Abstract
An Integrated Production System consists of exploring land for the production of food and other high-quality products through the use of natural resources and regulatory mechanisms to minimize the use of polluting inputs, thus ensuring sustainability.
The aim of this study was to evaluate the production of Carolla rose, grown under different soil management systems in Integrated Production System. Carolla rose graftings were grown in soil in a greenhouse.
The experimental design was randomized complete block in split plot arrangement in space, with eight treatments and four replicates.
The treatments consisted of four percentages (25, 50, 75 and 100%) of chemical fertilizer, based on recommended rose fertilization for the state of Minas Gerais, Brazil, versus presence and absence of green manure (Calopogonium mucunoides) grown intercropped with the rosebush.
Treatments that did not receive 100% of chemical fertilizer have been incremented with two types of bio-fertilizers monthly applied: Bokashi (16 g/plant in the soil) and Supermagro (5% in foliar application). The assessments were conducted three times a week during one year.
The crop management was carried out in accordance with the rules of integrated production.
It was observed that in the presence of green manure, the number of stems produced per plant (7.16), leaf dry weight (4.55 g) and total dry weight (12.06 g) were lower when compared with plants grown without green manure (7.98, 5.01 and 12.90 g, respectively). For the other parameters evaluated (stem length and flower bud length, stem base diameter and flower bud diameter, stem and flower bud dry weight), no significant differences were observed.
In the first year of evaluation, it was found that it is possible to produce high-quality roses using smaller percentages of mineral fertilizers, since the production and quality of plants were similar even with reduced fertilization.
