Abstract:

Present investigation on estimation of yield losses due to major sucking pests of the Bt cotton was carried out on the College Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during Kharif season of the year 2011-12. The Bt hybrid cotton cultivar KDCHH-441 was grown with the plot size of 24 m X 20 m at spacing of 120 cm x 45 cm. The data revealed that significantly higher seed cotton yield 2038.82 kg/ha was recorded from protected plots, while the yield of 1312.70 kg/ha was recorded from unprotected plots. The yield increased in protected plots over unprotected plots was 726.12 kg/ha. This showed 55.31 per cent increase in yield and 35.61 per cent avoidable loss. The result clearly indicated that by providing protection with effective pesticides against cotton sucking pests, 726.12 kg/ha yield loss can be saved. Total avoidable yield loss could be worked out as 35.61 per cent.
