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.

    STUDIES ON VESICULAR ARBUSCULAR MYCORRHIZAE (VAM) IN MEETING PHOSPHORUS NEEDS OF OKRA- WHEAT SEQUENCE IN TYPIC HAPLUDALF
    (CSK Himachal Pradesh Krishi Vishavavidyalaya, Palampur, 2009) KUMAR, SUDHIR; Sharma, C.M.
    The present investigation entitled “Studies on Vesicular Arbuscular Mycorrhizae (VAM) in meeting phosphorus needs of okra-wheat sequence in Typic hapludalf” was carried out in randomized block design with thirteen treatments replicated three times, during kharif 2005 & 2006 (okra as test crop)and rabi 2005-06 & 2006-07 (wheat as test crop) in the experimental Farm of Soil Science department,CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. Four level of P (0, 50, 75 and 100 % based on STCR approach) in combination with three different VAM culture viz; local (Glomus Sp.), TERI (Glomus introradices) and IARI (Glomus mosseae) were tested with okra and wheat in comparison with control. Soil samples taken from surface soil (0-15cm), after the harvests of okra as well as wheat during both the years of experimentation were analyzed for available NPK, DTPA extractable micronutrients (Fe, Cu, Zn and Mn) and soil pH using standard methods of analysis. Different forms of Phosphorus were also determined in the soil samples collected at the termination of entire experiment. Yield attributes, crop quality, root mass, root mass density, economic yield and nutrient uptake of okra as well as wheat increased significantly and consistently with increase in P application from 25 to 75 37 % of recommended P2O5 along with VAM culture and highest value was recorded with application of 100 % P2O5 as per STCR approach.. Higher value of VAM infection was recorded in treatment comprising 75 % P2O5 application as per STCR approach along with VAM culture. Significant improvement in the status of available NPK was recorded over the control. However, within certain treatments differences’ were not significant. In case of P, its status improved from initial value in treatment comprising 75 % and 100 % P2O5 application as per STCR approach. Phosphorus fractions varied in the order Fe-P > Al-P> Ca-P > saloid-P and these fractions have shown significant and positive correlation with available P, marketable fruit yield of okra, P uptake by okra crop, grain yield of wheat and P uptake by wheat crop. Comparable B:C ratios was recorded in treatments comprising 75 % P2O5 and 100 % P2O5 applied as per STCR based approach. From the findings of these experiments it may be concluded that in okra-wheat cropping sequence hill farmers can apply 75 % P2O5 as per STCR based approach along with Vesicular Arbuscular Mycorrhizal biofertilizer VAML (Glomus Sp.) (Rs. 20/- per kg) or VAMI (Glomus introradices) (Rs. 20/- per kg) in place of VAMT (Glomus mosseae) (Rs. 500/- per kg) as cost of this culture is high.
