Integrated Weed management in Perennial Alfalfa (Medicago Sativa L.) and theirs effects on soil's micro fauna
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 4
Abstract
A research was conducted in perennial alfalfa to study the effects of integrated weed management on hay, alfalfa's density and alfalfa height and soil's micro fauna (mites)as well as. This study was implemented in the randomized complete block design in Amzajerd village alfalfa farms (located seven kms from Hamedan-Tehran road) during the summer and autumn, 2010. Ten treatments in four replications were considered which were included in five levels and combination treatments in five levels, too. The time of using treatments included: Dactal herbicide: After growth of weeds, Naboes herbicide: In step 2 to 5 levels of weeds, Pursuit herbicide: soon after the growth of weeds. Flamethrower treatment was used ten days after the first harvest of alfalfa. In combination methods, flamethrower treatment was used before using the herbicide treatments. After %50 of flowering of alfalfas, selection of sample was performed by quadrate area in 50×50 cm and quality and quantity were measured for Alfalfa that includes: Dry weight, height and density. Most treatments to addition the Alfalfa density were conducted by Naboes herbicide treatment. Naboes combination treatment with the flamethrower was the best option for dry weight addition of Alfalfa. Naboes herbicide left the highest height of the Alfalfa. The integrated treatment "Naboes with flamethrower" was best option for having highest soil's microphone.
