Maize Yield Response to Organic Fertilizers and Biofertilizers in a Sub-Tropical Zone of Eastern Himalayan Region of Arunachal Pradesh, India

Abstract

A Field experiment was conducted at the Department of Agriculture at Himalayan University, Jullang, Arunachal Pradesh, to assess the impact of composts and biofertilizers on plant growth. The available soil nutrient status were medium in N, High in P and medium in K in study soil.The treatments considered of T1- Control 100 % RDF, T2 - Vermicompost 0.5 Kg/ha + Phosphorus solubilizing bacteria 0.5Kg/ha, T3 – Poultry manure 0.5 Kg/ha + Azotobacter 0.5Kg/ha, T4 – Compost 0.5Kg/ha + Phosphorus solubilizing bacteria 0.5Kg/ha + Azotobacter 0.5Kg/ha, T5 – compost 0.5Kg/ha + Phosphorus solubilizing bacteria 0.5 Kg/ha , T6 – Poultry manure 0.5Kg/ha+ Azotobacter 0.5Kg/ha, T7 – Vermicompost 0.5Kg/ha + Phosphorus solubilizing bacteria 0.5Kg/ha + Azotobacter 0.5Kg/ha.The highest cob plant-1 recorded highest in treatment receiving Vermicompost 0.5 Kg/ha + Phosphorus solubilizing bacteria 0.5 Kg/ha + Azotobacter 0.5 Kg/ha(T7) i.e 1.93. highest cob length recorded 13.80 cm receiving treatment Vermicompost 0.5Kg/ha+ Phosphorus Solubilizing Bacteria 0.5Kg/ha + Azotobacter 0.5Kg/ha (T7).The highest number of cob grain-1 is 394.47 receiving Vermicompost 0.5Kg/ha + Phosphorus solubilizing bacteria 0.5Kg/ha + Azotobacter 0.5Kg/ha (T7) and 12.03 g of test weight were obtained with treatment (T7) receiving Vermicompost 0.5Kg/ha + Phosphorus solubilizing bacteria 0.5Kg/ha + Azotobacte 0.5Kg/ha .
