Abstract
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.
Okra is an economically important vegetable crop with high nutritional value, widely cultivated in tropical and subtropical regions globally. An experiment was conducted to assess the effect of eight treatments on the growth, yield, and economic performance of okra (Abelmoschus esculentus (L.) Moench) under irrigated conditions in the Kilinochchi District, Sri Lanka, during September to November 2023. The experiment was conducted in a Randomized Complete Block Design (RCBD) with three replicates. Eight treatments (T1–T8) consisting of different organic manure applications, and the Department of Agriculture (DOA)-recommended chemical fertilizers were applied, including a control treatment without organic manure. Haritha okra was used as the test variety. Growth parameters including plant height, dry weight, and number of leaves, and yield parameters including number of pods per plant, fresh pod weight, and shelf life were evaluated. Poultry manure applied at 460 g plant⁻¹ (T2) recorded the highest plant height (31.4 cm), number of leaves (8.0 leaves plant⁻¹), dry pod weight (13.3 g plant⁻¹), fresh pod weight (130 g plant⁻¹), number of pods per plant (8 pods), and shelf life (5.7 days). Compared with the control treatment (T1), poultry manure increased plant height by 35.3%, fresh pod weight by 160%, and shelf life by 32.6%. No significant difference (p ≤ 0.05) was observed between T2 and T5 (cattle manure: poultry manure, 230 g: 230 g plant⁻¹). The highest benefit-cost ratio was recorded in T2 and T5. It can be concluded that poultry manure at 460 g plant⁻¹ was the most effective treatment for improving the growth, yield, and economic performance of okra under irrigated conditions.

The declining productivity of rice and deterioration of soil health associated with conventional rice cultivation necessitate the adoption of sustainable nutrient management strategies. Field experiments were conducted during the Kharif seasons of 2021–22 and 2022–23 at the Students’ Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, to evaluate the effects of organic manure, inorganic fertilisers and bio-inoculants on the growth of rice (Oryza sativa L.). The experiment comprised 18 treatment combinations arranged in a randomised block design with 3 replications, involving different combinations of inorganic fertilisers, organic manures and biofertilisers. The results indicated that among the various growth parameters, the maximum plant height (99.15 cm and 99.85 cm), number of tillers (409.4 m-2 and 412.25 m-2), dry matter accumulation (760.48 g m-2 and 764.34 g m-2) and leaf area index (4.32 and 4.37) were recorded during 2021–22 and 2022–23, respectively, under treatment T17 (100 % NPK + 5 t ha-1 FYM + Azolla 300 kg ha-1 + S 30 kg ha-1 + Zn 5 kg ha-1). These findings highlight the synergistic effects of integrating organic and inorganic nutrient sources along with bio-inoculants. This integrated approach enhances crop performance, improves soil sustainability and ensures better economic returns, making it a promising strategy for modern rice farming systems.

The sustainable management of soil fertility is essential for improving common bean (Phaseolus vulgaris L.) productivity under the semi-arid conditions of Afghanistan. This study evaluated the comparative effects of two organic fertilizers, inorganic fertilizer (NPK), and their integrated application on the growth and yield performance of common bean during the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University. The experiment was arranged in a Randomized Complete Block Design (RCBD) with six fertilizer treatments and three replications. Growth traits, yield components, grain yield, biological yield, and harvest index were analyzed using analysis of variance (ANOVA), and treatment means were separated by Tukey’s HSD test at the 5% probability level. Fertilizer treatments significantly influenced most growth and yield parameters. The integrated application of 50% OF-1 + 50% NPK (T5) consistently produced superior plant growth, increased yield components, and achieved the highest grain yield, biological yield, and harvest index compared with the sole application of organic or inorganic fertilizers and the unfertilized control. The improved performance of the integrated treatment was attributed to enhanced nutrient availability and more efficient nutrient utilization throughout the crop growth period. These findings demonstrate that integrated nutrient management is a sustainable and effective strategy for increasing common bean productivity under semi-arid agroecological conditions. Future studies should evaluate long-term effects of integrated nutrient management under diverse agroecological conditions.

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.

The increasing demand for livestock-derived products and the growing emphasis on sustainable agricultural production necessitate the development of efficient organic nutrient management strategies for fodder-based cropping systems.
A two-year field experiment was conducted at the ICAR–National Dairy Research Institute, Karnal, located in the Trans-Gangetic Plains of India, to evaluate the integrated effects of farmyard manure (FYM), plant biostimulants (
Panchagavya
and seaweed extract), and bioinoculants on the growth, yield, chlorophyll content, and energy fractions of fodder maize (
Zea mays
L.) and berseem (
Trifolium alexandrinum
L.). The experiment was laid out in a randomized complete block design with six treatments and six replications.
Among the treatments, T
3
(PGPR + 75% recommended dose of nitrogen (RDN) through FYM + three foliar sprays of
Panchagavya
) consistently produced the highest growth, fodder yield, chlorophyll concentration, and energy fractions in both crops during the two experimental years. In fodder maize, T
3
recorded the maximum green fodder yield (32.4–34.7 t ha
-
¹) and dry fodder yield (7.4–8.1 t ha
-
¹). Similarly, in berseem, T
3
produced the highest total green fodder yield (57.0–58.5 t ha
-
¹) and dry fodder yield (7.6–8.1 t ha
-
¹), over the absolute control. Total chlorophyll content reached 2.39–2.43 mg g
-
¹ in maize and 2.29–2.32 mg g
-
¹ in berseem under T
3
, accompanied by significant improvements in digestible energy, metabolizable energy, digestible feed energy, and net energy. The PGPR + 75% RDN through FYM + seaweed extract treatment (T
4
) also produced significant improvements over the absolute control and ranked among the best-performing treatments across most measured parameters, demonstrating the potential of seaweed extract as an effective biostimulant in integrated nutrient management.
Overall, the findings demonstrate that integrating PGPR with 75% RDN through FYM and
Panchagavya
was the most effective strategy for enhancing fodder productivity, nutritive quality, and energy value, while the PGPR + 75% RDN through FYM + seaweed extract treatment also provided substantial benefits and represents a promising alternative biostimulant-based approach for sustainable maize–berseem fodder production systems.

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
