Abstract

The present study compares the effects of phosphorus (P) on growth and bioaccumulation of a high-zinc-accumulating genotype (HZnG) and a low-zinc-accumulating genotype (LZnG) of chickpea (Cicer arietinum L.). A green house experiment was conducted in clay-pots filled with sand, at constant zinc (Zn) level with application of varying doses (0, 13.5 and 27 mg kg-1 of sand) of P, under naturally illuminated condition. Biomass production in shoot and root, and the Zn and P accumulation in the shoot were measured 90 days after sowing (DAS). P inputs affected all these parameters significantly in both the genotypes. High supply of P had inhibitory effect on most of these traits. An inverse relationship between the Zn and P accumulations in shoot was noticed at the highest dose (27 mg kg-1 of sand) of the applied P. HZnG did better than LZnG with all levels of P supply except for P concentration and content. Phosphorus application at the rate of 13.5 mg kg-1 of sand was optimum for both the genotypes tested. It has emerged from the study that HZnG chickpea genotype is suitable for zinc-deficient soils and may help in resisting low P availability in the soil.
