The Minang Bangkit Merbabu Farmer Group use organic materials and produce their own liquid organic fertilizer. This liquid organic fertilizer is made of varied ingredients: rabbit urine, cow's milk, free-range chicken eggs, palm sugar, coconut water, pineapple, shrimp paste, bamboo roots, ginger, and turmeric. Composting is strongly affected by pH and aeration method. Liquid organic fertilizer made by farmers usually have an initial pH of around 3.7. This mixture was usually composted using semi-anaerobic method. Through this study, we wanted to find out whether different methods of aeration and addition of rabbit urine would result in different liquid organic fertilizer quality. The quality of liquid organic fertilizer includes C-organic, total nitrogen, total phosphorus and total potassium. The experiment was designed as a factorial randomized block design. There were 2 factors tested: rabbit urine volume and aeration method. There were two levels of rabbit urine volume : original and modified ones. There were three levels of aeration method: aerobic, semi-anaerobic, and anaerobic. In total, there were six treatments and four replication for each treatment. The results of the analysis showed that composting with the aerobic method at the original rabbit urine volume could increase the concentration of nutrient content so that it gave the highest yield. It is different from composting at a modified rabbit urine volume, because the highest yield is in the anaerobic method. Keywords: aerated, organic, rabbit urine volume

The research aimed to find out the efforts to produce off-season orange fruit and increase the quality of fruit through the application of potassium nitrate and agrodyke organic fertilizer. The study used a factorial randomized block design with 2 treatment factors. The first factor is the flower induction application using potassium nitrate (K) consisting of 3 levels, namely (K0 = 0 g/tree), (K1 = 20 g/tree), and (K2 = 40 g/tree). While the second factor is the application of agrodyke organic fertilizer (P) consisting of 4 levels, namely (P0 = 0 g / tree), (P1 = 15 g/tree), (P2 = 30 g / tree) and (P3 = 45 g/tree). There are 12 combination treatments and each of them is repeated 3 times so that 36 tree plants are needed. The results showed the interaction between potassium nitrate treatment with agrodyke organic fertilizer treatment had no significant effect on all observed variables. Potassium nitrate treatment and agrodyke organic fertilizer can significantly improve the quality of orange citrus fruit out of season physically. In the treatment of potassium nitrate 40 g/tree, the weight of the harvested fruit per tree was obtained, the weight per fruit and the highest fruit diameter were 13703.90 g; 99.92 g and 6.81 cm or an increase of 62.24%; 16.32% and 9.49% compared with no treatment of potassium nitrate which is 8446.60 g; 87, 42 g and 6.22 cm.

Silicon (Si) and biostimulant management have been proposed techniques to reduce the impacts of abiotic stresses and to increase the productivity of several crops, however, there are still few concise results of the management of this crop. The objective of this work was to evaluate the effects of biostimulant and silicon treatments on isolated or mixed applications on mineral nutrition, yield and fiber quality of two cotton varieties. For this, an experiment was carried out in a randomized block design in the municipality of Luís Eduardo Magalhães-BA, in a 4 × 2 factorial arrangement, with four replications, in which four biostimulant treatments (control, without application; Si; biostimulant; and Si + biostimulant) were evaluated in two cotton varieties (FM 954GLT and FM 983GLT). The nutrient content of leaves, relative water content, electrolyte leakage, fiber yield, and quality were evaluated, the data collected were submitted to the F test and means were compared by Tukey at 5% probability. At the end of the experiment, it was verified that the management of Si and biostimulants increase the integrity of the cell wall, the association of Si + biostimulant increases the levels of N, Fe and Si foliar and reduces the levels of B and Mn, and do not influence on yield and fiber quality.

On some coffee plantations in Lahat Regency South Sumatra, in some places the farmers did not apply agricultural practices, such as tillage, conservation practices, and fertilizers. Many researches have been done to study about effects of organic fertilizer on soil nutrients content and plant growth as well as and the impacts of terrace on soil water content, run-off and erosion. However, there was less research in the highland area. Whereas the possibilityof run off, erosion and nutrient leaching the high land area was high. Thus, it was important to apply terrace and organic coffee pulp in this farm. The aims of this research were to determine the effect of terrace and organic fertilizer on run off and soil erosion, nutrients loss and nutrient content in coffee leaves. Terrace system and organic fertilizer were applied on a one year old coffee plantation in Lahat Regency. Before the treatment applied,coffee pulp as organic fertilizer was decomposed in the chamber for about 2 months. The experiment was conducted in factorial in a Randomized Block Design with two factors. The first factor was coffee pulp compost (0, 3, and 6 Mg ha-1), and the second factor was type of terrace (without, individual, and bund terraces). The size of each plot was 2 m width and 10 m length. Data was analysed by using LSD (Least Significant Different) test. The resultshows that bund terrace reduced runoff and erosion significantly up to 79% (for run off water) and 78% (for eroded soil) compared to without terrace. Organic fertilizer did not affect run off and soil erosion. This may be caused by properties of coffee pulp compost which were fine particulates and the dosages of application were too low to cover soil suface. Bund terrace decreased significantly N, P, K nutrients in soil loss (sediment). The amount of N losswas reduced from 3.37 kg ha-1 per four months (without terrace) to about 0.75 kg ha-1 per four months (bund terrace). Terrace and organic fertilizer did not affect significantly nutrients content in the leaves, but P-content was low without organic fertilizer addition. It is suggested to apply bund terrace and higher organic fertilizer dose on the coffee farm, and further experiments when harvesting the yield (berries) are needed for the second year oldcoffee farm.Keywords: Coffee, compost, erosion, nutrient, pulp, terrace

Food and nutrition are basic requirements for the promotion and protection of health. In addition to ensuring the availability of calories for consumption, it is necessary to improve the access to the variety of nutrients offered to the population. The consumption of brown sugar inserts nutrients into the feeding, once it is produced only by the evaporation of the existing water in the sugarcane broth, thus maintaining all the original constituents of the plant. To evaluate the influence of organic and conventional fertilization in the nutritional quality of the brown sugars, a test was conducted with six fertilization systems, in a completely randomized block design with four repetitions. The sugars produced were analysed regarding the contents of the nutrients Fe, Zn, Mn and Cu and the toxic elements Pb and Cd. The results showed that the different fertilization systems influenced the content of the minerals present. Although small, the differences were statistically significant and the treatments provided sugars with nutritional characteristics, with an advantage for the totally organic sugar (using organic fertilizer and corrective) which, in addition to environmental issues, did not present lead contamination.

This work aimed to evaluate the technical feasibility of lettuce, Indian spinach and taro intercropping under organic fertilizer. The experiment was performed at Água Limpa Farm, belonging to the University of Brasília, located in Brasília - DF, from October 2014 to June 2015. A completely randomized block design with seven treatments and four replications was used. Each experimental plot had 18 m2 (4.5 m x 4.0 m), totaling 28 plots. The following treatments were assessed: lettuce monoculture, Indian spinach monoculture, taro monoculture, lettuce/Indian spinach intercropping, lettuce/taro intercropping, Indian spinach/taro intercropping, and lettuce/Indian spinach/taro intercropping. In all treatments, the following spacings were used: 0.25 x 0.25 m (lettuce), 1.0 x 0.6 m (Indian spinach), and 1.0 x 0.3 m (taro). Crop production was evaluated from sample plants taken from the central part of each plot. Two harvests of lettuce, two of Indian spinach and one of taro were carried out during intercropping.  In the first cycle, lettuce highest mean yield values were observed in the lettuce monoculture (3.5 kg m-2) and lettuce/Indian spinach intercropping (3.4 kg m-2). The crop reached the commercial size in both production cycles, except when intercropped with Indian spinach in the second cycle. The highest Indian spinach mean fresh mass was recorded in the lettuce/Indian spinach intercropping (974.7 g plant-1; first harvest) and monoculture (327.5 g plant-1; second harvest). The yield of taro rhizomes was significantly higher when intercropped with lettuce, showing a mean value of 16.8 kg m-2. The intercropping arrangements with lettuce increased yield of nonconventional vegetables. The conventional and nonconventional vegetables’ intercropping technique increased species diversity in the area without interfering in the agronomic performance and quality of the crops.

This research aims to know the effect interaction of application of types and different dosage of organic fertilizers on production and fruit quality of melons on peatlands, effect of application of types and different dosage of organic fertilizers on production and fruit quality of melons on peatlands, and the agronomic efficiency of the use of several types and different dosage of organic fertilizers on production of melons on peatlands. This research design was used as a Randomized Block Design (RBD) consists of two factors with 4 replication. The first factor consisted of types of organic fertilizer (P) i.e. chicken manure (PA), guano manure (PG), and cow manure (PS). The second factor consisted of fertilizer dosage (D) i.e. 0 tons ha-1 (without fertilization, called control), D1 = 15 tons ha-1, D2 = 30 tons ha-1 and D3 = 45 tons ha-1. The data obtained by analysis of variance (ANOVA) or F test at a = 5% and 1% levels to determine the effect of treatment was tested further by HSD (honestly significant difference) testat the level of 5%. The result shows that the interaction type of organic fertilizer and the dosage of organic fertilizer treatment significant effect on the weight of the melon. Chicken manure is the best organic fertilizer on the size and quality of the melon. Dosage of 45 tons ha-1 organic fertilizer gave the highest results but it was not significantly different with a dosage of 30 tons ha-1. The use of chicken manure fertilizer of 30 tons ha-1 is more efficient in agronomy in increasing melons yield on peatlands.
