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.

    BIOCHEMICAL AND RESIDUE STUDIES OF TEMBOTRIONE IN MAIZE
    (CSKHPKV. Palampur, 2020-01-31) SAPEHIA, SHAILA; Sharma, Neelam
    A field experiment was laid out in randomized block design (RBD) consisting of five treatments viz. tembotrione 60g/ha, tembotrione 120g/ha, tembotrione 240g/ha, atrazine 1.5kg/ha and control to study the “Biochemical and residue studies of tembotrione in maize” in the Department of Agronomy, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur during kharif season, 2019. Maize plant samples were collected at monthly intervals (i.e. zero (2 hrs), 30, 60 days after the herbicide application) and at harvest for biochemical analysis and grain samples at maturity of crop for quality indices and for residue studies. Soil samples were collected at zero (2 hrs), 1, 3, 5, 7, 10, 15, 30, 45, 60 days and at harvest for the residue studies. Protein content in maize plant was not influenced very distinctly with applied treatments, except at 30 days. However, a numerical increase in total protein content was noticed in tembotrione treatments over control. Total chlorophyll, total carotenoids and total carbohydrates content in maize leaves increased significantly with applied tembotrione treatments and maximum increase was noticed in treatment tembotrione 120g/ha. A significant increase in total carbohydrates content in maize grain over control was observed in all the herbicide applied treatments. The residue data of tembotrione generated in present investigation indicated that tembotrione 60g/ha, tembotrione 120g/ha and tembotrione 240g/ha persisted in soil up to 30, 45 and 45 days, respectively. Approximately 75 per cent of applied herbicide in soil dissipated within 15 days after herbicide application. The dissipation of tembotrione in the soil at three rates of application i.e tembotrione 60g/ha, tembotrione 120g/ha and tembotrione 240g/ha followed first order kinetics and the half –lives ranged from 9 to 14 days. Residues of tembotrione were below detectable levels i.e. ≤0.025µg/g in maize grain and maize stover
