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.

    Nitrogen management in wheat for increasing yield and its use efficiency
    (CCSHAU, Hisar, 2023-07) Gulshan; Rajpaul Yadav
    Study on “Nitrogen management in wheat for increasing yield and its use efficiency” was conducted at research farm, Department of Soil Science, CCSHAU, Hisar Haryana. The location of experimental site was 29o16‟N latitude and 75o7‟E longitude in the North-West part of India. The objective of this study to evaluate the effect of different nitrogen management practices in wheat for enhancing yield and nitrogen use efficiency. The experiment was designed with seven treatments comprising of control, recommended dose of nitrogen (RDN), 125% of recommended dose of nitrogen, soil test based nitrogen management, STCR based nitrogen management, 100 kg urea ha-1+LCC based nitrogen application at 2nd irrigation and LCC based nitrogen application at 1st and 2nd irrigation with three replications in a randomized block design. The highest grain yield (3600 kg ha-1) was obtained when 187.5 kg N ha-1 was applied in 125% RDN based treatment. However, the grain yield obtained in LCC-based treatment was statistically at par with RDN and soil test based treatment. Consequently the N, P and K content and uptake was higher in 125% RDN and STCR based nitrogen management practices. The chlorophyll content and gluten content was also significantly high in STCR treatment. The chemical properties of soil-pH, EC, OC and available P didn‟t differ significantly among different nitrogen management practices after harvest while available K was highest in soil sample of every treatment after harvest except control in comparison to their amount before sowing of the crop. The available nitrogen increased up to 40 DAS in all treatments except control while in 125% RDN it increased up to 70 DAS and then started declining progressively in all management practices. After harvest of the crop the available nitrogen was significantly higher in STCR-based treatment while available K was significantly higher in both LCC-based treatments. The urease enzyme activity had followed the same trend as was followed by available nitrogen during different crop growth stages. Initially, it increased with the supply of urea up to 70 DAS except for control and afterward, it started declining progressively in all treatments. However, the significantly highest urease activity in soil sample after harvest was recorded in STCR-based treatment, and on the other hand LCC based treatment was at par with RDN-based treatment in terms of urease activity after harvest. The consumption of only 104 kg N ha-1 in LCC-based treatment without sacrificing yield over RDN resulted in its higher agronomic and recovery efficiency. As per economic analysis, it was found that the STCR-based treatment incurred a higher cost of cultivation while higher gross returns and benefit cost ratio was obtained in 125% RDN-based management of nitrogen. However, nitrogen management with the help of LCC proved an economically viable option over application of a recommended dose of nitrogen.
