Effect of Different Dose of Chlormequat on Growth and Yield of Okra (Abelmoschus esculentus L.)

A field trial was conducted during Kharif season 2022-23 at the sharadhey Bhagwati singh research farm of Chandra Bhanu Gupta Agriculture P. G. College, B. K. T. Lucknow  to find out the “Effect of different dose  of chlormequat on growth and yield of okra (Abelmoschus esculentus L.)” .The experiment consisted of 6 treatments concentration of chlormequat (water spray, 250, 500, 750, 1000 and 1250 ppm) replicated three times. Results revealed that   growth parameter like days to reproductive phase, number of leaf  per plant, number of branches per plant and yield attributes i.e. fruit length, fruit girth, number of fruit per plant, and yield per plant was significantly  highest with chlormequat spray T₆ (@1250ppm) as compared to rest of the treatment. However, the plant height and days to first floral initiation was significantly reduced with increasing dose of chlormequat and being highest with control. The highest fruit yield (110.22q/ha) was recorded in T₆ treatment, which was at par with T₅ (102.22 q/ha). whereas the lowest fruit yield hectare was recorded in T₁ i.e. control (53.76 q /ha) . The percent increase in yield due to chlormequat @ 1250 ppm was recorded to the tune of 7.78, 27.02, 47.90, 74.37 and 105.02 over dose of 1000 ppm, 750 ppm, 500 ppm, 250 ppm and no chloremequet spray treatments, respectively.
