Carnauba straw incorporated into the soil for fertilization carrot in organic cultivation
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 0, Issue 0
Abstract
Carrot is one of the most produced vegetables in Brazil and, with the growing demand for organic vegetables, it is necessary to develop production technologies that are less dependent on external inputs and more accessible to family agriculture. The objective of this study was to evaluate the effect of the addition to soil of carnauba straw as fertilizer, incorporated under different pre-planting periods, for the organic cultivation of the carrot. The experiment was carried out in the Experimental Horta of the Instituto Federal do Rio Grande do Norte, Campus Ipanguaçu, using the experimental design in randomized blocks with three replicates and five treatments referring to the times of 15; 30; 45 and 60 days for the incorporation of carnauba straw, in the amount of 14 t ha-1 , prior to planting the carrot, and a control treatment without addition of straw to the soil. The evaluated characteristics was dry mass of the aerial part, the length and root diameter, and productivity. There was an effect of the incorporation time of the carnauba straw on the length and productivity, being the highest values observed when the straw was incorporated between 15 and 30 days before sowing.
