EFFECT OF DIFFERENT IRRIGATION SYSTEMS ON YIELD OF TOMATOES GROWN UNDER PLASTIC GREENHOUSES
The highest yield of tomatoes was obtained with micro-jet irrigation system. Drip irrigated tomato plants produced lower yield than those irrigated by micro-jet but the difference was not significant. Lowest yield was obtained with hand watering by hose.
Water use for irrigation by all drip systems was about 35% lower as compared to hand watering and about 25% lower than the micro-jet system. The water consumption per kg of tomato fruit was lowest for drip systems (22–26 l kg) and highest for hand watering (41 l kg).
