Experiment Title Effect of integrated nutrient management on cotton under high density planting system
Research Type Departmental Trail
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. Nitrogen is universally deficient in almost all the agricultural soils and cropping systems of the world so, it is important to use external nitrogen inputs to produce the crops for satisfying the ever-increasing demands of human populations. Farmers need to apply a huge amount of nitrogen fertilizer in agricultural crops because of its lower recovery (30%-50%) due to its various losses from the soil-plant system. Low recovery of N is associated with its loss by volatilization, leaching, surface runoff, de-nitrification and plant canopy. To maintain the long-term sustainability of agriculture, effective and efficient approaches to slow the removal and returning nutrients into the soil is required. The overall strategy for increasing crop yields and sustaining them at a high level must, therefore, include an integrated approach to the management of soil nutrients, along with other complementary measures. In this case, it is attempted to discuss several works done on this approach with deep emphasizing on the role of integrated nutrient management in enhancing nitrogen use efficiency to achieve sustainable agricultural production in annual crops. Hence, in this review, the present investigation was designed and conducted to find out optimum integrated nutrient management on yield potential of cotton under high density planting system.  To assess the effect of integrated nutrient management on growth and yield of cotton under HDPS  To find out the effect of integrated nutrient management on content and uptake of nutrient by cotton  To study the effect of integrated nutrient management on soil chemical properties
