Effect of Tillage and Irrigation Levels on Growth and Yield of Indian Mustard {Brassica juncea L.)

摘要

A field experiment was carried out during rabi season of 2014-15 to study the effect of tillage and irrigation levels on growth and yield of Indian mustard. The treatments comprised of three tillage practices (zero tillage, reduced tillage and conventional tillage) in main plots and four irrigation levels (no irrigation, one irrigation, two irrigations and three irrigations) in sub-plots with three replications. Under sandy loam condition, conventional tillage proved significantly superior in all growth attributes (plant height, crop growth rate, leaf area index and number of primary and secondary branches) and seed yield. The conventional tillagesignificantly improved the grain yield of mustard over zero tillage by 18.08% and was found statistically at par with reduced tillage. Irrigation levels, also significantly influenced all the growth attributes and seed yield. Three irrigation levels Significantly enhanced the grain yield by 46.48% over no irrigation.
