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

Red onion production can be increased by fertilization. Fertilization serves to provide nutrients for plant growth. Chemical fertilizer provides a bad impact on the environment in the long term so that the application of organic fertilizer can be a recommendation. Organic fertilizers are fertilizers derived from animal matter, animal manure, human excreta, and vegetable matter (e.g. compost and crop residues). Waste mushroom logs, cow manure fertilizer, and decomposers used in this research. All of the matter in this research can be a source of nutrients for growing plants and an increase of production and yield of red onions. The objective of this research was to study the combination test between of waste mushroom logs, cow manure fertilizer, and decomposers to growth and yield of red onion. This research was arranged in a Randomized Block Design (RBD), where the main plot is cow manure fertilizer and waste mushroom log, the subplot in the form of a decomposer. The results showed that there was not interaction between cow manure fertilizer and decomposer waste on all parameters of observed growth and yield of red onion. Special decomposer real treatment of the growth of the number of leaves of plant ages 15 HST (18.98), 20 HST (20.33), 25 HST (23.47), 30 HST (25.76), and 35 HST (26.11), and plant height is 35 HST (33.21 cm).

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.

To produce optimally good quality shallots, proper cultivation techniques are required. Efforts that can be made include modifying the environment in which plants grow. Alternative efforts to increase the quantity and quality of agricultural products, especially shallots can be done by using organic fertilizers and the use of Trichoderma sp. as a plant growth promoting agent, as well as improving the quality of organic fertilizers. The purpose of this study was to determine the role of Trichoderma in increasing the ability of plants to absorb nutrients from the growing media and to determine the best type of organic fertilizer to increase the growth and yield of shallots. The research was conducted at the experimental field of the Faculty of Agriculture, UPN "Veteran" Yogyakarta, Wedomartani, Sleman, Yogyakarta Special Region, at an altitude of approximately 104 meters above sea level. The time of the research is from May to July 2021. This study was arranged in a factorial Completely Randomized Block Design with 3 replications. The first factor is the type of manure (P1: without manure, P2: cow manure and P3: goat manure). The second factor was inoculation of Trichoderma sp isolates (I0: without inoculation of Trichoderma sp. isolates. and I1: by inoculation of Trichoderma sp. isolates). Based on the results of this study, it can be concluded that the addition of cow and goat manure was able to produce more leaves and plant height than without the addition of manure, although it did not show a significant effect on the yield of shallot bulbs. There is no significant difference between cow manure and goat manure. Trichoderma inoculation has not had a significant effect on the growth and yield of shallots

One of the recommended concepts of organic agriculture is the use of organic fertilizers and minimizing the use of inorganic fertilizers in farming activities or crop cultivation. Manure is one of the organic fertilizers that are often used as fertilizer, one of which is goat manure. In addition, there are several types of household waste that can be used as liquid organic fertilizers such as the waste rice washing water that can be applied to plants. The research objective were to determine the effect of giving rice washing water waste and manure to the growth and yield of mustard plants. This research was conducted from February to April 2017. This study used a randomized block design with two factors consisting of 16 treatments and repeated three times. The first factor isto control rice washing waterwith a concentration of 10, 20 and 30 ml/liter of water and the second factor is manure consisting of control, manure 5, 10 and 15 grams. This study uses quantitative data analysis techniques. Analysis of quantitative descriptive data used is plant height and number of leaves.Observation results of plant height showed that the highest average of plant height was experienced by 20 ml/liter rice washing water and 15 goat manure treatment. Likewise, the average number of leaves of mustard plants was not significantly different from the treatment of rice washing water, but the number of leaves in mustard plants was not significant. The results showed there were no significant interactions between the concentration of rice washing water and manure doses on growth and yield of mustard greens The rice washing water did not have a significant effect on plant height and number of leaves. The difference in the results of this study was thought to be caused by differences in the types of rice used.

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. The results of this research were the best herbafarm POC on the treatment of     4 ml/liter of water that was on the parameters of plant height of  33,56 cm, leaves number  as much as 30. 63 blades, total dry weight of crop 9.99 g, number of tubers per family of 8.13 fruit, tuber diameter  of 20.26 mm, tuber length of  34.55 mm, fresh tuber weight per family of 32.57 g, tuber water content of 114.54 g and Weight of tuber per hectare 8.68 ton.ha-1.
