Effect of Irrigation Regimes and Training Method on Yield and Quality of Tomatoes Marmande cultivar

The experiment was performed as a factorial based on a completely randomized block design with 3 replications in the research farm of Ilam University in cropping year of 2016-2017. The irrigation levels including 80, 100, 120 and 140 percentages of the plant water requirement were assigned to the main plots and the two plant training systems including uprighting trunk and layering were assigned to the subplots. The results showed that increasing the amount of irrigation water (140%) lead to increase in tomatoes (Solanum lycopersicum L.) yield and its important components. In addition, the highest yield, fruit size and number of plant in the each experimental unit were recorded in uprighting trunk method. Generally, using uprighting trunk method in combination with irrigation treatment including 120% plant water requirement was found best to improving yield and quality of tomato Marmande cultivar. Therefore, these treatments are suggested for increasing the yield and improving the quality of Marmande cultivar of tomato in climatic conditions of Ilam area.
