Abstract
The experiment was conducted at Golapnagar char of the Padma River under Bheramara Upazila in Kushtia district and at Bhuapur char of the Jamuna River in Tangail district to find out optimum and economic fertilizer dose for higher yield of BARI Sarisha-11 in charland areas during rabi seasons of 2009-10 and 2010-11. Five fertilizers doses, viz. ORC based (115-33-43-27-2-2 kg ha-1 of NPKSZnB), AEZ based, Soil test based, Farmers’ dose and Native fertility were tested on BARI Sarisha-11. AEZ based, soil test based and farmers’ dose for Golapnagar char were 84-18-33-10-0.5-1, 127-39-62-28-1.5-1 and 70-15-38-20-0-0 kg ha-1 of NPKSZnB while for Bhuapur char were 54-17-23-12-1-0.5, 119-38-87-16-2-1 and 52-15-28-0-0 kg ha-1 NPKSZnB, respectively. Siliquae plant-1, seeds siliqua-1, 1000-seed weight and seed yield of BARI Sarisha-11 were highest in soil test based fertilizer dose at both the locations. Gross return, gross margin and benefit cost ratio (BCR) were also highest with same fertilizer dose. The results of this study revealed that soil test based fertilizer dose might be economically profitable for growing BARI Sarisha-11 at Golapnagar char (127-39-62-28-1.5-1kg ha-1 of NPKSZnB) in Kushtia and Bhuapur char (119-38-87-16-2-1 kg ha-1 of NPKSZnB) inTangail districts.
