Componentes de produção e qualidade do óleo de duas cultivares de gergelim em função da adubação orgânica e mineral em um neossolo flúvico

Abstract

In the culture of sesame (Sesamum indicum L.) the average yield is around 650 kg ha 1 , but his production potential of 1,500 kg ha-1 with appropriate program of fertilization and water availability. The objective of this experiment was to evaluate the influence of organic and chemical fertilizers on yield components and oil quality of two cultivars of sesame: “BRS Seda” and “CNPA G4”. The experiment was conducted on a family farm in Rosario town in the municipality of Caxias, MA. The soil in the area is classified as Neossolo Flúvico. We used the design in randomized blocks with 12 treatments in a factorial (6 x 2), being six nitrogen sources: pies and cotton castor bean; cattle and goat manure, ammonium sulfate and the witness, as well as two varieties of sesame: BRS Seda e CNPA G4 (BRS 196). There was positive significant effect sources of fertilization on yield and sesame varieties on the growth variables and weight of 1000 seeds. There was formation of four treatment groups, in the one group, BRS Seda cultivar fertilized with goat manure excelled, showing better performance on the characteristics of growth, production and productivity. Considering the increasing oil yield, the goat manure can be recommended for varieties of sesame “BRS Seda” and “CNPA G4”.
