Abstract
The aim of this study was to investigate the optimal growing season, planting density and fertilizer levels on the development of "Huyet Rong" herbal rice variety in Quang Tri Province. Particularly, four formulas of each growing seasons, planting densities and fertilizer levels were designed to evalute the growth, development, productivity, and major insects/diseases resistance of the "Huyet Rong" herbal rice variety. As a result, the growing season from middle - last October (from 15th to 25th, October) has been demonstrated to be the optimum stage for rice production as the productivity reached the highest value by 3.5 - 3.7 tons/ha. Next, we found that the planting density of 30 - 35 hills/m2 and the formula of (1 ton of cattle manure + 60 kg P2O5 + 50 kg K2O with an additional of 50 - 70 kg N)/ha exhibited the highest yield. The rice variety was also slightly susceptible to major pests and diseases. Our analysis indicated that the grain contains high anthocyanin content (534.8 mg per 100 g), protein (8.90%), vitamin, Fe and Ca. Taken together, our study could provide critical data for further establishment of the cultivation of Huyet Rong herbal rice variety in Quang Tri province.
