It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country.

    Mite fauna of agriculturally important crops in Himachal Pradesh
    (palampur, 2021-04-01) C.S., Jayaram; Sharma, Pawan K.
    Investigations on “Mite fauna of agriculturally important crops in Himachal Pradesh” were undertaken in different agro-climatic zones of Himachal Pradesh. The results yielded 78 species of mites comprising 22 phytophagous mites belonging to three families and 56 predatory mites belonging to seven families. Phytophagous mites belonging to the three families (Number of species / Total number of species) viz., Tetranychidae (11/22), Tenuipalpidae (7/22) and Tarsonemidae (4/22). The predatory mites reported during the present study under the seven families were viz., Phytoseiidae (26/56), Ascidae (3/56), Anystidae (3/56); Erythraeidae (4/56), Iolinidae (2/56); Stigmaeidae (14/56) and Tydeidae (4/56). In all 50 species comparing, 43 predatory mites and 7 phytophagous mites were added to the checklist of the mite fauna of the Himachal Pradesh. Diversity indices values were more in case of Tetranychidae under phytophagous mites, Phytoseiidae had maximum diversity values under Mesostigmata and Anystidae had more diversity values under prostigmatid predatory mites. Polyphagotarsonemus latus was found to be the dominant species in Zone-I, Tetranychus urticae was dominant in the Zone-II. In the Zone-III, E. prasadi dominated over all other species, and P. sextoni was found to be dominant in Zone-IV. Seasonal abundance of the phytophagous mites on brinjal and chilli revealed that during 2018 the peak population of T. urticae was observed in June at Palampur, Una and Bajaura. While at Sundernagar, the peak population was observed during September. During 2019 the peak population of T. urticae was during July in all the locations. Peak population of P. latus was observed during July in both 2018 and 2019 in Palampur, Una, Bajaura and Sundernagar. Minimum temperature was significatly correlated and also influence the population build up of T. urticae and P. latus at Palampur. In contarary, maximum temperature had more influence on population build up of both the species at Una and Bajaura. But in Sundernagar, population of T. urticae was influenced by minimum temperature and population of P. latus was influenced by rainfall. Amphitetranychus viennensis (Zacher) was recorded as the invasive alien species on persimmon at Katrain. Erythraeus (Zaracarus) lahauli sp. nov., Eryngiopus sp., Euseius sp. nr. chikkamagalurensis and Scapulaseius sp. nr.sorghumae were deviated from the original species and listed as new species to India
