  • Descrição: The objective of this study was to evaluate the effect of plant spacing and water supplementation on growth and productivity of physic nut (Jatropha). This research was carried out at the experimental area of the Instituto Federal Goiano--Rio Verde during the period 12/09/2009 to 30/04/2011, in a randomized block design with three replications. The factors consisted of seven plant spacings and two water conditions, each plot consisted of 16 plants, and four central plants were considered for data collection. At 60 days after transplanting of seedlings, fortnightly the evaluation of the parameters plant height, number of branches, leaf area and productivity was carried out. The plant spacing showed no significant difference for height, branching and productivity, while the water supplementation had significant effect on height at 240 days after transplanting. Seed production under rainfed conditions was higher in 3 x 3 m spacing and with complementary water in 4 x 4 m spacing.
