Spatial Analysis and Upland Rice Production System in Relation to Household Food Security of Huay Loi Community, Nan Province

Abstract

Huay Loi village, Phu Fah sub district, Bo Kluea district, Nan province is sustainable community in which upland rice was community’s staple food. Nowadays some farmers grow maize crop on upland rice planting area. This situation could effect food security of Huay Loi community. This study aims to estimate upland rice growing area as well as comparison of local upland rice potential yield growing on a sloping land and analysis of food security particulaly in rice of Huay Loi village. The study divided into two parts i.e. analysis of upland rice growing area using remote sensing technique and comparison of upland rice varieties in terms of yield. Design of this experiment was randomized complete block design with 3 replications. Area analysis revealed that upland rice growing areas located on 500–820 meter above MSL sloping land (20.1–45 %). All areas situated on class 1A watershed. It was found that there was no significant difference in grain yield of 5 upland rice varieties in which average yield was 241.61 kg/rai. Analysis of food security at household level show that Huay Loi village is self sufficient in terms of rice for consumption in which the average surplus of milled rice is 168.6 kg/household.
