The aim of the study was to evaluate the growth dynamic of Scots pine on the post arable ground under mulch in the third year of cultivation. Planting were carried out on the basis of post arable ground located in the Agro and Hydrometeorology Observatory of the University of Life Sciences in Wrocław. Scots pine plants in the third year of cultivation increased in height from 68.8 cm to 102.5 cm, ie. by 33.7 cm about 49%. The growth rate of pine was the highest in the first part of the growing season (until June 10), when the plant height increased by 30 cm, accounting for about 90% of the total, the annual increment in height. The second biometric parameters studied - the diameter of the trunk - increased in the third year of growing pine from 28.0 mm to 39.9 mm (about 11. 9 mm, ie. about 42%). The growth rate as a trunk diameter was different from that recorded in the case of plant height, because in the first part of the growing pine, wherein the largest increase its height, stem diameter increased by only 29% of the annual growth (ie. about 3.4 mm). ...
The aim of the study was to estimate the variability of biometric parameters in the second year of cultivation of Scots pine on the post arable ground. Planting were carried out on the basis of post arable ground located in the Faculty Agro and Hydrometeorology Observatory of the Wrocław University of Environmental and Life Sciences. Scots pine plants in the second year of cultivation increased in height from 43.1 cm to 53.39 cm, 10,29 cm, i.e. 24 % ie. The growth rate of pine was the highest in the first part of the growing season (until June 14), when the plant height increased by 7.69 cm, accounting for about 75% of the total, the annual increment in height. The second biometric parameters studied - the diameter of the trunk - increased in the second year of growing pine from 13.16 mm to 23.36 mm (by 10. 2 mm, ie. about 77 %). ...
