Comparison of Zero Tillage and Conventional Methods of Wheat Sowing under Critical (0-1.5 m), Moderate (1.5-3.0 m) and Safe (>3.0 m) Water Table Depths

摘要

From the field trials conducted at different locations during 2001-03 on the comparison of zero-till and conventional method of sowing on wheat crop under critical, moderate and safe water table depth revealed that yield and growth attributes (germination, plant height, tillering, ear length, grains per ear, 1000-grain weight and grain yield) were better under zero-tillage sowing practice than under conventional practice. The values of seven attributes under zero-tillage were, respectively, 19.0, 4.2,14.7, 3.2,12.2, 6.7 and 6.0% higher than those under conventional practices.
