Abstract
The experiment was carried out at the research field of Sher-e-Bangla Agricultural University, Dhaka during December 2004 to March 2005 to study the effect of nitrogen and phosphorus on the yield of bush bean. Treatments consisted of three levels of N viz., 0, 20 and 40 kg N/ha and four levels of phosphorus viz., 0, 50, 75 and 100 kg P2O5/ha. There were 12 treatment combinations. Results showed that different levels of nitrogen significantly influenced bush bean yield. The highest level of nitrogen i.e 40 kg N/ha produced the highest green pod (16.56 t/ha) and seed yield (2.71 t/ha). Phosphorus also significantly influenced bush bean yield where the highest yields (green pod yield 15.35 t/ha and dry seed yield 2.58 t/ha) were obtained when fertilized with 75 kg P2O5/ha. The combined effect of nitrogen and phosphorus was also significant. The highest green pod yield (18.61 t/ha) was obtained when 40 kg N/ha was applied along with 75 kg P2O5 /ha and this combination of treatments also gave the highest benefit cost ratio (5.11).
