Effect of Integrated Weed Management and Balanced Fertilization on Crop Weeds Competition in Coriander (Coriandrum Sativum L.)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
field experiment was conducted at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan), during 2002-03 and 2003-04. Pooled analysis of data indicated that all weed management practices significantly reduced the weed density and weed dry matter at all stages of crop growth period and improve yields (seed and straw yield) of crop as compared to control. Two HW at 30 and 45 DAS resulted in maximum reduction in weed density and dry matter and gave the highest seed (15.84 q/ha) and straw yield (25.27 q/ha) of coriander. However, this treatment was found at par with pendimethalin 1.0 kg/ha + one hand weeding at 45 DAS in reduction of weed dry matter and improving crop yields. Balanced fertilization with 60 kg N+ 30 kg P+ 30 kg K + 30 kg S/ha significantly improved weed dry matter over N+P and N+P+K application but also significantly improved crop yields. However, all fertilization treatments fail to affect weed density significantly.
