Weed Management Strategies for Organic Farming of Kharif Groundnut
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2017, Vol 1, Issue 7
Abstract
A field experiment was conducted during kharif seasons of 2015 and 2016 at Junagadh (Gujarat) to study the weed management in groundnut (Arachis hypogaea L.) under organic farming. The pre-sowing (Deep ploughing, stale seedbed and soil solarization) and post-sowing (Wheat straw mulch @ 5 t/ha, hand weeding & interculturing at 15, 30 and 45 DAS, Weed-free check and Weedy check) treatments were evaluated. The results revealed that stale seedbed, followed by soil solarisation were found effective in controlling weeds and improving growth and yield attributes and ultimately pod and haulm yield over deep ploughing. Results further indicated that hand weeding & interculturing at 15, 30 & 45 DAS and wheat straw mulch @ 5 t/ha significantly suppressed weed growth and enhanced growth and yield of groundnut. Groundnut is a major crop of Saurashtra region and demand of organically produce groundnut is increasing day by day due to health conscious and premium price of organic product tempted to farmers for organic cultivation. Organic farming is a production system, which avoids or largely excludes the use of synthetically compound to maximum extent feasible. organic farming rely upon crop rotation, crop residues, animal manures, green manures, off farm wastes, mechanical cultivation, mineral bearing rocks and aspect of biological pest control to maintain soil productivity, to supply plant nutrients and to control insects, pathogens and weeds [1].
