Effeet of irrigation frequency, nitrogen and phosphorus fertilization in beans (Phaseolus vulgaris L.)

Iván Gallardo A.1 y Mario Paredes C.1

In two field experiments the effects of three irrigation frequencies two levels of N and three of P, were measured during two growing seasons in beans. The soil is a clay loam Medial, Thermic, Typic Dystrandept. Irrigation frequencies had effects on grain yield, weight of 100 seeds, and number of seed per podo The fertilization and the interaction with irrigation had not effects on beans yields or yield components.
