Doses of bovine manure in the development of intercropped crops

Abstract

The present work presents discussions about an experiment carried out in beds with dimensions 2.00 X 1.00 m, which were prepared manually and using organic fertilization with cattle manure in the cultivation of some species of vegetables. And had as field of experience the experimental area of the Agroecological station of the Federal University of Recôncavo da Bahia (UFRB) in Cruz das Almas-BA, between June and August 2018. This was conducted in blocks using four treatments, T1: chili, scallions and pepper + 0.0 cattle manure; T2: Chili, scallions and pepper + 6 kg of bovine manure (20 t ha-1); T3: Chili, scallions and pepper + 12 kg of bovine manure (40 T ha-1) and T4: chili, scallions and pepper + 18 kg of bovine manure (60 t ha-1), with six plants of each species in each site with spacing of 0.6 x 0.3. The seeds of the studied species were obtained at home farming of the commercialization of agricultural products. With the same, it was possible to observe the importance of organic fertilization in the plantation, but also realize the need to know how to dose the amount of nutrients contained in it in order to correctly handle this residue in order to ensure the benefits necessary for the development of the soil and consequently of the products cultivated in it. Specifically in this study, it was proved that the use of 6 kg of bovine manure was not sufficient to meet the nutritional needs of the species studied or the process of mineralization of organic matter occurred slowly, slowing the growth of the vegetables. When 18 kg the number of leaves was significantly reduced this behavior occurred due to the high accumulation of nutrients that caused antagonistic effect, that is, the law of decreasing increments occurred with reduction in the number of leaves acquired With the use of 12 kg, which is considered a better quantity for the adequate evolution of plantations in tests. Finally, the data indicate the importance that bovine manure brings to organic production from its respective influence during the experiment that positively caused the growth of the vegetables tested with higher height when Used 12 kg of manure for both species of vegetables tested.
