Abstract:
The research study was conducted at experimental farm of Department of Soil science and Agriculture Chemistry, Sam Higginbottom University of Agriculture Technology and Sciences, Allahabad during Kharif season 2016-17 to evaluate the effect of different levels of NPK, Micronutrient, Neem cake and PGPR on plant growth and yield of maize. The Experiment was carried out in randomized block design with three levels of NPK, Neem cake, micronutrient and plant growth promoting rhizobacteria. The treatments were replicated three times and were allocated at randomly in each replication in which the results showed that increase in plant height 30, 60 and 90 DAS (@86.52,168.68, 175.64 cm respectively), Number of leaf per plant 30, 60 and 90 DAS(@ 7.20, 12.40, 12.60 respectively), Dry weight (164.07g), Length of cob (18.32cm), Number of grain per cob (307.07), Test weight (216.31g), Grain yield (44.60 qha^-1) found in treatment T₈- [I₂+N₂] (@100%N:P:K, Zinc+ 100% Neem cake and PGPR or N₁₂₀ P₆₀ K₆₀ Zn₂₀ Kgha^-1 + Neem Cake₁₀ qha^-1 PGPR200g 10kg^-1 seed) followed by T₇ as compared to control (T₀). Therefore, the research study exhibited that the significant increase on enrichment of Plant growth and yield of maize with combination of N: P: K, Zinc and Neem cake and PGPR.
