 7.5%) and the oblique-banded leafroller (up to 1.7%). While the number of registered pesticides, the number of applications and the total cost of pesticides gradually increased from 2002 to 2019, the risks incurred, as measured by indicators of environmental and health impacts, followed a downward trend for insecticides and acaricides and varied slightly for fungicides.

Chemical characterization of an aqueous extract and the essential oil of Tithonia diversifolia and their biocontrol activity against seed-borne pathogens of rice

The high cost of chemical pesticides and their negative impact on the environment prompted the search for natural pesticides from plants. The objective of our study was to control rice seed pathogenic fungi and bacteria using aqueous extract and essential oil from Tithonia diversifolia leaves. We obtained aqueous extract and essential oil, respectively, by maceration and hydrodistillation; the antimicrobial activities were determined in vitro on a solid medium by the food poisoning method. The secondary metabolites were determined by qualitative and quantitative assays; the chemical composition of the essential oil obtained from Titonia diversifolia was studied using gas-chromatography coupled with mass spectrometry. The results showed that phenols, tannins, flavonoids, alkaloids, terpenoids, sugars and saponins were present in the aqueous extract. The essential oil contained mainly hydrocarbonated, oxygenated monoterpenes, terpenoids and sesquiterpenes. α-terpineol (20.3%), eucalyptol (14.6%), camphor (14.3%) and α-pinene (13.5%) as the main compounds. Regarding the antimicrobial activity, all tested bacteria were sensitive to aqueous extract and essential oil. The activity of the aqueous extract on the tested fungi showed an inhibitory concentration 50 (IC50) of 50 mg/mL against Bipolaris oryzae and Fusarium moniliforme. The activity of the essential oil on bacteria and fungi showed MIC of 125 μg/mL (Xanthomonas oryzae pv. oryzae and Pseudomonas fuscovaginae) and MFC of 5000 μg/mL (Bipolaris oryzae and Fusarium moniliforme). These results allow us to consider Tithonia diversifolia as a potential source of natural biopesticides against rice seed-borne pathogens.

The efficiency of dryland farming in Panggang Forest KPH Yogyakarta

Dryland farming is still to be a main activity of the community around the part of Forest Area (Bagian Daerah Hutan/BDH), Panggang, Kesatuan Pengelolaan Hutan (KPH) Yogyakarta. This study aimed to determine the efficiency of dryland farming and the factors that influencefarming income. The survey method was used to carry out farming data and information by interview the farmer. The R/C analysis, labor productivity analysis, and capital productivity analysis were used to determine the efficiency of dryland farming. Furthermore, to determine the effect of production input factors on farming efficiency, a multiple linear regression analysis was carried out. The results showed that dryland farming by the community around BDH Panggang forest was not efficient because the value of R/C<1 (0,44), labor productivity Rp 29.522,69/working people’s day is lower than a local standard wage Rp 50.000/ working people’s day, and the productivities of land and capital are negative value. The factors production, land area, seed cost, fertilizer cost, pesticide cost, and labor have simultaneously impacted the farmers’ income for dryland farming. The factors of seed cost have been a significant effect on the farmers’ income in dryland farming.

Systematic Water-Saving Management for Strawberry in Basic Greenhouses Based on the Internet of Things

A new application of the internet of things in a low-cost greenhouse with no networked intelligent control equipment.The systematic water-saving management focused over the whole growth stage of crops, and it can effectively increase yield and quality.Replace some chemical fertilizer with fully-decomposed organic fertilizer and new types of fertilizer to reduce negative impact on soil and the environment.Regarding pesticide usage, we advocate prevention first and treatment second.Improve systematic water-saving management with regard decreases in crop yield and quality.Abstract. A basic greenhouse is an inexpensive type of greenhouse, which lacks networked intelligent control equipment; it is currently the most common type of greenhouse used in China. To manage planting activities intelligently and improve water use efficiency in these greenhouses, an intelligent planting management platform for strawberry based on the internet of things (IoT) is developed. On the platform, human-computer interaction occurs through the WeChat app on a mobile phone so that manual control of the strawberry environment in the greenhouse can be conducted. In this study, we add a user module in the perception layer of the IoT to obtain the information and manually control the environment in a basic greenhouse. The network layer uses narrowband IoT wireless transmission technology based on 4G. The application layer is designed with a systematic water-saving management knowledge base for strawberry. The systematic water-saving management feature includes seven parts: strawberry variety selection, planting seedlings, flower and fruit thinning, environmental control, disease and pest prevention and treatment, fertilizer management, and water-saving irrigation. Through the human–computer interaction platform, growers can receive decision-making options, planting management evaluation, query information retrieval, and regular relevant planting information. The application results of the platform showed the following: compared with management experience of growers, the water use efficiency of yield (WUEy) increased by 128.55%, the water use efficiency of production value (WUEpy) increased by 226.31%; the amount of chemical fertilizer decreased by 40%, the amount of pesticide decreased by 61.67%, and the cost of pesticide decreased by 32.48%; thus a decrease in the use of both fertilizer and pesticide was achieved. This study can directly provide technical support for strawberry intelligent management in basic greenhouses, and can also be used as a basic platform intelligent management systems for other crops grown in basic greenhouses. Keywords: Basic greenhouse, Intelligent agriculture, Internet of things, Sensor network , Systematic water-saving management, Water-use efficiency.

Effectiveness of Conservation Crop Rotation for Water Pollutant Reduction from Agricultural Areas.

Legumes included in corn-based crop rotation systems provide a variety of benefits to the subsequent crops and potentially to the environment. This review aims to synthesize available data from the literature on legume N credits and the effects of crop rotations on water quality, as well as to analyze the cost benefits associated with different legume-corn rotation systems. We found that there was much variation in reported values for legume N credits to subsequent corn crops, from both empirical results and recommendations made by U.S. land grant universities. But despite inherent complexity, accounting for this contribution is critical when estimating optimal N fertilizer application rates as part of nutrient management. Results from research on the influence of crop rotations on water quality show that including legumes in corn-based rotation systems generally decreases nitrate-N concentrations in subsurface drainage discharge. Our cost analysis showed that incorporating legumes in cropping systems reduced N fertilizer and pesticide costs compared to conventional cropping systems, i.e., continuous corn and corn-soybean rotations, but extended rotations, such as corn-soybean-alfalfa-alfalfa-alfalfa, are not as profitable as conventional systems in the U.S. Midwest. In comparing continuous corn and corn-soybean rotations, although their impacts on water quality are not significantly different when using overall means from the literature data, corn-soybean rotations are more profitable than continuous corn. When using data from papers that directly compared the two, we found that switching from continuous corn to corn-soybean can provide a benefit of $5 per kg N loss reduction. The cost analysis methods used could be tailored to any location or management scenario with appropriate inputs and serve as a useful tool for assessing cost benefits for other agricultural conservation practices. Legume-corn crop rotations have the potential to be an effective conservation practice with the ultimate goal of improving water quality, and, with further research, these rotations could be made even more effective by integrating them into a multi-practice system.

Constraints in Production, Marketing and Processing of Onion (Allium Cepa L.) in Nuh District of Haryana

Onion (Allium cepa L.) is one of the important commercial vegetable crops grown in India. The present study was conducted in Nuh district of Haryana on the basis of highest production of onion among other districts of the state. The block named Tauru was selected for sampling and a total of thirty onion farmers from various villages in this block were selected randomly. The primary data for the agriculture year 2017-18 were collected by personal interviews of the selected farmers with the help of specially designed schedule. The results of the study revealed that the major problems faced by the onion farmers in production were observed high cost of pesticide (93.33%), lack of knowledge about recommended fertilizer doses (86.67%), high cost of fertilizer (83.33%), lack of knowledge about the control measures for various pests and diseases (83.33%), difficulty in identifying the pests and diseases (80.00%) and lack of knowledge about seed/seedling treatment (76.67%). As for as marketing of onion is concerned, 83.33 per cent of respondents opined that high cost of transportation, absence of minimum support prices (83.33%), existence of large number of intermediaries in marketing process (83.33%) and too much fluctuation in prices (80.00%). The problems related to processing expressed by onion growers 80.00 per cent of the respondents reported the problem of technical manpower, higher charges of power and fuels (73.33%), fluctuation in raw material and procurement (73.33%) and lack of good quality packaging material (66.67%).

The Impacts of GM Foods: Results from a Randomized Controlled Trial of Bt Eggplant in Bangladesh

We implemented a cluster randomized controlled trial to assess the impact of genetically modified eggplant (Bt brinjal) in Bangladesh. Our two primary outcomes were changes in yield and in pesticide costs. Cultivation of Bt brinjal raises yields by 3,564 kg/ha. This statistically significant impact is equivalent to a 51% increase relative to the control group. There is a statistically significant fall in pesticide costs, 7,175 Taka per hectare (85 USD per ha), a 37.5% reduction. Yield increases arise because Bt farmers harvest more eggplant and because fewer fruits are discarded because they are damaged. Bt brinjal farmers sell more eggplant and receive a higher price for the output they sell while incurring lower input costs, resulting in a 128% increase in net revenues. Bt brinjal farmers used smaller quantities of pesticides and sprayed less frequently. Bt brinjal reduced the toxicity of pesticides as much as 76%. Farmers growing Bt brinjal and who had pre‐existing chronic conditions consistent with pesticide poisoning were 11.5% points less likely to report a symptom of pesticide poisoning and were less likely to incur cash medical expenses to treat these symptoms. Our results are robust to changes in model specification and adjustment for multiple hypothesis testing. We did not find evidence of heterogeneous effects by farmer age, schooling, or land cultivated. Bt brinjal is a publicly developed genetically modified organism that conveys significant productivity and income benefits while reducing the use of pesticides damaging to human and ecological health.

RICE-FISH FARMING SYSTEM IN LAMONGAN, EAST JAVA, INDONESIA: SWOT AND PROFIT EFFICIENCY ANALYSIS

The agricultural sector needs to make breakthroughs in the design of production systems to improve farmers' income and operation efficiency. One of the ways is to redesign rice production methods by applying a rice-fish farming system. Lamongan has a different system that combines rice cultivation with vannamei shrimp. Due to the limitation of farmers, the efficiency of the system has not yet reached the optimal level. This study describes the rice-fish farming system, identifies the SWOT and generated the grand strategy matrix, and analyzed the profit efficiency using Stochastic Frontier Analysis. The results showed that the strengths and opportunities are more influential, where the position was in the quadrant I; which means it is in a good strategic position. Meanwhile, the input factors which significantly influence profit where the cost of paddy seed, the cost of organic fertilizer, the cost of inorganic fertilizer, the cost of pesticide, and the cost of shrimp feed. The profit efficiency analysis shows that respondents engaged in this system did not efficiently allocate inputs and production cost factors appropriately. The average profit efficiency level was 78.05 percent; it means that there were still opportunities to increase profits from the system by 21.5 percent.
