The objective of this study was to determine the responses of ‘Bush Blue Lake-47’ snap bean plants [Phaseolus vulgaris (L.) var. humilis] to urea, (NH4)2SO4, NH4NO3, and Ca(NO3)2 sources of N fertilizers at rates of 0, 4, 8, or 12 g of N/m2 and to KCl and K2SO4 fertilizers at 5 g K/m2. Dry weight of the plants was determined at the seedling, bloom, and harvest stages. Blades of recently fully expanded leaves at the bloom stage were analyzed for total N, NO3-N, Cl, S, B, P, K, Na, Ca, Mg, Zn, Mn, Fe, and Cu. Snap bean plants grown with (NH4)2SO4 had the highest dry weight per plant and the highest yield of pods, followed by plants grown with NH4NO3. Plants grown with Ca(NO3)2 or urea had the lowest dry weight per plant and the lowest yield of pods, especially at the highest rate of N fertilizers.
