Effect of Integrated Nutrient Management on Growth and Yield Parameters of Maize (Zea mays L.)

Aim: To study effect of integrated nutrient management on growth and yield of maize (Zea mays L.).

Study Design: A field experiment was conducted at the Crop Research Farm, Department of Agronomy, AKS, University, Satna during Rabi season 2023 on Maize crop.

Methodology: The experiment trail was laid out in randomized block design. It consisted of three replications with ten treatment combinations i.e. T1 - Control,, T2 - 100% RDN by FYM (24 t/ha),, T3 - 75% RDN by FYM+25% RDN by VC,, T4 - 75%RDN by FYM+25% RDN by VC + Azotobacter and PSB @ 10 ml/kg seed,, T5 - 100% RDN by VC (8 t/ha),, T6 - 75% RDN by VC+25% RDN by FYM,, T7 -75%RDN by VC+25% RDN by FYM+ Azotobacter and PSB @ 10 ml/kg seed,, T8 - 50% RDN by VC + 50 % RDN by PM (3.8 t/ha),, T9 - 50% RDN by VC+50% RDN by PM + Azotobacter and PSB @ 10 ml/kg seed,, T10 - 50%RDN by EC (6 t/ha) + Beejamrut + Jeevamrut spray 500 l/ha (twice).

Results: The results showed that application of T9 50% RDN by VC + 50% RDN by poultry manure + Azotobacter + PSB had significant effect on growth and yield of maize. The plant height, number of leaves per plant and dry matter accumulation were also significantly higher in T9 followed by T8 50% RDN by VC + 50 % RDN by PM (3.8 t/ha). The highest grain yield (39.40 q ha-1) was obtained in T9 followed by T8 (38.15 q ha-1), T7 (37.62 q ha-1) andT5(36.73 q ha-1).
