Efecto de la interacción entre densidades poblacionales en el rendimiento de grano del cultivo de Sorgo.

This research was established in the grounds of the farm " San Pablo " property of the Faculty of Agricultural Sciences , Technical University of Babahoyo , located at Km 7.5 of the satellite Babahoyo - Montalvo, hybrid sorghum in the ` P83G19' con to: a ) Determine the proper planting distance to maximize grain yield , b ) Identify the level of chemical fertilizer to achieve significant increases in grain yield , c ) evaluate the effect of interactions planting distances and levels of fertilization , and d ) Analyze economically grain yield considering the cost of production. Treatments were constituted by planting distances 0.45 m 0.50 m between rows , and subtreatments by chemical fertilization levels : 0-0-0 , 60-30-50 , 120-50-100 , 180-70-150 and 240-90-200 kg / ha of NPK . Experimental design "split plots" was used in four replications. The main plots corresponded to treatment and the subplot experimental subtratamientos. The experimental subplot consisted of 6 rows of 6 m length spaced at 0.45 m and 0.50 m , giving an area 16.2 m² and 18 m² , in that order. The useful area of the experimental subplot was determined by the two central rows, ruling a line on each side edge effect .............
