Abstract
Considering the lack of water problems in the country, the optimal use of water consumption in agriculture is important and significant. Among the solutions that can deal with the negative effects of lack of water is adding some additives to the soil. Therefore, in order to investigate the effect of sawdust compost and water stress on yield and yield components of greenhouse tomato, an experiment was conducted in the form of a completely randomized design with four replications. The main factor was moisture stress (I), which included treatments without stress (control) and available water depletion at the rate of 30% (I1), (I2) 65%, (I3) 75% and (I4) 85%, and the secondary factor was mixing ratios. Sawdust compost (C) in levels without sawdust compost (C1), and mixing 5 (C2), 10 (C3), 15 (C4) and 20 (C5) percent by volume.The results showed that irrigation had a significant effect on the yield and its components, except the length of the stem. Also, the effect of sawdust compost, as well as the mutual effect of irrigation and sawdust compost on yield and yield components, was significant at the five percent level based on Duncan's multi-range test. It was observed that the maximum value of the average yield and number of fruits was related to the treatment of I1C3 at the rate of 254 (grams per pot) and I1C4 at the rate of 13.5 (fruits per pot).
