Production of seeds and seedlings in the no-tillage system of vegetables: a systematic review

Abstract

Direct Planting is a process of sowing in a non-turbulent soil, in which the seed or seedling is placed in furrows or pits, wide and deep enough to obtain an adequate coverage and a good contact of the seed with the soil. Breaking this dependence, there will be the fixation of the farmer in the field, through the reduction of production costs, improvement of the physical, chemical and biological conditions of the soil, greater sustainability of the system and improvement in the farmer's quality of life. Before implementing this system it is necessary to pay attention to a few details. The production of vegetable seeds is a very specialized activity, usually performed by companies with high technological and infrastructure levels. Its success is directly linked to three important factors: a) availability of cultivars, usually from genetic improvement programs, either public or private; b) specific climatic conditions for each species); and c) production technology. All these factors will influence the achievement of high quality seeds, in genetic, physiological, physical or sanitary aspects.
