Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. 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. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    Effect of seed treatments with polymer and chemicals on longevity of wheat
    (palampur, 2022-11-15) Jyoti, Aparna; Dhiman, K.C.
    The present investigation was done to study the effect of seed treatments on seed quality parameters and further to identify the effective seed treatment for enhancing seed longevity in wheat. The seeds of wheat variety HPW155 were treated with nine different treatments consisting of polymer, fungicides, insecticide, polymer-fungicides and polymer-insecticide combinations. The treated and untreated seeds were stored in three replications for thirty six months after packing in HDPE (High density polyethylene) interwoven non-laminated bags. The evaluation of different seed quality attributes was made at bi-monthly intervals for twelve months (25th - 36th months). The experiment revealed that inspite of seed coating, there is deterioration in seed as well as the seed vigour declined with ageing of seeds. Amongst different seed treatments, seed coated with polymer @ 3.0 ml/kg of seed + vitavax 200 @ 2.0 g/kg of seed (T6 ) was found superior for maintaining quality attributes viz., germination (88.33%), rate of germination (17.86), seedling length (15.11 cm), seedling dry weight (10.42 mg), seedling vigour index- I (1335), vigour index- II (920) and field emergence (69.00%) which was at par with T5 (vitavax 200 @ 2.0 g/kg of seed) for all the above mentioned quality attributes at the end of 36 months of storage in comparision to untreated control (T1). Although these two treatments resulted to maintain the germination (%) above Indian Minimum Seed Certification Standards (IMSCS) upto 36 months of storage, however, it is not advisable to use seeds after 36 months of storage as the field emergence (%) and final plant stand (%) declined significantly
