Raised the following objectives.) Evaluate the production of six hard corn hybrids with two formulations of chemical fertilizers in the area of Balzar, Guayas Province, b). Identify the most productive hybrid under the influence of chemical fertilizers, c). Establish the profitability of the treatments. The factors used in this research are: Factor A corn hybrids: Hybrid Pioneer 30F87. Pioneer Hybrid 3041, Pioneer Hybrid 30K73, Pioneer Hybrid 30K75, 30F35 Pioneer Hybrid, Hybrid Senac 810, Factor B Chemical Fertilizers Urea Fertilizer. Full fertilizer dose kg/ha-1 460 (460 kg/ha-1 Yaramila. Dose The experimental measurements performed on maize hybrids in the project evaluated a total of 50 plants per experimental unit, hybrids harvested 140 days and the experimental measurements. Germination percentage (%). Plant height. Height (cm). Load height (ear position). Flowering time to 10 and 100%. Yield per plant (g). 1000 seeds weight (g). Wet at harvest (%). Yield per plot (kg). Gopher length (cm). Diameter of the mole. Number of rows per ear. Mole percentage ratio grain. Yield per ha-1. Evaluation of major diseases. Rusts. Helminthosporium turcicum. Stunting. Stem diseases. Diseases of the ear. Kg/ha-1 performance. Economic analysis Fertilization in maize with fertilizer Yaramila was the most favorable variables, compared with Ureas fertilization. In the six corn hybrids that yield performance presented The Pioneer Hybrid 30F35, germination percentage was 96.83%, 237.95 cm plant height, loading height (ear position) 151.66 cm, time of flowering to 10% 54.00 and 100% 60.00 days, 254.36 yield per plant, 1000 grain weight of 440.00 and 348.57 g, 30.33% wet, yield per plot 8.22 kg, length 10.33 cm gopher, gopher diameter of 3.30, number of rows per ear 18.00, percentage ratio grain / 4.39 mole, yield per ha-1 wet and dry 8075.00 6525.33 kg/ha-1. In the evaluation of diseases of maize rust, Helminthosporium, turcicum stunt, stem diseases, diseases of the ear, present range of 1 to 3 ratio of low to moderate presence of diseases, treatments in the T12 study was that best cost / benefit ratio presented with 1.86 |
