Abstract
A field experiment was conducted during the rainy (kharif) seasons of 2020 and 2021 at the Research Farm of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh, to evaluate integrated nutrient management in transplanted basmati rice. Ten treatments comprising graded levels of the recommended dose of NPK fertiliser, pressmud, vermicompost, and NPK-solubilising microbial consortia were evaluated in a split-plot design with three replications. Plant height, tiller number, dry matter accumulation, yield attributes, grain and straw yields, biological yield, and harvest index were recorded. The application of 125% of the recommended NPK dose produced the highest plant height at harvest (116.2 cm), number of tillers at harvest (262 m⁻²), dry matter accumulation at harvest (1,101.4 g m⁻²), panicle length (26.5 cm), filled grains per panicle (84), grain yield (46.1 q ha⁻¹), straw yield (63.8 q ha⁻¹), biological yield (109.9 q ha⁻¹), and harvest index (41.9%). The control recorded the lowest grain yield (22.4 q ha⁻¹) and biological yield (69.8 q ha⁻¹). However, 75% NPK + pressmud at 1.5 t ha⁻¹ + NPK consortia and 100% NPK + NPK consortia produced statistically comparable values to 125% NPK for most growth and yield parameters. These findings indicate that combining mineral fertiliser with organic and microbial inputs can maintain competitive crop performance while reducing reliance on fertiliser application above the recommended dose.
A field experiment was conducted at the AICRP on Management of Saline Water and Associated Salinization in Agriculture, RVSKVV, College of Agriculture, Indore, at Salinity Research Farm, Baphalgaon, Barwaha, District Khargone (M.P.), to evaluate the effects of gypsum and Gliricidia sepium green leaf biomass on the growth and yield of wheat under sodic Vertisols. The experiment was laid out in a split-plot design with three replications and comprised three levels of gypsum requirement (0, 50 and 75% GR) and three levels of Gliricidia biomass (0, 5 and 10 t ha-1). The results showed that increasing levels of gypsum and Gliricidia significantly improved plant population, plant height, number of tillers, dry matter accumulation, yield attributes, and wheat yield. The 75% GR treatment recorded the highest plant population (130.0 m-2), plant height at harvest (89.1 cm), tillers per plant (6.60), dry matter accumulation (22.73 g plant-1), grain spikes (19.8 plant-1), test weight (24.02 g), grain yield (3878.3 kg ha-1), straw yield (5150.0 kg ha-1), and biological yield (9028.3 kg ha-1). Similarly, the application of 10 t ha-1 Gliricidia produced superior growth and yield parameters. The combined use of gypsum and Gliricidia was effective in improving wheat productivity under sodic soil conditions. The study indicates that the integrated application of 75% gypsum requirement together with 10 t ha-1 Gliricidia biomass is a promising strategy for sustainable wheat production in sodic Vertisols of the Nimar Valley.

A field experiment was carried out during the Kharif season of 2022 at the Research Farm of the Department of Agronomy, JNKVV, Jabalpur (M.P.), to evaluate the effects of Nutripearls, an organic acid-based granular fertiliser, on the yield components and productivity of transplanted rice (Oryza sativa L., cv. JR 206). The trial was laid out in a Randomised Block Design (RBD) with nine treatment combinations involving graded levels of the Recommended Dose of Fertilisers (RDF) and Nutripearls applied at the tillering and panicle initiation (PI) stages. The results demonstrated significant variations among treatments in yield attributes and overall productivity. Application of 100% RDF + Nutripearls @ 50 kg/ha at the tillering and PI stages (T2) recorded superior growth and yield parameters, including the maximum number of effective tillers (406.5/m2), panicle length (27.87 cm), and sound grains per panicle (196.27), along with the lowest number of sterile grains per panicle (6.47). Consequently, T2 produced the highest straw yield (7582.20 kg/ha) and harvest index (43.91%), markedly outperforming both 100% RDF alone (T8) and the untreated control (T9). Higher doses of Nutripearls (75 kg/ha and 100 kg/ha) did not offer significant improvements over the 50 kg/ha rate. Overall, integrating Nutripearls at 50 kg/ha alongside 100% RDF can enhance nutrient availability and crop partitioning efficiency, indicating its potential for maximising transplanted rice yields under the experimental conditions.

An agronomic investigation was conducted during the rabi seasons of 2023-24 and 2024-25 at the Crop Research Center of ITM University, Gwalior, Madhya Pradesh, India, to determine the influence of nutrient management and post-emergence herbicides on the yield and economic of wheat (Triticum aestivum L.). The experiment, comprising three nutrient management practices and six herbicide applications, was laid out in two factor randomized block design with three replications. The findings showed that, among the nutrient management practices, 75% RDF + vermicompost at 1.5 t ha-1 recorded the highest yield attributing characteristics, viz., number of effective shoots (393.8 and 411.1), spike length (10.7 and 11.1 cm), number of grains spike-1 (43.9 and 45.1), 1000-grain weight (41.2 and 42.3 g), grain yield (4117 and 4218 kg ha-1), and net returns (₹75,324.6 and ₹87,438.0 ha-1) during 2023-24 and 2024-25, respectively. Herbicide application significantly influenced weed control efficiency and yield. The weed-free treatment recorded 100% weed control efficiency and the highest grain yields (4530 and 4661 kg ha-1 during 2023-24 and 2024-25, respectively). Among the herbicidal treatments, sulfosulfuron + metsulfuron-methyl was the most effective, recording the highest weed control efficiency (83.34 and 84.77%), yield attributing characteristics, grain yield (4344 and 4468 kg ha-1) and net returns (₹82,251.1 and ₹95,405.7 ha-1) during 2023-24 and 2024-25, respectively. Therefore, applying 75% RDF + vermicompost at 1.5 t ha-1 together with sulfosulfuron + metsulfuron-methyl resulted in higher productivity and net returns in wheat production.

A field experiment was conducted during the kharif seasons of 2024 and 2025 at the Experimental Farm, Department of Agronomy, School of Agricultural Sciences, Hapur, Uttar Pradesh, to evaluate the effects of different nitrogen and silicon levels on the yield attributes and yield of rice (Oryza sativa L.). The experiment was laid out in a Randomised Block Design with three replications and comprised nine treatment combinations involving the recommended dose of fertilisers (RDF) and varying levels of silicon applied through broadcasting and foliar application. The results showed that silicon application significantly influenced the yield attributes and yield of rice. Among the treatments, RDF combined with 120 kg Si ha⁻¹ through broadcasting (T₅) recorded the highest number of panicles (286.78 m⁻²), panicle length (26.08 cm), grains per panicle (83.06), and test weight (26.18 g). The same treatment also produced the maximum grain yield (5365.44 kg ha⁻¹), straw yield (7759.62 kg ha⁻¹), and harvest index (42.76%), which were significantly superior to the other treatments. The improvement in yield and yield attributes may be attributed to enhanced nutrient uptake, increased photosynthetic efficiency, better grain filling, and improved assimilate translocation under silicon application. The study indicated that the combined application of RDF and 120 kg Si ha⁻¹ through broadcasting is an effective nutrient management strategy for maximising rice productivity under the agro-climatic conditions of western Uttar Pradesh.

A field experiment was conducted during the rabi seasons of 2024–25 and 2025–26 at the Experimental Farm, School of Agricultural Sciences and Technology, RIMT University, Mandi Gobindgarh, Punjab, India, to evaluate the effects of inorganic fertilisers, organic manures, zinc sulphate (ZnSO₄), and Azotobacter on the growth, yield, and economics of wheat (Triticum aestivum L.). The experiment was laid out in a Randomised Block Design (RBD) comprising twelve treatments with three replications. The treatments consisted of different combinations of the recommended dose of fertilisers (RDF), farmyard manure (FYM), vermicompost, poultry manure, ZnSO₄, and Azotobacter. The results revealed that integrated nutrient management significantly (P ≤ 0.05) improved plant height, leaf area index, tiller density, dry matter accumulation, grain yield, straw yield, harvest index, and economic returns compared with the control. Among the treatments, 75% RDF + 1.25 t ha⁻¹ vermicompost + 20 kg ZnSO₄ ha⁻¹ + 5 kg Azotobacter ha⁻¹ (T₁₁) recorded the highest grain yield of 4856.40 kg ha⁻¹ and 4912.00 kg ha⁻¹ during 2024–25 and 2025–26, respectively. The same treatment also produced the highest net returns of ₹70,493 ha⁻¹ and ₹72,546 ha⁻¹ during the respective years. These findings indicate that the integrated application of 75% RDF, vermicompost, ZnSO₄, and Azotobacter can effectively enhance wheat productivity and profitability while reducing dependence on chemical fertilisers under the agro-climatic conditions of Punjab, India.

A field experiment was conducted during the rabi season of 2025–26 at SRM College of Agricultural Sciences, Tamil Nadu, India, to study the effects of crop geometry and nutrient management practices for transplanted finger millet in irrigated conditions. The experiment was laid out in a split plot design with 3 replications. The finger millet variety ATL-1 was transplanted at 21 days after sowing (DAS). Growth, physiological, yield attributes and yield parameters were recorded during the crop period. Among the treatments, 30 × 10 cm spacing combined with split application of 50 % recommended dose of fertilisers (RDF) at basal + 25 % at active tillering + 25 % at flowering recorded superior growth and physiological performance, including higher plant height, dry matter production, tiller count, leaf area index and chlorophyll content. The same treatment also produced higher yield attributes and recorded maximum grain yield (1415 kg ha-1), straw yield (4330 kg ha-1). The study indicated that optimum crop geometry combined with split nutrient application enhanced growth, physiological efficiency and yield of transplanted finger millet under irrigated conditions. The heatmap analysis based on normalised values further confirmed that the M1S3 treatment exhibited the best overall performance across all observed growth, yield attributes and yield parameters.
