Cover crop (Trifolium alexandrinum) effects on weed seed bank
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 2
Abstract
For the purpose of determining the effects of Berseem clover(Trifolium alexandrinum L.) as a cover crop on seed bank and weed density, two experiments were performed at Bay Cola Center for Research in Neka, Iran, in randomized complete block design with two treatments and four replications during the years 2011 and 2012. Treatments consisted of cultivations both with and without a cover crop. Results showed viable seed density for all weed species was uniform in the soil in the first year. Continuing the culture of berseem clover as the cover crop had a significant effect on the weed seed bank. The amount of Johnson grass (Sorghum halepense L.) seeds in the soil decreased (as much 70%) more than any other species (average decrease = 37%). Weed density was reduced following application of the cover crop in both years. The dry weight of Black bindweed (Polygonum convolvulus L.) and Johnson grass decreased significantly after the application of the cover crop for both years. In this experiment, the use of berseem clover as a cover crop for land covering until the middle of April diminished the need for an herbicide application.
