Abstract/ Executive Summary:

The study was conducted at Regional Sugarcane Research Station, Thakurgaon experimental farm located in Old Himalayan Piedmont Plain Soils (AEZ1) of Bangladesh during 2002-2003 cropping season. The soil of the experimental site is sandy with high land having pH 5.00, low in total N (0.07 per cent), available P (11.00 ppm), K (0.15 meq %) and S (9.00 ppm). The climate of this location is sub-tropical. The experiment was laid out in a split plot design with three replications. Three budded cuttings of the studied clones/variety (one standard variety lsd 31 and four clones of I 8-95, I 122-95, I 93-93, I 197-93) were used as planting material and transplanted in November and harvested at the age of 13 month. Two main factors clones/variety and nutrient (N) was involved in the experiment. The unit plot size was 5m x.4m in the experiment having row to row and plant to plant distance of 100 cm and 50 cm, respectively. Results revealed that sugarcane clones and N significantly influenced yield attributes, yield and brix per cent of sugarcane. Cane yield increased up to 80% over the control due to the application of 180 kg N ha^-1. Yield production of the clones, influenced by N application followed the order: I 93-93>I 197-93>1 8-95>1 122-95>lsd 31.

Objectives:

To determine the optimum dose of N to maximize sugarcane yield.

Methodology:

Field experiment was conducted at Regional Sugarcane Research Station, Thakurgaon experimental farm located in Old Himalayan Piedmont Plain Soils (AEZ 1) of Bangladesh during 2002-2003 cropping season. The soil of the experimental site is sandy with high land having pH 5.00, low in total N (0.07 per cent), available P (11.00 ppm), K (0.15 meq %) and S (9.00 ppm). The climate of this location is sub-tropical. The experiment was laid out in a split plot design with three replications. Three budded cuttings of the studied clones/variety (one standard variety lsd 31 and four clones of I 8-95, I 122-95, I 93-93, I 197-93) were used as planting material and transplanted in November and harvested at the age of 13 month. Two main factors clones/variety and nutrient (N) was involved in the experiment. The unit plot size was 5m x.4m in the experiment having row to row and plant to plant distance of 100 cm and 50 cm, respectively. All management practices were done as and when required. Four levels of nitrogen (0, 60, 120 & 180 kg N ha^-1) as urea was applied in three splits: first as basal application (during transplantation), second at the tiller initiation stage (120 days after transplantation) and third at the grand growth phase (180 days after transplantation). Recommended doses of P, K, S and Zn- P₃₅K₁₀₀S₂₅Zn_2.5 kg ha^-1 was used for sugarcane. Full amount of triple super phosphate, one third of muriate of potash, full doses of gypsum and zinc sulphate were applied in the cane furrows and mixed thoroughly with soil. Remaining two third of muriate of potash were applied in two splits as top dressed after 90 and 180 days of transplantation. Data recorded were statistically analysed and the significance of mean difference was calculated following least significant difference (LSD) test at 5% level.

Achievement/Findings:

Results revealed that sugarcane clones and N significantly influenced yield attributes, yield and brix per cent of sugarcane. Cane yield increased up to 80% over the control due to the application of 180 kg N ha^-1. Yield production of the clones, influenced by N application followed the order: I 93-93>I 197-93>1 8-95>1 122-95>lsd 31.
