Effect on the Influence of Watering Rate and the Type of Substrate on the Production of Tomatoes (Lycopersicon Esculentum Mill.) Grown in the Greenhouse in Unconventional System

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 super(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.
