| Abstract: |
Expensive phosphatic fertilizers and limited phosphorus (P) availability hamper chickpea production in calcareous soils. Using cheaper P sources could reduce production costs. A field experiment assessed the combined effect of single superphosphate (SSP) and rock phosphate (RP) ratios (RP: SSP; 0:100, 25:75, 50:50, 75:25, and 100:0), phosphate solubilizing bacteria (PSB; with and without), and rhizobium (with and without) on chickpea growth and N and P uptake. RP:SSP ratios of 0:100 and 25:75 yielded higher plant height, growth rate, branch number, N concentration in straw and seeds, crude protein content, and P concentration and uptake in both straw and seeds compared to the 100:0 ratio. PSB application significantly improved chickpea growth, seed and straw N concentration, seed crude protein, and P uptake. Rhizobium-inoculated seeds also enhanced growth, N and P concentration in straw and seed, and P uptake. PSB enhanced rhizobium efficiency by promoting chickpea growth and increasing N and P concentration and uptake through solubilizing low-availability P from RP and SSP. Using RP:SSP (25:75) with PSB and rhizobium is recommended for enhanced chickpea growth and nutrient uptake in calcareous soils. [ABSTRACT FROM AUTHOR] |
