<p class="Default">An experiment was conducted to investigate the impact of flatbed (FB), ridges and furrows (RF) and broad bed furrows (BBF) combined with recommended fertilizer dose N30P60K30 kg ha−1 (F1), 75 % NPK (F2), 125 % NPK (F3), 75 % NPK + 25 % N through farm yard manure (FYM)-F4, 75 % NPK + 2 sprays of micro nutrient mixture (Fe, Zn, Cu, Mn, B and Mo) - 0.5 % at 35 and 60 days after sowing (DAS)-F5 and 75 % NPK + 2 sprays of KNO3 - 0.5 % at 35 and 1.0 % at 60 DAS (F6) on the

A significant 3.76 kg ha−1-mm rain water use efficiency was notice in BBF compared to FB. The yield increment recorded under F6 was 15.6 % higher than F1. Grain nitrogen and oil contents were highest in F3. The residual soil fertility was much improve by F3 and F5. Our result demonstrated that the combination of BBF and F6 were the best technique to increase soybean yield in the Vertisol soil.</p>
