A unifactorial completely randomized block design (DBCA) with 5 repetitions was used. For the statistical analysis, the coefficient of variation was determined for all variables and expressed as a percentage; in addition, Tukey's test of means was used at 0.05% error probability, showing significant differences in the variables, number of fruits per plant, thickness of rind and diameter of fruits; which shows that there was significant influence of the treatments and that it was T3 that obtained the best results. With respect to the other variables under study, these did not present significant differences between the control and the other treatments. It is concluded that the best method for the productive optimization of this crop is the one corresponding to T3 (artificial pollination and unprotected pistil), which presented the highest results in the variables mentioned above, compared with the control and other treatments. |
