| Abstract | ||
| The present study was conducted during the growing season of 2015/2016 in the Field of Agricultural College, Basrah University, to study the effect of two methods of sowing (rows in plot or random sowing) and spraying with salicylic acid (0, 30 and 60 mg. l-1) and their interaction on growth and yields of seed and volatile oil of local dill (Anethum graveolens L.) at a Complete Randomized Block Design in a factorial experiment with three replicates. The results analyzed with Least Significant Differences Test (L.S.D) at 0.05 level. The most important results obtained were: Plants grown at rows gave a significant increases in numbers of lateral branches, leaves number, number of inflorescences.plant-1,weight of 100 seeds, seed yield. plant-1,volatile oil percentage and volatile oil yield. plant-1, whereas plants grown from random sowing gave a significant increase in plant height . Plants sprayed with salicylic acid gave a significant increases in plant height, numbers of lateral branches, leaves number, number of inflorescences.plant-1, inflorescence-1, weight of 100 seeds, seed yield. plant-1, volatile oil percentage and volatile oil yield. plant-1. The Interactions between the studied factors showed a significant effect in some parameters, Plants grown at rows and sprayed with 30mg. l-1 gave a highest values in seed yield. plant-1and volatile oil yield. plant-1 1.773 and 1.175 gm, whereas plants grown at rows and sprayed with 60mg. l-1 gave a highest value in volatile oil percentage 0.776%. | ||
