Assessment of the Slow-Release Nitrogen Foliar Fertilizer Nitamin® in Comparison to Foliar Urea and Soil-Applied Nitrogen to the Yield of Field-Grown Cotton (Gossypium Hirsutum, L.)

Effective nitrogen (N) management in cotton production is essential in order to achieve proper growth and development. However, soil-incorporated N can undergo a series of chemical conversions along with numerous loss mechanisms (leaching, volatilization and denitrification) that can make N unavailable to the plant. In addition, soil-incorporated N has faced much scrutiny over the years for its role in many detrimental environmental situations. Methods to reduce the amount of soil-applied N such as foliar fertilization have been examined and studied while simultaneously supplying the N that cotton requires. From root and vegetative growth to reproductive development, N is vital in every phase of cotton development and plant demand is high.
