Effect of Various Levels of Nitrogen, Phosphorus and Potash on the Yield of French Bean

Abstract

The experiment was conducted at the farm of Agricultural Research Station, Baffa (Mansehra) during August 2014 to monitor the effect of various levels of fertilizer treatments on plant height, number of branches plant^-1, pod length, pod weight and pod yield of French bean variety (paulista). The experimental results revealed that that all the fertilizer treatments increased the plant height, number of branches plant^-1, pod length, pod weight and pod yield of French bean significantly over control treatment. Maximum plant height (39.03 cm), number of branches plant^-1(18.25), pod length (14.10 cm),  pod weight (5.37 gm) and pod yield (8.26 t ha^-1) were recorded in the treatment receiving 120 kg N, 90 kg P₂O₅ and 90 kg K₂O ha^-1. The economics of fertilizers were also worked out on the basis of current market prices and it was found that use of fertilizer was profitable. The cost benefit ratio ranged between 4.90. to 6.05.
