Whether we're talking about cold or hot global zones, for several years global warming is causing weather extremes and frequent conditions that have far-reaching influence on agriculture, farmers and horticulture in various zones.
These phenomena force farms to switch to tunnel covered crops, greenhouses and nets. In open field crops the use of mulch films has expanded, which also helps farmers to cope with weather damage and to maintain high yields by conserving ground moisture.
The conference and exhibition accompanying it were devoted to presenting research results on apple growing, carried out by student investigators from Brazil and abroad. The Ginegar Company presented results of experiments with different types of netting, including photo-selective nets, from various areas around the globe, like Israel, South Africa, Spain, Italy, Chile, and the U.S., strengthening the hypothesis that spreading nets over orchards protects the trees from both frost and hail as well as extreme heat that causes heat stroke.
Use of nets helps to increase yield, since the nets maintain ground moisture, with less ground evaporation, resulting in efficiency of water consumption by the trees. Indeed, all the studies done in all zones and all crops – apricots, pomegranate, bananas – demonstrated that using nets enables reduction of irrigation.
In a project currently being carried out, the company's staff are striving to develop a system for quick opening and closing of the nets that would allow better control for the grower in operating the orchard, such as closing the nets only after the fruit has set and the bees have done their work, with opening at the end of the season prior to snowfall.
Additional advantages enjoyed by farmers switching over to nets: strong, well-developed trees, high quality, smooth, better looking, larger fruit, protected from pests, with greater income produced by the orchard for the farmer. (The experiments also showed that farmers recoup the cost of installing nets relatively soon, between one to two years).
Given that farmers are forced to cope with difficult climatic conditions, the main question is not whether to cover the plants, but what is the most appropriate net for each crop. It's a fact that in more and more places farmers realize that use of nets helps them to cope with weather fluctuations, to maintain high level yield, to maintain assurance of orderly, quality supply to retail chains, and profitability.
