Site Specific Nutrient Management for Sugarcane-potato And Sugarcane-onion in Intercropping Systems

S.M. Bokhtiar, M.S. Hossain, K. Mahmud and G.C. Paul    

Abstract: Four field experiments were conducted under different Agro-ecological zones (AEZs) of Bangladesh at Ishurdi (AEZ 11), Jamalpur (AEZ 9), Rajshahi (AEZ 11) and Thakurgaon (AEZ 1) in 2001-2002 cropping season. The main aims of the studies were to determine the fertilizer requirements on productivity of cane and intercrops (potato and onion) and their economics under sugarcane based cropping systems. Cane yield was enhanced when it was intercropped with potato and onion for the residual effect of applied fertilizer to intercrops. Net economic return was greater in cane intercropped with potato and onion over sole crop for all the experiments. Intercropping potato with sugarcane using FRG’97 rates of fertilizer for cane (130 kg N, 35 kg P, 60 kg K, 20 kg S and 3 kg Zn ha-1) and potato (50 kg N, 10 kg P and 20 kg K ha-1) gave higher economic benefit at Ishurdi site. In Jamalpur site, sugarcane intercropped with potato following fertilizer rates based on BSRI’98 for cane (150 kg N, 42 kg P, 100 kg K, 30 kg S and 2 kg Zn ha-1) and potato (50 kg N, 10 kg P and 40 kg K ha-1) gave the highest net profit. But, the treatment received fertilizers as per FRG’97 showed higher economic benefit from sugarcane-onion intercropping systems both at Rajshahi and Thakurgaon sites.
