Abstract

Organic farming systems utilize organic fertilizer as the main source of nutrients for the crops. The application of organic fertilizer from animal sources, such as manure, can increase soil fertility and crop yield. This research aims to: 1) Study the effects of organic fertilizer dosage and time of application towards the fresh weight of mustard greens, and 2) determine the best application time for the maximum fresh weight of mustard greens. Factorial research with two factors was designed using a randomized block design. The first factor was dosage of organic fertilizer (A): A1 = 15 ton/ha, A2 = 20 ton/ha, A3 = 25 ton/ha, and A4 = 30 ton/ha. The second factor was the time of application (B): B1 = 10 days before planting the seeds, B2 = 15 days before planting the seeds, B3 = 20 days before planting the seeds. Every experimental unit was replicated three times, yielding 36 experimental pots. The variable observed was the fresh weight of mustard greens. Data were analyzed using ANOVA, followed by Tukey's honest significance difference test (alpha = 0.05) if significant differences were found. Results show that the interaction between dosage and time of application had significant effects on the mustard greens' leaf length, plant height, leaf count, leaf width, and fresh weight. Treatment A3B1 (25 ton/ha of organic fertilizer, applied 10 days before planting seeds) gave the heaviest weight (24,07 gram). The longer the application time, the better the effects on the plants. The application of organic fertilizer requires 10 days of incubation before the mustard greens are moved.

Abstract

Chili is a strategic commodity with important economic value in Indonesia. The Ministry of Agriculture included chili in a special program as of 2015 to increase production. Chili as a commodity has a high impact on Indonesia’s economy, party because fluctuations in its price can influence inflation. Data from the Central Statistics Agency indicate that chili supplies decrease during the rainy season while demand increases in the months of Ramadhan, Christmas, and New Year, and in these times chili prices increase and cause inflation. To support national demand, there needs to be an increase in chili productivity. Chili plots sometimes cannot be planted year-round due to the high use of artificial chemical fertilizer with excessive dosage, thus decreasing the quality of land and quality and volume of chili crop yield. For that reason, there needs to be a study that identifies cultivation techniques for chili in the regency of Southeast Minahasa. Study results show that cultivation methods in Molompar village, Southeast Minahasa, still depends on farmers’ experiences. Field instructors have not been optimally guiding the local farmers.
