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.

    Screening of white button mushroom, agaricus bisporus (Lange) singer strains against mushroom flies and their management through botanicals
    (CCSHAU, 2005) Parveen Kumar; Mrig, K.K.
    The present investigation was undertaken for screening of white button mushroom, Agaricus bisporus (Lange) Singer strains, evaluating botanicals for management of mushroom flies and studying the population dynamics of flies. The material for screening comprised of five strains of A. bisporus, eight medicinal plant extract, two insecticide and a light trap with a yellow polythene and 15 watt yellow bulb. These experiments were carried out at Department of Plant Pathology and Department of Entomology, CCS Haryana Agricultural University, Hisar during 2004-05 season and CRD design with three replication was followed for layout. There was no infestation of phoridfly whereas maximum (16.67%) and minimum (7.25%) infestation of sciaridfly was in S-791 and P-31, respectively, in the early crop. Infestation of phorid fly was maximum (40.51%) in S-791 and lowest (30.95%) in S-100 whereas sciarid infestation was maximum (22.49%) in S-791 and minimum (10.98%) in P-31, in late crop. All the strains showed moderate feeding by sciarid fly larvae except S-791 which had highly feeding while all the strains showed highly feeding by phorid fly. Number of sciarid larvae per infested fruiting body were maximum (5.2) in S-791 and minimum (2.9) in P-31 during early crop while in the late crop, maximum (7.1) were in S-791 and minimum (4.1) in HU-3. Phorid larvae were maximum (22.7) in S-791 and minimum (12.7) in S-100 in the late crop. Sciarid larvae in spawn-run compost cup were maximum (16.2) in S-791 and minimum (10.0) in S-11 whereas maximum (26.5) number of phorid larvae were in S-791 and lowest (18.7) were in S-100. Spawn run time was longer in all the botanical treatments over control. Maximum spaw-run inhibition (3.00 day) was noticed in Ashvagandha treatment while minimum inhibition (0.33 day) was in Sarpgandha treatment. It was shorter by 0.33 day in endosulfan 35 EC treatment. All the botanicals treatments decrease the per cent infestation of mushroom flies significantly over the control but no botanical was at par with checks (Endosulfan 35 EC and Nimbecidine 300 ppm). Minimum infestation (21.56%) was observed in neem treatment whereas maximum (43.80%) was in Gurmar treatment. No botanical treatment gave the high yield over checks. Yield was maximum (10.20 kg/q compost) in Turmeric treatment and minimum (8.66 kg/q compost) in Gurmar and Senna treatments. Avoidable losses was highest (14.4%) in Turmeric and there was no avoidable loss in Gurmar and Senna. Phorid fly population shows positive correlation r= 0.553 with temperature while sciarid fly had no correlation with temperature having r= 0.036.
