The objectives of this work were to a) determine vermicompost effect on bulbification dynamics in terms of garlic (Allium sativum L.) bulb dry weight and sucrose metabolism and b) evaluate the impact of vermicompost on garlic bulb yield and quality. The treatments were soil (control) and 1 soil: 1 vermicompost (by volume). The use of vermicompost as a substrate caused early bulbing (18 to 20 days) and lengthened bulb filling period. Bulb filling period corresponded to an increase in the total soluble carbohydrates and a later modification in nonstructural carbohydrate distribution patterns regarding fructan (scorodose) metabolism. The vermicompost treatment increased scorodose accumulation, which was directly related to the harvest index, resulting in greater yield and bulb quality. Bulb quality was not modified in terms of bulb pungency and soluble solids content by the use of vermicompost.

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.
