Produtividade de mandioca brs novo horizonte em função do tipo adubação verde em um período de 09 meses

Abstract

Cassava is mainly cultivated using traditional land preparation methods. Due to slow growth in the initial hase, erosion problems can worsen, which can make production unsustainable in several regions. One way to reduce erosion caused by water is to improve soil cover through intercropping. For this reason, the objective of this work was to evaluate the effects of using different types of cover crops/green manure on the productivity of the BRS Novo Horizonte cultivar over a period of nine months. The work was conducted in a Direct Planting area, within the vegetable experimental farm within the Federal University of Bahia – UFRB. Five soil cover plant treatments were used: 1. Corn (Zea mays) intercropped with Crotalaria juncea (Crotalaria juncea), 2. Corn (Zea mays) intercropped with Dwarf pigeon pea (Cajanus cajan), 3. Corn (Zea mays) intercropped with Mucuna preta (Mucuna pruriens), 4. Millet (Pennisetum glaucum) with Crotalaria juncea (Crotalaria juncea) 5. No treatment – spontaneous plants (control). The parameters evaluated were: weight of the upper third, root diameter, number of roots, root length, root weight, root production and productivity. The data were subjected to the Tukey test at 5% significance. The result obtained showed that there was no significant difference between the treatments, reaching an average of 37.09 Mg.ha-1. Proposing that the consortium of cover crops combined with the Direct Planting System is an efficient alternative for increasing productivity and soil conservation.
