Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Studies on growth potential, market trend and wood volume tables of poplar (Populus deltoides) grown in Haryana
    (CCSHAU, 2012) Doha, Amit Singh; Bangarwa, K. S.
    The 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.
