Abstract
A study in a sandy clay loam field to investigate the effect of phosphorus rates on the agronomic traits of two mashbean genotypes (Mash-97 and Mash-88) was conducted at the University of Agriculture, Faisalabad during 1998. The phosphorus rates were 0, 50, 7S and lOO kg P205 ha-I. Mashbean genotypes did not differ significantly regarding number of plants m-2, plant height, number of seeds pod-I, total number of seeds plant-I, lOoo-seed weight, seed yield and harvest index. However, Mash-97 gave significantly more seeds per plant than that of the Mash-88. Phosphorus application @ 75 kg ha-I gave significantly the highest seed yield of 1832 kg ha-I against the minimum of 1390 kg ha-I without phosphorus . .~ Key Words: mashbean, genotypes, phosphorus, agronomic traits.
