Growth, Yield and Seed Quality Trails of Black Glutinous Rice Cultivars in Upland Area of Khlong Hoi Khong District, Songkhla Province

Abstract

This study aimed to evaluate the growth, yield and seed quality of two black glutinous rice cultivars (Pluak Dum and Pluak Khao) for planting in the upland areas of Khlong Hoi Khong District, Songkhla Province. Randomized Complete Block Design (RCBD) was laid out with 2 replications. The experimented plot was sized 20x20 m. The results showed that both rice cultivars had no different growth patterns and yield potentials. Plant height, Yield, numbers of perfect seed per panicle, germination indices and standard germination (between paper) of Pluak Dum were 129.73 m, 355.56 kg/rai, 156.30 seed, 15.93 and 83.50%, respectively. While that of Pluak Khao were 133.33 m. , 360.89 kg/rai, 186.50 seed, 18.65 and 94.50%, respectively. These two rice cultivars possessed high potential for cultivation in the upland cropping environments. They should be recommended to the farmers for planting in the upland areas or practicing the intercropping systems as their cultivation may supplement incomes to the farmers. Continual cultivation of these local rice cultivars may play a role in maintaining and preserving these two indigenous black glutinous rice cultures.
