| ABSTRACT Two experiments were conducted in different areas of the Rafael Fernandes Experimental Farm, located in Lagoinha district, 20 km from Mossoró municipality (RN), in the period from June to September of the years of 2015 and 2016 with the objective of evaluating and estimating agronomic and economic feasibility indicators of cowpea-vegetable as a function of amounts of hairy woodrose (Merremia aegyptia (L.) Urb.) biomass incorporated into the soil in two crops. Treatments consisted of the following amounts of hairy woodrose biomass: 20, 35, 50 and 65 t ha-1 on a dry basis. The cultivar of cowpea-vegetable planted was “BRS Itaim”. The evaluated characteristics were: length of green pods, number of green pods per m2, productivity and dry mass of green... |

| The Ceres-Maize model was to study water consumption and profitability of maize crop at three growing seasons, for two regions of Minas Gerais, Brazil, for establishing and evaluating the necessary database for the use of this model. Cultivar BR201 was used to evaluate conduction distinct strategies of the crop, at the location of Sete Lagoas and Janauba. Treatments consisted of conduction of irrigated and non-irrigated crops during the growing seasons (15 May to 15 October and 15 December) and two frequency levels of water application: high (central pivot) and medium (conventional sprinkler irrigation). The simulation results have shown that the use of these models as complementary tools to conventional trials and the information presented helped on... |
