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 coating with polymer and chemicals on seed storability of maize (Zea mays L.)
    (Palampur, 2022-11-18) Divya; Dhiman, K.C.
    The present investigation was done to study the effect of seed coating on seed quality parameters during storage and further to identify the effective seed coating treatment for enhancing seed storability of maize. The seeds of maize variety Bajaura Makka 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 twelve 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 (March 2021 - March 2022). The experiment revealed that irrespective of seed coating, the seed deteriorated and the vigour declined with the advancement in storage period. Amongst different seed treatments, seed coated with polymer + vitavax power (containing thiram 37.5% and carboxin 37.5%) @ 2.0 g/kg of seed (T6) was found significantly superior for all seed quality parameters viz., germination (97.30 %), rate of germination (47.40), field emergence (88.60 %), seedling length (37.00 cm), dry matter of seedling (65.73 mg), seedling vigour index - I (3589.00) and seedling vigour index - II (6375.81) which was at par with T5 - vitavax power (containing thiram 37.5% and carboxin 37.5%) @ 2.0 g/kg seed for all the above mentioned seed quality parameters in comparison to untreated control (T1). Hence, combination of polymer with vitavax or vitavax alone can effectively be used to prevent the rapid deterioration of seed during storage period as they maintained the seed quality attributes for twelve months.
