Effect of HMA strain and green manure on the growth of Coffea arabica L. seedlings grown in soil at the UBPC Narciso Camejo

Abstract

The present work was developed in the town of Guayacán, El Salvador municipality, Guantánamo province, with the objective of evaluating the AMF strain, green manures and soil-organic matter proportions for the production of quality Coffea arabica plants. The variables were evaluated: leaf area (cm2), fresh and dry mass of the plant (g), plant height (cm), stem diameter (mm) and root length (cm). For the statistical analysis, the STAGRAPHICS Version 5.1 statistical package in a Windows environment was used. The results obtained indicated that the Glomus cubensi strain was efficient for the production of coffee plants. The study also showed that the use of efficiently mycorrhizal Canavalia ensiformis, as green manure, is feasible and that production costs with the use of biofertilizers were reduced by $0.60, that’s why it is considered economically feasible.
