Abstract:
A field experiment was conducted during Kharif 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice on the basis of one year experimentation. The treatments which are T1: 100% N through Urea + Azotobacter, T2: 100% N through Urea + KSB, T3: 100% N through Urea + VAM, T4: 100% N through Vermicompost + Azotobacter, T5: 100% N through Vermicompost + KSB, T6: 100% N through Vermicompost + VAM, T7: 50% N through Urea + 50% N through Vermicompost + Azotobacter, T8: 50% N through Urea + 50% N through Vermicompost + KSB and T9: 50% N through Urea + 50% N through Vermicompost + VAM are used. The results showed that application of 50% N through Urea + 50% N through Vermicompost + VAM was recorded significantly Higher Plant height (179.69 cm), No of Leaves/Plant (12.7), Plant dry weight (92.83 g/plant), Crop growth rate (13.7 g/m²/day), No. of Cobs/plant (3.0), Cob Length (20.22), No of rows/cob (15.2), No of grains/row (30.4), Seed Index (26.33 g), Grain yield (4.37 t/ha), Stover yield (14.5 t/ha) and Harvest index (21.88%) as compared to other treatments.
