Abstract

Aim: To find out the suitable combination of phosphorus (P) and boron (B) for higher yield and nutrient uptake of black gram.

Methodology: A field experiment was conducted during kharif 2018 in acid Inceptisol with four levels of phosphorus (0, 25, 50 and 75 kg P ha-1 soil) and four levels of boron (0, 0.5, 1.0, 1.5 kg B ha-1) in 16 treatment combinations laid out in split plot design. P was kept in main plot whereas B in sub plot and replicated thrice. Black gram (var. PU-31) was raised as test crop.

Results: The experimental results showed increase in seed yield, stover yield, phosphorus and boron concentration and uptake with increasing doses of P and B. The combined application of 50 kg P2O5 ha-1 and 1.5 kg B ha-1 has resulted in significantly higher seed yield, whereas, significant higher stover yield was produced with the combined application of 50 kg P2O5 ha-1 and 1.0 kg B ha-1. Significant higher phosphorus concentration and uptake in seed and Stover was observed with the application of 75 kg P2O5 ha-1 and 1.5 kg B ha-1, whereas, the combined application of 50 kg P2O5 ha-1 and 1.5 kg B ha-1 significantly increased boron uptake by seed and Stover as 50 kg P2O5 ha-1 and 1.0 kg B ha-1.      

Interpretation: The application of 50 kg P2O5 kg ha-1 and 1.5 kg B ha-1 is the appropriate combination for getting higher yield of black gram in acid Inceptisol of Meghalaya.      

Key words: Acid soil, Black gram, Boron,  Nutrient uptake, Phosphorus
