INTEGRATED NUTRIENT MANAGEMENT FOR POTATO- MUNGBEAN-T.AMAN RICE CROPPING PATTERN UNDER LEVEL BARIND AGROECOLOGICAL ZONE

A field experiment was conducted at the Multiplication Testing Site (MLT), Joypurhat Sadar upazila with Potato- Mugnbean –T. Aman rice cropping pattern during November/2007 to November/2008 to verify different nutrient management approaches and to determine the economic dose of fertilizer for the said cropping pattern. The experiment was designed with five treatments for whole of the cropping pattern in a randomized complete block design with six replications. The treatments were, soil test based fertilizer dose for moderate yield goal, soil test based fertilizer dose for high yield goal, integrated plant nutrient management, farmers ’ practice, and control. Cowdung was applied at the first crop potato only in the cropping sequence. The varieties for potato, mungbean and T. Aman rice were Diamant, BARI Mung-6, and BR11, respectively. The results demonstrated that the tuber yield of potato, seed yield of mungbean, and grain yield of T. Aman rice were significantly influenced by the different treatments. The highest tuber yield (25.01 t/ha) was obtained fro
