Abstract

A mixture of fishpond sediment and goat manure can be used to increase the growth and yield of sweet corn. This research aimed to determine the effect of pellet from the combination of fishpond sediment and goat manure with a ratio 1:1 on nutrient (N, P, and K) and yield on sweet corn. The land used was Ultisol Dramaga which was located in Cikabayan Experimental Farm, Bogor Agricultural University. The study was conducted in a greenhouse with a Completely Randomized Design (CRD) of one factor with eleven treatments: without treatment (control); standard fertilization (Urea 0.43 ton ha-1, SP-36 0.41 ton ha-1, and KCl 0.25 ton ha-1); three doses of pellet (20 ton ha-1, 30 ton ha-1, and 40 ton ha-1); three doses of fishpond sediments (10 ton ha-1, 15 ton ha-1, and 20 ton ha-1); three doses of goat manure (10 ton ha-1, 15 ton ha-1, and 20 ton ha-1). The result showed that giving 40 ton ha-1 pellet had a significant effect on the increasing pH, ammonium, and the availability of K in Ultisol and nutrient content of P, K, and the weight of dry-grain sweet corn.

Abstract

Rice is a strategic commodity, so efforts to increase its production continue to be carried out, one of which is by increasing fertilization efficiency. The government has set policies in the field of fertilization, one of which is to provide fertilizer recommendations for rice plants based on specific location. The objective of this research was to evaluate the fertilization policy written in Permentan RI No. 40/Permentan/OT.140/4/2007. The methods were analyzing the variance values for each type of fertilizer recommended and validating N, P, and K levels in selected locations. The results of the study showed that the fertilization recommendations set by the government still need to be improved because there were still many discrepancies with conditions in the field. The adjustment of recommendation dose with the addition of organic materials were relevant and can be implemented, but it is still required further socialization to farmers. Reformulation of subsidized fertilizers, from NPK fertilizer 15-15-15 to NPK fertilizer 15-10-12 also had not been able to increase fertilization efficiency, because it actually made the dose of NPK becomes higher, but did not reduce the addition of a single fertilizer significantly. Subsidy policy also needs to be reviewed, because farmers did not fully get subsidized fertilizer so the farmers could not meet the needs of their fertilizers. Regarding the implementation of fertilization information, a soil big database must be created nationally to make specific location fertilization recommendations, and this must be easily accessed by farmers. Keywords: fertilization policy, organic material, soil big database, subsidy
