ABSTRACT
Cultivation Technique of Sidimpuan snakefruit (Salacca sumatrana Becc.) needs to be improved in an effort to increase the production of snakefruit which has continued to decline. Optimal production of Sidimpuan snakefruit can be achieved if the factors internally and externally that support the growth and development of plants are well available for plants. There are three essential nutrients that determine the growth and development of plants, namely nitrogen, phosphorus and potassium. The application of ammonium sulphate fertilization is one of the efforts to improve the cultivation technique of Sidimpuan snakefruit so that the production increase is achieved. This study aims to determine the ratio of Nitrogen, Phosphorus and Potassium content leaves of Sidimpuan snakefruit before and after fertilization. This research has been carried out in snakefruit planting in Palopat Maria Village, Padangsidimpuan Hutaimbaru Subdistrict, Padangsidimpuan City with altitude of ± 450 m above sea level. This research starts from November 2017 to June 2018. The research method used is experimental and survey methods with purposive sampling technique in determining sample plants. Number of plants sample 30 plants. Data processing was carried out using the Independent Test sample t-test. Based on the results of this study, it was found that the comparison of nitrogen and phosforus content of leaves before and after first fertilization was not significantly different, however potassium content is significantly different , while the content of nitrogen, phosphorus and potassium content before and after the second fertilization was significantly different.
