| Abstract | ||||
| Two field experiments were carried out at the Agricultural Experimental Station of National Research Centre at Shalakan, Kalubia Governorate during 2001 and 2002 seasons to study the single and combined effects of soil moisture stress (Skipping one irrigation either at vegetative growth, flowering or pod formation stage i.e. 30, 45 and 60 days from sowing, respectively) and foliar application of micronutrients compound amino (0, 0.5, 1 and 1.5 L/fed.) on growth, yield and its related characters as well as the seed chemical composition of mung bean (cv. Kawmy-1). The results revealed that skipping one irrigation at any of the three studied stages significantly reduced growth criteria, seed yield and its components as compared with the control plants. However, the negative response of mung bean plants to skipping one irrigation was more pronounced at pod formation stage than other two stages. Moreover, the exposure to water stress significantly increased the protein content in mung bean seeds, whereas an inverse relationship was noticed as for the percentage of total carbohydrate in the produced seeds, carbohydrate and protein yields per feddan. The data indicated further that spraying mung bean plants with amino up to 1 L/fed. resulted in significant increases in growth parameters studied, seed yield and its related characters as compared to the untreated ones. Similar tendency could be noticed regarding the percentages of total carbohydrate and crude protein in the produced seeds, and consequently increased each of carbohydrate and protein yield per feddan. The results suggested that irrigation every 15 days and application of amino with 1 L/fed. could be recommended for maximum yield of mung bean plants under similar conditions. | ||||
