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.

    Simulation of wheat (Triticum aestivum L.) growth and yield under different environments
    (CCSHAU, 2018) Nayak, Mukesh Kumar; Raj Singh
    Field experiment entitled “Simulation of wheat (Triticum aestivum L.) growth and yield under different environments” was conducted during Rabi season (2014-15 and 2015-16) at research farm of Department of Agricultural Meteorology, CCS HAU, Hisar (29° 10¢ N, 75° 46¢ E and altitude 215.2 m). The experiment was comprised of four sowing dates main plot treatments namely D1 (5th November), D2 (20th November), D3 (5th December) and D4 (20th December); four irrigation levels sub plot treatments comprising. The experiment was laid out in strip plot design with three replications. Different agrometeorological indices viz. GDD, HTU, PTU and PTI accumulation was significantly higher under D4 (20th December) sowing date at all the phenophases in comparison to the other dates of sowing. The requirement of heat units were more in higher level of irrigation application. Highest PAR and RUE values obtained in D1 (5th Nov.) date of sowing with I4 irrigation as compared to other treatments. The maximum RUE was obtained under D1 (5th Nov.) sown crop with more irrigation level (I4). The highest plant height, dry matter accumulation and LAI was recorded under D1 and I4 irrigation level with maximum CCI at anthesis stage. The yield and yield attributes viz. no. of tillers per clum, length of spike, no. of grains per spike, no. of spikelets per spike, test weight, grain yield, straw yield and biological yield significantly higher under early sowing (D1) with I4 irrigation level. Weather variables showed a positive and negative correlation with yield and yield attributes. Simulation performance of model showed an overestimation with days to anthesis, leaf stem weight at anthesis, physiological maturity while grain yield, straw yield and harvest index showed a over-underestimation of results. Sensitivity of CERES- wheat model showed a gradual decrease in grain yield if there were gradual incremental units like maximum temperature, minimum temperature, solar radiation and CO2 level to normal values.
