Abstract

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
