Genotypic variation for phosphorus efficiency of pigeonpea genotypes under varied phosphorus levels

Enhancement in phosphorus (P) efficiency of crop plants require a better understanding of alterations in root architecture phenes and physio-biochemical processes under phosphorus deprived condition. This study analyzed the morpho-physiological and biochemical alterations associated with P efficiency of crop. Six pigeonpea [Cajanus cajan (L.) Millsp] genotypes (AL1758, AL1817, AL201, H005, ICPL93081, and ICPL88039) were tested under two P treatments [P fertilizer not added in soil and recommended dose of P (Single Super phosphate @ 250kg/ ha)]. Phosphorous use efficient pigeonpea genotypes have ability to take immobile P from P deprived conditions by modifying root architecture.
