Abstract/ Executive Summary:

An experiment was conducted at Bangladesh Sugarcane Research Institute, Ishurdi, Pabna, during the cropping season 2011-12 to find out optimum water requirement for three different sugarcane clones and one variety as well as to determine the response of clones at different stages (five irrigation treatments) to irrigation. Maximum yield was found 114 tha-1 at treatment I2 where irrigation was applied 2 nos and it was irrigation application only for establishment. Maximum pol% was found 11.88 at treatment I4 where irrigation was applied 4 nos and it was irrigation application up to last tillering stage. Highest yield, 126 tha-1 was found from vrriety V4 ( Isd 37) and highest Pol % Cane (12.41) was found from clone C1 ( I 39-04).

Keywords: Sugarcane, Irrigation, Yield, Water

Location: Bangladesh Sugarcane Research Institute(BSRI), Ishurdi, Pabna

Start Date: 01-11-2011

End Date: 30-11-12

Program Area: Crop-Soil-Water Management

Commodity: Sugarcane

Objectives:

(i) To find out optimum water requirement for different agro ecological zone

(ii) To determine the optimum stage of sugarcane to irrigate based on weather and soil where the crop shows best performances

(iii) To determine yield, yield components, draught sensitivity and water use efficiency subject to water stress

Methodology:

The developing sugarcane varieties or promising clones was planted in conventional method. The experiment was in split plot design with two factors and three replications: Factor A: Irrigation: I0 = No Irrigation (Rainfed condition) I1 = Irrigation at plantation period (1- 30 DAP) I2 = I1 + Irrigation at establishment period (30-60 DAP) I3 = I1 + Irrigation at early tillering stage (90-120 DAP) I4 = I1 + Irrigation at late tillering stage (120-150 DAP) (Depth of each irrigation would be fixed up as per soil classification and field capacity) Factor B: Sugarcane Clones: C1 = I 39-04 C2 = I 152-04 C3 = I 06-04 V3 = Isd 37 Plot size : 8m x 6m

Budget: 50000/-

Total Budget (Tk.) : 50000/-

Achievement/Findings:

Sugarcane yield and yield contributing parameters were varied significantly under different irrigation treatment as well as for different variety. Yield varied from 71.32 t ha -1 to 114.0 t ha -1 due to different irrigation treatment. Lowest yield was found 71.32 t ha -1 from treatment I0 where no irrigation was applied (Rain fed) where as the highest yield (114.0 t ha -1) was obtained from the treatment I2 where irrigation was applied 2 nos and it was irrigation application up to establishment period. Pol % of cane was highest (11.88) from treatment I4 (4 irrigation at one month interval).The highest yield, 126 tha-1 was found from vrriety V4 which was Isd 37 and highest Pol % Cane (12.41) was found from clone C1 ( I 39-04).
