Abstract

                                Experiments wore conducted at Cotton and Millets Experiment Station, Kovilpatti during 1980-81 to 1982-83, to study the effect of moisture conservation on the yield of seed cotton, by cultural (forming tied-ridges on 30th day of sowing) and chemical methods (use of anti transpirants). The results revealed that in the tirer year of study (1980-81) kaolin spray at 10 kg/ha on 50th and 70th day of sowing had racorded significantly higher kapas yield of 792 kg/ha over control, water spray. pruel water spray, PMA spray and cowdung slurry spray. In the other two years of study (1981-82 and 1982-83) there was no significant difference among the treatments. In all the three years of study, moisture conservation by cultural method (tying the ridges on 30th day of sowing to form micro water shed) did not produce any significant impact on yield.
