ABSTRACT Garlic (Allium sativum) is normally grown under conventional tillage (CT) with soil being excessively mixed by plowing and harrowing operations that degrade soil structure, increase production costs, and increase environmental contamination. Alternatively, cover crops can be grown and their residues placed on soil surface, enabling garlic to be grown under no-tillage (NT) system. However, for subtropical climate there is little information on the impacts of tillage systems and cover crop species, particularly of their decomposition process and nutrients release, […]

ABSTRACT Corn and garlic are important crops to Curitibanos region (state of Santa Catarina – Brazil), often planted in alternate cropping seasons. Production costs are high, especially due to N fertilizer, since they are highly demanding in N. In addition to reducing economic costs, the search for environmentally sustainable technologies has stimulated the study of interactions between plants and growth-promoting microorganisms. Rhizobacteria, e.g., Bacillus sp., have been presenting as growth-promoting microorganisms. Five isolates of garlic rhizosphere from 27 individuals of […]

ABSTRACT The recommendations of nitrogen (N) fertilization in garlic are still based on different varieties of the current types that are infected with phytopathogenic virus. There are several methods for recommendation of nitrogen (N) fertilization in garlic, but there are no enough methods for N diagnosis in garlic obtained by meristem culture. The objective of this work was to evaluate methods for diagnosing the nutritional status of virus-free garlic subjected to N doses through the use of a specific NO3– […]

Estudaram-se respostas à adubação fosfatada pelo alho vernalizado cv. Roxo Pérola de Caçador em cinco solos com diferentes classes texturais, com e sem adubação orgânica, visando contribuir para o estabelecimento de curva de calibração para fósforo extraído por resina de troca iônica. Foram instalados dois experimentos entre maio e outubro de 1995 e 1996, em vasos (16 L), em casa de vegetação telada do Departamento de Ciência do Solo da Faculdade de Ciências Agronômicas/UNESP, município de Botucatu (SP). Cada experimento […]
