An experiment was conducted at Agronomy Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar during rabi season of 2016-17 to study the effect of weed and nitrogen management in coriander (Coriandrum sativum L.). The experiment evaluated in Randomized block design with factorial concept and replicated three times. Results show that the significantly lower weed count at 40 (0.71m-2) and 60 (0.71m-2) DAS, dry weight of weeds (0.00 kg ha-1) and weed index (0%). Whereas, the significantly higher weed control efficiency (100%), superior growth parameters, yield attributes and higher seed (1055 kg ha-1) and straw (1688 kg ha-1) yield were recorded under weed free (W2) and was at par with pre emergence application of pendimethalin 1 kg ha-1 + interculturing followed by HW at 30 days after sowing (W6). The application of 60 kg N ha-1 (N3) recorded significantly higher values of growth parameters, yield attributes and maximum seed (849 kg ha-1) and straw (1373 kg ha-1) yield and was at par with 40 kg N ha-1 (N2). Weed count and dry weight of weeds increased significantly with each increase in nitrogen levels from 20 to 60 kg N/ha. But number of weeds per m2 was not influenced by different nitrogen levels. Whereas, the plant population and harvest index was not remarkably influenced by both weed management practices and nitrogen levels. This study revealed that, efficient weed management and remunerative higher yield of coriander can be obtained by adopting integrated weed management approach i.e., application of pendimethalin 1 kg ha-1 as pre emergence + interculturing followed by hand weeding at 30 DAS along with application of 40 kg N ha-1 under North Gujarat Agro-climatic condition.
