Repuesta del híbrido de maíz (Zea mayz L.) DK7088 a varios niveles de fuente d fertilización en la zona de Mocache.

This research was conducted at the Experimental Farm "La Maria" of UTEQ, located at kilometer 7.5 of the Milky Quevedo-The Joint, Los Rios Province, whose geographical location is 1 ° 3 '18 "latitude South and 79 ° 25 '24'' West longitude, at an altitude of 120 meters above sea level. The investigation lasted 120 days, between the months of January to May 2011. The main objective is established "Evaluate fertilization levels and sources for hybrid (corn) DK 7088 Mocache area" also raised specific objectives 1) To determine the effect nieveles and fertilizer sources for corn DK Area 7088 Mocache y2) Perform economic analysis of treatments. This raised unDiseño randomized complete seven treatments with three replications, in addition, comparisons were made orthogonal. As study variables were raised height at harvest height inserting ear, plant height at 30 days, number of harvested plants, perimeter cob, cob uniformity, moisture content (%), grain weight gopher, gopher grain weight without, yield per hectare of crop moisture, yield per hectare adjusted to 13% moisture, disease incidences (red tape, Curvularia, and Fisoderun Helminthus) and economic analysis. Concluding, 1) plant height at harvest the best result was obtained with treatment 2 (180 kg + 300 kg EQ2 AMIDES + 30 kg of organic matter "AGASOIL"), also in the insertion height ear and plant height at 30 days was highlighted treatment 4 (200 kg + 200 kg EQ2 Agrofeed + 50 kg + 100 kg AMIDES Nitromag + 20 kg of organic matter "AGASOIL. 2) The number Harvested plants were obtained 49.19 average plants, also in the perimeter of the ear was observed average of 16.27 cm and the uniformity of treatment cob by averaging 3.79 was obtained in scale established. 3) The grain moisture at harvest was observed average of 27.65%, and the grain weight was observed tuza more than 2.16 g average allowing difference calculated by weight of the grain without gopher. 4) in addition to the per hectare yield adjusted to 13% moisture was observed on average 8653.38 kg ha-1. 5) The treatment 0 (control) and 2 (180 Kg of EQ2 + 300 Kg of amides + 30 kg of organic matter (AGASOIL) had the lowest incidence of red ribbon, and was obtained in the incidence of Curvularia only treatment 1 (200 kg EQ2 + 300 Kg of AMIDES + 30 kg of organic matter "AGASOIL") obtained the lowest level. was also observed low levels of Helminthosporium and Fisoderma. 6) Treatments 4 (200 kg EQ2 + 200 Kg of Agrofeed + amide 50 kg + 100 kg + 20 kg Nitromag Organic Matter "AGASOIL") and 0 (control) achieved the highest returns.
