Experiment Background
|
Cotton (Gossypium hirsutumL.) is the major fibre and cash crop, not only in India but for the entire world. It is a crop of global significance playing a significant role in the agricultural and industrial economy. Around 60% of fibre to Indian textiles is from cotton. Cotton is commonly known as “White gold” and “King of natural fibre” owing to its higher economical value amid the cash crops.
Plant growth retardants are natural or synthetic organic compounds that control or modify one or more physiological events in plants. Synthetic compounds are widely used in cotton, for reducing plant height. The plant growth retardants affect many physiological functions in plants. Cotton producers and researchers have, therefore, used plant growth retardants as a means to manage the balance between vegetative and reproductive growth for efficient cotton production. But research on application of growth retardants in conjunction high density planting will pave way for synchronized maturity of the crop with uniform plant height that may help in harvesting of seed cotton mechanically at large scale level. Hence, the present investigation was designed and conducted to find out optimum crop geometry and to know the yield potential of cotton under high density planting system.
