Cotton crops were one of the most important during the 50 and 80 decades in Northern Sinaloa, Mexico from the economical point of view. However, external factors such as monoculture and sanitary issues caused its disappearance. Due to the need of diversifying the actual pattern of crops grown in the zone, a great possibility of re-growing cotton crop exists. Actually, there is lack of updated information about irrigation and agronomic management practices of the crop. In order to contribute to a new crop planning, an integral programming model was used to estimate planting dates and windows as well as irrigation planning at different operation levels. Field experiments were conducted at different locations of northern Sinaloa during the growing season 2011-2012 in Ahome and Guasave counties. Each plot had a dimension of 2 hectares and five varieties grown with the purpose of calibrating ...

El presente trabajo de investigación se realizó con el objetivo de determinar la influencia del compost de residuos sólidos orgánicos domiciliarios en el rendimiento del Zea mays “maíz” mediante el diseño de bloques completamente al azar (DBCA) con tres tratamientos y tres repeticiones, con una incorporación de 225, 300 y 375 g. de compost por planta y un testigo (T0), además, se realizó un análisis del fertilizante (compost) obteniendo como resultado, materia orgánica 21,93%, pH 7,47 y N-P-K de 1,70% – 0,15% - 1,11% respectivamente, el procesamiento de datos de las variables se determinó mediante el análisis de varianza y comparaciones múltiples de Tukey al 95% de confiabilidad, deduciendo que existe diferencia significativa entre los tratamientos, y que los óptimos son el T1, T2 y T3, lo cual significa que el compost influye significativamente en estas variables, e...
