When planted at a distance of 0.35 x 0.35 m, with two plants per site corresponding to the research (T2) compared with the TA planted at a distance of 0.25 x 0.25 m, and eight plants per site, there is a numerical difference, in which the T2 exceeds the TA by approximately 19%. The T2 treatment (research), had a profitability of 97% on production costs and 49% in sales income in relation to the control (TA) which obtained a profitability of 45% on production costs and 31% in sales income.
