GREEN HOUSE TOMATOES :
According to the greenhouse tomato project, one of the activities the programme is supporting to help increase the incomes of rural households, is borrowed from Israel, where the country has most of its agriculture under greenhouses due to scarcity of water and land. It is also widely practised in the United States. According to project  technical advisor, growing crops under greenhouses has many advantages, among them the ability to produce huge quantities on a small piece of land and continuous harvesting. The tomatoes have a shelf-life of 21 days compared with 14 days for those grown in the open.
It takes a shorter period — two months — for greenhouse-produced tomatoes to mature, while it takes a minimum of three months with outdoor farming.
Due to controlled irrigation and temperatures, the crop sports a continuous output of flowers and fruits, all at different stages.
One plant has a potential of up to 15 kg at first harvest, going up to 40 kg by the time it has completed its full cycle — recommended at one year.
The plant vines are supported inside the greenhouse with sticks and strings, growing up to 5 metres in height. 
Tomatoes are generally highly susceptible to diseases requiring heavy application of pesticides but under the greenhouse growing techniques, which come with basic training on hygiene, most of common infections are easily kept at bay. Also kept at bay are insects and other pests known to invade plants as well as weeds.
Apart from huge savings on crop protection chemicals, which constitute a huge part of production costs, less labour is employed in a greenhouse, while exposure to chemical toxins associated with application is minimised or eliminated altogether. It is also good for the environment.
