Effect of integrated use of organic and inorganic sources of nutrients on growth and yield of black gram (Vigna mungo (L.) Hepper)

The present research study aimed to evaluate the combined influence of inorganic and organic nutrient sources on the growth and yield parameters of black gram (Vigna mungo (L.) Hepper). The result indicated that using a combination of 50% of the recommended dose of fertilizer and 50% vermicompost had a significant positive impact on growth attributes, yield parameters, and biochemical parameters. These findings suggests that the simultaneous application of organic and inorganic fertilizers can effectively improve soil fertility and crop yield. Notably, integrating 50% of the recommended fertilizer dose with 50% vermicompost proved to be particularly beneficial in enhancing both the growth and yield of black gram compared to other treatments, including the control group.

Unveiling the Implications of Organic Nutrient Management Protocols on Soil Properties, Economic Sustainability, and Yield Optimization in Fenugreek Cultivation in Acidic Soils of Northeast India

Utilizing yield, profitability, and environmental sustainability in terms of soil quality as the goal variables, we created a methodological protocol for a thorough assessment of nutrient management (NM) technologies for feasibility and optimized fenugreek production employing organic sources of nutrients in the acid soil of Northeast India. Five organic nutrient management technologies were tried and tested comprising T1: absolute control; T2: 2.5 t ha−1 vermicompost (VC) + 250 kg ha−1 lime; T3: 5 t ha−1 farmyard manure (FYM) + 250 kg ha−1 lime; T4: 10 t ha−1 FYM + 250 kg ha−1 lime; and T5: 5 t ha−1 VC + 250 kg ha−1 lime with four replications laid out in a randomized block design for two consecutive growing seasons during 2018–2020. Results indicated that across the differential levels of organic amendments (treatments) employed, the addition of maximum doses of VC and FYM, in general, excelled over the other treatments concerning fenugreek seed yield, its yield attributes, soil properties, and better economic returns. Thus, the overall findings elucidated that the addition of higher doses of organic amendments (VC and FYM) can sustainably improve fenugreek productivity, soil properties, and economic returns for fenugreek growers in the acid soil of Northeast India.

Contribution of Litter and Root to Soil Nutrients in Different Rocky Desertification Grasslands in a Karst Area.

Litter and root decomposition is an important source of soil organic matter and nutrients. To ascertain the contribution of litter and root to natural grassland nutrients in rocky desertification areas, from March 2017 to January 2018, the continuous soil column method, collector method, and litter decomposition method were used to study the soil nutrients, litter and root biomass, decomposition, and nutrient release of potential, moderate, and severe rocky desertification grasslands, as well as their responses to rocky desertification. The results showed that the litter and root decomposition rate showed a trend of being first fast and then slow, and the decomposition rate of litter and root was greater than 50% after 300 days. The annual litter decomposition rates of potential, moderate, and severe rocky desertification grasslands were 69.98%, 62.14%, and 49.79%, respectively, and the annual decomposition rates of root were 73.64%, 67.61%, and 64.09%, respectively. With a deepening degree of rocky desertification, the litter and root decomposition rate decreased. The decomposition coefficients, k, of litter in potential, moderate, and severe rocky desertification grasslands were 1.128, 0.896, and 0.668, respectively, and the decomposition coefficients, k, of root were 1.152, 1.018, and 0.987, respectively. The nutrient release processes of litter and root were different, and the release mode ultimately manifests as "release". In rocky desertification grasslands, the organic carbon (OC), total nitrogen (TN), total phosphorus (TP), and total potassium (TK) released by litter and root decomposition were 18.93-263.03 g·m-2·yr-1, 1.79-5.59 g·m-2·yr-1, 0.18-0.47 g·m-2·yr-1, and 0.66-3.70 g·m-2·yr-1, respectively. The contribution of root to soil nutrients was greater than that of litter. The degree of rocky desertification was negatively correlated with the biomass, decomposition rate, and nutrient return amount of litter and root. The results of this study provide direct field evidence and illustrate the contribution of litter and root decomposition in rocky desertification grasslands to soil nutrients.

Chemical composition and egg production capacity throughout bloom development of ctenophore Mnemiopsis leidyi in the northern Adriatic Sea.

High abundances of gelatinous zooplankton (GZ) can significantly impact marine ecosystem by acting as both sink and source of organic matter (OM) and nutrients. The decay of GZ bloom can introduce significant amount of OM to the ocean interior, with its variability influenced by GZ life traits and environmental factors, impacting microbial communities vital to marine biogeochemical cycles. The invasive ctenophores Mnemiopsis leidyi has formed massive blooms in the northern Adriatic Sea since 2016. However, the variability in the chemical composition and egg production of blooming populations, as well as the role of environmental factors in governing this variability, remains largely unknown. Our analysis of biometry, chemical composition, and fecundity of M. leidyi sampled in the Gulf of Trieste in 2021 revealed stable carbon and nitrogen content throughout bloom development, with no significant correlation with seawater temperature, salinity, oxygen, and chlorophyll a concentration. Although the studied population exhibited homogeneity in terms of biometry and chemical composition, the number of produced eggs varied substantially, showing no clear correlation with environmental variables and being somewhat lower than previously reported for the study area and other Mediterranean areas. We observed a positive correlation between the wet weight of individuals and the percentage of hatched eggs, as well as a significant positive correlation between the percentage of hatched eggs and ambient seawater temperature. Additionally, we noted that the speed of hatching decreased with decreasing seawater temperature in autumn, corresponding to the end of M. leidyi bloom.

Downed woody debris varies with climate and harvesting treatment in Douglas-fir forests of British Columbia, Canada

Downed woody debris is important for biodiversity, forest regeneration, and carbon, nutrient, and water cycling, and past studies have examined how the coarse fraction is affected by climate or harvesting. In a field study in Douglas-fir dominated forests, we expand existing knowledge by investigating the interacting effects of climate and harvesting on downed woody debris of all sizes. Across a 900-km long latitudinal gradient in British Columbia, we found that coarse woody debris (CWD, >7.5 cm diameter) in humid climates contained 700% greater carbon stocks, had 500% greater volume, and was more diverse than in arid climates. Pre- and post-harvest, small and fine woody debris comprised a higher proportion of total woody debris carbon stocks in arid than moist climates, especially after clearcutting and seed tree treatments. Harvesting generally decreased total CWD volume, but it was not depleted on any site. Harvesting substantially reduced the volume of large, highly decomposed CWD except at the two most arid sites, and losses of large CWD increased with increasing tree removal. These losses were accompanied by a pulse of fresh, small diameter CWD and SWD which are short-term organic nutrient sources but have less habitat value than larger pieces and contribute to fuel loads. Because CWD was less abundant in arid than humid mature forests, care must be taken on arid sites to avoid its depletion during harvesting, especially clearcutting, where future woody debris inputs will not occur for decades.

Application of different organic amendments influences the different forms of sulphur in the soil of pea – onion – cauliflower cropping system

A study was conducted in sandy clay loam soils in a subtropical zone of Bihar to evaluate the effect of frequent application of organic amendments on sulphur fractions. Different organic amendments, including farmyard manure (FYM), vermicompost, azotobacter, phosphate solubilizing bacteria (PSB), panchagawya, and neem cake, were applied through nine treatments that resulted in a significant increase of water-soluble S, available S, heat-soluble S, adsorbed S, and organic S in organic treatment compared to the recommended dose of fertilizer (RDF) and control treatment. The maximum increment was observed in the treatment where the recommended dose of nitrogen was replaced by 75% recommended dose of nitrogen substituted farmyard manure + 25% recommended dose of nitrogen (vermicompost) along with azotobacter + PSB + one foliar spray of panchagawya. The total S content varied widely from 382 to 736 mg kg-1. Increment in all the forms of sulphur is observed as a result of the application of different organic nutrient sources. All the forms of sulphur share a mutual positive and significant correlation with each other. Regression analysis suggested that the availability of sulphur was dominated by organic sulphur, which alone can explain 97.8% of the variation in availability of available sulphur in soil.

Optimizing Growth and Yield in Aerobic Rice through IoT-based Drip Irrigation and Fertigation

Aim: A field experiment was conducted to study the effect of different IoT based drip irrigation and fertigation management practices on growth and yield of aerobic rice. Study Design: The experiment was laid out in a strip plot design with 4 main plots (Horizontal) and 3 sub-plots (Vertical) that are allocated randomly and replicated thrice. Place and Duration of Study: kharif and rabi seasons of 2022-23 & 2023-24 at ICAR-Indian Institute of Rice Research, Hyderabad. Methodology: The horizontal plot treatments were Nitrogen management practices (4) i.e., Control (N1), 100 % RDN (100% inorganic) (N2), 100 % RDN (50% inorganic & 50% organic) (N3) and 125 % RDN (100 % inorganic) (N4). Vertical plots treatments were Irrigation management practices (3) which include Saturation (I1), 10 % DASM (I2) and 20 % DASM (I3). Organic nutrient sources were given as soil application and the inorganic sources were applied through fertigation. Sensor based (IoT) irrigation scheduling was done. Results: Nitrogen application of 125% RDN with 100% inorganic consistently resulted in higher growth parameters (plant height (110.4 cm and 93.9 cm), number of tillers m-2 (392.2 and 291.8) and plant dry weight (11814.8 kg ha-1 and 9557.0 kg ha-1) during kharif & rabi respectively) followed by 100% RDN (100% inorganic) and 100% RDN (50% inorganic & 50% organic) in pooled data. Saturation irrigation resulted in taller plants with greater growth parameters (plant height (109.8 cm and 91.0 cm), number of tillers m-2 (412.3 and 283.6) and plant dry weight (10916.0 kg ha-1 and 9463.4 kg ha-1) during kharif & rabi respectively) compared to deficit irrigation treatments. Treatment of 125% RDN with 100% inorganic resulted in the higher yield attributes (no. of panicles m-2 (154.3 and 141.1), no. of filled grains panicle-1 (142.3 and 124.0), panicle weight (3.1 g and 3.3 g) during kharif & rabi respectively) and yield (4790.2 kg ha-1 and 4583.8 kg ha-1) which was statistically similar with 100% RDN (100% inorganic) and 100% RDN (50% inorganic & 50% organic). Saturation expressed higher yield attributes (no. of panicles m-2 (149.5 and 139.2), no. of filled grains panicle-1 (135.0 and 121.6), panicle weight (3.0 g and 3.2 g) during kharif & rabi respectively) and yield (4554.0 kg ha-1 and 4425.5 kg ha-1) which was on par with 10% DASM. The interaction was found to be non-significant. Conclusion: Nitrogen application of 125% RDN and 100% RDN through fertigation were found to have statistically similar growth, yield parameters and yield. IoT based irrigation at 10% DASM was found to be on par with saturation treatment among all the growth, yield parameters and yield of aerobic rice.

Integrated Nutrient Management for Lentil Cultivation: Improving Soil Fertility, Nutrient Content, and Economic Returns

Context: -Overuse of chemical fertilizers reduces soil fertility, which highlights the need to switch to integrated farming practices for sustainable growth. Purpose: – A field experiment was conducted to analyse the effects of various integrated nutrient management strategies on soil fertility generally, nutrient level fluctuations in the soil, plant uptake, and nutrient content and economic consequences in lentil farming. Method: – Eight different treatments representing various nutrient sources were used in the experiment, which used a Randomized Block Design. Each treatment had three replications. Result: – The results indicated that there was no significant difference among 8 different treatments for soil pH and EC. The available nitrogen, available phosphorus and available potassium in soil and content in straw and seed were found highest in T 8 while protein content in seed was also found highest in T 8 (24.85 %) followed by T 7 (24.50 %). But the economics of cultivation indicated T 4 to be the best with the highest B:C ratio (1.96). Conclusion: – The proper and balanced usage of organic and inorganic sources of nutrient increased soil accessible nutrient pool and there was abundant of the remainder of nutrient in the soil. The impact of combined RDF, rhizobium, vermicompost and FYM may be the reason in higher nutrient content in soil, plants and quality of lentil. Implication: – The practice of integrated nutrient management strategies are for improving lentil cultivation's soil fertility, nutrient uptake, protein content, and overall economic viability.

Optimizing nutrient application and nitrogen transformation to maximize the growth and productivity of bud chip transplanted sugarcane

The judicious use of different organic and inorganic nutrient sources is of prime importance for enhancing the productivity of long-duration and nutrient-exhaustive crops, including sugarcane. We aimed to assess the impact of optimum nutrient application through integration of bio-products and inorganic fertilizers on growth, yield of sugarcane, and N availability in sugarcane plant crops raised through bud chip settlings. The fifteen treatment combinations were replicated three times in randomized block design. Results revealed that 150% of RDF + 5 t vermicompost ha−1 + 25 kg ZnSO4 + Azotobacter + phosphate solubilizing bacteria recorded the highest growth in terms of plant population, drymatter production, cane diameter, millable canes and single cane weight; cane yield (138.7 t ha−1) and net returns (Rs. 2, 62, 600 ha−1) followed by 150% RDF + 5 t vermicompost + 25 kg ZnSO4 ha−1 in sugarcane. However, maximum benefit: cost ratio was evidenced with 150% RDF alone (1.80) and lowest in RDF + 5 t vermicompost ha−1 (0.78), respectively. NO3-N, exchangeable NH4 +-N, hydrolyzable NH4 +-N were found to represent about 20.5 to 30.9, 41.5 to 73.8, 55.8 to 76.8 mg kg−1, respectively. The relative contents of these fractions were in the order: non-hydrolysable > unidentified N > amino acid N > hydrolyzable NH4 +-N > exchangeable NH4 +-N > NO3-N > hexose amine N. Thus, the integration of organic sources with NPK holds great promise to increase cane yield and N availability in soil but with 150% RDF proved to be more remunerative and economically sound for the bud chip raised sugarcane.

Organic Farming vs. Integrated Nutrient Management: A Comparative Review of Agricultural Productivity and Sustainability

In an era where sustainable agriculture is crucial for global food security and environmental preservation, organic farming and Integrated Nutrient Management (INM) have emerged as leading practices. This review paper offers a comprehensive comparison of these two approaches, focusing on their impact on agricultural productivity and sustainability. Organic farming, with its emphasis on reducing the use of chemical fertilizers, pesticides, growth hormones, and feed additives, aligns closely with the principles of sustainability. It enhances food quality, promotes soil health, and mitigates adverse environmental effects by encouraging natural recovery cycles. However, organic farming's limitations, such as lower yields and a more labour-intensive approach have prompted interest in innovative solutions that blend organic practices with modern technologies. Integrated Nutrient Management (INM) presents a compelling alternative. By combining organic, inorganic, and biological nutrient sources, INM seeks to optimize nutrient use efficiency and maintain soil health. This approach offers a flexible nutrient management strategy, balancing organic and inorganic inputs to maintain crop productivity while reducing environmental impact. Studies have shown that INM can improve soil properties, such as bulk density, porosity, and water-holding capacity, leading to enhanced crop yields and lower greenhouse gas emissions. The paper explores how INM's integrated approach not only stabilizes crop production but also supports the growth of soil microbes, providing a source of energy and organic carbon. By using a combination of specific microorganisms, organic matter, and minimal doses of inorganic fertilizers, INM can achieve a harmonious balance that reduces environmental pollution and ensures long-term soil fertility. Ultimately, this review underscores the potential of combining organic and INM practices to create a sustainable and productive agricultural system. Through a comparative analysis, the paper aims to guide researchers, policymakers, and farmers towards adopting strategies that foster agricultural sustainability without compromising productivity.
