Abstract

A field experiment was conducted to evaluate the effect of mulch and planting date in integrating with herbicide application for weed control in lentil. The experiment was in a split-split plot arrangement with three replication at the research farm of University of Tehran in fall of 2016 and spring of 2017. The spring and fall planting dates were main plots, mulch types (secale, barley, no mulch (Control)), and herbicides (trifluralin, imazethapyr, pyridate) were assigned to subplots and sub-sub plots, respectively. Galium aparine, Amaranthus retroflexus and Chenopodium album had the highest population among the weed species present in the field. The average weed population in mulches was significantly lower than bared soil. In the fall planting date, the weed biomass was averagely 40% lower than in spring planting time. In the fall planting, imazethapyr was found the most efficient herbicide, while in spring planting, pyridate and imazethapyr herbicides showed similar efficiency. Generally, fall planting date produced 50% more yield than spring planting. The treatment of secale mulch result in improved yield by 56% as compared to no mulch (control). Besides, pyridate herbicide increased the total yield by 68% as compared to control. It would be better to use the secale mulch followed by hand-weeding, if cheap working force are available. Otherwise the application of imazethapyr and secale mulch was the best option for weed control in lentil.
