| Based on the hypothesis that alternative substrates should improve the yield of lettuce crops by producing better quality seedlings, the objective of this work was to evaluate the effect of different substrates on the production of seedlings of this species, and their growth in the field. The study was in two stages. The first consisted of the production of lettuce seedlings, and the second assessed their development in the field. Four alternative substrates were tested, obtained by mixing together a sieved vermicompost from which all clumps had been removed, sterilized sand, charred rice husks and basalt powder. The commercial substrate, Plantmax HA®, was also tested. In the first phase, which was conducted in a completely randomised design with four... |

| Declining soil fertility is a challenge to sustainable agricultural production in sub-Saharan Africa with a case of Uganda. However, the large volumes of agricultural waste generated from pineapples can be converted into soil conditioners through vermicomposting. by the use of earthworms. Several types of agricultural waste have been studied extensively as vermicompost feedstock, but little work exists on pineapple waste. The objective of this study was to investigate the suitability of pineapple waste for vermicomposting. To achieve this, an assessment of the physicochemical properties of fresh, pre-composted pineapple waste, and the resultant vermicompost, and determination of the optimal feeding rate and stocking density were performed. The study... |

| ABSTRACT The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency index of nitrogen (N), phosphorus (P), and potassium (K) in organic fertilizers produced from cattle manure. The following treatments were evaluated in an incubation experiment under controlled conditions: soil without fertilizer (control); soil + beef cattle manure vermicompost; soil + beef cattle manure/straw compost; soil + beef cattle manure; soil + dairy cattle manure; and soil + vermicompost produced... |

| Vermicomposting is at suitable methods for stabilization and converting of sewage sludge into useful products. To investigate the effects of bulking material on vermicompost quality, an experiment was conducted in a factorial design with three replications. In this experiment, the final dried sludge in lagoons was mixed with bulking materials (woodchips, three leaves, and wheat straw) in four mixing proportion with swage sludge (0, 15, 30 and 45%, V/V). Chemical properties of bulking materials, sewage sludge, and produced vermicomposts were determined. Vermicomposts had relatively low pH and electrical conductivity (EC). The nutrients content of vermicompost, especially N, P, Fe, and Zn, were high. These properties showed its suitable quality for use in... |

| Rhizoctonia solani damping-off and root rot diseases are frequent in impatiens crops in Buenos Aires. Their control is based in fungicide use. In a sustainable nursery production, beneficial microorganisms that develop in organic amendments may suppress diseases and promote plant growth. The aim of this work was to evaluate the effect of different proportions of vermicompost on the growth and health of patience-plant (Impatiens wallerana). The experiment was carried out in a polyethylene greenhouse. Treatments were defined as follows: infested substrate, substrate, sterilized substrate, vermicompost, and vermicompost mixed with infested substrate at 75, 50 and 25% by volume. Seeds of I. wallerana were sown in plugs containing the different substrates.... |

| ABSTRACT VC (20%), TC (20%) and N:P:K fertilizer (farmer's practice) were used to determine the growth and yield attributes of bush bean (Phaseolus vulgaris), winged bean (Psophocarpus tetragonolobus) and yard long bean (Vigna unguiculata). Plants grown with VC (20%) produced the highest fresh biomass for bush bean (527.55 g m-2), winged bean (1168.61 g m-2) and yard long bean (409.84 g m-2). In all the tested legumes the highest pod weight, pod number, pod dry weight and pod length were found in the VC (20%) treatment. Photosynthetic rates in the three legumes peaked at pod formation stage in all treatments, with the highest photosynthetic rate observed in winged bean (56.17 µmol m-2s-1) grown with VC (20%). The highest yield for bush bean (2.98 ton... |

| Abstract The time of formation of mangosteen seedlings propagated by seeds can be considered as the biggest difficulty in the seedling production system of this species. Considering that the use of humic acids as a growth promoter has been well documented in some species, the objective of this work was to evaluate the growth of mangosteen seedlings in response to the application of humic acid (HA) doses extracted from vermicompost (0; 2; 20; 40; 200 mg C L-1). Growth rate was determined using the following variables: stem diameter, plant height, number of leaves, leaf area, stem dry matter, leaf dry matter, shoot dry matter, root dry matter, total dry matter and Dickson quality index . The dose 150 mg C L-1 was the one that approached the maximum values... |

| El trabajo tuvo como objetivo evaluar el desarrollo de dos diferentes portainjertos (C35 y Limón Volkameriano) en diferentes sustratos, las cuales estaban compuestos por tierra vega de río, compost, vermicompost y peat moss. Se emplearon plantas de un vivero certificado ubicado en Cazones, Veracruz. Se realizaron muestreos no destructivos periódicos (cada 30 días) a partir de los 90 días después del transplante (ddt) tomando como variables: altura de la planta y diámetro de tallo. Así también se midieron la tasa de crecimiento relativo y el índice de calidad. A los 180 ddt los tratamientos que contenían compost y vermicompost, los cuales tuvieron mejor porte y vigor, superaron en altura a los tratamientos con peat moss en los dos portainjertos,... |

| ABSTRACT: This research aimed to evaluate the mineralization of nitrogen (N) and to define the efficiency index (EI) of N after the addition of organic fertilizers based on cattle manure on the soil under laboratory conditions. A completely randomized statistical design with four replicates was used. The treatments were set as follows: T1) Soil (control); T2) Soil + vermicompost of cattle manure (CMV); T3) Soil + cattle manure and straw compost (CMS); and T4) Soil + cattle manure (CM). Experimental units were constituted by acrylic flasks with 5 x 5cm (height x diameter). Each flask was added with 135g of wet soil and 2.20, 2.45 and 2.27g of CMV, CMS and CM, respectively. Treatments were incubated at 25°C and the amount of mineral N from the soil (N-NH4+... |

| En el presente estudio se investigó el efecto de complementar turba a diferentes salinidades con vermicompost de excretas de borrego sobre la sobrevivencia, el crecimiento y la fotosíntesis de plántulas de tamarindo (Tamarindus indica), en un experimento en invernadero. Las plantas se cultivaron en sustrato de turba (peat moss) adicionado con 0, 20, 40, 60 y 80 mM de NaCl y complementado con o sin 10% (v/v) de vermicompost. Sin vermicompost, la sobrevivencia de las plantas fue de 20%) en el tratamiento con 80 mM de NaCl, pero con vermicompost la sobrevivencia fue de 85%o. Sin vermicompost el crecimiento de las plantas se redujo en dos veces a 20 mM de NaCl, pero con vermicompost no se encontró efecto inhibitorio. La fotosíntesis se redujo en las plantas en... |

| ABSTRACT The growing demand for animal protein is directly related to the feedlot system of animals and their assumptions, such as the waste management. The characterization of the final products becomes an important factor in decision making by one or by other process. The objective was highlight characteristics that fertilizers present due to the used of stabilization process, by the principal component analysis. For the manure stabilization we realized three aerobic processes, composting, vermicomposting and natural decomposition, and one anaerobic, the anaerobic digestion. These processes produced the compost, the vermicompost, the decomposed manure and the biofertilizer. Fertilizers produced were analyzed by means of seventeen chemical and... |
