Vermicompost: alternative to urea in basil seed production

Abstract

Purpose -The purpose of this paper is to evaluate the effects of two vermicompost and urea on basil (Ocimum basilicum L.) variety Catamarca INTA (wide leaf) seed production, observing the evolution of the inflorescence and seed coloration. Design/methodology/approach -Treatments consisted of 50 per cent vermicompost from rumen content: 50 per cent soil (RCV); 50 per cent vermicompost from rabbit manure: 50 per cent soil (RMV); urea 100 kg/ha and soil as control. On three dates the authors determined the total number of inflorescences, harvested inflorescences and number of whorls with black seeds. In the final cycle the authors determined the weight of 1,000 seeds and the number of harvested seeds. Findings -In general, vermicompost produced better results (po0,0001): the total number inflorescences and whorls with black seeds and the number of seeds produced were significantly higher in vermicompost compared with those under the urea and control treatments. There were no significant differences in the weight of 1,000 seeds. Social implications -The use of chemical fertilizers causes environmental pollution, produces negative effects on human health and contributes to the depletion of non-renewable natural resources. Originality/value -These renewable amendments (vermicompost) constitute a sustainable alternative to the use of urea for inflorescence production and mature basil seed production.

Vermicompostaje: I avances y estrategias en el tratamiento de residuos sólidos orgánicos

“…An alternative of transforming organic waste, is the production earthworm humus, proposal ecological the use of chemical fertilizers (Cabanillas et al, 2013). The vermicomposting is called to make the second green revolution for generating organic fertilizer for use in the production of healthy food (Sinha et al, 2010b;Sinha et al, 2010c).…”

Addition of alternative materials to ceramic slabs

“…In the rural areas, the rice-growing sector stands out among the ones that have been worried about the environment. In agriculture is the pollution produced by solid waste plants and animals, but which may be reusable in other activities [13]. In the case of the rice sector has been implementing environmental impact reduction procedures, since they come from productive system externalities [14].…”

Eficiência das larvas de besouro coprófago na compostagem do esterco de coelho

“…As minhocas processam o esterco de coelho (MOLINA et al, 2013) e o vermicomposto produzido tem apresentado bons resultados na produção agrícola (CABANILLAS et al, 2013). Gómez-Brandón et al (2013) relataram a capacidade das minhocas em processarem esterco de coelho a partir de contínua oferta desse insumo puro e confirmaram, com base no perfil de fosfolipídios e nas medidas da atividade microbiana, alto grau de estabilização do produto final, cujo aspecto é fundamental no manejo orgânico do solo.…”
