Incidencia de la luz artificial en la productividad del cultivo de phlox (Phlox paniculata) variedad CEO. En la finca la Tolita de grupo Esmeralda Ecuador, parroquia Guayllabamba, provincia de Pichincha

Abstract

The tradition of the culture of flowers is original of Holland where it begins to specially appreciate his ornamental value at the time of the dark by his four stations becoming a product of great demand for the decoration of his homes. In Ecuador the florícola industry has been developed with an accelerated growth being the zones of greater growth the provinces of Pichincha, Cotopaxi, Azuay, Imbabura, Chimborazo, arriving to reach an area cultivated around the 2976 hectares This investigation was made in the locality, of the Property the Tolita, parish of Guayllabamba province of Pichincha that is to an altitude of 2,250 mnsm. This test with its parcel already established beginning in March of the 2009 with the exposition of the following specific objectives:  To determine the best time of exhibition and frequency of artificial illumination in the productivity of the ceo culture of phlox variety.  To evaluate the effect of the incandescent light on the growth and the productivity of the ceo culture of phlox variety.  To make an economic analysis of the best treatment and their relation Benefit/Costo (RB/C). A design of complete blocks with four repetitions was used at random, 3 times of illumination by 3 weeks of exhibition that constituted the 9 treatments. Variance analyses were made, tests of Tukey to 5%, analysis of main effect between factors, analysis of correlation and simple regression The most excellent results were the following ones: The agronómica answer to the artificial light of the 9 treatments was very different, having like better result to the T6 treatment: A2B3 (12 hours of continuous illumination) (weeks of exhibition 8-11) with greater yield, better degrees of quality in the boncheo, greater length of stem, minor percentage of stems not induced, in addition diminished the days to the harvest, as far as thickness of stems and plagues and diseases did not have significant differences. As far as the relation benefit cost (RB/C), the treatment that greater benefit obtained was the T6, in spite of its high consumption of electrical energy this was compensated in yield of stems, better degrees quality in the boncheo, minor cycle, minor percentage of stems noninduced and greater length of stems, reason why I diminish the cost stem and it did to him that he is but the profitable one. Finally this investigation I contribute to improve the productivity and yield of the culture of phlox, since it had serious problems as far as production and it was managed to determine the necessary amount of artificial light that ceo variety for its optimal development needs phlox.
