Abstract

From these investigation I have been reviewed different conclusions raised by investigators depend on deferent parameters and irrigation method. From the study the parameter taken under consideration are crop morphological characters (plant height, stem girth, cobs, fruit per plant, and leaves per plant e.tc), yield (kgha -1 ), water productivity (kgha -1 ) and water use efficiency. The study applies different irrigation method to compare its crop morphological characters (plant height, stem girth, cobs, fruit per plant, and leaves per plant e.tc), yield (kgha -1 ), water productivity (kgha -1 ) and water use efficiency these irrigation method are convention surface irrigation, furrow irrigation, double ridge furrow irrigation, sprinkler irrigation, surface drip irrigation (SDI), subsurface drip irrigation (SSDI) and drip irrigation under different pipeline. In these literature I have been recommend than first yield and growth parameters of the crop depend on the fertility of the soil, chemical fertilizer and physical properties of the rather than irrigation method, therefore, the researchers should be consider these factors. Secondly Water productivity and water use efficiency also depend on soil physical properties, environmental condition, and conveyance system of irrigation and cropping season in addition to irrigation method.

Highlights

Agriculture sector is projected to increase production over the years which will have need of more water resources for irrigation (Sauer et al, 2010)
The study shown that, for the selected vegetables, adoption of drip irrigation improved the yields in www.iiste.org the range of 38.2 to 65.8 % over furrow irrigation with highest yield increase in case of pea (65.8%) and tomato
The study results indicated that the drip and micro sprinkler irrigation systems saved 38 and 26 percent of water over conventional practice (Table 5).The water productivity is the ratio between the productions per unit of water applied

Summary

Introduction

Agriculture sector is projected to increase production over the years which will have need of more water resources for irrigation (Sauer et al, 2010). Fresh water availability varies around the world making water scarcity a regional, local, and global issue (Rosegrant, 1997). The efficiency of water used for agriculture globally is relatively low with over 50% of the water being lost (Bittelli, 2010). North America and Latin America have the highest amount of water available unlike other countries including Africa, Asia, and Europe where water scarcity is a growing problem (Rosegrant, 1997). By the year 2025, scientist predict that there will be 46 to 52 countries that will not have a sufficient amount of water resources available (Rosegrant, 1997). Efficient water management is a critical factor to maintain a successful crop production system. Over irrigating has negative environmental impacts including the leaching of nutrients into groundwater, loss of soil by erosion into rivers and streams and eventually finding its way to the ocean (Brady and Weil, 2010), and a waste of precious fresh water resources
