Abstract/ Executive Summary:

Strategies to reduce the time from cotton planting to crop harvesting were examined in a system approach at three farms of Cotton Development Board located in Sreepur, Gazipur; Sadarpur, Dinajpur and Jagadishpur, Jessore during 2002-2003 growing period. Two earliness systems viz. management for earliness and early variety were compared against commercial management strategies. Results revealed that full season cultivar responded better to the earliness management system than early genotype.

Location: Sreepur, Gazipur; Sadarpur, Dinajpur and Jagadishpur, Jessore

Start Date: 00-00-2002

End Date: 00-00-2003

Program Area: Crop-Soil-Water Management

Commodity: Cotton

Objectives:

The study was undertaken to examine interdisciplinary factors in one experiment for achieving earliness.

Methodology:

An experiment was conducted at three research farms of Cotton Development Board located at Sreepur, Gazipur; Sadarpur, Dinajpur and Jagadishpur, Jessore in 2002-2003 growing period to examine the 3 different management packages against standard management packages in achieving earliness. The treatments were: A. Standard management: full season cultivar (CB-9), farm standard nitrogen, standard insect management and standard irrigation timing for last irrigation. B. Early cultivar- short duration genotype (BC-0397), farm standard nitrogen, standard insect management and standard irrigation timing for last irrigation. C. Early management 1: full season cultivar (CB-9), reduced nitrogen, standard insect management and omitting last irrigation timing. D. Early management 2: short duration genotype (BC-0397), reduced nitrogen, standard insect management and omitting last irrigation timing. In case of standard nitrogen, 250 kg/ha Urea was applied at 4 equal split in basal, 3 weeks after sowing, 6 weeks after sowing and 9 weeks after sowing. In case of reduced nitrogen, last split was omitted. Because of rainfall pattern, irrigation timing was not altered for any treatments. Unit plot size was 10m × 10m. All other management practices were equal for all treatments. Seed cotton yield and yield contributing data were recorded from the middle rows leaving of 2 border rows at both side. Analysis of variance was done by MSTAT using location as replicates.

Achievement/Findings:

Harvesting time of full season cultivar CB-9 was 10 days early in earliness management system and the yield difference was not significant. In case of early genotype BC-0397, earliness achieved for 4 days through management with significant reduction in seed cotton yield.
