Abstract

The study was conducted on LY2099 rice variety on the basis of specialized fertilizer for rice of Tien Nong Agricultural Industry Joint Stock Company and as control tretment (500kg/ha of NPKSiO2 6.8.4.3 and 500kg/ha of NPKSiO2 12.3.10.2). The other experimental treatments used specialized fertilizer for rice and combined with spraying foliar fertilizer in each treatment, including: Dau trau 502, Pisomix super-05, TrS.01, YOGEN No 2, Polyfeed 15-15-30. The reseach result showed that LY2099 rice’s growth, yield and economical efficiency in the experimental treatments were better than these in the control treatment. Specially, the treatment that supplemented used Dau trau 502 achieved the best growth and development. It also had remarkable yield and economic value comparing to others (yield 9.4 tons/ha, net profit reached 28.52 VND/ha and higher than these of control treatment 1.8tons/ha and 10.22 millions VND/ha, respectively.
Keywords: Foliar fertilizer, LY2099 rice variety, growth, development, yield.
