Determine phenological periods of pineapple plants cv. MD2, under the ecological conditions of the area of Machala.2. Establish meteorological, phenological and nutritional treatments with different correlations.To this end was used: Land , knapsack , computer, printer , tools (shovels, lampillas , machetes ) , fungicides , pesticides, fertilizers , camera , tape measure, data record, ballpoint pen , magnifying glass, irrigation pump , labels , painting, office material , calculator , signs and pineapple plants didactic orchard tropical species , Faculty of Agricultural Sciences , batch is aged three months after planting , MD2.To study the effect of plant phenological pineapple (Ananas comosus L.) by application of five formulations of mineral fertilizers NPK mase and micro elements; F1 184-00-00 - 1.5 miro elements; F2. . 00-00-156-2.0 microelements 198 F3 - F4 92-0. 198-92 - F5 00-1.0 and absolute control. Treatments Hijuelos planted with selected base of plants arranged in a field Block Design with four replications randomly assigned. The variables studied were plant height at start of treatment, rosette diameter, days to the issuance of leaves, length and width of leaves every 15 days. Days to the issuance of inflorescence, inflorescence size, number and location cuttings, fruit size at the end of the trial record climatic parameters : temperature humidity and precipitation , and soluble solids.Statistical analyzes with different agronomic characteristics MD2 variety yielded interesting information the same as a probabilistic prediction model that generated adjusted index also highly significant determination R2. The environmental conditions prevailing in the study area together with soil requirements as regards fertility were satisfactory, but not the pH varied from neutral to slightly alkaline. The phenological stages of vegetative growth in plant height, leaf size, leaf emission, showed that the linear statistical models were coupled to field readings generating predictive models of crop growth in general. The MD2 variety was not susceptible to the incidence of pests such as weevils, scales, mealy bugs and leaf or root diseases. In correspondence with the climate and natural soil fertility trial , the fruit pulp contained between 11 and 12.8% soluble solids or pulp Brix development structure for asexual vegetative propagation of the variety was low at null the analysis and development of linear prediction models with the data generated in the study of agronomic traits , is a good database for future comparisons in other trials in the MD2 variety Corresponding to the climate and the natural fertility of the land assay , the fruit pulp contained 11 to 12.8% soluble solids or pulp Brix . |
