Abstract
Integrated nutrient management may reduce reliance on conventional fertilisers while sustaining wheat productivity. A field experiment was conducted during the 2022–2023 rabi season at Banaras Hindu University, Varanasi, to evaluate combinations of recommended fertilisers, nano urea, NPK-consortia biofertiliser, and Sagarika granular and liquid formulations in an Inceptisol. Eleven treatments were arranged in a randomised block design with three replications. Plant height, tiller number, plant population, chlorophyll content, yield attributes, grain yield, straw yield, biological yield, and harvest index were assessed. Treatment effects differed significantly for the evaluated growth and yield parameters. Treatment T11, comprising 50% urea, 100% DAP and MOP, NPK-consortia biofertiliser, foliar nano urea, and Sagarika liquid, recorded the highest plant height (94.53 cm), tiller number (8.33 plant⁻¹ at 90 DAS), chlorophyll content (56.80 SPAD), ear length (12.87 cm), grains per ear (80.00), test weight (53.03 g), grain yield (45.67 q ha⁻¹), straw yield (63.67 q ha⁻¹), and biological yield (109.33 q ha⁻¹). The highest harvest index (47.58%) was recorded under T9. These findings indicate that integrating reduced soil-applied urea with mineral fertilisers, biofertiliser, foliar nano urea, and Sagarika may support wheat growth and productivity under the tested soil and climatic conditions. Multi-season and multi-location validation is required before wider recommendation.
Seaweed-derived biostimulants may complement conventional nutrient management in rice, but their performance requires evaluation under specific soil and agroclimatic conditions. A field experiment was conducted during the kharif season of 2022–2023 at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, to assess Sagarika seaweed extract in an Inceptisol. The experiment followed a randomised block design with 11 treatments and three replications. Treatments included an absolute control, the recommended dose of fertilisers (RDF), reduced soil-applied urea, an NPK biofertiliser consortium, Sagarika granules, Sagarika liquid sprays, nano urea, and selected combinations of these inputs. Plant growth was recorded at 30, 60, and 90 days after transplanting, and yield attributes, grain yield, straw yield, biological yield, and harvest index were measured. Treatment T7, comprising 100% RDF, Sagarika granules at 10 kg acre⁻¹, and two Sagarika liquid sprays at 5 mL L⁻¹, recorded the highest numerical grain yield (61.63 q ha⁻¹), straw yield (77.02 q ha⁻¹), and biological yield (138.66 q ha⁻¹). Several fertilised treatments were statistically comparable with T7 based on the reported critical difference. The highest harvest index was recorded under T10 (44.95%). The findings indicate that integrated Sagarika treatments were associated with favourable rice growth and yield under the conditions evaluated. Multi-season and multi-location studies incorporating economic, soil-health, nutrient-use-efficiency, and environmental measurements are required before wider recommendations are made.

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.

Liquid biofertiliser offers a sustainable alternative to chemical fertilisers for enhancing mungbean (Vigna radiata L.) growth and yield amid increasing global food demand. A field trial was conducted during 2024 and 2025 to determine the effects of seed treatments on early establishment, subsequent vegetative growth, phenology, and productivity. The study was arranged in a randomised block design with 11 treatments: an untreated control; seven individual liquid biofertiliser treatments (Rhizobium, PSB, KSB, VAM, Azospirillum, Pseudomonas, and EM); combined Rhizobium + PSB and Rhizobium + KSB treatments; and a chemical treatment (Thiram). The combined Rhizobium + phosphorus-solubilising bacteria (PSB) treatment recorded the highest values for field emergence (88.32%), plant stand (33.00 plants m⁻²), height (27.43 cm), chlorophyll index (51.80), canopy temperature depression (14.23°C), seed yield per plant (12.57 g), total seed yield (1052.20 kg ha⁻¹), straw yield (1653.89 kg ha⁻¹), and total biological yield (3023.34 kg ha⁻¹), while also recording the earliest flowering (36.67 days) and maturity (56.33 days). The synergistic effects of nitrogen fixation by Rhizobium and phosphorus solubilisation by PSB improved nutrient uptake, increased photosynthetic efficiency in mungbean plants, and supported source-sink relationships. All tested biofertilisers produced higher plant-growth parameters than the control, with the combined treatment showing the best overall performance. Rhizobium + PSB was identified as an effective and environmentally friendly option for increasing mungbean productivity, reducing reliance on chemical fertilisers, and maintaining soil quality and health.

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 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.

Optimising fertiliser application effectively boosts mulberry yields without degrading soil quality in high-density sericulture systems. A field experiment was conducted during 2021–22 and 2022–23 in farmers' fields at Gaddekannuru village, Kolar Taluk, Karnataka, by ICAR–Krishi Vigyan Kendra (KVK), Kolar, to evaluate the efficacy of different liquid microbial formulations on growth, yield, leaf quality, cocoon productivity, and the economics of mulberry (Morus indica L.). The treatments included the recommended dose of fertilisers (RDF) and farmyard manure (FYM) alone (T₁), RDF + Liquid Microbial Consortia (T₂), RDF + Arka Microbial Consortia (T₃), and RDF + Waste Decomposer Solution (T₄), with the microbial formulations applied through drip irrigation at 8 and 25 days after pruning. Pooled data from two consecutive years revealed significant differences among the treatments. Among the treatments, T₂ (RDF + Liquid Microbial Consortia) recorded the highest number of branches (15.40 per plant), leaves (26.36 per branch), leaf yield (1.302 kg per plant and 120.51 q per ha per crop), and cocoon yield (457.96 kg per ha). It also produced superior leaf quality, with the highest leaf moisture content (77.50%), moisture retention capacity (71.90%), total chlorophyll (45.80%), protein (25.10%), and carbohydrate content (16.65%). Economic analysis indicated that T₂ generated the highest gross return (183,184 per ha), net return (132,734 per ha), and benefit–cost ratio (3.63), followed by T₃ (RDF + Arka Microbial Consortia). The results revealed that combining liquid biofertilisers with standard nutrient recommendations significantly improved mulberry biomass, leaf nutritive value, silkworm cocoon output, and net farm profits. The application of liquid microbial consortia through drip irrigation represents a sustainable nutrient-management approach that enhances fertiliser-use efficiency, reduces dependence on chemical fertilisers, and promotes environmentally sustainable sericulture.
