Description
Summary:Inorganic fertilizers that are applied take a certain time to be available in the soil. The application distance between types of fertilizers is needed with the aim of reducing antagonistic properties, both antagonistic properties between nutrients and between types of fertilizers so as to increase the effectiveness of fertilizer absorption. The purpose of this research study the pattern of nutrient release and the interaction of several chemical fertilizers at the oil palm nursery stage. This research was divided into 2 stages, namely the preliminary stage to determine the optimum dose of each type of fertilizer and the stage of testing the antagonism of 2 different types of fertilizers from 5 types of fertilizers, namely Urea (N), Rock Phosphate (P), MOP (K), Kieserite (K), and HGFB (B). The experimental design used a non-factorial Randomized Block Design , with 45 treatments and 4 replications. The results showed that the optimum doses of the three leaf nutrients were obtained at 40 g/seed for RP, 45 g/seed for K, and 50 g/seed for Borate. The optimum nutrients for N and K fertilizers have not been obtained, so the highest dose from the test level is used, which is 80 g/seed respectively. The results of statistical analysis show the ideal distance of application time between RP and MOP fertilizers, RP with Kieserite, RP with HGFB, MOP with Kieserite.
