Evaluation of an organic amendment on agronomic variables and yield of Sorghum bicolor in La Frailesca, Chiapas, Mexico

| Sumario: | In the Frailesca region of Chiapas, Mexico, conventional sorghum (Sorghum bicolor) production has decreased soil fertility, primarily by reducing its organic matter. This makes it necessary to look for alternatives to increase its yield, since it is an important cereal for animal feed. This study aimed to evaluate the agronomic and productive response of sorghum to the application of three doses of compost. It was conducted during the spring-summer 2018 agricultural cycle, under rainfed conditions in the municipality of Villaflores, Chiapas, Mexico. The treatments were a control and three doses of compost (10, 20 and, 30 t/ha-1), incorporated into the soil before planting. Four experimental plots per treatment were established using a completely randomized design. The response variables were agronomic and productive, and they were evaluated using analysis of variance and a mean comparison test. Both the agronomic parameters (plant height, stem thickness and biomass fresh weight) and the productive parameters (grain weight and yield, panicle length and weight) were statistically superior in the 20 and 30 t/ha-1 compost treatments compared to the 10 t/ha-1 treatment and the control. |
