Response of foliar-applied nutrient solution with and without soil-applied fertilizers on growth and yield of mung bean

Hoagland's nutrient solution of 0, 25, 50, or 75% strength with or without soil-applied nitrogen, phosphorus, and potassium (NPK) fertilizers were sprayed at 7, 14, and 21 days after emergence on two cultivars (AZRI-2006 and NIAB-2011) of mung bean (Vigna radiata (L.) Wilczek). Hoagland's nutrient solution of 75% strength with soil-applied NPK fertilizers markedly increased the growth and yield of mung bean cultivars if applied at 21 days after crop emergence. However, 75% strength Hoagland's nutrient solution without soil-applied NPK fertilizers was comparable to 0, 25, and 50% strengths without NPK fertilizers. Foliar application of 75% strength of Hoagland's nutrient solution with soil-applied NPK fertilizers might enhance the yield of mung bean in low fertile areas. Performance of NIAB-2011 was superior to the other cultivar. It is concluded that Hoagland's nutrient solution of 75% strength can be sprayed at 21 days after emergence to get better yield of mung bean.
