EFFECT OF DIFFERENT IRRIGATION SYSTEMS ON YIELD OF TOMATOES GROWN UNDER PLASTIC GREENHOUSES

S. Kaniszewski, J. Dysko
The effect of different irrigation systems on the yield of tomatoes was investigated. Drip irrigation systems such as capillary system, twin-wall and combination emitter was compared with the micro-jet system and hand watering by hose. The watering was applied when soil suction reached 0.02 MPa, at the amount of 2 l per plant.

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).
