Evaluación Agronómica de dos Líneas promisorias de Arroz, en presencia de tres niveles de fertilización química y tres densidades de siembra, en condiciones de riego

In the grounds of the Farm Experimental "San Pablo" belonging to the Faculty of Agricultural Sciences, Technical University of Babahoyo, Province of Los Rios promising lines were seeded 'GO - 39815' and 'GO - 39,590' and variety 'S - FL - 09 'in the presence of plant densities 80, 100 and 120 kilograms of seed per hectare chemical fertilizer levels 60 - 40 - 70, 90 - 60 - 100 and 120 - 80 - 130 kg / ha of NPK , in order to: a) Select the genotype of higher grain yield, b) Identify the optimal densidad de siembra level of chemical fertilizer in order to maximize grain yield, and c) Economic analysis of grain yield in the cost function subtreatments production. Treatments were by genotypes and combinations subtreatments by planting densities and levels of chemical fertilization. Experimental design was used "split plot" in three replications. Correspond to the main plots and treatments as subplot experimental subtreatments. The experimental subplot area was 2 m x 5 m = 10 m2, while the useful area 1.5 m x 5.0 m = 7.5 m2 was, eliminated 0.25 m around the subplot........
