ABSTRACT

 

The effect of fermented liquid organic fertilizer and potassium for nutrient uptake and yield of rice at tropical upland has been conducted in screen house at Padang, West Sumatera from Juni to November 2013. The goal of research was to get the right formula of natural fermented organic fertilizer in various compositions to substitute the use of potassium fertilizer at tropical upland rice. Experiments conducted in factorials the form of treatment with 2 factors, at first factor consisted of 5 types of organic fertilizer compositions, namely; P1. (20% C.odorata + 70% coconut fiber + 10% activators), P2 (40% C.odorata + 50% coconut fiber + 10% activators) ; P3. (60% C.odorata + 30% coconut fiber + 10 % activators); P4. (80% C.odorata + 10% coconut fiber + 10% activators), P5. (activators), and second factor consists of three levels, namely K2O ; K0 . 0 kg ha-1 ; K1 . 25 kg ha-1 K2. 50 kg ha-1 at a dose of liquid organic fertilizer given 1 : 5 (liquid organic fertilizer and water), given every 2 weeks, which began at planting. Replication of treatments was performed 3 times, so it found as many as 5 x 3 x 3 = 45 experiment pots. The data were analyzed using analysis of variance (F test) and could be continued by HSD test at 5% significance level. Parameters were observed during the treatment, among others. Analysis of nutrient content and composition of the liquid organic fertilizer includes macro nutrients (N, P, K, C-organic, pH) and micro (Fe, Mn, Zn, Cu, B and Co). Analysis of plant cover; nutrient uptake, N, P and potassium, weight of dry milled grain. The results showed that P2 without applying the potassium fertilizer application improved nutrient uptake of N, P and potassium and grain yield up to 29% at tropical upland.
