Winter wheat yield and soil physical properties responses to different tillage and irrigation
Journal Title: European Journal of Biological Research - Year 2016, Vol 6, Issue 1
Abstract
Adopting a better tillage system not only improves the soil properties and crop productivity but also improves water use efficiency. A field experiment was conducted over 2 years in Norman E Borlaug Crop Research Centre of the Govind Ballabh Pant University of Agriculture and Technology, Pantna-gar region of Uttarakhand, India to determine the effect of tillage systems and irrigation treatments on soil physical properties and yield of winter wheat (Triticum aestivum L.). Plots having conventional tillage along with frequent irrigation showed higher values of saturated hydraulic conductivity while zero tillage gaves the higher values of bulk density, mean weight diameter, plant available water capacity, effective porosity and soil organic carbon. Wheat yield was not significantly affected by tillage practices. There was a significant increase in wheat yield in the plots under I4 over I1 and water use efficiency between irrigation treatments was also significantly different. Hence, for wheat crop in a sandy loam soil of the Uttarakhand, farmers may adopt CT with four irrigations to achieve maximum yield. This information is important for farmers from the point of view of increasing production and profitability.
