Abstract

Water scarcity is one of the main problems to be challenged by the world. Improper management has contributed extensively to the current water scarcity and is also a serious challenge to future food security and environmental sustainability. During the hot summer days (May–August), high soil temperature accelerates evaporation at soil surface and reduces soil moisture, with a consequent negative impact on the growth and development of the crop. For satisfactory yield, it is necessary to conserve soil moisture and modify soil temperature for the cultivation of cotton. A field experiments were conducted consecutively for two years during kharif season of 2019 and 2020 at Instructional Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner. The experiment comprising total 20 treatment combinations; five level of irrigation (0.30 PE, 0.45 PE, 0.60 PE, 0.75 PE and 0.75 IW/CPE ratio) and four mulches (no mulch, dust mulch, straw mulch and polythene mulch)
