Productivity and profitability of soybean as influenced by phosphorus and molybdenum fertilization in an acid Alfisol
Keywords:
<i>Alfisol</i>, phosphorus, molybdenum, soybeanAbstract
A field experiment was conducted during kharif 2021 on soybean at Palampur on silt-clay loam soil (acid Alfisol). Graded levels of 0, 30, 60 and 90 kg of P2O5 ha-1 and 0, 1.0 and 2.0 kg of Mo ha-1 were integrated to frame 2 5 twelve treatments which were arranged in randomized complete block design, replicated thrice. Application of phosphorus and molybdenum significantly influenced the grain and biological yield up to 90 kg P2O5 (24.8 q ha-1 and 64.2 q ha-1) and 2.0 kg Mo ha-1 (22.1 q ha-1 and 57.7 q ha-1 respectively) along with high net returns and B:C ratio. In contrary, significant increase in straw yield was registered only up to 30 kg P2O5 ha-1. The interaction between varied phosphorus and molybdenum levels had no impact on yield. Application of 90 kg P2O5 alongside 2.0 kg Mo ha-1 proved superior in enhancing productivity and profitability of soybean under acid Alfisol.
