Efecto de la fertilización química en base a los resultados del análisis de suelo en la variedad Iniap 15 y dos líneas promisorias de arroz, en la zona de Babahoyo

The present investigation work was carried out in the Ability of Agricultural Sciences of the Technical University of Babahoyo, located in the Km 7 ½ of the road Babahoyo - Montalvo whose outlined objectives were: to evaluate the effect of the chemical fertilization based on the floor analysis in the cultivation of rice; to identify the genotype of more yield and to analyze the treatments economically. Three treatments were used (genetic material), as Iniap 15, Lines GO 37647, GO 39845 four subtratamientos (fertilization levels), with the help of nitrogen (urea), potassium (muriato of potassium) and Zinc (Zinquell), with four repetitions. The design divided Parcels was used, with three treatments, four subtratamientos and four repetitions. For the comparison of the averages of the variables, the test of Multiple Ranges was used from Duncan to 5% of probability. For the development of the investigation the following works were made, as floor analysis, floor preparation, siembra, control of overgrowths, watering, fertilization, control fitosanitario and it harvests. To estimate the effects of the treatments and subtratamientos they took the following data, as plant Height to the crop, macollos/m2 number, panículas/m2 number, days to the floración, days to maturation, longitude of the panícula, grains for panícula, weight of 1000 grains, yield, quality molinera and economic analysis.
