Wheat Productivity, Land and Water Use Efficiency by Traditional and Laser Land-leveling Techniques
Abstract:
Present study was conducted to determine the impact of laser land leveling versus traditional land leveling on wheat productivity, land and water-use efficiency during Rabi 2000-2001. The result indicated that Laser land leveling gave significantly higher grain yields (5.56 t ha-1) than the unleveled land (3.99 t ha-1) but was at par with traditionally leveled one. However, no significant differences among the treatments were recorded for 1000-grain weight and grains ear-1. The total irrigation duration and applied water depth was reduced by 47 and 15% as compared to unleveled and traditional leveled fields, respectively. The laser-leveled fields exhibited the highest water use efficiency (WUE), which was 98.7 and 29.36% higher than the unleveled and traditionally leveled field, respectively. It was concluded that the use of Laser Land leveling surely increases grain yield and save irrigation water as compared to traditional method of sowing.
