Effect of Phosphorus 200 CH on Lactuca sativa L., Fomento 95 cultivar in organoponics (Original)

Abstract

With the objective of evaluating the effect exerted by the application of Phosphorus at 200 CH in Lactuca sativa L., Cultivar Fomento 95, cultivated in organoponic conditions, the research was carried out with a randomized design, in the Ñico López cultivation area, in Bayamo municipality, Granma province. Two hundred lettuce seeds were used: 100 were placed in a Petri dish and imbibed with 10 mL of the homeopathic product and 100 in another Petri dish with 10 mL of distilled water for 30 min; then, both groups were sown. At 23 days after germination, 20 seedlings were transplanted into a bed: 10 from the experimental group and 10 from the control group. Three days later, the plants of the experimental group were sprayed, using a preparation of 10 mL of the homeopathic product in one liter of distilled water. This procedure was repeated three weeks later, on the same day, always on the foliar part at 8:00 am. Measurements were made of the variables: germination percentage and leaf number, length and width, 30 days after transplanting. Both treatments were statistically compared by the t student test in all the variables evaluated. The homeopathic product increased the germination percentage and stimulated the growth and development of the variables under study.
