For the development of the investigation, a randomized complete block design (DBCA) was used with thirteen treatments and three repetitions to ensure the effectiveness of the investigation. The treatments resulted from different doses of mineral and organic fertilizer and their combinations, thus having 50 kg/ha, 100 kg/ha, 150 kg/ha, 200 kg/ha. The control doses in the land where the investigation was carried out, a total fertilizer was applied, except for the element under study, the doses of the mineral fertilizer were the following: 50 kg/ha, 100 kg/ha, 150 kg/ha, 200 kg/ha and the combined doses 25 kg + 25 kg, 50 kg + 50 kg, 100 kg + 100 kg, 75 kg + 75 kg with a control treatment. Regarding the results of the agronomic variables, the application of organic and mineral nitrogenous sources and doses expressed a varied response on plant height, statistically different from the control, being the combination of 50+50 the one that expresses the highest results, therefore which is attributed to the synergism between the two sources. By not observing significant differences between the treatments in terms of plant morphology, it can be seen that these variables are defined by the hybrid used in this investigation (Thunder). The best treatment in terms of performance was the mineral treatment with a dose of 50kg/ha, being the same as when evaluated to know the benefit obtained for each dollar invested, it proved to be the one that obtained the greatest profit. Thus demonstrating that fertilizing with mineral fertilizer and adequate doses the crop responds effectively. Regarding agronomic efficiency, the combination of fertilizers with doses of 25kg/ha+25kg/ha is the one that obtained the best results. |
