Agronomic response of corn to the application of mycorrhizae in a reddish-brown phersialytic soil (Original)
Keywords:
Zea mays; maize; mycorrhizae; agronomic responseAbstract
The research was carried out at the Jiguaní Municipal University Center of the University of Granma. The objective of the article is to evaluate the agronomic response of corn (Zea mays L.) to the application of different doses of arbuscular mycorrhiza in a reddish-brown fersialitic soil. A randomized block design consisting of five treatments and three replicates was used for the experimental set-up. Statistical analyses were carried out with the Statistic program for Windows, applying an analysis of variance. The variables number of ear/plant, number of rows/ear and number of grains/row were evaluated. The results showed that the highest efficiency of arbuscular mycorrhizal fungi was in treatment number 5 (20 grams per nest), demonstrating a favorable behavior in the indicators evaluated, guaranteeing increases in the number of ear per plant, number of rows per ear and number of grains per row, without the need to apply inorganic fertilizers. With the inoculation of mycorrhizae in maize, a better nutritional status of the plant can be appreciated.
