Abstract

Molucca, in general and especially Ambon has ground nut fields with low productivity compared to national yield of ground nut. Brunizem has low levels of K and P nutrients. These conditions were interesting to be investigated. The research took place in a plastic house for two months in Halong village, sub district Baguala. The research was done in a Completely Randomized Design with 2 Factors. The first factor was three levels of K fertilizer, ie K0 (no K fertilizer application), K1 ( 0.5 g KCl/pot) and K2 ( 1.0 g KCl/pot). The second factor was three levels of P fertilizers, ie P0 (no P fertilizer application), P1 (0.6 g SP-36/pot), and P2 (1.2 g SP-36/pot). The aim of the research was to investigate the availability and sorption of potassium, growth and dryweight-of ground nut (Arachis hypogaea L.) seed due to the application of KCl and SP-36 fertilizers on Brunizem. The results of this research showed a high significant effect of potassium fertilizer treatment on soil-pH, availibility and sorption of K, plant height, stem diameter, and dryseed weight of ground nut. Treatment g P fertilizer has a significant effect on soil pH, available K, plant height, and dry weight of seed. The interaction of K and P fertilizers had no significant effect on K availability and sorption of K. K availability of 0.26 me/100 g and 4.95% of plant-K was attained at the treatment of 1.0 g KCl/pot. The high dry yield of ground nut (17.35 g/pot) was achieved at dose of 1.0 g KCl/pot, meanwhile dose of 1.2 g SP-36/pot gave the highest seed-dry yield of ground nut
