    Evaluación del rendimiento y calidad del tomate riñon (Lycopersicum esculentum. mill) a la aplicación de policrilaminicos polimericos orgánicos Puembo, Pichincha, Ecuador

    The cultivation of tomato kidney is one of the most cultivated vegetables in the world for its nutritional content and for its demand in the daily diet, for that which is necessary to look for new technologies through an organic process as they are the polymers that it is a product floculante-aglomerante, corrector and amendment of chemical action, physics and biological for the agricultural floors. This investigation was carried out in the Province of Pichincha, Parish of Puembo located 2400 mls For this investigation work an experimental design of complete blocks was used at random, in factorial arrangement 4 x 3 + an absolute control with 3 repetitions. The factor A: it corresponded to three polymers A1: Agrocontrol forte, A2: Biosorb, A3: Nitrozym and A4: previous combination of the 3. The factor B: they were times of application of polymers, B1: Third week after the transplante, B2: Eighth week after the transplante, B3: Third and eighth week after the transplante. Was carried out a chemical analysis of the fruit in total solids, pH and grades Brix, in the laboratory of the Central University of the Ecuador. Analysis of Variance was made, Test of Tukey to 5% for main factors, contrast ortogonales for main factors and witness, Analysis of Correlation and Regression, Economic Analysis of Budget Partially and Marginal Rate of Return (TMR%). The most outstanding results obtained in this investigation were: For the seed planting of hybrid tomato Lummi (F1) low hothouse in the area agroecológica of Puembo, the application of the polymer Agrocontrol forte is recommended in a proportion of: 100 liters of water, 100 grams of agrocontrol and 0,15 liters of humus bonus, with two applications in dench form to the base of the plant this should be carried out to the third and eighth week after the transplante, to improve the productivity of the cultivation. The components of the yield (independent Variables) that contributed to increase the yield they were: yield for parcel and percentage of fruits of first category. The best net profit based on the economic analysis of budget partially, in function only of the costs that vary in each treatment was the T3: A1B3 (Agrocontrol third and eighth week after the transplante) with $10.928/Ha. The highest value in the TMR, was calculated in the treatment T3: A1B3 (Agrocontrol third and eighth week after the transplante) with a value of the TMR of 52,63%. Finally this investigation demonstrated that it can improve the cultivations of tomato low hothouse local with the implementation of the polymer Agrocoltrol without losing the quality of the fruit, being able to guide to an ecological production, and healthy product for the consumers
