Respuesta del cultivo de arroz (Oryza sativa L.) bajo riego, a la aplicación de fertilizantes edáficos biológicos, complementarios a la fertilización química

VIII. SUMMARY This work was done on the grounds of the Experimental Farm "San Pablo" of the Faculty of Agricultural Sciences at the Technical University of Babahoyo, located at km. 7.5 of Babahoyo Montalvo route with geographical coordinates of 79 ° 32 ', west longitude and south latitude 49' 1. This area has a humid tropical climate with an average annual temperature of 25.80 C, an annual rainfall of 2203.8 mm, 79.6% relative humidity, evaporation of 1738.7 mm and a height of 8 m.s.n.m. The floor is flat topography, clay loam texture and regulate drainage. certified seed of the rice variety INIAP 16, whose research objectives were to study the behavior of rice to the application of the treatments used; bilógico fertilizer and establish the appropriate dose effect on performance and cost analysis evaluated based treatments yields. Soil treatments biological fertilizers, complementary chemical fertilizers, such as GreenEdge were evaluated; Dix 10N and Naturcomplet - G in doses of 25 and 50 kg / ha plus two additional treatments of chemical fertilizer according to soil test results and by farmers. the experimental randomized complete design with eight treatments and three repetitions blocks used, comparisons of means were performed using the Tukey test at 95% probability. The experimental plots had dimensions of 3 x 6 m. The separation between replicates was 1 m, giving an area of 528 m2 assay. All agricultural work required in the cultivation of irrigated rice for normal development were made, and these soil analysis, soil preparation, planting, watering, fertilizing, weed control, plant protection and harvesting. straw weight - to estimate correctly the effects of treatments data plant height at harvest, days to flowering and maturity, number of tillers and panicles per square meter, length and grains per panicle, grain ratio were taken 1000 grain crop yield and economic analysis. According to the results, it was determined that the cultivation of rice (Oryza sativa L.) under irrigation, got excellent response to the application of biological soil fertilizer, chemical fertilization complementary; the tallest plants at harvest time and increased number of tillers / m2 was presented with the application of Dix 10 N (25 kg / ha) + N - P - K, while applying chemical fertilization based on N, P, K by farmers, cultivation flourished in most time; all rice plantation matured to 102 days; employing GreenEdge (in doses of 50 kg / ha) + N - P - K showed greater number of panicles; the average values of panicle length and grains per panicle excelled by applying Naturcomplet - G (in doses of 50 kg / ha) + N - P - K and using Naturcomplet - G (in doses of 25 kg / ha) + N - P - straw, 1000 grain weight and higher yield (4329.0 kg / ha) and net profit ($ 165.75) - K larger grain ratio was obtained.
