Impacts of Nitrogen Fertilizer Application and Mulching on the Morpho-Physiological and Yield-Related Traits in Cotton

Cotton is a global cash crop with significant contribution in the world economy. Optimum nutrient and water supply are most important for sustainable cotton production under warmer dry environments. Field experiments were carried out to evaluate cumulative impacts of various nitrogen doses mulches on semi-arid conditions during 2018 2019. Four doses; 0, 70, 140, 210 kg ha−1 three types mulch: control (without mulch), natural mulch (5 tons/ha wheat straw), chemical (methanol (30%). Nitrogen mulching increased 40.5% gunning turn, 30.0% fiber length, 31.7% strength, 32.6% fineness, 20.8% uniformity, 34.0% elongation. Shoot nitrogen, phosphorous, potassium, calcium, magnesium contents maximum where was applied. Natural reduced soil temperature as compared no conditions. The 0.5 1.8 ℃ lower treatments control. Maximum economic yield around 90% higher application. It concluded that optimum application not only enhanced plant growth development but also induced sustainability quality
