Abstract In a field experiment, various strengths of Hoagland’s nutrient solutions were sprayed to mitigate the deleterious effects of nutrient stresses at different growth stages on mash bean cultivars. Hoagland’s nutrient solution strengths of 0, 25, 50, and 75% were applied at 7, 14, and 21 days after emergence on mash bean cultivars namely Mash-2 and Mash-88. Hoagland’s nutrient solution of 75% strength markedly increased the growth and yield of mash bean cultivars if applied at 21 days after crop emergence. The Mash-88 showed superiority in terms of growth and yield traits as compared to Mash-2. The results suggested that growth and yield was not enhanced effectively by a low strength of Hoagland’s nutrient solution applied at initial growth stages. It is concluded that foliar-applied Hoagland’s nutrient solution of 75% strength can be used as an efficient tool when applied at appropriate growth stage (21 days after emergence) to get optimal yield.
