Resumen
This investigation aimed to evaluate the grafting of tomato (Solanum lycopersicum Mill) on cape
gooseberry (Physalis peruviana L) rootstocks, with three doses of salinity in Chimborazo
Province. A bifactorial, completely randomized block design (CRBD) was used in divided
plots, with nine treatments and three replications. The treatments corresponded to two cultivars
of wild cape gooseberry (B1) and commercial cape gooseberry (B2), used as rootstocks with a
control (B3), (ungrafted tomato), with three doses of salinity: low (A1), medium (A2), high
(A3).In this investigation, height and number of leaves of the graft were evaluated at thirty and
sixty days, which was the life time of the grafts, then the investigation was based on a
completely randomized block design (CRBD) monofactorial using the salinity factor for the
study where parameters such as number of fruits per bunch, fruit weight, fruit equatorial
diameter, fruit peel weight, fruit pH, percentage of soluble solids, yield in kg/plant, kg/ha were
evaluated; kg/ha and the economic analysis was carried out using the benefit-cost ratio per
treatment. The capegooseberry rootstocks did not respond to tomato grafting; for the salinity
section, the number of fruits per bunch was seven; fruit weight 135.17g; fruit diameter 6.38cm;
peel weight 117.93g; brix degrees 5.90 and 1.72 kg/plant. It was concluded that the best yield
was obtained with thelow treatment (0-3) mmhos/cm, with an average of 46 MT/ha and a
benefit-cost ratio of 3.17 dollars. It is recommended to work with other types of rootstocks with
the same botanical characteristics and to use low doses of salinity.
