Abstract
A field experiment was conducted in private field in Kerbala governorate to investigate the response of two species of basil plant to foliar spray with methionine and salicylic acid in growth and yield components during the growing seasons of 2013-2014 and 2014-2015. A Spilt- Plot Design within RCBD was adopted in three replicates . Ocimum kilimandsharicum and the local Ocimum basillicum species were planted in main plots. The second factor was the foliar spray at three levels of Methionine (0 ,100 and 200 mg.L-1) which were distributed in the sub- plots and the third factor, foliar spray with salicylic acid at three level (0,50 and 100 mg.L-1 ) which were also distributed in sub-plots. The Data were statistically analyzed using SAS and the means were compared with LSD at 5%. Results showed a significant influences of the interaction between the experimental factors on the highest of plants, the number of branches, leaf area, the total fresh and dry yield and leaf content of NPK. Local species was significantly superior to the Ocimum killimandscharicum L. in the vegetative characters ( plant height, leaf area, shoot fresh and dry weight, total fresh and dry yield per unit area, and the percentage of shoot dry matter for the both seasons . Foliar spraying with methionine at a concentration of 100mg.L-1 significantly effected on the number of main branches in the first season only and spraying at a concentration of 200 mg.L-1 effected in the leaf area on both seasons . Foliar spray with salicylic acid at a concentration100 mg.L-1 significantly effected on the leaf area for both seasons and also effected on the total fresh yield per unit area in second season only. The interaction between the three factors significantly effected in the vegetative characters . As well as the local species significantly gave the highest total fresh yield per unit area i.e. 24.63 ton.ha-1 when the sprayed with methionine at a concentration 200mg.L-1 and salicylic acid at a concentration of 100mg.L-1 while the lowest total fresh yield i.e. 4.69 ton.ha-1 was produced by the foreign species when the sprayed with methionine at a concentration of 200mg.L-1 and salicylic acid at a concentration of 50mg.L-1.The local species gave significantly the highest total fresh yield i.e. 39.84 ton.ha-1 when the plants sprayed with methionine at a concentration of 200 mg.L-1 and salicylic acid at a concentration of 50 mg.L-1in the second season as compared with the lowest yield i.e. 10.11ton.ha-1 produced by the foreign species when sprayed with methionine at a concentration of 100mg.L-1 and distilled water.
