Research on the Influence of Substrate Type and the Amount and Number of Irrigations Applied on the Growth of Tomatoes in the Greenhouse

The research aims to present the evolution of localized irrigation methods, according to this process the modern equipment will be tested. This study will investigate the technical and economic efficiency compared to the currently used methods in the greenhouse. The study was conducted in the research center Hortinvest,University of Agronomic Sciences and Veterinary Medicine of Bucharest. The biological material used in this study case was the tomato hybrid Cindel. To obtain reliable conclusions we will provide the same quality parameters of irrigation water, using the same technology and culture in all experimental variants. The efficiency techniques that we adopted will be judged by the size of the achieved production and by assessing the quality indices of production. During the growing season vegetative growth and biometric measurements will be monitored and the duration of each phenological phase it will determine, depending on the technique used.ObjectivesTo establish the optimum irrigation, to determine the relationship between the type of substrate and the height of tomato plants, to determine the number of irrigations applied during the growing period, to determine the relationship between crop substrate and plants growth. The research subjectis are also supported by the research program POSDRU / 159 / 1.5 / S / 132765.
