Bionica Potato

On the last Tuesday we harvested the potatoes at the BioRomeo. The potato is one of the principal products to the farm. Here are produced some kinds of potatoes, besides the purple potatoes.
The potatoes harvest on Tuesday afternoon are Bionica potatoes, this is a resistent variety Phypotphthora and was select at Niek Vos' farm. The duration of the select process was about 35 years. 
Phypotphthora is the causative agent of the disease known as "potato late blight" and is one of the most destructive diseases of this culture. The disease mainly attacks the leaves and crop destruction by this disease can cariar 10 to 100% depending on the degree of susceptibility of the cultivar.
The average productivity of the harvested area on Tuesday was between 40 and 50 ton/ha.
