Abstract:
A field experiment was conducted by substituting the recommended dose of phosphorus from 25-50% to sugarcane plant crop with VAM and PB alone and combination of both and was evaluated with 100%, 75% and 50% of recommended dose of Phosphorus in eight treatments which were replicated thrice in RBD design. The variety of sugarcane used was 99V 30. The treatments includes T₁ - 100% P; T₂ - 75% P; T₃ - 50% P; T₄ - 50% P + VAM @5kg/ha + PB@8kg/ha; T5 - 75% P + VAM @5kg/ha; T₆ - 50% P + VAM @5kg/ha; T₇ - 75% P + PB@8kg/ha and T₈ - 50% P + PB @8kg/ha. Yield parameters, cane yield, commercial cane sugar yield, nutrient uptake of nitrogen and phosphorus and phosphorus availability in post-harvest soils by sugarcane plant crop were more with T₁ (100% recommended dose of phosphorus) and were on par with T₄ where 50% recommended Phosphorus and 50% was substituted with combination of VAM @5kg/ha + PB @8kg/ha.
