Effect of Season of the Year on Yields of Several Varieties of Dry Beans Growing in Two Ecological Regions of Puerto Rico

Abstract

Beans (Phaseolus vulgaris) yielded most at Orocovis, in the humid mountain region of Puerto Rico when they were planted in November and May, and least when planted in March and September. The varieties Black Turtle and Bonita 2, 3 and 8 produced the highest average yields. In Gurabo, in the humid Caguas valley beans yielded highest when they were planted in November, January and March. Yields started to drop off in the May plantings and were very low in the July and September plantings. The varieties Violets and Naranjito produced the highest average yields.
