其他摘要：The experiment was conducted at the research field of Agronomy Division, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during Rabi (winter) season of 2010-11 to 2011-12 to determine the optimum rate of nitrogen and phosphorus fertilizer on yield and seed quality of French bean. A randomized complete block design was followed with ten treatment combinations such as N 0 P 0 , N 0 P 44 , N 50 P 44 , N 100 P 44 , N 150 P 44 , N 200 P 44 , N 150 P 0 , N 150 P 22 , N 150 P 33 and N 150 P 55 . Number of pods and yield of French bean were significantly increased with the increase in N (150) and P (44) kg ha --1 . Averaged over the years, maximum number of pod (9.45 plant -1 ) and seed yield (1563.33 kg ha -1 ) were obtained when N and P were applied at the rate of 150 and 44 kg ha -1 , respectively while lowest yield to N 0 P 0 treatment in both the years. The treatment (N 150 P 44 kg ha -1 ) gave the highest seed yield which was 51.4 and 54.30% higher than the control. Quality in terms of germination percentage and vigour index of harvested seed was also significantly influenced by higher doses of N and P while the lowest seed quality from plants that received no fertilizer in both the years.
