Abstract
The research contents included: basic experiment, production experi-ment, demonstration trial production of two new rice varieties selected and experimental development of rice cultivation techniques for Tuy Hoa plains. This report presents part two: Results of production exper-iment, demonstration trial production of two new rice varieties selected in Phu Yen province. The study was conducted in 4 seasons (Winter-Spring 2015 - 2016, Summer-Autumn 2016, Winter-Spring 2016 - 2017 and Summer-Autumn 2017) at intensive farming soil area in Hoa My village of Phu Hoa district, and Hoa Thang village of Tay Hoa dis-trict, Phu Yen province with 4 advanced rice varieties (GSR65, GSR90, GSR38 and Nam Uu 1245) and ML 48 used as control. Experimental method in accordance with National Technical Regulation QCVN 01-55: 2011/BNNPTNT Experiment on value of cultivation and use value of rice varieties. Results of the four production experiments in two se-lected crops and the four demonstration trial production of two new rice varieties selected, two the GSR65, GSR90 rice varieties had high yield, good quality, good agronomic traits, short growing time (A1), low pest infestation, suitabe for export and success construction demonstration model on farmer field in Phu Yen.The GSR65 and GSR90 varieties gave the average yield of 79.8 and 81.7 quintals/ha, exceeding 11.92% and 14.58% respectively compared to control ML48 reaching 71.3 quintals/ha, and the profit was 30.5-36.7% higher than that of ML48 at 15.50 million VND/ha. The GSR65 and GSR90 rice cultivation techniques have been developed.
