Abstract:

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. Roots of these P use efficient genotypes syntheses and secrete enzyme i.e acid phosphatase (APase) in rhizosphere which solubilize the organic P of soil and make it available to plant uptake. Genotypes such as H005, ICPL88039 and ICPL93081 exhibited 8.6%, 6.9% and 1.8% increase in root area under no added P condition, respectively. The activity of APase enzyme was recorded highest in P use efficient genotypes under P not added condition at all growth stages while less enzyme activity was determined in these genotypes under P recommend dose condition. It revealed that these pigeonpea genotype syntheses more APase to mobilize the unavailable form of soil P.
