Abstract/ Executive Summary:

A field study was conducted to evaluate the efficacy of northern organic fertilizer on sugarcane yield and economic return at Ishurdi (High Ganges River Flood Plain) and Thakurgaon (Old Himalayan Piedmont Plain) sites in Bangladesh. Results revealed that the combined use of northern organic fertilizer @ 750 kg per hectare and 75 per cent recommended inorganic fertilizers gave higher average sugarcane yield of 72.33 tones and the highest net economic benefit of Taka 27653 per hectare with benefit cost ratio of 1:52 from the sites under study. The average yield increase from that was 142.4 per cent over control and 4.7 per cent over recommended inorganic fertilizer alone.

Keywords: Efficacy, Northern organic fertiliser, Sustainable; Sugarcane, Production

Location: Ishurdi under High Ganges River Flood Plain and Thakurgaon under Old Himalayan Piedmont Plain soils of Bangladesh.

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Organic fertilizer, Sugarcane

Objectives:

To evaluate the efficacy of northern organic fertilizer on sugarcane yield.
To study the productivity and profitability of northern organic fertilizer for sustainable sugarcane production.

Methodology:

A field study was conducted in two sites at Ishurdi under High Ganges River Flood Plain and Thakurgaon under Old Himalayan Piedmont Plain soils of Bangladesh. It was laid out in randomized complete block design with four replications. The treatment wise different rates of organic and inorganic fertilizer at two sites are presented. The unit plot size was 8 m x 6 m. Five treatments were included in the study. They were as follows: T₁: Control (no fertilizer), T₂: Recommended fertilizer dose (RFD) as per Bangladesh Sugarcane Research Institute Guide'98, T₃: Northern organic fertilizer @ 7S0 kg /ha + 50% RFD, T₄: Northern organic fertilizer @ 750 kg /ha + 75% RFD and T₅: Northern organic fertilizer @ 750kg/ha + 100% RFD. It was planted in early December 2005 and was harvested after full maturity of the crop in January 2007. Three budded setts of Isd 34 were used as test material. N as urea and K as muriate of potash were applied in three equal splits, first at 20-30 days after transplanting, second at peak tillering stage and finally after one month of second top dressing. Full amount of triple super phosphate, gypsum, zinc sulphate, magnesium oxide and northern organic fertilizer were applied in the trenches and mixed thoroughly with soil by spade. All the recommended cultural management practices were followed as and when required. The major nutrient contents of northern organic fertilizer are given. Initial and post harvest soils at the depth of 0-15 cm were collected and analysed following standard procedure. Necessary data were recorded and analysed using the Least Significant Difference Test (LSD) at P=0.05. Cost and return analysis of different treatments were calculated on the basis of prevailing market prices during the study period.

Achievement/Findings:

It may be concluded that the integrated application with 75 per cent recommended inorganic fertilizers and northern organic fertilizer at 750 kg per hectare confirmed higher average sugarcane yield of 72.33 tones with the highest net economic benefit of Taka 27653 per hectare with benefit cost ratio of 1.52 at the sites under study. The average yield increase from that was 142.4 per cent over control and 4.7 per cent over recommended inorganic fertilizer alone. Thus, the combined application with northern organic fertilizer and 75 per cent recommended inorganic fertilizer would be cost effective for sustainable sugarcane yield and soil fertility in the study locations.
