Actions we must carry out while implementing field food safety programs:
A good quality seed is a highly viable seed; that is, a seed which is able to develop a regular seedling even under unsuitable environmental conditions, as it may happen in the open field.
Quality of the seed to be sown is essential to achieve a good plant establishment and is the first step to achieve optimal growing. The most important quality attributes considered are feasibility, germination, vigor and food safety.
That is, seeds must be able to germinate (alive embryo) and develop a normal seedling under optimal planting conditions. The death of the embryo may occur due to natural wear caused by long-term storage, means of storage and preservation. For example, under low environmental humidity, high temperatures lead to low seed quality. In the same way, the manner in which the seed was harvested and transported becomes factors that influence feasibility. If the seed cover is damaged, germination will not occur.
Germination of a good quality seed must be fast and uniform, as we are seeking to obtain fast soil coverage; this is necessary due to the competition with weeds and therefore, it helps us reducing losses due to the attack of pathogens present in the soil in the form of fungi, bacteria and insects, and also to avoid being eaten by rodents and birds.
It is the ability of a seed to germinate under unsuitable planting conditions for its species, other than being able to develop plants uniformly and strong under unfavorable environmental conditions. A seed with good vigor preserves a good germination percentage after a long storage time.
Food safety of a seed ensures germination, as it must be maintained fungi, bacteria and virus-free; ensuring in this manner that no diseases are being spread and no further problems are caused, which leads to a loss in performance.
To ensure a seed meets with such attributes and/or characteristics, the use of certified seeds is recommended, as these have plenty of advantages, both in the agronomic and plant health areas; making them the best option for farmers, and obtaining greater productivity when compared to native seeds. Also, these ensure homogeneous and uniform germination.
Another advantage is that they are impurity-free (seeds from other species, weeds, foreign matter) and they are subjected to chemical treatments preventing the presence of pests and diseases.
