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.

    Response of biofertilizers on growth, flowering and yield of chrysanthemum
    (CCSHAU, 2013) Anop Kumari; Goyal, R.K.
    The present investigation entitled “Response of biofertilizers on growth, flowering and yield of chrysanthemum” was conducted in the screen house of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2011-12 and 2012-13. The investigation composed of three experiments viz., (i) response of biofertilizers in combination with nitrogen on growth and flowering of chrysanthemum (four levels of nitrogen, i.e., 0, 10, 20 and 30 g/m2 and two biofertilizers viz., Azotobacter and Azospirillum), (ii) response of biofertilizers in combination with phosphorous on growth and flowering of chrysanthemum (four levels of phosphorous, i.e., 0, 10, 15 and 20 g/m2 and two biofertilizers, i.e., PSB and mycorrhiza) and (iii) response of single and coinoculation of PGPR on growth and flowering of chrysanthemum (three strains of Bacillus viz., SYB101, SB155 and SB127 and three strains of Pseudomonas, i.e., WPS73, CPA152 and P20). All the possible combinations of nitrogen levels and biofertilizers were found to have significant influence on growth, flowering and yield parameters of chrysanthemum. The minimum number of days taken to first flowering, maximum flowering duration, flower size, number of flowers per plant, flower yield per plant and number of suckers per plant were recorded with nitrogen 20 g/m2 along with Azospirillum. An increase in nitrogen content was noted with increased application of nitrogen, whereas, phosphorus and potassium content of plant decreased. Phosphorus 15 g/m2 along with PSB was found most effective for reduced number of days taken for first flowering, longest flowering duration, maximum number of flowers per plant and flower yield per plant as well number of suckers per plant. Nitrogen and phosphorus content of plant increased significantly with increasing levels of phosphorous, and the maximum content was observed with phosphorous 20 g/m2. Different strains of Bacillus and Pseudomonas significantly influenced the observed parameters of chrysanthemum. The results indicate that Bacillus strain SB127 and Pseudomonas strain CPA152 were found potent in increasing all growth, flowering and yield parameters. The SB127 + CPA152, SB155 + CPA152 and SB127 + P20 combinations of Bacillus and Pseudomonas strains showed best results in chrysanthemum.
