Effect of the fertilization on the nutrition and yield of the red pepper (Capsicum spp.) in the Valley of the Cauca, Colombia.
This study was realised with the purpose of to evaluate the effect of the chemical, organic fertilization and biofertilization on the nutrition and yield of the red pepper (Capsicum spp.) in the Valley of the Cauca in the initial production of plants in breeding ground and final production in field. Two experiments were realized, one in stage of fish-pond and other one in field stage. In fish-pond an experiment was realized where there was evaluated the effect of the different types of fertilization in chili and other one where there was evaluated the effect of the chemical, organic fertilization and biofertilización in chili. In field there was evaluated the effect of the chemical, organic fertilization and biofertilización in chili. The physiological evaluated variables were: fresh weight root and air, number of leaves (sheets), height of the plant(floor) (in cm), diameter of the stem (in mm), dry total weight, dry weight of root and air. In the experiment of biofertilización both for stage of fish-pond and for the field stage, there were evaluated six treatments and a statistical design of complete blocks at random, this way: Fertilization of complete synthesis (Witness), fertilization of synthesis completes more organic, integrated fertilization of synthesis completes, organic and biofertilización 1 (solubilizador of phosphorus: with base in Penicillium janthinellum (1x107conidias/ml), Fertilization of synthesis completes more organic more mycorrhizae, integrated fertilization of synthesis completes, organic and biofertilización 2 (Fastener of Nitrogen: with base in Azotobacter chroococcum (1x108 UFC/mL) and Azospirillun sp. (1x108 UFC/ mL), integrated fertilization of synthesis completes, organic and biofertilización 3 (fastener of nitrogen: with base in Azotobacter chroococcum (1x108 UFC/mL). The beginning of the experiment classifified like Typic Hapludolls. The statistic analysis threw that in all the experiments the denominated treatment fertilization of organic + chemical synthesis + mycorrhizae was the one that I throw the best results followed of the treatments to which the biofertilization source was applied to them (Microorganismos solubilizers of phosphorus and nitrogen fixing devices). One concluded that the greater red pepper yield is obtained when a complete chemical source plus a source of organic matter is applied to the soil more mycorrhizae arbusculares, for studied soils. In addition that the biofertilization is a complement of the chemical fertilization.
