Water spinach is a heavy metal accumulator plant if grown in polluted soils. This raises the concern of water spinach safety as one of the most consumed vegetables in Asian household. Land pollution in water spinach cultivation area can be caused by industrial activities that involve heavy metals such as tannery. Industrial waste such as chrome leaches to the water system that eventually will be used as irrigation source for agriculture. Organic fertilizer is a potential solution to increase water spinach growth, yield, and absorb heavy metal contaminants. This research evaluated the effect of type and dosage of organic fertilizer on water spinach that grown in chromium-polluted soils. This research design used Randomized Block Design (RBD) with nine treatments and three replication. The treatment of combination of types and dosages of organic fertilizer. There were dried leaves, goat manure, and vermicompost with dosage of 5 t ha-1, 10 t ha-1 and 15 t ha-1. The results of this research showed that the effect of combination of organic fertilizer type and dosages at chrome polluted media gave better effect on growth, and yield of water spinach. Giving vermicompost of 15 t ha-1 gaves better effect on plant height, fresh weight of plant, and dry weight of plant, meanwhile the doses of 5 t ha-1dried leaves showed the lowest chrome content compared to other treatments, but these plants are still unsafe for consumption due to high chrome content.Keywords: water spinach, organic fertilizer, chromium, yield

Planting shallots in Buahan Village is only carried out once a year, namely in July. The continuous use of synthetic fertilizers at high doses without being balanced with natural fertilizers has degraded the land so that soil fertility has decreased. The negative impact caused is a decrease in the yield of shallots. Quality organic fertilizers can overcome this problem. Organic vermicompost and biosllury fertilizers are quality organic fertilizers that can replace synthetic fertilizers to increase the growth and yield of shallots. The research objective was to determine the growth and yield of shallots by giving the type and dose of organic fertilizers outside the growing season. The research was conducted from March to July 2019 in Buahan Village, Kintamani District, Bangli Regency. The study used a simple randomized block design with one factor with 6 treatments, namely B0 (Without Organic Fertilizer), B1 (2000 kg / ha vermicompost); B2 (1000 L / ha biosllury) B3 (1000kg / ha vermicompost + 500 L / ha biosllury); B4 (4000 kg / ha vermicompost); B5 (2000 L / ha biosllry); B6 (2000kg / ha vermicompost + 1000 L / ha biosllury); B7 (4000 kg / ha vermicompost + 2000L biosllry) and B8 (5000 kg / ha vermicompost + 3000L / ha biosllury). The parameters observed were plant height, number of tillers, tuber wet weight per clump, harvest dry weight of tubers per clump and number of cloves per clump, soil pH, N-total (%), C-organic and total population of soil microorganisms. The results showed that the type and dose of organic fertilizer had a significant effect on all the meters observed. Treatment of 5000 kg / ha vermicompost + 3000L / ha biosllury gave the highest yield, namely 56.8 g per clump, 60% higher than the control 35.5 g per clump.

Onion (Allium ascolanicum L.) is not only popular as cooking spices in Indonesia but also throughout the world. Onion that has high economic value, has its own attraction to be cultivated by farmers. However, farmers often face some problems in onion farming. Problems were faced by farmers related to social economic conditions both internal, external and natural conditions. Fertilizer application for onion can use inorganic and organic fertilizer materials. The use of inorganic fertilizers without the addition of organic fertilizers over a long period of time, suspected to cause a decrease in soil physical and chemical capabilities, with the application of solid and liquid organic fertilizer is predicted to be more effective because the elements are more than one element. The use of fertilizers and organic matter through soil is often inefficient because of the fixation by soil particles. Liquid fertilizers administered overcome gapnutrients during growth. Herbafarm liquid organic fertilizer is a type of liquid fertilizer released by PT. Sidomuncul herbafarm which contains bio protectant, processed from by products of medicinal products made from raw medicinal plants and spices. Herbafarm contains macro and micro nutrients and also organic compounds that are essential for the growth and development of plants. This research was conducted in Sidera village, Biromaru sub-district, Sigi regency, Central Sulawesi Province. This study used a Randomized Block Design consisting of 5 treatment levels: P0 = control, P1 = 1 ml/liter of water, P2 = 2 ml/Liter of water, P3 = 3 ml/liter of water, and P4 = 4 ml/liter of water. All treatments were repeated 4 (four) times, so that there were 5 treatments each time 4 replicates = 20 experimental units.
