| The aim of the study was to assess the effects of groundnut shells on soil properties, growth and yield of maize. The study was carried out in Jalingo, Taraba State, North-Eastern Nigeria in July, 2019. Treatments in the study were four doses of groundnut shells (0.0, 2.5, 5.0 and 7.5 t ha-1); arranged in a randomized complete block design, replicated four times. Each plot was 2.0 m × 2.0 m with 0.5 m gap between the plots and replicates. Crushed groundnut shells were applied on a dry matter basis at the rates of 0, 2.5, 5.0 and 7.5 t ha-1 28 days before planting maize. Seeds were planted on prepared land treated with crushed groundnut shells. Soil properties were determined at harvest, maize growth parameters were determined at 50% flowering and maize... |

| The application of organic fertilizer to the soil is considered as good agricultural practice because it improves the fertility of the soil and plant quality. The aim of the study was to produce compost tea using poultry droppings, cow dungs and water leaf (Talinum triangulare) in a ratio 5:5:1 and evaluate its effects on soil properties, growth and yield of Amaranthus hybridus. The study was carried out in Jalingo, Taraba State, North-Eastern Nigeria in July, 2019. The experimental variables include control (no treatment), 1 kg of compost per 10 L of water compost tea, 1 kg of compost per 20 L of water compost tea, 1 kg of compost per 30 L of water compost tea, 500 kg ha-1solid compost and 500kg ha-1 NPK fertilizer. The treatment combinations were done in... |

| Leafy vegetables such as lettuce grown under different production systems may accumulate different concentrations of nitrate which may reach to the levels potentially toxic to humans. Moreover, nitrate accumulation varies in various plant parts and physiological age of the plant. Therefore, to determine the effect of production system and harvesting stage on nitrate accumulation and quality of butterhead lettuce, a study was conducted considering two lettuce production systems namely hydroponic and organic, and four different harvesting stages such as 35, 38, 41 and 44 days after transplanting (DAT). The experimental design was complete randomized design (CRD) with four replications. Hydroponic and organic systems performed similar in terms of yield,... |

| Rising global demand for natural products whose production is harmless to the environment has stimulated the development of natural cosmetics and, within this category, organics (95% organic raw materials). The image of environmentally friendly production is one of the strongest attractions of organic products. Lip balm is a cosmetic product similar to lipstick whose purpose is to prevent lip dryness and protect against adverse environmental factors. The product's characteristics are: resistance to temperature variations, pleasant flavor, innocuousness, smoothness during application, adherence and easy intentional removal. This work involved the development of a lip balm formulated with certified organic raw materials and the execution of stability tests:... |

| The efficiency of composting processes with and without the addition of Californian red worms (Eisenia foetida) was evaluated, using manure of dairy cows to generate organic fertilizer. Several parameters were assessed as physio-chemical indicators of maturity, such as temperature, pH, C/N ratio, phytotoxicity and macro and micronutrients at 25 and 54 ws (mature and stored products, respectively). A linear model was used in the statistical analysis, with four replicates that included as fixed effects, the composting systems and time. At 25 wk, both systems reduced the C/N ratio to values of 15.5 in vermicompost and 17.1 in semi-compost. The content of total N, N-NO3, Ca and some micronutrients also increased. K and Na concentrations were higher in the... |

| The objective of this study was to evaluate the influence of vitamin C (VC), vitamin E (VE), and two selenium sources on the performance, yield, and composition of Nile tilapia fillet. The experiment was conducted in a completely randomized design consisting of six treatments with the addition of 100, 200, and 400 mg kg-1 VC and VE and 0.1, 0.2, and 0.4 of two sources of selenium. Each treatment had five replicates of 30 fish each. The diet with 200 mg kg-1 VC and VE + 0.2 mg.k-1 organic selenium resulted in weight gain, length gain, and feed conversion ratio similar to that of the treatment with 400 mg kg-1 VC and VE + 0.4 mg kg-1 organic or inorganic selenium. The addition of organic selenium to the diet improved the weight gain and feed conversion ratio... |

| El estudio se realizo en el Ejido las Piedras, Municipio de Huimanguillo, Tabasco, México. Tuvo como objetivo estimar rendimiento y analizar costos de producción en el cultivo de Maíz sembrado en el ciclo primavera verano de 2008. Se realizaron muestreos de suelo para analizar la fertilidad antes y después de la cosecha, muestreos de lombriz de tierra para saber el número de individuos presentes en el suelo de las parcelas en estudio y la estimación de costos de producción se uso para saber cuánto gasto cada productor en el cultivo de Maíz (Zea Mays L.). Las parcelas en estudio fueron cuatro; La primera parcela fue sembrada en suelo acahualado dándole manejo químico, la segunda siembra fue realizada en terreno barbechado y se le dio manejo... |

| En el período 2003-2007 en Nicaragua, se hizo un esfuerzo para lograr la producción de carne orgánica y mejorar la situación económica y social de los productores nicaragüenses, aprovechando los buenos precios de la carne orgánica en el mercado internacional. Los pocos productores que lograron producir este tipo de carne, encontraron cerrados los canales de comercialización. El esfuerzo en el área productiva, el sacrificio de los productores, se perdió. El objetivo de este trabajo es describir el proyecto, explicar las causas de los resultados y comparar dos modelos: el de la ganadería orgánica en sus diferentes etapas y el de la ganadería convencional en Nicaragua. La comparación se efectúa en condiciones de trópico húmedo y alrededor de dos variables... |
