ABSTRACT
In today’s world, where water resources are scarce in many regions, the irrigation industry is under pressure to improve water use efficiency and reduce environmental impacts. Drip irrigation is a very efficient irrigation method possessing potential to improve irrigation performance. Drip involves application of water drop by drop through closed network of plastic pipes at frequent intervals near to the root zone for consumptive use of the crop. Drip irrigation added with fertilizer, fertigation reduces the wastage of water and chemical fertilizers especially nitrogenous and subsequently optimizes the nutrient use by supplying them at critical stages, proper place and time, which finally increase water and nutrient utilization. Throughout the world, emphasis is being given for efficient utilization of harvested rain water by reducing deep percolation losses and maximizing benefits from the use of available water resources for sustainable crop production. One such popular way is to change the traditional flood irrigation method to most efficient micro irrigation methods like drip irrigation. In practice most of the studies are based on IW/CPE approach on the basis of which levels of irrigation are set. The effect of different levels of irrigation on morphology, growth, yield parameters and water use efficiency are studied. Also, in various studies comparison has been made between drip fertigation and broadcast fertilizer application without the use of drip and it is concluded that fertigated crops have shown promising results in growth, yield and quality parameters than traditional methods of fertilizer application. The results have shown that drip irrigation out performs the traditional methods in all aspects of crop production.
Key words: Drip irrigation, Fertigation, IW/CPE, Water use efficiency.
