THE IMPORTANCE OF IRRIGATION IN SOYBEAN YIELD IN THE VALLE DEL FUERTE

Abstract

The northern region of Sinaloa State, Mexico, has a high potential for irrigated agriculture. How­ever, when soybean (Glycine max L. Merr) is cultiva­ted in this area, the first irrigation after planting is carried out too early, causing low growth and yield. This paper reports information obtained dur­ing four years, regarding water use and management. The results indicate that it is possible to save to up 5O% of the water used in irrigating soybean with no effect on seed yield.
