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 phosphorus, boron and lime on maize productivity and soil properties in an acid Alfisol
    (CSK HPKV, Palampur, 2022-12-29) Anshudha; Sharma, Sanjay K.
    A field experiment was carried out during kharif 2021 on maize (Zea mays L.) at the experimental farm of the Department of Soil Science, COA, CSKHPKV, Palampur. The experiment comprised eighteen treatments with three levels of phosphorus (0, 75 and 100% of recommended P2O5 ha -1 ), 3 levels of boron (0, 1.0 and 2.0 kg B ha-1 ) and two levels of lime (0 and lime @100% of lime requirement), replicated thrice in a randomized block design to evaluate the effect of phosphorus, boron and lime application on maize productivity and soil properties in an acid Alfisol. Application of 60 kg P2O5 ha-1 , 2.0 kg B ha-1 as well as application of lime registered better growth and yield attributes. The interactions (P × L, B × L, P × B) were significant only in the case of plant height and were not found significant on the number of cobs plant-1 , the number of rows cob-1 , cob length and test weight. Application of 60 kg P2O5 ha-1 recorded significantly higher grain (49.1 q ha-1 ) and stover yield (65.7 q ha-1 ). Similarly, the application of 2.0 kg B ha-1 recorded significantly higher grain and stover yields (47.9 and 65.5 q ha-1 , respectively). Lime application also resulted in a significant increase in both grain and stover yields (13.4 and 18.7%, respectively) over control. Nutrient uptake (N, P, K and B) by maize, protein content and protein yield were enhanced with the application of 60 kg P2O5 ha-1 , 2.0 kg B ha-1 and liming. A marked increase in soil pH was observed only with the lime application. Soil organic carbon was not affected significantly by applying varying P and B levels as well as liming. Available N, P and B were significantly higher with the application of 60 kg P2O5 ha-1 , 2.0 kg B ha-1 and lime application. However, available K was not affected significantly by the application of phosphorus and boron whereas, liming increased the available K content of soil. Microbiological properties viz., microbial count of bacteria, fungi and actinomycetes, microbial biomass carbon, microbial biomass nitrogen also improved with the application of 60 kg P2O5 ha-1 , 2.0 kg B ha-1 and lime application except for fungal count which decreased with the lime application and soil urease activity, which recorded no significant change with B application. Despite, the highest cost of cultivation, application of 60 kg P2O5 ha-1 and B @ 2.0 kg ha-1 along with lime has been found to be most remunerative in terms of gross and net returns, though the benefit-cost ratio was comparatively lower owing to the higher cost involved in liming. But expecting the residual effects of liming on succeeding crops, the application of 60 kg P2O5 ha-1 and B @ 2.0 kg ha-1 and liming @ 100% LR may be considered ideal for realizing higher yield and net returns.
