Abstract

The use of organic fertilizer in the form of manure at as dose of 5000-10000 kg.ha-1 has been practiced by corn farmers, while the Solid Organic Fertilizer (SOF) in a small dose isn’t quite is known among of corn farmer. This study aims to determine the effect of POPC combined with N P K to the results of corn (Zea mays L.). The research was carried out in Typic Eutrudepts land from in October 2013 to January 2014 use a RBD, consisting of SOF was combined nine treatment with N P K and one treatment as a control. The results of this research indicated that SOF with N P K doses improved the growth and yield of corn. Increasing the dose recommended dosage 1-2 POPC (500-1000 kg.ha-1) combined with one dose of a standard N P K can increase yields significantly, the highest result was achieved by treatment with 1 dose of 2 POPC standard N P K.Keywords: corn, solid organic fertilizer, Typic Eutropepts

Abstract

Balanced fertilization is one solution to support sustainable agriculture.This experiment was conducted to determine the study of potassium caused by balanced fertilization. The experimental method used a Randomized Block Design (RBD) single factor with ten treatments and three replications, so the total is 30 experimental plots. The ten treatments consisted of : without fertilizer (0), ½, 1, 1,5 and 2 doses of organic fertilizer + without fertilizer (0), ¼, ½, ¾ and 1 doses of anorganic fertilizer. The results of this experiments showed that there were significant effects on potencial K, exchangeable K, K uptake and yield of pakchoy from combination of organic fertilizer with anorganic fertilizer. The treatment 1½ dose of organic fertilizer + 1 dose of anorganic fertilizer produce the highest yield of pakchoy with 5.13 kg plot-1 (increase 100 % than control).Keywords: Azolla pinnata compost, litter, peat, solid biofertilizer
