Effect of foliar spray with urea and some micronutrients on mungbean [Vignal radiata [l.] wilczek] growth, yield and seed chemical composition

ABSTRACT

The objective of the experiments was to study the effect of foliar spray with some nutrients on growth, yield and seed chemical composition of Kawmy-1 variety mung bean [Vigna radiata [L.] Wilczek]. The foliar treatments were urea [1%], and four key micronutrients, Fe [0.5%] Zn [0.1%], Mn [0.2%] and CuSO4 [0.05%]. Micronutrient treatments were spray either alone or combined with urea at early pod-setting. The obtained results showed that foliar spray with either Fe and Zn alone or urea in combination with Zn or Cu gave the tallest plants. Application of urea or Zn increased the number of branches per plant, while the greatest number of leaves per plant was produced from the combined application of urea with Mn, Zn and Cu. The heaviest dry weight of mung bean plants was recorded when the plants were treated with Fe alone or combined with urea
