Morphological indices of okra seedlings produced with coffee grounds and eggshells

The okra has been highlighted for its nutritional potential and easy cultivation in small properties and in the so-called urban agriculture. Residues such as coffee grounds and eggshell have proved to be excellent alternatives for organic fertilization. Therefore, the objective of this work was to evaluate the agronomic potential of coffee grounds with eggshell in the production of Santa Cruz okra seedlings 47. The work was developed in the city of Chapadinha – MA, in a greenhouse, using a delineation completely randomized in a 4x3 factorial scheme for 21 days. Twelve treatments were used with 3 repetitions. The variables that gave significance between the factors, were explored by the Scott Knott test. Significance assessments described that there was no significant effect of the interaction between factors for any of the variables analyzed. However, there was a significant effect, alone, of the coffee grounds factor on the leaf area and the leaf area ratio. The higher the concentrations of coffee grounds, the lower results were obtained for the respective variables. Eggshell did not influence okra seedlings. It is necessary to carry out more research on the use of these residues in the production of vegetable seedlings.
