A fundamental part of crop management lies in a good knowledge of the plant material that is being used and from which it could be used. This means knowing: behaviors, adaptability to the terrain and compatibility of different rootstocks and varieties. Many times this information must be generated on the fly on the farm because there are no data and in other cases it means having a realistic information about the productive potential of a plantation under given conditions.
You can access information of breeders and nurserymen and data from other farms nationally or internationally. It is very important to record phenology data and harvest results in quantity and quality.
