    Inducción de floración y cosecha en la guayaba (Psidium guajava), mediante la aplicación de nitrato de potasio (KNO3)
    (2019-03) Caiza Chicaiza, Roberto Carlos; Yánez, Wilfrido
    The work was realized in the property of Mr Carlos Caiza, placed in Tungurahua's province, canton Pelileo, Community The Clementina, These are located 2124 msnm, and whose geographical coordinates it is a south latitude 1º17 ' 25.5" S, and of length west 78º31 ' 07.3" 3W, with the aim of: to evaluate the application to foliate of three concentrations of nitrate of potassium (KNO3) 3, 6 and 9 %, to advance the induction of floral yolks in culture established of guava. The treatments were three more an absolute witness. I use the design of blocks completely at random, in arrangement factorial of 2 x 2 + 1, with three repetitions. The analysis of variance was effected, DMS's tests to 5 % and Tukey's tests to 5 %. The economic analysis was effected by the methodology of the RBC. The application to foliate of nitrate of potassium (KNO3) with a concentration 3 %, produced the best results, being managed to diminish notably the days for the appearance of the first floral yolks (9,88 days after the third application); major, uniformity of flowers, better quality of fruits for plant and better performance (31,57t/ha). With the application of nitrate of potassium (KNO3) to 6 %, also good results obtained, but with a minor effect that the concentration of 3 %. With this treatment I observe the floral yolks (12,85 days later to the third application), with a uniformity of flowering, and fructification and good performance of (29,55t/ha). Of economic analysis one concludes that, the treatment two (KNO3 to 3 % of concentration), I reach the major relation I benefit cost of 1, 37 sometimes invested.
