WATER FOOTPRINT ANALYSIS USING BY CROPWAT 8.0 OF MARIAN PLUM : CASE STUDY IN PAKA SUBDISTRICT, BANNA DISTRICT, NAKORNNAYOK PROVINCE

Abstract

The purpose of this research was to analyze the water footprint using the CROPWAT 8.0 program of Marian Plum in Paka Subdistrict, Banna District, Nakornnayok Province. The data collected from the questionnaire were collected from 57 farmers. Secondary data includes climate data, water use of plants, soil series data. The result of this study showed all of farmers will grow Marian Plum (Bouea macrophylla) cv. Toon Klaow. The water used for cultivation comes from rain water, natural canal and pond. Duration of irrigation 3 days / time. Fertilizer and pesticide use in the maintenance phase. The water footprint analysis of Marian Plum plantation showed that the WF total was 627.5 m³/tonne, consisting of 590.5 m³/tonne of green water footprint (WF green) and gray water footprint (WF gray) 37.0 m³/tonne. Ratio of water footprint of WFgreen: WFblue: WFgray rating is 94.1: 0: 5.9. Water Scarcity Footprint of Marian Plum in Nakornnayok Province at 1.13 m³. The study found that water shortage was not suitable for growing in the area. The use of less chemicals, which is consistent with sustainable production and consumption practices.
