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.

    Study of microclimate in Pearl millet genotype under different growing environments
    (CCSHAU Hisar, 2022-07-26) Harshana; Anil Kumar
    Field experiment entitled “Study of microclimate in pearl millet genotype under different growing environments” was conducted during kharif season (2020 and 2021) at research farm, Department of Agricultural Meteorology, CCS HAU, Hisar which is located at 29° 10´ N latitude, 75° 46´ E longitude with 215.2 m altitude. The experiment was carried in a factorial RBD design that comprised of three sowing dates viz. D1 – 2nd fortnight of June; D2 – 1st fortnight of July and D3 – 2nd fortnight of July; and three different genotypes viz. V1 (GHB 558), V2 (HHB 67 improved) and V3 (HHB 272) during crop season 2020 and 2021, respectively with four replications. Crop growth and development i.e. the phonological phases, plant height, no. of tillers/ plant, leaf area index, CCI and dry matter accumulation were higher in D1 and V1 under different growing environments and genotypes. Among all the treatments, D1 recorded higher grain (3726 and 3576 kg/ha ) and biological yields (13863 and 13442 kg/ha) ) during crop season 2020 and 2021, respectively. The higher grain and biological yields were recorded during crop season 2020 as compared to crop season 2021. The highest grain and biological (3767 and 13444 kg/ha during crop season 2020) and (3642 and 13043 kg/ha during crop season 2021) were recorded in V1, respectively. Maximum soil moisture content was recorded in early sown crop during both the crop seasons. 2021 crop seasons had high soil moisture content as compared to crop season 2020. Among different growing environments, morning soil temperature was observed significantly higher in D1 at 5 and 10 cm depth and lower was in D3 at 5 cm depth during both the crop seasons. Among different growing environments, the higher chlorophyll content value was significantly observed in D1 as compare to other sowing dates, highest intercepted PAR were observed in D1 sown crop at various growth intervals during both crop seasons. Among genotypes during both crop seasons crop at various growth intervals, V1 (GHB 558) received higher intercepted PAR. All the agrometeorological indices were consumed more by D1 at different phenophases among different growing environments during both the crop seasons. Among genotypes, the indices were consumed highest by V1 (GHB 558). Among micrometeorological studies, the absorbed PAR was higher in D1 and was maximum in V1 (GHB 558) under varying growing pearl millet genotypes during both crop seasons. The net radiation was higher at anthesis stage. The higher canopy temperature Tc was observed late sown crop during two years study. The temperature profiles were lapse within the canopy throughout the day. The relative humidity profiles were lapse throughout the day inside the crop canopy but profiles were near iso-humic in the morning at 9:00 hours at different crop growth stages during both crop seasons.

    Long term Rainfall Behavior in Western Agro-climatic zone of Haryana
    (CCSHAU, 2019) Harshana; Raj Singh
    The present research study entitled „Long term rainfall behaviour of western agro-climatic zone of Haryana‟ was undertaken to study seasonal characteristics, extreme events and trend of rainfall. It also analyzed relationship between rainfall and yield performance of major crops in Western Haryana. In Western Agroclimatic Zone, weekly mean maximum rainfall in 28th SMW was observed at Bhiwani (29.7 mm), Jhajjar (38.4 mm), Mahendragarh (34 mm), Rewari (42.4 mm), Jind (36.3 mm) and Rohtak (32.2 mm), respectively whereas in 31st SMW at Fatehabad (23.3 mm), 29th SMW at Hisar (29.0 mm) and in 27th SMW at Sirsa (25.6 mm). Monthly mean maximum rainfall in July was observed at Bhiwani (109.3 mm), Hisar (109.3 mm) and Jind (126.9 mm) while in August at Fatehabad (78 mm), Jhajjar (152.6 mm), Mahendragarh (115.7 mm), Rewari ( 146.3 mm), Rohtak (134.3 mm) and Sirsa ( 86.2 mm) respectively. In overall western agro-climatic zone, 332.9 mm, 14.2 mm, 23.1 mm and 22.3 mm rainfall was received by SW, NE ,Winter and Summer season respectively during the entire period of study. Annual mean rainfall was highest at Jhajjar (524.4 mm) and lowest in Sirsa (313.2 mm) while CV (%) value was highest at Rohtak (51.4 %) and lowest in Hisar (27.9 %) respectively. All stations of western Haryana exhibited decreasing annual rainfall trend where annual rainfall was decreasing significantly in four stations viz. Fatehabad, Jhajjar, Rohtak and Sirsa @ -3.08 mm, -7.54 mm, -12.25 mm and -4.78 mm per annum respectively. Post Monsoon rainfall exhibited significant decreasing rainfall trend @ -0.33 mm per annum in Rohtak. Monsoon season exhibited significant decreasing rainfall trend @ -3.42, -5.58, -9.12 and – 3.23 mm per annum in Hisar, Jhajjar, Rohtak and Sirsa, respectively. Winter Season exhibited significant decreasing trend @ -0.68 mm and -0.40 mm per annum at Rohtak and Sirsa. Pre monsoon season showed increased trend in most of the stations. Value of standard deviation and coefficient of variation was high on temporal and spatial scale which indicated highly variable rainfall in the western agro-climatic zone during study period. Extreme rainfall events mostly occurred during monsoon season which received highest rainfall. Crop seasonal rainfall and mustard and chickpea productivity was negatively correlated in all stations may be due to outbreaks of insects and pests in high temperature and humidity conditions caused by high rainfall. Crop seasonal rainfall and wheat productivity was positively correlated in four stations (Bhiwani, Jind, Mahendragarh and Rewari) and negatively correlated in rest of the 5 stations (Fatehabad, Hisar, Jhajjar, Sirsa and Rohtak).
