Abstract

Successive crops can increase the productivity and the economic efficiency of the vegetable production. Their success depends on the correct choice of suitable species and varieties in each area. Many authors have shown positive associations between the crops in succession but they also shown some types of crops that presents incompatibilities, caused by plants health issues, insufficient mineral supply, or allelopathic effects. In particular, it can be discussed on the negative relationship between species of the Chenopodiaceae Family (Becker-Dillingen, 1965, Hösslin et al., 1964) as well as the positive allelopathic effects between the species of the Brassicaceae Family (Jimenez-Ossorino and Gliesman, 1987). There have been studied two root crops: radish and red beet. These kinds of crops are finding favorable growing conditions in the pedoclimate of Bistrita County, and they were preceded in the same season by lettuce, spinach, small radish and spring onion. Thus there were eight experimental variants, arranged in randomized blocks of three repetitions each. The experiments were conducted between 2000 and 2001 on the experimental crop area owned by Bistrita’s Agricultural College.
