Fertilización química en el cultivo de arroz (Oriza sativaL.) en época seca en el cantón Naranjito.

This research conducted on the property of Luis Ortega, located in the Rcto. Anapoyo canton Naranjito, province of Guayas, whose location is: Latitude South 2, 17 and west longitude 70 °, 25, the duration of the investigation was 6 months in order to 1) analyze the agronomic performance of crop 4.15 rice foliar and soil fertilization under 2.) to analyze the benefit / cost of treatment in studies. To determine the research used 5 treatments and 4 repetitions with a design of randomized complete block (DCA), we studied the different chemical fertilization programs: 1.) Urea 300 Kg/ha-1 2.) 500 ml/ha-1 Green Humic + 500 ml/ha-1 Raizoot + 300 kg/ha-1 of Urea 3.) 300 Kg/ha-1 Urea + 50 kg/ha-1 DAP + 50 Kg/ha-1 of Muriate Potassium 4.) 500 ml/ha-1 Green Humic + 500 ml/ha-1 Raizoot + 300 Kg/ha-1 Urea + 500 gr/ha-1 Quantum 5.) 500 ml/ha-1 Green Humic + 500 ml/ha-1 of Raizoot + 300 kg/ha-1 Urea + 500 gr/ha-1 Quantum + 500 ml/ha-1 Biomax + 500 ml/ha-1 Green K. The agronomic variables studied were as plant height, number of tillers per m2, panicle length, panicle per square meter-day flowering of 1000 seeds weight, physiological maturity, yield, lodging, shattering, grain length. If differences were statistically significant. In the economic evaluation of treatment 500 ml/ha-1 Green Humic + 500 ml/ha-1 Raizoot, 300 kg/ha-1 of Urea + 500 gr/ha-1 Quantum + 500 ml/ha-1 Biomax, + 500 ml/ha-1 Green k reported a greater economic benefit of $ 1615.68, with a total cost of $ 876.48. In the economic evaluation T4 treatment 500 ml/ha-1 Green Humic, + 500 ml/ha-1 Raizoot + 300 kg/ha-1 of urea + 500 gr/ha-1 of Quantum, obtained greater benefit / cost of 2,891% and $ 289,1 better profitability.
