Abstract:

Significantly higher grain and straw yield (5159 kg ha-1) of paddy was recorded in package of practice (POP- FYM 5 t + 60:30:45 kg N:P2O5:K2O ha-1) +50 per cent N through vermicompost, respectively, followed by POP + 50 per cent N through poultry manure (5101 kg ha-1) as compared to package of practice (4425 and 5509 kg ha-1, respectively). Significantly higher total nitrogen and phosphorus uptake was observed in package of practice (POP) + 50 per cent N through vermicompost (109.85 and 45.51 kg ha-1, respectively) followed by POP + 50 per cent N through poultry manure (107.96 and 44.92 kg ha-1, respectively). Total potassium uptake was recorded highest in POP + 50 per cent N through eupatorium (60.23 kg ha-1), it was followed by POP + 50 per cent N through poultry manure (59.33 kg ha-1). Maximum available nitrogen (375.90 kg ha-1) was observed in POP + 50 per cent N through gliricidia followed by POP + 50 per cent N through eupatorium (375.03 kg ha-1). Available P2O5 (74.60 kg ha-1) was more with POP + 50 per cent N through poultry manure followed by POP + 50 per cent N through goat manure (73.26 kg ha-1). Application of recommended dose of nutrients i.e. POP (FYM 5 t + 60:30:45 kg N: P2O5: K2O ha-1) + 50 per cent N through eupatorium and POP + 50 per cent N through vermicompost resulted in higher available K2O (135.43 and 134.13 kg ha-1, respectively). Significantly higher population of bacteria, fungi and actinomycetes (27.27 cfu x 105 g-1, 34.86 cfu X 103 g-1 and 13.24 cfu X 104 g-1 of soil, respectively) was found with POP + 50 per cent N through vermicompost.
