Answer 1

During October, the day temperature should be above 26 degree Celsius which helps the ripening and bursting of cotton balls under the sunny skies. Along growing period of atleast 200 frost free days is also necessary for the plant to mature. Rainfall should be moderate, ranging between 50-75 cm. Cotton plant needs sufficient rainfall in the early stages of growth, but a sunny and dry weather is required after flowering.
