Abstract

The purpose of this experiment was to determine the best nitrogen and kalium fertilizer dosage to increase yields and quality of sweet potato. The experiment was conducted at Bandongan Kulon, Ngablak, Magelang, Central Java Province during the period of May up to October 2005, on latosol soil and 1,300 m height. A factorial experiment of 3×3 factors was employed, where the treatments were arranged in Randomized Block Design with three replicates. The first factor was nitrogen fertilizer dosage that consisted of three levels, i.e.: 46 kg N/ha equal with 100 kg Urea/ha, 92 kg N/ha equal with 200 kg Urea/ha and 138 kg N/ha equal with 300 kg Urea/ha. The second factor was kalium fertilizer dosage that consisted of three levels, i.e.: 60 kg N/ha equal with 100 kg KCl/ha, 120 kg N/ha equal with 200 kg KCl/ha and 180 kg N/ha equal with 300 kg KCl/ha. The result of the research showed that no interaction between nitrogen and kalium fertilizer dosage on the number of tuber per plant, weight of tuber per plant and weight of tuber per sample, but they increased yields quality significantly. Nitrogen 92 kg/ha and Kalium 180 kg/ha produced the highest sucrose contents, Nitrogen fertilizer 138 kg/ha and Kalium fertilizer 60 kg/ha produced the highest tuber starch, Nitrogen fertilizer 46 kg/ha and Kalium fertilizer 120 kg/ha produced the highest β–karoten.Keywords: Nitrogen, kalium, fertilizer, sweet potato

Abstract

The community service program, packaged in the Kedaireka Matching Fund (MF), aims to help farmers to be able to commercialize their agricultural products. There are two outcomes of this Kedaireka-MF community service: an organic fertilizer factory and a frozen vegetable factory. Several methods are carried out to support the creation of commercialization. The Kedaireka-MF community service program starts with commercialization socialization, assistance in making organic fertilizers, assistance in making frozen vegetable factories, and assistance in digital marketing. Digital marketing platforms that can be made are websites, Instagram and YouTube. Kedaireka-MF has also registered its products through the Shopee e-commerce platform. To improve the quality of commercialization, the Kedaireka-MF community service program has started a new business with a legal entity, CV Reka Tani Mandiri. This MSME company was established as a forum for farmers to commercialize agricultural products in a professional manner.
