of food crops into biofuel, starch, food and animal feed In Vietnam, cassava is the third crop in terms of yeild (after rice and sugarcane), with an area of 566.5 thousand hectares in 2015, output of 10,673.7 thousand tons The yield of cassava in Vietnam is currently 18.8 tons/ha but much lower than the potential and there are many risks in cassava production Cassava is main planted crop in Phu Yen province, is the main source of income for many poor farmers and ethnic minorities in the province In recent years, the area, yield and output of cassava have been increasing steadily Dong Xuan district has a cassave factory with capacity of over 240 tons of starch/day and 05 branches of simple processing with capacity of 0.5 - 1.0 ton/day The cassava varieties in Phu Yen province are mainly KM94, KM98-5 and KM140 The cassava variety KM94 is now degraded, infected with dragon brooms due to continuous cultivation for many years Cassava KM98-5 and KM140 are short duration of cultivation and high yield, but the production has many problems The main problem of cassava production in Phu Yen is that farmers not invest in intensive cultivation, using old varieties of low yield and low production efficiency In recent years, cassava production has encountered many difficulties and risks due to climate change such as drought, pests such as Phytoplasma sp, Phenacoccus manihoti, Tetranychus sp Based on the above analysis, we conducted the study "Study on the selection of high starch yield varieties and intensive cultivation techniques in phu yen province" 2 Research objectives - Selection of good cassava varieties suitable with climate and soil conditions in Dong Xuan and Song Hinh districts of Phu Yen province - Determine the intensive cultivation techniques of cassava in Phu Yen province suitable for selected cassava varieties - Develop demonstration models of new cassava varieties and improve the cultivation techniques suitable to the conditions in Phu Yen province Scientific and practical significance 3.1 Scientific significance - The study has identified the Cassava KM419 and the intensive cultivation technique that is suitable with the local ecological conditions, contributing to the improvement of the yield of root, starch yield and dry slice yield, profit and economic efficiency for farmers in Phu Yen province - The research results are an important source of information to guide sustainable cassava cultivation techniques in Phu Yen province and other provinces with similar ecological conditions 3.2 Practical significance Research results have high feasible application, proposed promissing Cassava KM419 and suitable cultivation techniques for selected cassava varieties in Dong Xuan and Song Hinh districts, enriched with high productivity cassava varieties , good quality and replacement of KM94 planted but degraded and infected in Phu Yen New contributions of the thesis (1) Identify appropriate and effective cassava varieties for Phu Yen province: The KM419 cassava variety and the selected cassava varieties KM440, KM444, KM397 had higher yield of tubers, higher starch yield and better dry yield of cassava chips
