Abstract
The experiment was carried out in a Randomized Block Design treatments 8 viz. T1 Control,T2 FYM @ 30 t/ha) + biofertilizer (PSB), T3 poultry manure @ 5 t/ha + biofertilizer (PSB),T4 vermicompost @ 7.5 t/ha + biofertilizer (PSB), T5 FYM @ 10 t/ha + poultry manure @ 1.7 t/ha +vermicompost 2.7 t/ha + biofertilizer (PSB), T6 67% RDF through inorganic sources + 33% RDF through organic sources i.e. FYM + biofertilizer (PSB), T7 33% RDF through inorganic sources + 67% RDF through organic sources i.e. FYM + biofertilizer (PSB) and T8 Farmer practices (through organic). All the treatment combinations were replicated three times. The soil of the experiment field was silty loam in texture and medium in fertility status with the pH values 8.1, organic carbon 0.31%. The available nitrogen, phosphorus and potassium were 140.0, 15.2, and 240 kg ha-1 respectively.
