Abstract
Low soil P levels pose major limitation in realizing optimal growth and development of grain legumes and yet the suitable P levels of common chickpea cultivars (i.e. Black gram and Benazir) are not on the record. Effect of various P application levels (0, 25, 50 and 75 kg P2O5 ha-1 ) on two chickpea cultivars was evaluated in a field study using randomized complete block design. All the treatments received recommended dose of N and K2O (each at 30 kg ha-1 ) in the form of urea and SOP, respectively. Application of P resulted in significant increase in plant height (102.4 cm), number of branches (31.1 plant-1 ) and grain yield (1058 kg ha-1 ), shoot P (0.49%), P uptake (5.18 kg ha-1 ) and protein content (17.4%) over control. Increasing the P levels from 50 to 75 kg P2O5 ha-1 did not have any significant effect on number of branches (30.4 to 31.1 plant-1 ). As for cultivars, a significant effect was observed for grain yield (p
