Hubungan Ketersediaan Hara N, P, K Tanah Terhadap Padatan Buah Salak Sidimpuan (Salacca sumatrana Becc.)

Abstract

This study aims to determine the relationship between the availability of Nitrogen (N), Phosphorus (P), and Potassium (K) soil nutrients to the dissolved solids content of sugar in Sidimpuan snake fruit (Salacca sumatrana Becc.). The study was conducted in three Sidimpuan snake fruit cultivation locations, namely South Angkola, West Angkola and East Angkola, with three soil and fruit samples at each location. Data analysis used simple linear regression (SPSS 30). Based on the results of the linear regression analysis, it can be concluded that there is a positive relationship between the availability of N, P, K soil nutrients to the sugar content of snake fruit has a positive relationship, and the correlation coefficient is 0.266 (low), the correlation coefficient of soil P to the sugar content of snake fruit is 0.459 (moderate) and the correlation coefficient of soil K to the sugar content of snake fruit is 0.131 (very low), meaning that the higher the presence of N, P, K in the soil, the sugar content in the fruit will also increase.
