Resumo
Chives are one of the most popular spice plants in world cuisine. It is usually produced by small producers, often in an organic farming system. However, research with chives in this production system is lacking. The purpose of this study was to evaluate the production of chives with the use of organic fertilizers before planting and in top dressing. Seven treatments were evaluated, resulting from the factorial 2x3+1, with two organic fertilizers (castor bean cake and hoof and horn powder) x 3 application modes (100% before planting; 100% in top dressing; 50% before planting and 50% in top dressing) + 1 control (without these organic fertilizers). The experimental design was in randomized blocks, with five replications and plots of 1 m2. The relative index of chlorophyll (“Spad” index), height, number of leaves, fresh and dry weight of the plants were evaluated. All treatments of the factorial were better than the control, showing that these organic fertilizers improve production in chives. It is recommended to use the hoof and horn powder in installments (50% before planting and 50% in top dressing) or 100% in top dressing, the latter option being more interesting for reducing the need for labor, with just one application moment.
