| 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 three sowing dates of Local Corundum plant (Coriandrum sativum L.) i.e 10, 20, 3010 and spraying with salicylic acid 0, 35 and 70 mg. l-1and their interaction on growth and yields of seed and volatile oil at a Complete Randomized Block Design in a factorial experiment with three replicates. The results analyses with Least Significant Differences Test (L.S.D) at 0.05 level. The most important results obtained were:- Plants sown on 20/10 gave a significant increase in plant height, fresh and dry weight of vegetative growth. plant-1 , whereas plants sown on 10/10 gave a significant increases in weight of 100 seeds, seed yield. plant-1, volatile oil yield. plant-1( 1.173, 4.163 and 2.733 g) and potassium content, while plants sowed on 30/10 gave a significant increases in leaves content of nitrogen and phosphorus. Plants sprayed with salicylic acid gave a significant increases in dry weight of vegetative growth, number of inflorescences.plant-1, seeds number. inflorescence-1, weight of 100 seeds, seed yield. plant-1, volatile oil percentage, volatile oil yield. plant-1, the effect increases as the concentration increased, the highest values were 18.0 seed, 1.143, 4.481g, 0.763%, 3.366g, as well as leaves content of nitrogen, phosphorus and potassium. The Interactions between the studied factors, showed a significant effect only in weight of 100 seeds and volatile oil yield. plant-1. | ||
