Abstract
This experiment was conducted to determine firstly the impact of method of the magnesium addition, and secondly the effect of number of times of the magnesium addition on the yield and growth of the Eggplant under greenhouse conditions. This study included two method of the magnesium addition (with irrigation water or spraying on shoot). The addition of magnesium was one or two times at the concentration of 100 mg L compared to the control treatments. The randomized complete block design was used to find the significant differences among the experimental factors. The outcome showed that the magnesium deficiency was 4.1% which noticed in the mid of the February. However, the percentage of the magnesium deficiency was 46.7% at the mid of the April. This result indicated that the plant needs more magnesium with increasing its growth. It was appeared also that the magnesium deficiency was 34.6% at two times spraying, 42.2% at one time spraying, 44% at two times irrigation and 63.4% at one time irrigation. This study concluded that the best spraying of magnesium was at two times in a well-aerated greenhouse.
