In Taiwan, castor meal (CM) is often used by farmers as an organic fertilizer for the supplement of plant nutrition. It can rapidly increase nitrogen availability for crops. However, the excessive application of CM will affect the ecosystem. This study was conducted to evaluate the optimum concentration of CM that can be used as a fertilizer for balancing crop production and soil ecosystem health (by considering earthworms). Pak choi was selected for the experiment. A randomized block design with three replications was used, with treatments consisting of five concentrations of CM (namely 25, 50, 100, 150, and 200 kg/0.1 ha) and fermented livestock compost 800 kg/0.1 ha, represented as CM25, CM50, CM100, CM150, CM200, and LC800, respectively. The results revealed that soil properties, leaf nutrient concentration, and plant traits, namely plant diameter, plant height, and fresh and dry root and shoot matter, improved with the increasing concentrations of CM, and CM100–CM200, and led to the highest production of pak choi which was equivalent to that with LC800. However, the weight of earthworms decreased as CM concentrations increased. The weight of earthworms was similar between CM25, CM50, CM100, and LC800. In conclusion, given the characteristics of high nitrogen as a fertilizer, the optimal dose of CM was 100–150 kg/0.1 ha for obtaining a balance between crop production and ecosystem safety.

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.

Soybean (Glycine max L.Merrill) is one of the main food commodities in Indonesia. The need for soybeans continues to increase in line with the increasing population of Indonesia. To overcome the problem of the gap between soybean production and consumption, efforts can be made to increase soybean production through fertilizers. Apart from fertilizers, mulching is an important component in efforts to increase plant growth and yield. Therefore, liquid organic fertilizer and organic mulch are the right innovations to be applied to support the growth and production of these soybean plants. The research method used was a randomized block design (RBD) with a factorial pattern with 3 replications, which consisted of 2 factors. The first factor was Liquid Organic Fertilizer (P) consisting of 3 levels, namely P1 (cow urine), P2 (goat urine), P3 (rabbit urine). The second factor was kinds of organic mulch with 3 levels, namely M0 (no mulch), M1 (straw mulch), M2 (husk mulch). The purpose of this study was to determine the effect of livestock bio urine and organic mulch on the growth and production of soybean (Glycine max. L,Merril). From the results of observations and calculations through analysis of variance, it can be concluded that the ones that give high production are the treatment of Rabbit Urine Liquid Organic Fertilizer and Organic Straw Mulch (P3M1).

An important aspect in the cultivation of vegetables is the quality of the product to be marketed, free from dirt and damage and the practice of mulching could be an option, but there is scarse information. The aim of this study was to evaluate the influence of mulching on the production traits of three cultivars of Pak Choi. The experiment was set up during March to May 2013 using a split plot randomized block design, with four replications. Soil cover treatments (white agrotextile, black agrotextile, black plastic, silver plastic, tifton straw and bare soil) were arranged in the plots, and three cultivars of Pak Choi (Green Pak Choi, White Pak Choi and Chingensai Natsu Shomi) in subplots. Height and diameter of shoots, number of leaves, fresh weight of the head and petiole, base diameter, dry weight of stem, petiole, and leaf were evaluated thirty-five days after transplantation. The total dry weight and leaf area were measured, and then we estimated the yield. There was a significant effect of soil cover and cultivar. In general, the cover with synthetic materials showed higher values on production of Pak Choi. The cultivar White Pak Choi was better adapted to the growing conditions, with an average yield of 57.78 t/ha.

ABSTRACT Nitrogen is essential for sustaining life on the planet, and it is the most important nutrient for obtaining high agricultural production. However, their use leads to the release of nitrous oxide with a global warming potential 296 times higher than the CO2 molecule, making it a challenge to reduce their use in agriculture. The objective of this research was to identify efficient popcorn inbred lines and responsive nitrogen use and exhibit a good expansion volume. For this, 29 inbred lines from the Germplasm Collection of Darcy Ribeiro North Fluminense State University (UENF) were evaluated at two contrasting levels of nitrogen availability (low and ideal) at two representative locations in the north and northwest of the state of Rio de Janeiro, Brazil, arranged in a randomized block design with three replicates. These inbred lines were discriminated against efficient use of nitrogen by multivariate GGE Biplot. Selective accuracy was close to 1, showing that the genotypes were enough to provide contrasting success in selection procedures. The first two main components (PC) retained 93.82% of the total variation, and PC1 furnished an information ratio (IR) that was unaffected by noise. L77 was the most unstable line, while P7, P2, P6, P3, P5, P4, P9, P10, P8, P9, L70, L74, and L55 were efficient and responsive. The GGE biplot method is recommended for the reliable identification of popcorn lines that are efficient and responsive to the use of nitrogen.

The use of inorganic fertilizers has an important role in increasing plant growth and production. But it also causes various problems such as decreasing soil organic matter, soil acidity, soil degradation, nutrient imbalance and increasing environmental pollution. Therefore, it needs to be balanced with the provision of organic fertilizers. A field experiment was conducted to study the effect of application of various doses of inorganic and organic fertilizers on N, P, K nutrient uptake and maize plant growth. The experimental design used was a randomized block design arranged in a factorial manner consisting of two factors. The first factor is the dose of inorganic fertilizer (A): 0, 150 and 300 kg ha-1 phonska and the second factor is organic fertilizer plus (P): 0, 10, 20 tons ha-1. The two factors were combined and each treatment combination was repeated three times. The data obtained were analyzed by analysis of variance at the 5% level of significance. The results showed that there was no interaction between the application of inorganic and organic fertilizers on the growth and nutrient uptake of N, P and K. However, the application of inorganic and organic fertilizers had a significant effect on all tested agronomic traits except for plant height. Nutrient uptake of N, P and K also increased significantly due to the application of inorganic and organic fertilizers. The balance of inorganic and organic fertilizer application increases the availability of nutrients as well as the uptake of N, P, and K nutrients by maize plants.

ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

The application of organic fertilizer, especially manures, for crop production has long-term effects for soil nutrients availability and improvement of soil structure. The improvement of soil properties involves interactions of various types of microorganism in the soil. The research aimed to study the effects of different types of manures on the diversity of functional soil microbes and its effects on organic green mustard production. The experiment was conducted at IPB organic research field, Cikarawang, Darmaga, Bogor, from April to June 2015. The experiment used a randomized complete block design with two factors; the first factor was types of manure, i.e. chicken, cow, and goat manures; the second factor was manure rates, i.e. 0 and 10 ton.ha-1, so there were six treatments in total, replicated three times. The results showed that chicken manure application resulted in a higher mustard green yield and soil-P content than application of goat manure. The addition 10 ton.ha-1 of manures increased C-organic, N, K, and C/N ratio in soil significantly, but mustard green production was not affected. The diversity of microbe population of the soil treated with all types of manures was high. The addition 10 ton.ha-1 of manures decreased the total number of microbes, but increased the number of cellulose-degrading microbes. The population of cellulose-degrading and phosphate-solubilizing microbes in the soil applied with cow manure was higher than those applied with the other manures.
