Evaluation of Integrating Mechanical and Chemical Methods of Weeds Control on Yield and Yield Components of Corn (Zea Mays L.)
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 4
Abstract
Use of efficient methods of weed control with as regards environmental sustainability as well as increased crop yield and also weed resistance to herbicides is essential. In order to, an experiment was conducted in 2012 in the Damavand jaban in Iran. Experiment treatments were compared in a split plot design by a randomized completely block design with 3 replication. The used variety of maize was S.C. 301. Main factors included 3 levels of cultivation, once, twice and without cultivation. Sub factors were weed control by application of indicated herbicide in 5 levels: cruz herbicide , 2-4.D herbicide and their combined (cruz +2-4.D) in the rate of complete(in order 2 and 1.5 lit/hec) , low- dose (%75complete dose)and no weed control. The results the highest of weed control and with followed the highest yield by ranged 15.47 ton per hectare related to cruz +2-4.D (complete dose) + twice cultivation treatment and lowest yield by ranged 10.56 ton per hectare related to Weedy + non cultivation treatment.
