Bangarwa, K. S.Doha, Amit Singh2016-10-262016-10-262012http://krishikosh.egranth.ac.in/handle/1/82114The present investigation entitled “Studies on growth potential, market trend and wood volume tables of poplar (Populus deltoides) grown in Haryana” was carried out in the Yamunanagar district of Haryana, India. One to 6 years old plantations of poplar (G 48) with spacing’s of 5×4 m, 4×4 m, 6×3 m were selected for recording data in order to find out growth potential (height and DBH). Current annual increment for basal diameter was observed highest in 5 × 4 m spacing during all the six years as well as on the overall basis. The current annual increment for total height were in increasing order up to 4th year in all the three spacing as well as on overall basis. The rate of growth for total height was in decreasing order from 4th year to 6th year in all the three spacing. Ninety one randomly selected trees were sampled to predict the weight and volume table for poplar tree. Four equations were fitted using linear and non linear regression techniques to predict the volume table. Two models (Schumacher and Hall and single-entry) were used to predict the green timber weight. Results were statistically and graphically analyzed. All equations had very good-fit statistics. The Schumacher and Hall model was selected to estimate the volume of standing poplar trees in Haryana. It is not always easy to measure total height of each standing tree, which is both time consuming and cumbersome. Therefore, regression equation of timber volume based on DBH alone was also worked out. Survey of Yamunanagar market was conducted to find out prices of four types of poplar wood pieces. Prices of all the four types of poplar wood pieces for the last four years were recorded from randomly selected ten poplar wood purchasing units. Market survey for poplar wood suggests increasing trend from 2004 for all the four categories (over, under, sokta and dandi). The increase in poplar wood price for the last 3 years was comparatively low.enWood, Biological development, Spacing, Marketing, Markets, Populus, Forest mensuration, Statistical methods, Area, Farming systemsThesis
