Results indicated that non-mulched treatments (DI and SI) received an average of 246 mm and 373 mm, respectively to produce 44.1 t ha−1 and 37.7 t ha−1 cucumber, respectively, whereas treatments with transparent and black plastic mulching consumed an average of 213 mm and 214 mm water, respectively and yielded average of 63.9 t ha−1 and 57.8 t ha−1. These results support those of Wien et al. (1993), who showed that increased tomato growth and yield by polyethylene mulching is a consequence of enhanced root growth and nutrient uptake early in the season.
