Resumen:
The objective of this study was to evaluate the effect of mineral and organic fertilization with castor
cake on production of two of sesame irrigated with domestic wastewater and water supply. For that,
sesame plants were grown in pots with a capacity of 20 L filled with sandy-loam soil and subjected to
treatment that resulted from the factorial combination of treatments that resulted from combinations of
two varieties of sesame (CNPA G3 and CNPA G4), five doses of castor cake in the substrate (0, 2, 3,
4 and 5 ton ha-1) and two qualities of irrigation water (water supply and wastewater), plus two
additional treatments with mineral fertilizer for each of the varieties (NPK + water supply and NPK +
wastewater). The crop was conducted until the end of the cycle when it was evaluated the height of
insertion of the first fruit, the number of fruits per plant, fruit weight and the weight of 100 seeds. The
results showed that the fruit had higher weight when irrigated with wastewater and fertilized with cake
of castor bean at a dose of 4 ton ha-1; regarding to production per plant, the best results were
observed for the variety CNPA G4 irrigated with wastewater. The height of the first fruit and average
weight of 100 seeds had not been influenced by factors tested.
