Effect of indole-3-acetic acid and phosphorus on growth and yield of French bean

抄録

The experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from November 2008 to March 2009 to investigate the effect of IAA and phosphorus on the growth and yield of French bean. The experiment consisted of two factors, one factor is three levels of IAA and other factor is four levels of phosphorus. BARI Zhar Sheem-1 was used as a test crop. Application of IAA and phosphorus at different levels had positive impact on growth, yield and yield components of French bean. The highest (17.59 t/ha) green pod yield of French bean was observed in 30 ppm IAA application and the lowest (12.50 t/ha) was obtained from control treatment. On the other hand, the highest (18.16 t/ha) green pod yield was recorded from 130 kg P₂O₅/ha application and the lowest (12.63 t/ha) was obtained from control treatment. The highest green pod yield (18.97 t/ha) was obtained from the combination of 30 ppm IAA and 130 kg P₂O₅/ha application plot and the lowest (10.00 t/ha) was in control condition. The maximum (3.65) benefit cost ratio was obtained due to application of 30 ppm IAA and 130 kg P₂O₅/ha, while the lowest (2.07) in control condition. Therefore, the best results were obtained from 30 ppm IAA and combination with 130 kg P₂O₅/ha.
