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 of experimentation. The treatments which are T1- Control (120 kg N/ ha: 60kg P2O5/ ha: 60kg K2O/ha.), T2- Vermicompost- 3.3 t/ha + Urea- 130.5 kg/ha + Zinc- 5 kg/ha, T3- Vermicompost- 3.3 t/ha + Urea- 130.5 kg/ha + Boron- 0.5 kg/ha, T4- Vermicompost- 3.3 t/ha + Urea- 130.5 kg/ha + Zinc- 5 kg/ha + Boron- 0.5 kg/ha, T5- Neem cake- 1.154 t/ha + Urea- 130.5 kg/ha + Zinc- 5 kg/ha, T6- Neem cake- 1.154 t/ha + Urea- 130.5 kg/ha + Boron 0.5 kg/ha, T7- Neem cake -1.154 t/ha + Urea- 130.5 kg/ha + Zinc- 5kg/ha + Boron- 0.5 kg/ha, T8- Vermicompost- 1.66 t/ha + Neem cake- 0.57 t/ha + Urea- 130.5 kg/ha + Zinc- 5 kg/ha, T9- Vermicompost- 1.66 t/ha + Neem cake- 0.57 t/ha + Urea- 130.5 kg/ha + Boron- 0.5 kg/ha, T10- Vermicompost- 1.66 t/ha + Neem cake- 0.57 t/ha + Urea- 130.5 kg/ha + Zinc- 5 kg/ha + Boron- 0.5 kg/ha used. The results showed that application of Vermicompost- 1.66 t/ha + Neem cake-0.57 t/ha + Urea- 130.5 kg/ha + Zinc- 5 kg/ha + Boron- 0.5 kg/ha was recorded maximum plant height (207.20 cm), plant dry weight (179.52 g/plant), crop growth rate (41.38 g/m2/day), number of cobs per plant (1.80), length of cob (17.43 cm), diameter of cob (12.37 cm), number of grains per Cob (358.27), test weight (254.16 g), grain yield (9.73 t/ha), straw yield (21.20 t/ha) and harvest index (31.45) as compared to other treatments.
