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 seed germination and storability of Rohida
    (CCSHAU, 2008) Ravi Kant; Bimlendra Kumari
    The present investigation was carried out on Rohida seeds. The seed material was collected from four different seed sources viz., Churu, Ding Mandi, Jhumpa and Rajgarh. The present study was conducted during 2005-06 at nursery area of Department of Forestry and laboratories of Department of Seed Science and Technology and Department of Forestry CCS HAU, Hisar. The objective of investigation was: To evaluate different seed sources for seed viability, germination and seedling growth behavior; To determine the storability of Rohida seed. Various morphological characters of Rohida trees from four different geographical locations were recorded and seeds were collected from the selected trees. Seed quality parameters such as seed size (length and breadth), colour, test weight, germination percent (74 %), speed of germination (13.63 %), radicle (6.30 cm) and plumule length(5.30 cm), seedling dry weight (415.60 mg), dehydrogenase activity (1.40), electrical conductivity vigour index I and II were studied of freshly harvested seeds and then stored in ambient storage conditions. The seeds of all the four different places were aged artificially at various time (24, 48 and 72 h) and temperature (40±1oC) variables. Accelerated ageing of seeds for 24 h at 40±1oC produced a clear separation and provide better results. Then seeds of all the four different places were tested to study physiological basis for loss in viability. It was observed that standard germination, seedling length, dry weight, vigour index I, vigour index II and viability percentage was found maximum in Rajgarh seed source.
