OPTIMIZATION OF WATER CONSUMPTION FOR THE IRRIGATION OF THE TOMATO FIELD IN GREENHOUSES ON THE TERRITORY OF BALENI VILLAGE, DAMBOVITA COUNTY
2014
The topic of this work is of actuality for vegetable growers in Dambovita County and beyond, given the problem of using freshwater resources with its biological and economic implications. The research aimed at the establishment of the irrigation regime in cold greenhouses and solariums for private producers in Baleni village, Dambovita county and not only as a basic element for watering schedule in order to obtain reliable production of quality and higher quantity only in the context of maintaining the water balance of soil at constant parameters. Experiments were conducted within the Baleni village area in Dambovita county on a group of solariums with a total developed area of 2500 square meters. We analyzed quantitative and qualitative issues for two types of table tomatoes according to the irrigation regimes applied for a period of three years. The varieties of table tomato were Jadelo and Tangra which were applied with irrigation watering regimes with a recurrence of 3 and 6 days, for 3 watering rules corresponding to values of 50% ETM, 100% and 150% ETM ETM. For any addition to the watering rate it corresponded a significant increase in production of tomatoes by increasing the number of tomatoes per plant and the weight gain of each tomato, especially to reduce the number of low quality tomatoes. Corresponding to values of 50, 100, 150% of ETM, there was an annual average production of 61, 82 and 91 tons / ha, with a total of 17, 21 and 22 tomatoes per plants with an average weight of 92, 100 and 105g / fruit. The research paper shows that in terms of restrictions on the consumer, ie the amount of irrigation water for values corresponding to 50% of ETM, specific to agricultural drought, there can be a considerable tomato production of 61 tons / ha for solariums.
