ASSESSMENT OF AGRICULTURAL FEATURES SOME GENERAL SOURCES OF VARIOUS FRAGRANCES IN 2017 IN THAI NGUYEN PROVINCE

Abstract

The experiment was conducted with 10 samples of cassava varieties from 2 groups (cassava and high-yield cassava). The samples collected in the northern mountainous provinces of Vietnam had good growth, fresh tuber yield ranged from 13.8 to 39.6 tons/ha and dry tuber yield from 5.5 to 15, 8 tons/ha. In the experiment, SCSLUN and CSTRANG varieties had high fresh and dry tuber yield (fresh tuber yields: 38.0 - 39.6 tons/ha; dry tuber yield: 14.7 - 15.8 tons/ha). The starch yield of cassava yield varied from 4.0 to 10.9 tons/ha, in which SCSLUN and CSTRANG varieties varieties had high starch yield ranged from 10.1 - 10.9 tons/ha.
