Aplicação de cinza vegetal e esterco bovino em sistema de cultura orgânico de Raphanus sativus.

Abstract

Sustainability, nowadays, has had a great impact for all of us, due to its worldwide demographic growth, where all nations look for agreements in order to reduce damage caused to the environment. Mentioning damage, one example is vegetable solid waste, analyzed in this methodological research, and generated, abundantly, by industrial activities and disposed incorrectly. The present study aims at evaluating radish (Raphanus sativus) cultivation, in different doses of vegetable ash added with bovine manure. The soil was mixed with five treatments in different doses of ash, equal addition of bovine manure, as source of organic fertilization, in containers, numbering a total of ten repetitions, in such doses: T1=witness; T2= 10 g/dm-3; T3= 20 g/dm-3; T4= 30 g/dm-3; T5= 40 g dm-3 of ash, conducted in in a completely randomized design. The evaluation was achieved through agronomic variables: fresh and dry root plant mass and aerial part, root diameter, root length and aerial part and measurement of soil’s ph. Such parameters, which were analyzed, it was shown that the treatment T5= 40 g dm-3 of ash, was enough to obtain better and analyzed averages, resulting in an increase of vegetable attributes and chemical improvement of the soil.
