KANDUNGAN HARA FOSFOR DAN KALIUM DI SEKITAR PERAKARAN TANAMAN UBI KAYU (Manihot Esculenta Cranz)

Abstract

ABSTRACT

Cassava is a food crop that is widely grown in the village of Salurang, Tabukan Selatan Tengah
District. To develop this plant so that it produces better, it is necessary to conduct research on
the availability of nutrients around the roots. P and K elements are elements needed by cassava
plants, therefore it is necessary to research the availability of nutrients around the roots. This
study aims to determine the nutrient content of phosphorus and soil potassium around the roots
of cassava. The benefit of this research is to determine the right fertilizer in to increase the
production of cassava plants. The research method used a survey method with purposive
sampling on cassava plants which have tubers and have not. Sample analysis using the dry soil
test (PUTK) version 1.0. Bogor Soil Research Institute The results of the analysis showed that
the phosphorus nutrient content around the roots of the tuberous cassava plants ranged from low
to moderate, while potassium was low to high. Cassava plants that have not been rooted show
that the phosphorus content is moderate, while potassium ranges from moderate to high.
