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. Objectives To 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.

The study followed the influence of irrigation rate on early and total yields of tomatoes ( Lycopersicon esculentum Mill.) grown in unconventional system, on different types of substrate. Purpose of the study was to recommend variant with lowest cost for irrigation rate to make an early and total production more efficient. The study was carried out in the greenhouse, using the biological material hybrid Cyndel grown on three types of substrate (perlite, mineral wool, cocopeat). We applied three watering rates and have been carried out on biometrical measurements dynamic plant growth, inflorescence formation. Has been registered early and total production for each variant of substrate and watering rate the highest yields were obtained at V3 (119.43 t/ha) at which was apply watering rate b (6560 m 3 /ha). The results showed differences between variants, both with regard to plant height, and the total production in comparison with the rate of irrigation. When using mineral wool and cocopeat substrates were recorded plant height compared with variants that have used perlite. Â
