Abstract
The experiment was conducted to observe the effect of nitrogen,phosphorus,potassium and boron application amount on the growth and yield of sunflower at Liaoning Academy of Agricultural Sciences in 2009.The results indicated that increasing N,P,K and B fertilizer would improve the growth and yield significantly of sunflower.The highest leaf area index of F3(3.86) and F6(4.12) were higher than that of F7(CK 3.70),respectively,the leaf area duration(LAD) of F3 and F6 at growing season were 1 393 750 and 1 449 750 m2·d,higher than that of F7(1 258 250 m2· d).The time of highest biological yield accumulation rates of F3 and F6 were 67.1 d and 64.6 d after sowing,later than that of F7(55.4 d),the highest dry matter accumulation rates of F3 and F6 were significant higher than others,then the dry matter and yield were the highest.
