Abstract
In order to study the effect of different levels of irrigation and different rates of A200super absorbent on dry leaf yield of tobacco burley21, a factorial experiment with four replications was conducted in RCB, during crop season of 2010. The levels of irrigations )80, 120 and 160 mm evaporation from A pan( and four levels of super absorbent (0, 5, 10 and 15 g.m-1). Increasing irrigation interval length from 80 to 160 mm evaporation from pan decreased plant height, dry leaf yield and total income by 13, 10 and 15%, respectivly. Application of 5, 10 and 15 g.m-1 of super absorbent compared to control increased dry yield of leaf by 4, 7 and 10%, and total income by 7, 8 and 13%, respectively. Results also showed that application of 1 kg of super absorbent (costed at least 120000 toman/kg) increased total income by 2580 toman. In general, delayed irrigation decreased quantity and income of tobacco. On the other hand, application of super absorbent increased quantity, quality and income of tobacco as compared to the control treatment, since super absorbent is expensive, its application would not be economical and it is thus not recommended.
