Abstract

ABSTRACT Potted trial for understanding Maize (Zea mays, L.) growth responses on the given dosage of 100 kg N/ha of NPK and Urea, 100 kg P/ha of SP-36, and 100 kg K/ha KCl fertilizers growing on Latosol Kalasey was conducted in six replicates until the plants reaching 8 weeks old at the backyard of Soil Department building. Plant height and number of mature leaves increased significantly with age of Maize plants, but the plant responses on given fertilizers did not significantly different.  Fresh weight dan oven-dry weight of Maize stalk did also show similar trend due to given fertilizers; however, application of singular fertilizers, such as: Urea, SP-36 and KCl gave relatively higher results in contrast to the compound NPK fertilizer.  Urea tend to increase succulence of Maize plants. Keywords: maize, growth response, NPK, Urea, SP-36, KCl, fertilizers

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

Tailing is a type of waste produced by mining activities and is characterized by very low physical, chemical, and biological fertility, requiring efforts to amend its quality. The addition of organic materials as a soil ameliorant is one such effort of amendment to enhance success in rehabilitating these degraded areas. The aim of this study is to measure the effects of ameliorant on the growth and yield of sweet corn, determine dosage that will give the best growth and yield, and find out if residual mercury exists in the resultant sweet corn crop. This study used a randomized block design with 6 treatments: A= 40 tons/ha of organic fertilizer; B2= 50 tons/ha of organic fertilizer, C = 60 tons/ha of organic fertilizer, D = 40 tons/ha of organic+ fertilizer, E = 50 tons/ha of organic+ fertilizer, F = 60 ton/ha of organic+ fertilizer. The organic fertilizer used was a mix of 50% water hyacinth + 50% chicken manure, while organic+ fertilizer was a mix of 20% water hyacinth + 20% cow manure + 20% chicken manure + 20% traditional market waste + 20% rice straw. Every treatment was replicated four times, resulting in 24 experimental pots. Variables observed were: 1) cob length, 2) cob diameter, 3) cob weight. Data was analyzed using ANOVA and Tukey’s HSD at a test level of 5%. Results show that organic+ fertilizer increases the yield of sweet corn. A dosage of 60 tons/ha gave the best cobs with a weight of 199,89 grams per cob.

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.
