Effect of Selected Physical Parameters of Lignite Substrate on Morphological Attributes, Yield and Quality of Cucumber Fruits Fertigated with High EC Nutrient Solution in Hydroponic Cultivation

Environmentally friendly substrates that are biodegradable may provide an alternative to mineral wool, which is commonly used in hydroponic growing technology. Little known about the relationship between physical characteristics of lignite substrate and cucumber yield. The study analyzed effect bulk density water holding capacity comparison wool EC nutrient solution on plant morphological parameters, yield fruit quality greenhouse cucumber. A positive relation was found mats increase number leaves per week, shoot diameter as well leaf length area (calculated product × width) cucumbers grown this medium. Bulk also affected macro- micro-nutrient content leaves. properties high medium had a significant hardness, color lutein fruits. biologically active compounds fruits depended readily available plants; these parameters were lower compared wool. However, when cultivation, for period 51 days after planting (DAP) there more than 23% nearly 55% new mats.
