A demanda por olerícolas de qualidade e saudáveis torna necessário buscar novas técnicas de cultivo, ou ainda obter maior eficiência e economia nas já conhecidas. Conhecendo a grande demanda e extração de nutrientes pelas hortaliças, o presente trabalho objetivou estimar o efeito de vermicompostos e de cinza de ossos, na produção de rúcula e de rabanete. Os resíduos orgânicos utilizados para a produção dos compostos foram: esterco bovino e de galinha. Foram utilizadas minhocas da espécie Eisenia foetida para produção do húmus. A cinza de ossos foi obtida pela queima de uma carcaça bovina. O delineamento experimental foi o inteiramente casualizado com 12 tratamentos formados da combinação de quatro diferentes formulações, três doses e três repetições. O efeito dos tratamentos foi avaliado para o rabanete cultivar ‘Crimson Gigante’ e a rúcula cultivar ‘Cultivada’ em ambiente com 50% de sombreamento. Para o rabanete, foram avaliadas as seguintes características: massas fresca e seca das raízes e parte aérea; comprimento das raízes fasciculadas; comprimento e diâmetro das raízes tuberosas; número de folhas e área foliar. E para a Rúcula foram avaliados: número de folhas; comprimento das raízes; área foliar; massas fresca e seca da parte aérea e raízes. O húmus a partir de esterco bovino permite melhores respostas para o rabanete, a 200 t ha-1. Já para a cultura da rúcula, é recomendado o uso de 200 t ha-1 de vermicompostos a partir de esterco bovino e de aves juntamente com farinha de ossos.

Objetivo: Caracterizar el efecto de un biofertilizante a base de lixiviado vermicomposta (VCL) en cultivos de relevancia en México, formulado en combinación con: i) fertilizante químico (NPK), ii) una mezcla de dos productos comerciales con microorganismos promotores del crecimiento de las plantas y hongos micorrízicos arbusculares (HMA) y iii) melaza. Diseño/metodología/aproximación: Cuatro tratamientos fueron evaluados: T1 (VCL, microorganismos, sin melaza y sin NPK), T2 (VCL, microorganismos, sin melaza y con NPK), T3 (únicamente con NPK) y T4 (VCL, microorganismos, melaza y sin NPK), distribuidos en 128 macetas con ocho especies de cultivos (tomate, chile, sorgo, frijol, chícharo, maíz, calabaza y sandía) (4 réplicas por cultivo) bajo condiciones de invernadero. Después de 6 semanas, se midieron la altura de la planta y número de hojas. La significancia estadística se determinó mediante análisis de varianza (ANOVA) y la prueba de Tukey. Resultados: Los Tratamientos T1 y T2 presentaron los mejores efectos en la mayoría de las plantas. La sandía mostró una mejor respuesta a T3 y en maíz no se observaron efectos significativos. T4 mostró una influencia negativa en el desarrollo de todos los cultivos, atribuido a la incorporación de melaza. Limitaciones del estudio/implicaciones: El estudio se llevó a cabo en un corto período de tiempo y no fue posible evaluar la producción de fruto. Hallazgos/conclusiones: El VCL combinado con bacterias promotoras de crecimiento y HMA, tienen efectos positivos en el crecimiento de tomate, chile, sorgo, chícharo y calabaza; pudiendo reducir la fertilización química en un 35% sin disminuir el rendimiento. Palabras Clave: Biofertilizantes, Eisenia foetida, hongos micorrízicos arbusculares, lixiviado de vermicomposta, microorganismos promotores del crecimiento de plantas.

The objective of the present investigation was to evaluate the physical characteristics of the vermicompost and the quality of the purine of the red Californian (Eisenia foetida) using different substrates of feed for these worms. For this purpose, nine treatments were studied: 75% African palm rachis + 25% cattle manure, 50% African palm rachis + 50% cattle manure, 25% African palm rachis + 75% livestock manure, 50% manure of cattle, 50% of manure of cattle, 25% of manure of cattle, 50% of manure of cattle, 50% of manure of cattle, 50% of rach of coconut + 50% of manure of Livestock, 25% coccus rachis + 75% livestock manure. The substrate made up of 50% of rachis of coconut and 50% of livestock manure can be used in nurseries or nurseries for being the one that registered a value of pH 7.3 plus the closest to the neutral compared to the others, besides this (75% of oil palm rachis and 25% of cattle manure) showed a higher content of humic and fulvic acids (0.87 and 0.45 p / p, respectively), compounds that are important for agriculture by stimulating plant growth, in addition to this reflection 0.06% sulfur content, 4.0 ppm boron, 7.0 ppm copper, 47.5 ppm iron, 6.0 ppm manganese, with a presence of microorganisms of the species Trichoderma, Penicillium, Cladosporium sp. in amounts of 1.91x105 UFC / ml, however in this substrate was obtained between 13.3 and 43.5% less liquid slurry in Comparison with other treatments.

Bacteria are an unavoidable component of the natural earthworm diet; thus, bacterial diversity in the earthworm gut is directly linked to decomposition of organic matter and development of the surrounding plants. The aim of this research was to isolate and to identify biochemically and molecularly the culturable bacterial microbiota of the digestive tract of Eisenia foetida. Earthworms were sourced from Instituto de Reconversión Productiva y Bioenergética (IRBIO) and Colegio de Postgraduados (COLPOS), México. Bacterial isolation was carried out on plates of Brain Heart Infusion (BHI) culture medium. Fifty six and 44 bacterial isolates were obtained from IRBIO and COLPOS, respectively. The population was composed of 44 Gram-negative and 56 Gram-positive isolates. Over 50 % of the bacterial isolates were rod-shaped cells. The 16S rRNA gene was sequenced and nine genera were identified in worms from IRBIO (Bacillus, Paenibacillus, Solibacillus, Staphylococcus, Arthrobacter, Pantoea, Stenotrophomonas, Acinetobacter and Aeromonas) and six in worms from COLPOS (Bacillus, Paenibacillus, Stenotrophomonas, Staphylococcus, Acinetobacter and Aeromonas). Bacillus was the predominant genus, with eight and six species in the oligochaetes from IRBIO and COLPOS, respectively. The most represented bacteria in the worms from both sites were Bacillus sp. and B. subtilis. The predominance of Bacillus was probably due to spore formation, a reproductive strategy that ensures survival and dispersion in the soil and oligochaetes digestive tract. The gut of E. foetida not only harbored bacterial species of agronomic importance but also species potentially pathogenic for humans (Staphylococcus warneri, Pantoea agglomerans and Stentrophomonas sp.). The larger bacterial diversity in worms from IRBIO could be due to their feeding on cattle manure, which is a rich source of bacteria.

The decay of leaf litter by microflora and fauna furnish nutrient supply to the soil and also uphold ecological sustainability. Applying of proper technique and exploring of result provides information for the betterment of agricultural system. Vermicomposting of Sandalwood (Santalum album) leaf litters were studied with an emphasis of physio-chemical deviation during the process and also compared with 100 % cattle dung. Obtained result explore that temperate of 50 % leaf litter (LL) and 100 % cattle dung (CD) was slightly elevated (37ºC ±1 ºC and 35ºC ±1 ºC respectively) at beginning phase and later came down to ambient level (20ºC±1 ºC). The total organic carbon (TOC) exhausted 44 % in 50 % LL Vermicomposting mixture while 70 % in 100 % CD during the process. At the final stage, TOC found more in 50% LL as compared to 100% CD. Nitrogen content was found 1.02±0.1 in 50 % LL and 0.88±0.1 in 100 % CD at the initial phase but after completion of Vermicomposting, their level was increased up to 40 to 44 %.  pH was also measured during vermicomposting and found 7.2±0.1 in 50% LL while 8.4±0.1 in 100% CD at the initial phase. The at the end of process pH raised and set up to 8.2 ±0.1 in 50% LL while in 100% CD it was found 8.0 ±0.1.
