Abstract
In a 2‐year field experiment on a Typic Ustochrept, low in organic carbon and medium in available phosphorus (P), the effects of P fertilizer (0, 30, and 60 kg P2O5 ha−1) and PSB (inoculation and no‐inoculation) and moisture regimens (rain‐fed and irrigated) on soil moisture depletion and grain yield, root growth, nodulation, and P use efficiency of lentil (Lens culinaris) were examined. Application of P significantly increased the seed yield, nodule number, root length and its dry weight, higher moisture depletion, P content in grain and straw and its uptake. Except root length and its dry weight, nodule number, grain and straw yield were higher in irrigated crop compared with unirrigated crop. Inoculation of lentil seed with phosphate‐solubilizing bacteria (PSB) also improved its seed and straw yield besides improving P use efficiency.
