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.

    Development, characterization and efficacy of bionanocluster of indole acetic acid and cobalt chloride on seed germination and yield in Cotton (Gossypium hirsutum L.)
    (CCSHAU, Hisar, 2023-09) Vikram Singh; Mandhania, Shiwani
    In the present investigation, Co2+ and indole-3-acetic acid were combined to create chitosan- Co2+-IAA BNCs. The mean hydrodynamic diameter, PDI value and zeta-potential of BNCs were recorded as 481.9 nm, 0.536 and +22.00 mV, respectively. Effect of seed priming with 100 ppm BNCs and four time foliar application of 100 ppm BNCs on seed germination, seedling growth, and boll drop was studied in H 1098i genotype of G. hirsutum L. Cotton seeds subjected to BNCs priming displayed higher percent germination and seed vigor index-I (92.14 %) compared to hydroprimed seeds due to elevated activities of glyoxylate cycle enzymes i.e. isocitrate lyase and malate synthase, which increased the conversion of fats to carbohydrates. Four times foliar application of 100 ppm BNCs increased leaf area, plant height, total chlorophyll content, photosynthetic rate, ACC synthase activity, indole-3-acetic acid content, boll number, boll weight ultimately increasing seed cotton yield by 20.37 %. However, ACC oxidase, cellulase, pectinase activities and boll drop significantly decreased compared to control. It is concluded that application of BNCs comprising of chitosan, IAA and Co2+ via seed priming and foliar mode is novel, economical, and environment friendly.
