DEVELOPMENT OF FERTILIZER RECOMMENDATION FOR FALLOW-T. AUS-T. AMAN CROPPING PATTERN UNDER SURMA-KUSHYARA FLOODPLAIN SOIL (Pages : 35 - 38)

The experiment was conducted at Golapgonj, Sylhet under Surma-Kushyara floodplain soil for three consecutive years (2001-2003) to find out the optimum fertilizer doses for Fallow-T. aus-T. aman cropping pattern. Six treatments including balanced inorganic fertilizer doses for moderate (ED1) and high yield goal (ED2), integrated nutrient management for high yield goal (INM), recommended fertilizer dose given in Fertilizer Recommendation Guide’97 (FRG’97), farmers’ practice (FP) and absolute control were tested. Fertilizer doses were estimated as per treatment based on soil test values. The highest grain yield was obtained from ED2 in both T. aus (5.23 t/ha) and T. aman (5.15 t/ha) crops, which were closely followed by INM (5.20 and 5.06 t/ha, respectively). Similar trend was observed in straw yield. Gross margin was highest in ED2 (Tk. 76688.53/ha) followed by INM (Tk. 73797.90/ha). The highest marginal benefit cost ratio over control was recorded in ED (7.34) indicating the most economically profitable dose. Download
