Respuesta de la caña de azúcar (Saccharum officinarum) al abonado orgánico en el norte de Belice

Abstract

Among the most productive activities in northern Belize is sugar cane; as a result, it is a livelihood and income base for many Belizeans who depend on it. However, the low productivity has been an important factor since it has limited the production yield due to high costs of inputs such as synthetic chemical fertilizers, pesticides, among others. Also, due to its intensive application, it has caused a problem in sustainability between the soil, crops and the environment. The objective of this study was to evaluate the response of sugarcane to organic fertilization in northern Belize. The work consisted of a completely randomized experimental design of 10 treatments, made up of the control (without fertilization), synthetic chemical fertilization, bokashi, bovine biol, and their combinations. The variables evaluated were: Diameter, longitude, and stem weight, maturity index, number of dry leaves, weight of dry leaves, green tops, plant weight and plant longitude. The treatment that obtained the best result was treatment ten (T10, 3 t edaphic bokashi + 2 % foliar biol). It also obtained the highest yield of tons per hectare (t ha-1) with 330; likewise, higher maturity index with 89.9 %.
