Plantas de cobertura no cultivo de beterraba (Beta vulgaris)

Abstract

The objective of this work was to analyze the effect of cover crops on beet cultivation. The experiment was carried out under field conditions in Alto da Serra - countryside of ​​Chapecó / SC. Millet cultivar ​Campeiro (​Pennisetum glaucum​) and crotalaria (​Crotalaria breviflora​) were sown broadcasting after soil correction and bedding preparation; cover crops were sown between January and February 2019 and the harvest occurred in the month April 2019. Beet seedlings were produced in the rural property, with trays in June 2019, in July the transplant was carried out to the field and in October of the same year was the manual beet harvesting. The experiment consisted of six treatments, in a 3 x 2 factorial scheme with four replications, the first factor consisting of different green coverings: crotalaria, millet and control (without cover and without weeds); the second factor consisted of two beet cultivars: ​Chata do Egito and ​Maravilha​, in a randomized block design. Crotalaria plants are superior to millet plants in relation to fresh mass production, however, they did not differ in dry mass. There was no interference from millet straw on total beet production and quality. There is no difference in the performance of the two beet cultivars under the cover of straw and without cover
