|Review of effects of physical factors of the environment on horticultural crops|
- A slight wind is necessary to replenish Carbondioxide near plant surface.
- Wind carries oxygen away from the plant.
- Less wind, less evaporation, less water requirement.
- Wind can be a limiting factor in vegetables production where strong winds (a ver. Wind speed of 7.2 km/hr) occur e.g. Typhoons (wind speed of 60 km/hr)
- Use of windbreaks (shelter belts) minimize damage, a relatively slow wind.
- Dusting plants - affects rate of photosynthesis of coating the photosynthesizing leaves and green stem.
- May blow away pests and diseases thus carry pests to or away from crop.
- May interfere with farm operations e.g. spraying, etc..
- May aid in pollination.
