THE EFFECT OF SHADING AND SPRAYING SALICYLIC ACID IN 2- HOIDS TOMATO RECIPES BY USING VERTICAI WAY OF TRAINING METHOD

Abstract

The experiment agent was done by design Complete Randomized sectors RCBD in horticulture and engineering department field Alhaddaiq-Faculty of Agriculture - University of Diyala season spring 2015 to study the impact of global shading and spraying Salicylic acid in some tomato harvest quotient. It included three levels of shading (without shading 0% and 35% and 65%) have a code symbols (L0 and L1 and L2) using over foods to cover and four of Salicylic acid concentrations (0, 75, 150, 225) mg letter -1 her (S0, S1, S2 and S3) sprayed on the first two installments after a month and the second two months after planting seedlings. We tested the differences between the averages by polynomial Duncan test at the 0.05 level of significance. The result of this study appeared the using of shading by 35% lead to outweigh the moral in recipes holds one plant overall and winning because of full (1.342 kg plant -1, 52.614 kg H-1), respectively, while outperforming the treatment of shading 65% morally in the character of the size of the fruit, which did not morally different from the treatment of shading, amounting to 35% (103.00, 100.25) and 3 cm higher than the comparison treatment in a number of fruits recipe on my paperwork shading. Spraying Salicylic acid turn achieved a significant increase in all of the traits on the treatment of comparison was the highest increase for spraying a concentration of 75 mg letter -1. The overlapping was of the significant differences among the treatments for all of the traits, and it was best to overlap the adjectives holds one plant overall and winning is among the 35% shading and spraying the treatment level of 75mg letter1-.
