Abstract

Foliar fertilization is a effective application method used in these uplands as it provides good nutrition and increases crop yields. To determine the effect of foliar fertilization with monopotassium phosphate (MKP) on growth and yield of sweet potato, we analyzed plant growth, microbial communities by fatty acid methyl ester and chemical properties in soils from MKP 0 (control), 1, 2, 3, 4, and 5% treatments. Soil pH significantly increased by increasing concentration of foliar fertilization with MKP. Compared with control, the soils of MKP 3% and 4% treatments had a significantly higher community of actinomycetes while the applications of KMP 4% and 5% was significantly decreased soil fungi communities. In addition, the MKP 4% had a significantly lower ratio of cy17:0 to 16:1w7c compared with other treatments, indicating that microbial stress decreased. The highest increase in productivity of sweet potato is reached with foliar fertilization of MKP 3% treatment and optimum concentration of MKP based on regression yield curve was 2.6%. These results indicate that foliar fertilization with MKP was more effect on the productivity of sweet potato.
