Diferentes niveles de fertilización química en el cultivo y producción del hibrido de maíz (Zea mays) P30K73

The purpose of this study was to evaluate different levels of chemical fertilization in the cultivation and production of hybrid corn (Zea mays) P30K73. It was held in the Villa San Carlos, located in Canton Province of Guayas Balzar, at the geographic coordinates of west longitude and latitude 79.85275 1.30804 south, at an altitude of 36 meters; field research lasted 120 days. The treatments used were T1 P30K73 + 750 kg / ha of C1, T2 P30K73 + 625 kg / ha of C2, T3 P30K73 + 500 kg / ha of C3, and T4 Control (135 kg Urea + 45 kg muriate / ha, design arranged in a randomized complete block (RCBD) with 4 replications, to determine the statistical difference between treatment means Tuckey test was used at 0.05%. Plant height of 281.25 cm, height of insertion of ear with 125.93 cm, perimeter stem protrudes 7.98 cm treatment T1 K73 P30 +750 kg / ha of C1. Treatment T2 + P30 K73 625 kg / ha of C2 at 53 days after sowing the male presents is the earliest flowering. Treatment T1 K73 P30 +750 kg / ha of C1, to 58.25 days after planting presents silking is the earliest. Treatment T2 + P30 K73 625 kg / ha with a value of C2 was 50.78 g giving greater weight percent grains provided, with a yield of 7465.00 kilos per hectare was higher performance. The highest value with $ 2,010.45 USD is the production cost of treatment T1 in which 750 kg / ha-1 was applied C1ha. The most useful $ $ 687.57, T2 have the treatment was applied to 625 kg / ha of C2 ha-1. The biggest benefit / cost ratio 1.36, presents the treatment T2, which cultivated the hybrid P30 K73 + 625 kg / ha of C2 ha-1.
