Abstract f Objective ]The effects of differenl compound fertilizers on cassava biology properties. yield and starch
content were studied to provide references for producing compound fertilizer suitahle for cassava ield. [ Method Random
ras used for field experiment. Plani height, slem diame
root yield and starch content were tested
in 7 treatments including 6 kinds of compound fertilizers and the control(no fertilizer application.[Result Compared to
ne control, Flezhongwang ruut expausion corupwund Fertilizer markedly increased stem diameter at the later growth stage
P<0.0, the same below) while other fertilizers had no abvious effects on plant ht
or stem diameter. kresh root
was increased after fertilizer application with Luixianji and Guil cassava fertilizer being the best.The starch eontent was
decreased after 6 kinds of compound fertilizer application, and starch content of Hezhongwan root expansion compound
fertilizer was mosl significantly decreased. The starch yield of 6 kinds of fertilizer application was increased except
Ing root expansion compound fertilizer. The income of cassava planting was increased after fertilizer applicalion
except Nanfeng cassava fertilizer. Guilu cassava fertilizer followed by Lix anji roughl mosl income. Generally speaking
the elects of Guili cassava ertilizer were the est with fresh root increment of 6310 k ha(25.2%), starch yield increment
of 16.7% and income increment of 2735 yuan/ha. The second best was Luxianii cassava fertilizer with fresh mot increment
of 5533 k/ha(22.1%), stareh yield increment of 13.6, and income increment of 1873 uana. [Conclusion]All m-
pound fertilizers are beneficial for cassava grumwing and yicld inerease. Guili and Lixianj were the top two best
