Background: Bioinoculants and biostimulants are gaining importance as sustainable approaches for improving fodder productivity and nutritive quality in forage crops. Their integration with organic nutrient sources may enhance nutrient availability, plant growth and forage quality. Therefore, the present investigation was undertaken to evaluate the effect of bioinoculants and biostimulants on fodder yield, proximate composition and fibre fractions of berseem (Trifolium alexandrinum L.). Methods: A field experiment was conducted during the rabi seasons of 2023-24 and 2024-25 at the Agronomy Research Farm of ICAR-National Dairy Research Institute in a randomized block design with six treatments and six replications. Result: Among the treatments, PGPR + 75% recommended dose of nitrogen (RDN) through FYM + three foliar sprays of Panchagavya recorded the highest green fodder yields of 57.0 and 58.5 t ha-1 and dry fodder yields of 7.6 and 8.1 t ha-1 during 2023-24 and 2024-25, respectively, over the absolute control. The treatment also significantly improved dry matter, crude protein, ether extract and total ash contents while reducing acid detergent fibre, neutral detergent fibre and acid detergent lignin contents. The findings indicated that integrated application of PGPR, FYM and Panchagavya is an effective and sustainable nutrient management strategy for improving fodder productivity and nutritive quality of berseem under organic production conditions.

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
