Abstract
Integrated nutrient management, which combines organic and inorganic nutrient sources, is an important strategy for improving soil fertility and nutrient utilisation in sustainable agriculture. Effective nutrient management is particularly important for optimising wheat growth and yield. This study investigated the effects of farmyard manure (FYM), NPK consortia, and nano-urea, in combination with different proportions of the recommended dose of fertiliser (RDF), on wheat growth, yield, and nitrogen-use efficiency. The field experiment was conducted at KVK, Ghazipur, using a randomised block design with three replications. Nine treatments comprising different combinations of RDF, FYM, NPK consortia, and nano-urea were evaluated. Plant height, tiller density, grain and straw yields, and agronomic use efficiency (AUE) were measured at critical growth stages or at harvest. Data were analysed using analysis of variance, and treatment means were compared using the critical difference at the 5% probability level. Nutrient management significantly affected plant height, and T4 (100% RDF + FYM) produced the greatest height at all stages, reaching 87.8 cm at harvest. T4 also recorded the highest tiller density at 60 DAS (106.8 m⁻¹ row length) and harvest (69.8 m⁻¹ row length), grain yield (6.20 t/ha), straw yield (7.60 t/ha), and AUE (17.5 kg grain/kg N). T6 produced the second-highest grain yield (5.72 t/ha), while T7 outperformed T2. Overall, combining 100% RDF with FYM improved wheat growth, yield, and nitrogen-use efficiency.
Sustainable agriculture, particularly efficient nitrogen management, is essential for maintaining soil fertility, improving crop quality, and reducing the environmental footprint of agricultural production. This study evaluated the effects of reduced soil-applied nitrogen and foliar application of the nitrogen–sulfur fertilizer Nitron-S on the quality of silage maize (Zea mays L.). A field experiment was conducted using a single-factor design with four fertilization treatments differing in nitrogen supply and foliar fertilization intensity. The silage maize cultivar Farmmortiz was grown under uniform manure application (30 t ha−1) applied in autumn. The control treatment received the full soil-applied nitrogen rate, whereas experimental treatments received 50% of the conventional nitrogen dose supplemented with foliar Nitron-S at doses of 20, 40, and 60 dm3 ha-1, applied twice during the growing season. After harvest, plant yield and selected quality parameters were determined, including dry matter, crude protein, sugars, starch, ash, neutral detergent fiber (NDF), acid detergent lignin (ADL), ammonia fraction, and organic matter digestibility (VOS). Fertilization treatments significantly affected most quality traits. The highest Nitron-S rate increased starch concentration (up to approximately 30% under N4) but also elevated ADL content (by about 25%) and slightly reduced VOS (only by about 1–3%. Partial replacement of soil-applied nitrogen with foliar nitrogen–sulfur fertilization improved the nutritional quality of maize silage and reduced nitrogen input. This approach may contribute to more sustainable maize production.

Wheat productivity is constrained by declining soil fertility and low nutrient-use efficiency resulting from the continuous dependence on chemical fertilizers. Integrated Nutrient Management, through the judicious integration of organic, inorganic, and biological nutrient sources, offers a sustainable approach to enhance crop growth, yield, soil health, and long-term productivity; however, its effectiveness in combination with nano-fertilizers requires further evaluation. Therefore, a field experiment was planned during the Rabi season of 2024-25 and 2025-26, at the research farm of Maharishi Markandeshwar (Deemed to be University), Mullana. The experiment was laid out in a two-factorial randomized block design with three replications. Factor A comprised two wheat varieties (WH 1270 and DBW 222), while Factor B consisted of eight nutrient management treatments involving RDF, vermicompost (2 t/ha), foliar nano urea (1250 mL/ha), foliar nano DAP (1250 mL/ha), and Azotobacter applied alone or in combination. The pooled data revealed that the variety DBW 222 showed significantly higher plant height (94.34 cm), number of tillers/meter row length (65.77), DMA/meter row length (224.82 g), LAI (5.56), spike length (9.84 cm), grains/spikes (48.31), effective tillers/m2 (300.80), test weight (40.27 g), grain yield (5042 kg/ha) and straw yield (6651 kg/ha) over variety WH 1270. Among various nutrient combinations, maximum plant height (104.65 cm), number of tillers/meter row length (70.51), DMA/meter row length (251.73 g), LAI (6.18), spike length (10.88 cm), grains/spikes (51.37), effective tillers/m2 (322.57), test weight (42.21 g), grain yield (5642 kg/ha) and straw yield (7439 kg/ha) was recorded with treatment T3 (100% RDF with vermicompost @ 2t/ha) which was found at par with T5 and T4. These treatments were found superior over T2, T6, T8 and T7. The least were found in T1

Aims: The study aims to compare the effects of different nutrient management strategies on maize productivity, nutrient uptake, soil fertility and profitability in Alfisols.
Study Design: The field experiment was conducted in a randomised block design with seven nutrient management treatments and three replications.
Place and Duration of Study: Agricultural Research Station, Tornala, Professor Jayashankar Telangana Agricultural University, Siddipet district, Telangana, India, during Kharif 2019.
Methodology: Maize hybrid DHM-117 was grown under seven nutrient management treatments: the recommended dose of fertiliser with farmyard manure, soil-test-based fertilisation, farmers’ practice, organic farming, integrated nutrient management, natural farming and an unfertilised control. Growth parameters, yield attributes, grain and stover yields, soil pH, electrical conductivity, organic carbon, available nitrogen, phosphorus and potassium, plant nutrient concentrations, nutrient uptake and economic returns were recorded and analysed using analysis of variance.
Results: Integrated nutrient management produced the highest grain yield (6963 kg ha⁻¹) and stover yield (8945 kg ha⁻¹), together with superior cob weight, grain weight per cob and 100-grain weight compared with the other treatments. It also recorded the highest soil organic carbon (0.63%), available phosphorus (25.91 kg ha⁻¹), and total uptake of nitrogen, phosphorus and potassium (196.6, 45.5 and 150.9 kg ha⁻¹, respectively), and achieved the highest benefit–cost ratio (2.00). Soil-test-based fertilisation showed comparable yield performance and favourable nutrient status, whereas organic and natural farming improved selected soil-quality indicators but resulted in lower yields and benefit–cost ratios during the study period.
Conclusion: Under the conditions of this study, integrated nutrient management was the most effective and balanced strategy for enhancing maize yield, nutrient uptake, soil fertility and profitability in Alfisols, while soil-test-based fertilisation emerged as a viable alternative.

Wheat productivity is strongly influenced by nutrient availability and weed competition, both of which affect crop growth, nutrient acquisition, and yield formation. Integrating mineral fertilisers with farmyard manure may improve nutrient availability and utilisation, while effective weed management can reduce competition for essential resources. However, the combined effects of contrasting fertility regimes and weed-management practices on wheat productivity and nutrient acquisition require further evaluation. A field experiment was conducted during the rabi season of 2019–20 to evaluate the effects of integrated fertility and weed management on wheat productivity and nutrient acquisition. The experiment used a 4 × 4 factorial randomised block design with three replications, comprising four fertility regimes and four weed-management practices. Among the fertility treatments, 125% RDF-IF with 25% of the nutrient requirement supplied through farmyard manure (FYM) produced the highest grain yield (47.97 q ha⁻¹), straw yield (71.05 q ha⁻¹), and biological yield (119.01 q ha⁻¹). This treatment also recorded the highest grain N, P, and K uptake of 119.98, 23.15, and 120.48 kg ha⁻¹, respectively. Weed management markedly influenced crop performance. Maintaining the crop weed-free up to 60 days resulted in the highest grain yield (51.28 q ha⁻¹), straw yield (75.54 q ha⁻¹), and biological yield (126.81 q ha⁻¹), together with grain N, P, and K uptake of 127.00, 25.38, and 130.22 kg ha⁻¹, respectively. Nutrient concentrations in grain and straw varied comparatively little across fertility treatments, indicating that the greater nutrient uptake was mainly associated with increased biomass production. Overall, the findings show that combining mineral nutrient supply with FYM and effectively suppressing early-season weed competition can improve wheat productivity and nutrient acquisition under the conditions of this experiment.

Background: A field study was conducted to evaluate integrated nutrient management practices involving organic, inorganic, microbial and nano-fertilizer approaches for improving growth, yield, phosphorus uptake, economics and soil biological properties of mung bean varieties. Methods: Two mung bean varieties, Pusa-1431 and Virat, were tested under six nutrient management treatments in a factorial randomized block design during the Kharif season. Observations on growth, yield, phosphorus uptake, economics and soil biological activity were analyzed using ANOVA. Result: Pusa-1431 performed better than Virat in growth, yield, phosphorus uptake and soil biological activity. The treatment comprising 75% NPK + FYM @ 5 t ha-1 + NPK consortia + Nano-P spray at 25 DAS produced the highest grain yield (12.4 q ha-1), benefit:cost ratio (2.35), phosphorus uptake and soil microbial activity, indicating that integrated nutrient management enhanced productivity, nutrient-use efficiency and soil health compared to sole chemical fertilization.

A significant issue in the wheat production systems is the need to increase the efficiency of nutrient use without compromising soil health. This paper has examined the synergistic impact of organic manures, Nano-DAP on growth, yield and soil fertility of wheat (Triticum aestivum L.) under field conditions during the Rabi seasons of 2023-24 and 2024-25 in Lucknow, India. The treatments were: green manure, farmyard manure and vermicomposting (5 t ha-1), with various nutrient management strategies based on Nano-DAP. The findings indicated that vermicompost was highly beneficial in promoting crop growth, with the highest values in terms of plant height, density and biomass growth. Nano-DAP seed treatment and foliar sprays, combined with 100% NPK, created the greatest grain yield (49.64 q ha-1) and better yield characteristics than traditional fertilization. It was also seen that the combined application enhanced the uptake of nutrients and the soil fertility status.In general, the results imply that the combination of organic Manures and NanoDAP is an efficient and sustainable approach to nutrient management to achieve better wheat yields and better soil health.
