ISHS Acta Horticulturae 244: IV International Symposium on Quality of Vegetables

GROWING AND HARVESTING = PRODUCING AND MAINTAINING QUALITY

Author:   C. Graf-Grote
Abstract:
The key for any producer today must be to have a qualified view of what he wants to achieve by the time the crop is harvested, i.e. his end product. Whether it is then being prepared further by packers, transported, cooled etc. is an entirely different matter. The producer himself is concerned with obtaining the best possible product harvested in the bin as a first and foremost, even if he looks after the storage thereafter as well, and he must have a perception of what the quality needs to be. I will try and look at the various components which make up a good end result under four main headings:
  1. Basic Resources

    Land and climate, water, seed, fertiliser, chemicals, labour and capital.

  2. Experience and Skill

    Making decisions, the grower's touch.

  3. Quantifying and Qualifying the Optimum Crop

    The real value, not the grower's perception, market considerations, cost.

  4. Harvest

    Prevention of damage by operator or skill and the correct equipment.

    Transportation, weather influences, reducing losses, preventing slippage.

Let's look at our most basic resources to start with. Above all we need to consider the quality of land. For horticultural crops it has to be free draining, easy to work, perennial weed free. It should also be disease free, for example high eelworm population hinders the cropping or makes it very expensive with yield reduction. Onion white rot carries similar problems. Is the soil acid? Are there mineral deficiencies? How stonefree is it? Has it got
