Study of Chemical and Organic fertilization and its effect on the cultivation of Corn (Zea mays.), in the commune. Rev. Inv. Cs. Agro. y Vet.

Based on the management of various types of fertilizers of organic origin such as chemical used in the cultivation of Corn (Zea Mays), it was proposed to determine the differences given in the morphological development of the crop; and to identify the best nutrition that allows obtaining higher levels of productivity and which in turn will establish the cost-benefit relationship of the established treatments. The applied methodology allowed the use of a completely randomized block model of four repetitions, the treatments based on fertilization were based on: Yara, Ecological, Organic, Chemical and a control treatment to which no fertilizer was applied; the variables considered within the evaluation process were: plant height, stem diameter, leaf length, ear insertion, ear weight, cob weight, 100 grain weight, grain weight, number of rows, row arrangement and ear damage. The results showed that the Yara treatment reached a higher productivity thus obtaining 38.31 kg in the weight of the plot and that in turn allowed to show a better morphological development in all its stage; establishing a plant height of 213.78 cm; a plant diameter of 72 mm and a blade length of 101.58 cm; which allows for a greater photosynthetic capacity thanks to its greater foliar coverage.
