Abstract
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.
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 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.

Although nutrient management plays a crucial role in determining the productivity of barley (Hordeum vulgare L.), comparative information on the effectiveness of organic and inorganic nutrient sources under local conditions is still scarce. A field experiment was conducted during the 2024, Rabi season at Khairahani, Chitwan, to evaluate the effects of different nutrient sources on growth, yield, and profitability of barley var. Mustangey Jau. Using a randomized complete block design with five treatments-controls, chemical fertilizer NPK, poultry manure, farmyard manure, and vermicompost-each replicated four times, significant differences were observed in plant height, leaf area index, effective tillers, and grain yield. NPK fertilizer produced the highest plant height (94.80 cm), leaf area index (0.18), effective tillers (6.52), and grain yield (1.69 t/ha), followed by poultry manure and vermicompost. Organic sources improved growth over the control but yielded less than NPK. Economic analysis showed NPK achieved the highest net return and benefit-cost ratio (2.19), followed by poultry manure (1.34). Therefore, the application of recommended NPK fertilizer is suggested for maximizing barley yield and profitability, while poultry manure can be considered as a suitable organic alternative for improving productivity compared with other organic sources.

A field experiment was conducted during Kharif 2022 and 2023 at Dr. BRC Agricultural Research Station (ARS), Mandor, Rajasthan, to evaluate the effect of biofertilisers and growth-promoting microorganisms on growth, yield, and profitability of mungbean (Vigna radiata (L.) Wilczek, var. GM-4) under the mungbean–wheat cropping system. The experiment was laid out in a Randomised Block Design with ten treatments and three replications. Treatments consisted of different combinations of the recommended dose of fertilisers and seed inoculation, soil application, or combined seed and soil application of Rhizobium and phosphate-solubilising bacteria (PSB). The results indicated that growth parameters, yield attributes, grain yield, biological yield, and economic returns were significantly influenced by the treatments. The greatest numerical plant heights at 30 DAS (46.8 cm) and 45 DAS (55.9 cm) were recorded under T₁₀, while T₅ recorded comparable values of 45.8 and 55.3 cm, respectively. The highest numbers of pods per plant (39.6) and seeds per pod (13.5), dry matter production (3.50 t ha⁻¹), and test weight (48.1 g) were observed under T₅, whereas the highest numerical chlorophyll content (4.00 mg g⁻¹) was recorded under T₁₀. The highest grain yield (pooled: 1458 kg ha⁻¹) and net return (₹98,855 ha⁻¹) were recorded with 100% RDF (T₅), whereas 75% RDF combined with seed and soil application of Rhizobium + PSB (T₁₀) produced a pooled grain yield of 1400 kg ha⁻¹ and a B:C ratio of 4.41, remaining statistically at par with T₅. Thus, integrated use of biofertilisers with 75% RDF can reduce fertiliser requirement without significant yield loss and improve profitability.

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.

Chickpea (Cicer arietinum L.) is an important pulse crop valued for its nutritional quality and role in sustainable agriculture. However, productivity is often constrained by low soil fertility and poor nutrient management, particularly phosphorus deficiency. A field experiment was conducted during the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University, Afghanistan, to evaluate the effect of different levels of diammonium phosphate (DAP) fertilizer on growth and yield of chickpea variety Flip 94. The experiment was arranged in a Randomized Complete Block Design (RCBD) with five DAP levels (0, 50, 100, 150, and 200 kg ha⁻¹) and three replications. Results showed that DAP application significantly influenced all growth and yield parameters, while replication effects were non-significant. Treatment 3 (100 kg ha⁻¹ DAP) consistently performed best, recording the highest plant height (34.23 cm), number of branches per plant (4.92), number of pods per plant (37.47), grains per pod (1.93), and grain yield (5.52 t ha⁻¹). In contrast, the control treatment recorded the lowest values for all studied traits. The improved performance under optimal DAP application is attributed to enhanced nutrient availability, better root development, increased nodulation, and improved photosynthetic efficiency, which collectively supported stronger vegetative growth and reproductive development. In conclusion, application of DAP fertilizer significantly improves chickpea growth and yield under Kabul agro-climatic conditions. Treatment 3 (100 kg ha⁻¹ DAP) was identified as the most effective dose for maximizing productivity of chickpea variety Flip 94.
