Water is one of the primary inputs in agricultural production. This vital resource is becoming a scarce commodity day by day; therefore it requires planning, developing & managing with utmost care. Drip irrigation with higher water application and distribution efficiencies, is gaining ground in horticulture as well as cash crops. It meets the crop water requirements in an optimum way. Analyzing the hydraulics of drip irrigation system is necessary in order to study the dynamics of wetting front advance in the soil and the crop root zone. Use of mulches with drip irrigation system is added advantage to save the precious irrigation water and to lower the weed infestation in the field. Mulches act as a barrier between the atmosphere and the soil surface and restrict evaporation. This book provides a scientific approach to the study of different hydraulic parameters of drip irrigation system, effect of different mulches on soil temperature and crop yield and cost economics of drip irrigation system for production of bottle gourd. The book will be highly useful to the research scholars, academicians and farming community.
