Research results in crop 2010 and 2011 showed that seasonal and density affect the growing time, resistance to pests and unfavorable conditions of glutinuos rice yellow flowers variety and so affect the yield components and yield. Seasonal implants soon, glutinuos rice yellow flowers variety have the longest period of growth, plant nutrient growth long time, accumulated more dry matter, highly effective branching ratio, number of firm rice grain more, mass of thousands seeds - high, rate of pest and disease is low
high density have total flowers effective on the unit area high. In soil, climate conditions in Thanh Hoa, based fertilizers (10 tons of muck + 60 kg N + 45 kg P2O5 + 60 kg K2O)/ha, culture crop glutinuos variety yellow flowers is best from 05-15/6, culture density of 40 clusters/m2 high yield (3860-3900 kg/ha) and best quality.
