| Abstract | ||
| The experiment agent was done by Nested Combined Design using RCBD in the field of Horticulture and Landscaping Dept., Faculty of Agric., University of Diyala at spring season 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 l-1 symbolized as S0, S1, S2 and S3 respectively). Salicylic acid was sprayed on two batches, the first after a month and the second after two months after of seedlings transplanting. The differences between the averages was tested by polynomial Duncan test at the 0.05 level of significance. The result of this study showed the using of shading level 35% gave superior increasing in plants yield and total yield which was 1.342 kg plant -1 and 52.614 kg respectively, while 65% shading level was significantly increase fruit size, which did not differs from the 35 % shading level (103.00 and 100.25). Control treatment was significantly increase fruit's number. Spraying of salicylic acid achieved significant increasing in all traits as compared with control treatment, the highest results with 75 mg l-1. Interaction between shading and salicylic acid gave significant effect of all traits especially of plant yield and total yield. Shading of 35% and salicylic acid at 75 mg l-1 gave best results. | ||
