Phosphorus use efficiency as influenced by np ratios to pigeonpea and fertilizer levels to intercrop in pigeonpea + blackgram system

In general, the phosphorus use efficiency is less as only 30 % of the applied phosphorus is taken by plants in its entire growing season and phosphorus recovery efficiency of applied fertilizers in soil by the crop plant is less than 20 % (Fageria et al., 2011). Intercropping system is one of the best strategies to improve PUE (Hasan et al., 2016).
