Effect of Integrated Weed Management and Balanced Fertilization on Weed Dynamics in Coriander (Coriandrum Sativum L)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 6
Abstract
A field experiment was conducted at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) to determine the weed dynamics, in coriander and their effect on seed yield. Pooled analysis of two year data indicated that, among eight weed species reported in the field Chenopodium murale, Spergula arvensis and Cyperus rotundus were found most, dominating weed species and comprises more than 50 percent of total weeds, at all stages of crop growth. All weed management practices significantly reduced the density and dry matter of all weed species and improve the weed control efficiency and seed yield of coriander, as compared to control. Two HW at 30 and 45 DAS resulted in maximum reduction, in weed density and dry matter, and resulted in highest seed yield (15.84 q/ha) of coriander. However, at par seed yield was obtained by another treatment of pendimethalin 1.0 kg/ha + one hand weeding at 45 DAS. Both the treatments also remained, at par in reduction of weed dry matter and resulted in maximum weed control efficiency, as compared to rest of practices. Balanced fertilization with 60 kg N+ 30 kg P+ 30 kg K + 30 kg S/ha also significantly improved weed dry matter, but also simultaneously enhanced the seed yield of coriander, over N+P and N+P+K application. Interactive effect of weed management and balanced fertilization was also found significant, in respect of monocot weed dry matter, at 90 DAS and seed yield of coriander. A pre-emergence application pendimethalin 1.0 kg/ha, followed by one HW at 45 DAS and fertilization with 60 kg N + 30 kg P2O5 + 30 kg K2O + 30 kg S/ha, would be recommended to achieve maximum weed control efficiency and higher seed yield, from coriander cultivation.
