Effect of irrigation on some growth parameters of cup plant and dehydrogenase activity in soil
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2015, Vol 47, Issue 4
Abstract
A field experiment carried out in two vegetation seasons in the years 2012 and 2013 on very light soil at Kruszyn Krajeński, in the vicinity of Bydgoszcz (Poland). Investigation of the influence of drip irrigation on some growth parameters of three- and four-year-old cup plant (Silphium perfoliatum L.) and on the activity of dehydrogenase participating at cycling in soil was examined. The cup plants were cultivated from the micropropagation seedlings. Experiments were performed as one factorial in four replications. The factor of the experiment was the following variants: O – without irrigation (control plots), D – with drip irrigation. Drip irrigation was scheduled according to tensiometers indications. Irrigation significantly increase the height of the plants, the length of internode, the thickness of the stalk, the fresh weight of the shoots, and the number of the leaves and flowers. Irrigation also increased the transpiration leaf area and the dry matter content. In the soil sampled under cup plant in 2012 there was found a greater activity of dehydrogenases in soil derived from non-irrigated objects.
