Giralt, E. and Tzenova, L. Optimal and altered irrigation regime in the bean crop, Phaseolus vulgaris

Agricultural Information and Documentation Centre, INRA, Havana, 1975

In experimental conditions, the optimal and altered irrigation regime of bean crop in a Ferrallitic red soil in the province of Havana was study. It was found that:
The most critical phases of the water needs of beans, appears from planting to germination and during flowering-fruiting. The lack of moisture needed for germination causes lamentable affectation in the cultivation, lack of water during the flowering-fruiting significantly affects the yield, the suspension of two irrigation in this critical stage, decrease the yield of 30 to 35%. The crop does not suffer significantly affected by suspension of 1 to 2 irrigations from germination to 10 days before flowering, or in the maturation of the pods, so that with proper irrigation water management can reduce total water requirements used.
