Abstract

A study on wheat (Triticum áestivum L.)-rice (Oryza sativa L.) cropping system using six different nutrient management practices was conducted during 2002-2004 in Panchagarh, under Agroecological Zone 1 in Bangladesh for the development of cropping pattern-based fertilizer recommendations. The six different nutrient management treatments were as follows: soil test-based inorganic fertilizer doses for moderate yield goal (MYG), soil test-based inorganic fertilizer doses for high yield goal (HYG), integrated nutrient management for HYG (INM), Agroecological Zone-based standard fertilizer recommendations given in Fertilizer Recommendation Guide '97 (FRG '97), local farmers' practice (FP) and unfertilized control. The combined use of organic and inorganic fertilizer could increase system productivity compared with the use of inorganic fertilizer alone. In general, soil test-based fertilizer doses performed better than fertilizer applied at standard doses without prior soil testing. Based on the 2-yr study, soil test-based INM treatment produced the highest crop yields, improved yield-contributing characters, resulted in the highest gross margin and gave the highest marginal benefit cost ratio over the unfertilized control compared with the other nutrient management practices. Under such conditions, the application of farm yard manure in the form of cow dung in the INM treatment was found useful in increasing crop yields. To increase soil fertility and sustainable crop productivity, the farmers in Bangladesh should be encouraged to use farm yard manure such as cow dung along with INM treatment for wheat-rice cropping system.
