Compost and MPA were applied 30 days before the transplant, the Steiner solution from the transplant and the microorganisms every eight days up to harvest in drip irrigation; the population density was 25,000 plants per hectare, the which they were handled to a stem in separate rows 1.6 meters between they. The experimental design was randomized complete block with four replications and nine treatments. The 25 Mg•ha −1 of compost and 6 Mg•ha −1 of MPA (T8) were sufficient to yield 114.0 Mg•ha −1 with an increase of 9.3% compared to 104.3 Mg•ha −1 achieved with Steiner solution. Compost, MPA and M were made that the soil increased the fertility from before transplantation, and until the harvest is continued providing enough nutrients, with the exception to Cl and S, which were not detected after harvest. Deficiencies of Cl and S perhaps were one of the causes of that plants did not produced beyond that achieved with Steiner solution or T 8 , this latter that in turn allowed manage more sustainably the soil and plants that with Steiner solution, while with T 8 was supplied organic matter and assimilable mineral by plants.

La investigación se realizó con el objetivo de conocer la influencia de la densidad de plantas y poda de tallos sobre el crecimiento de planta y rendimiento de frutos de pepino cultivado bajo condiciones de invernadero. Se usó el diseño de bloques completos al azar en arreglo factorial, con dos niveles cada factor: densidad de plantas (1.68 y 2.22 plantas/m2) y poda de tallos (uno y dos tallos/planta). Los tratamientos: T1) 1.68 plantas/m2 con poda a un tallo/planta, T2) 1.68 plantas/m2 con poda a dos tallos/planta, T3) 2.22 plantas/m2 con poda a un tallo/planta y T4) 2.22 plantas/m2 con poda a dos tallos/planta, se establecieron con cuatro repeticiones. Los resultados indicaron que la biomasa fresca de tallo/planta y seca de hojas/planta disminuyó al aumentar la densidad de plantas, pero aumentó en las plantas con poda a dos tallos/planta. La l...
