The objective of this project was to find the impact of using different yield densities on chlorophyll concentration in the vegetative stage, cob height and four performance components as Prolificacy, number of corn kernels per row, the rows number and weight of these corn kernels, of the hybrid corn “Impact in the town of Valley off San Juan (Tolima)”.
The researching to develop a test with a completely randomized design in sub-divided plot with four replicates blocks, at the main estate is established treatments row spacing (0.7 m and 0.8 m) and the sub-estate the treatments number of plants per lineal meter (7, 8 and 9).
Results show that the content of chlorophyll, cob height, number of rows, the 1000 corn kernels weight and performance not affected at significant level (0.05) by high population densities were obtained, while the number of kernels per row is affected by the action of row spacing to significant level. Treatment with higher performance (11690.97 kg / ha ± 1303) and profitability (59.65%) was achieved with a density of 112500 plants per hectare.
