ABSTRACT
Water resources in India are found to be getting deteriorated in terms of quality as well as quantity. Mark et al. [2] reported that by the year 2025 A.D., 33% of population in India will live under absolute water scarcity condition. The per capita water availability in terms of average utilizable water resources in the country was 6,008 cubic meters in 1947 and is expected to dwindle to 760 cubic meters by 2025 [1]. Water is a major input in agriculture. The water use efficiency of the crops has to be increased in order to reduce the water loss from the fields. With drip fertigation, nutrient use efficiency is increased and the loss of nutrients to the ground water is reduced. Soluble chemicals and nutrients move with the wetting front. Hence a precise scheduling of irrigation and fertilizer applications is essential for sustainable crop production.
