| Abstract:
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). | |
