Abstract
A field experiment was conducted at the Agriculture Research Station, Achalpur, District Amravati, under Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, during the kharif 2024-25 season to evaluate the efficacy of HYPER on the growth, yield and soil nutrient status of blackgram (Udid). A plant bio-stimulant is any substance applied to plants to enhance nutrient-use efficiency, abiotic stress tolerance and crop-quality traits, regardless of its nutrient content. The field topography was fairly uniform and levelled. The experiment was laid out in a Randomised Block Design with six treatments and four replications. The mean number of seeds per pod (5.45) was significantly higher under Urea Briquette and T5: RDF + HYPER at 2.5 ml/litre of water. Grain yield was significantly highest under T6: RDF + HYPER at 3 ml/litre of water (1196.23 kg ha-1), and it was at par with T4: RDF + HYPER at 2 ml/litre of water (1151.91 kg ha-1). RDF + HYPER at 3 ml/litre of water recorded the highest grain yield (1196.23 kg ha-1), followed by RDF + HYPER at 2.5 ml/litre of water (1165.03 kg ha-1). Growth parameters, including plant height, number of branches and pod characteristics, improved significantly with HYPER application. Post-harvest soil nutrient availability also increased in treated plots, with the highest available N (213.25 kg ha-1), P (18.14 kg ha-1) and K (652.85 kg ha-1) recorded under T6. The findings indicate that RDF + HYPER at 3 ml/litre of water significantly enhanced blackgram productivity and post-harvest soil fertility under Vertisol conditions.
Mungbean (Vigna radiata), an important pulse crop for nutritional security in India, often exhibits low productivity due to poor soil fertility and imbalanced nutrient management. A field experiment was conducted during the Zaid season of 2024 at the Students Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, to evaluate the effect of foliar nutrition and nano-fertilizers on growth, yield and protein content. The experiment was laid out in a randomized block design with eight treatments and three replications. Plant population remained non-significant across treatments, with the highest values recorded under 75% NPK + nano urea at 25 DAS + nano DAP at 40 DAS (22.89 plants m⁻² at 30 DAS and 22.52 plants m⁻² at harvest). Growth parameters were significantly improved under this treatment, recording the highest plant height (49.87 cm), number of branches per plant (5.84), dry matter accumulation (14.62 g plant⁻¹), number of root nodules (18.76 plant⁻¹), and nodule dry weight (0.42 g plant⁻¹). Yield attributes were also maximized, including pods per plant (14.58), seeds per pod (8.94), pod length (6.49 cm), seed weight per plant (3.98 g), and pod weight per plant (5.24 g), while test weight was non-significant but highest (41.17 g). Consequently, the same treatment produced the highest biological yield (1877.21 kg ha⁻¹), seed yield (713.14 kg ha⁻¹), protein content (24.07%), and protein yield (204.51 kg ha⁻¹). The findings indicate that integrating 75% recommended NPK with foliar application of nano urea and nano DAP enhances nutrient use efficiency, improves growth and yield attributes, and offers a sustainable strategy for increasing mungbean productivity and quality.

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.

A field experiment was conducted during the kharif season of 2025 at the Crop Research Centre, School of Agriculture, ITM University, Gwalior, Madhya Pradesh, to study the effect of phosphorus levels and organic manures on the growth, physiological indices and yield of black gram [Vigna mungo (L.) Hepper]. The experiment was laid out in a Factorial Randomized Block Design with three replications. The treatments comprised three phosphorus levels (40, 50 and 60 kg P₂O₅ ha⁻¹) and three organic manure sources, namely farmyard manure (FYM) at 5 t ha⁻¹, vermicompost at 2 t ha⁻¹ and poultry manure at 1.5 t ha⁻¹, along with an absolute control. Phosphorus application significantly improved growth, nodulation, dry matter accumulation, physiological growth indices and yield. The highest plant height (52.90 cm), number of branches plant⁻¹ (7.36), leaf area index (3.62), root nodules plant⁻¹ (27.20), dry matter accumulation at harvest (439.34 g m⁻²), crop growth rate (6.43 g m⁻² day⁻¹ during 40–60 DAS), grain yield (1412 kg ha⁻¹) and straw yield (3130 kg ha⁻¹) were recorded with 60 kg P₂O₅ ha⁻¹. Among organic manures, vermicompost at 2 t ha⁻¹ produced the highest grain yield (1422 kg ha⁻¹) and straw yield (3045 kg ha⁻¹). The application of 60 kg P₂O₅ ha⁻¹ with vermicompost at 2 t ha⁻¹ may improve the productivity of black gram under the conditions of the present study.

The present investigation was carried out during the Rabi season of 2026 to evaluate the effect of different organic nutrient sources on the growth performance of knol-khol (Brassica oleracea L. var. gongylodes) under Bundelkhand conditions. The Organic Agriculture Farm, Karguan Ji, Bundelkhand University, Jhansi, under a semi-arid subtropical climate on sandy loam soil with neutral to slightly alkaline pH (7.48) and medium fertility status. The initial soil contained 0.48% organic carbon, 236.5 kg ha⁻¹ available nitrogen, 19.2 kg ha⁻¹ available phosphorus, and 247.8 kg ha⁻¹ available potassium, providing suitable conditions for evaluating organic nutrient management. The uniform soil fertility and favorable climatic conditions ensured reliable treatment comparisons, as reflected by the low coefficients of variation and highly significant treatment effects observed in the ANOVA. The experiment was laid out in a Randomized Block Design (RBD) comprising eight treatments with three replications. The treatments consisted of Panchagavya (4%), Jivamrita (20%), Vermiwash (1:5 dilution), their different combinations, Recommended Dose of Fertilizers (RDF: 120:30:30 kg NPK ha⁻¹), and an untreated control. Growth parameters such as plant height, number of leaves per plant, and leaf area were recorded at harvest. The results indicated significant differences among treatments. The combined application of Panchagavya (4%) and Jivamrita (20%) (T4) recorded the highest plant height (35.6 cm), maximum number of leaves per plant (18.7), and largest leaf area (400.5 cm²), followed by Panchagavya (4%) + Vermiwash (1:5 dilution) (T5). The control treatment recorded the lowest values for all growth attributes. The superior performance of integrated organic treatments was attributed to improved nutrient availability, enhanced microbial activity, increased production of plant growth-promoting substances, and improved soil fertility. The study concludes that integrated application of Panchagavya and Jivamrita is an effective and sustainable nutrient management strategy for enhancing vegetative growth of knol-khol under Bundelkhand agro-climatic conditions.

A field experiment was conducted during the rabi season of 2025-26 at the Agriculture Research and Development Centre, Sakatpura, School of Agriculture Science, Vikrant University, Gwalior, Madhya Pradesh, to evaluate the yield and economic responses of Indian mustard (Brassica juncea L.) to biochar-based nutrient management. The experiment was laid out in a randomised block design with eight treatments and three replications. The treatments comprised an absolute control, 100% of the recommended dose of fertilizer (RDF: 80:40:40:40 kg N:P₂O₅:K₂O:S ha⁻¹), and 100% or 75% RDF combined with mustard stover, Lantana camara, or wood/forest residue biochar @ 5.0 t ha⁻¹. The highest yield attributes were obtained with 100% RDF + Lantana camara biochar @ 5.0 t ha⁻¹ (T₄), which recorded 340.00 siliquae plant⁻¹, 14.60 seeds siliqua⁻¹, and a 1,000-seed weight of 5.21 g. The same treatment produced the maximum seed yield (21.72 q ha⁻¹), stover yield (44.00 q ha⁻¹), biological yield (65.72 q ha⁻¹), gross returns (₹1,52,320 ha⁻¹), and net returns (₹1,03,720 ha⁻¹). However, 75% RDF + Lantana camara biochar @ 5.0 t ha⁻¹ (T₇) recorded the highest benefit:cost ratio (3.14), with a comparable seed yield of 20.67 q ha⁻¹. The results indicated that integrating lantana biochar with fertilizer improved mustard productivity and profitability, while 75% RDF + lantana biochar may serve as a fertilizer-saving option where local biochar material is available.

A field experiment was conducted during the kharif seasons of 2024 and 2025 at the College of Agriculture, S.K. Rajasthan Agricultural University, Bikaner, Rajasthan, India. The experiment comprised seven weed management practices and four iron fertilisation levels, resulting in 28 treatment combinations. These treatments were evaluated in a factorial randomised block design with three replications. Groundnut variety HNG-123, a semi-spreading (Virginia bunch) cultivar, was sown at a seed rate of 100 kg ha⁻¹ with a spacing of 30 cm × 10 cm. The results revealed that weed management practices and iron levels significantly influenced the nodulation and yield attributes of kharif groundnut. Among the weed management treatments, the weed-free treatment recorded the highest number of nodules (67.39 plant⁻¹), nodule dry weight (1.92 g plant⁻¹), pods per plant (19.95) and kernels per pod (1.98). Pendimethalin @ 0.75 kg a.i. ha⁻¹ as pre-emergence followed by fomesafen + fluazifop-p-butyl @ 25 g a.i. ha⁻¹ at 20 DAS recorded 65.50 nodules plant⁻¹ and remained statistically at par with the weed-free treatment. In contrast, the weedy check consistently recorded the lowest values for all these parameters. Among the iron levels, the application of 6 kg FeSO₄ ha⁻¹ as a basal dose along with two foliar sprays of FeSO₄ @ 0.5% at 30 and 45 DAS significantly improved nodulation and yield attributes, recording the highest number of nodules (62.32 plant⁻¹), nodule dry weight (1.67 g plant⁻¹), pods per plant (19.02) and kernels per pod (1.57). The seed index remained statistically unaffected by weed management practices and iron levels.
