Resumen:
The residual effect of previous fertilization on subsequent crops is of the utmost importance, since fertilizing the soil in such intense activity as the olericulture would increase the cost of production whenever a new crop is implanted. This work was carried out in the experimental farm Rafael Fernandes, Department of Plant Sciences, Federal Rural Semi-Arid University (UFERSA), Mossoró-RN, from January to February 2016, with the objective of evaluating coriander grown in organic system under the residual effect of organic fertilization. The experimental design was a randomized complete block design with treatments arranged in a 4 x 4 factorial scheme, with three replications. The first factor was the bovine manure (0.0, 3.0, 4.5 and 6.0 kg/m2), the second by the soil incorporation periods (28, 49, 64 and 84 days before sowing - DAS). The planted coriander cultivar was Verdão. The evaluated characteristics were: height and number of stems per plant, productivity, number of sauces and dry mass of coriander. There was no interaction between the characteristics evaluated for the coriander culture. The dose of 6.0 kg/m2 at 28 days of incorporation was what prompted the greatest residual effect in the evaluated characteristics. Bovine manure was efficient in promoting residual effect in coriander cultivation.
