  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.

  Response of two sorghum cultivars namely Hegari and JS-263 to different NP levels of 0-0, 50-0, 100-0, 50-50, 100-50 and 100-100 kg ha–1 was studied under field conditions. The cultivar Hegari gave significantly higher green fodder and dry matter yield due to greater plant height, stem diameter and leaf area plant–1. The crude fiber per cent and ash per cent were also significantly higher for cultivar Hegari. A progressive increase in yield was observed with fertilizer application up to 100 kg N + 50 kg P205 ha–1 whereas, the quality parameters such as protein content, crude fiber and ash percent were significantly higher with NP application of 100 + 100 kg ha–1. The cultivar Hegari and fertilizer level of 100 kg N + 50 kg P205 ha–1 seems to be the best combination for harvesting higher fodder yield of sorghum under Faisalabad conditions.
