CROP SUSTAINABILITY EVALUATION OF CAVENDISH BANANA (MUSA ACUMINATA) PRODUCTION IN BARANGAY BATOMELONG, GENERAL SANTOS CITY USING GIS

The study aimed to generate a land sustainability map of Cavendish Banana Production map in Barangay Batlomelong, General Santos City. The sustainability evaluation was based on the following parameters: soil pH, Nitrogen, Phospherus, Potassium, Organic Matter, Soil Texture, Temperature, Annual Rainfall, Relative Humidity, Elevation, and Slope. Soil-related parameters were measured in every one-hectare grid of the Barangay on Jan to 2018 and climate-realated factors were acquired from DOST-PAGASA. The Crop Sustainability Evaluation can be interpreted through the maps generated using Geographic Information System software. Based on the different maps, mostly of the areas in the barangay are suitable for the production of banana. The areas of the barangay have sufficient amount of nutrients succh as Phophurus and Potassium which is required for the production. Though, nitrogen was low on the most areas in the barangay it can be amended by adding fertilizer to it. An Analytical an Hierachial Procees was used to determine relative of criteria and showing result weights were used to construct the sustainabilty maps/layers using Quantum GIS software. For future study, the researcher recommends conductiong the study annually since the nutrients and organic matter present in the soil may change due to different factors that can affect the quality of the soil. Also, the results can be used by the local government to give farmers the information needed by a Cavendish banana farmer.
