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.

    Effect of planting season on seed yield, yield components and seed quality in maize hybrids (Zea mays L)
    (CCSHAU, 2018) Nidhi; Bhuker, Axay
    Four maize hybrids produced during rabi and kharif seasons were evaluated for their performance for different viability, vigour and yield parameters viz. standard germination, seedling length, seed weight, seed density, seedling dry weight, vigour index-I, vigour index-II, accelerated ageing test, electrical conductivity, tetrazolium test, dehydrogenase activity test, catalase activity test, peroxidase test, lipid peroxidation test, protein content, field emergence index, seedling establishment, number of leaves, number of cobs, cob length, plant height, days to 50 % tasseling, days to 50% silking, number of seeds per cob and seed yield to assess the effect of planting season on seed yield, yield components and seed quality in maize hybrids. The rabi season produced seed showed superiority over kharif season for all the seed quality and yield parameters. Among the hybrids, HQPM-5 had the top rank for almost all the vigour, viability and yield parameters in both the seasons (rabi and kharif) indicating its superiority over other hybrids. Standard germination was found significantly and positively correlated with most of the seed quality parameters except electrical conductivity and lipid peroxidation in both the seasons. Electrical conductivity and lipid peroxidation was found significantly and negatively associated with most of the parameters recorded in laboratory and field. On the basis of correlation study, it can be concluded that the viability test like tetrazolium test, electrical conductivity test, dehydrogenase activity test, accelerated ageing test, catalase activity test and lipid peroxidation test can be used as reliable predictor of standard germination in maize and rabi season can be considered as a better option for the production of quality seed in maize in Haryana
