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 different barley varieties to nitrogen levels
    (CCSHAU, Hisar, 2021-03) Adhikari, Shrijana; Bhagat Singh
    The present investigation entitled “Response of different barley varieties to nitrogen levels” was conducted during the Rabi season during 2019-20 at research farm of Wheat and Barley section, CCSHAU, Hisar. The experiment was laid out in split plot design with three replications. The main plot treatments were six levels of nitrogen i.e. 0, 20, 40, 60, 80 and 100 kg N ha-1 and sub plot treatments consists of four barley varieties (BH 946, BH 393, BH 885 and Karan 16). Results indicated that application of nitrogen and varieties had significant effects on plant growth parameters such as plant height, number of tillers and dry matter accumulation. Higher level of nitrogen significantly influenced the yield attributes and were maximum when 100 kg N ha-1 was applied, however, it was at par with 80 kg N ha-1. The maximum grain yield (41.40 q ha-1) was recorded with application of 100 kg N ha-1 which was significantly higher as compared to lower levels of nitrogen except 80 kg N ha-1. The application of 20, 40, 60, 80 and 100 kg N ha-1 increased the grain yield by 44.83, 59.02, 67.13, 71.14 and 72.29 per cent, respectively over control. Nitrogen application did not impart any significant differences in harvest index. The protein content was significantly increased with increasing nitrogen levels and was found significantly higher (10.48 %) at 80 kg N ha-1 over lower levels of nitrogen but at par with 100 kg N ha-1. The hectoliter weight was significantly higher (64.17 kg hl-1) at 100 kg N ha-1. The net return and B C ratio were maximum with the application of 100 kg N ha-1. Among varieties, number of effective tillers and 1000 grain weight were found significantly higher in two rowed barley variety BH 885, whereas BH 946 recorded maximum number of grains per spike. The grain yield was significantly higher in BH 946 (33.11 q ha-1) which was at par with BH 393 but significantly higher than BH 885 and Karan 16. BH 946 gave highest net return (Rs. 40995 ha-1) and B C ratio (1.63) as compared to other varieties.
