research was conduted out in the Technological Institute of

Agriculture of Oaxaca. N. 23 located at the Ex Hacienda de

Nazareno, Xoxocotlan, Oaxaca, in order to evaluate the

effect of three planting densities on the vegetative

development and production of different tomato hybrids

with growth habit, cultivated in greenhouse. The tomato

hybrids were SXT, DRW3410 and SXT0289. The results

show that it wasn.t a statistic difference for the hybrids,

only for the planting densities, of 5.3 plants/m2 and 4

plants/m2 with 17.52 y 17.37 kg/m2, respectively; wich

represents a yield average of 151.6 t/ha.
