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 ORGANIC AND INORGANIC SOURCES OF NUTRIENTS ON SORGHUM SUDAN GRASS HYBRID - OAT CROPPING SYSTEM
    (CSKHPKV. Palampur, 2019-09) CHAHAL, ARVIND; Sharma, G.D.
    A field experiment entitled “Effect of organic and inorganic sources of nutrients on sorghum sudan grass hybrid-oat cropping system” was conducted at Research Farm of Department of Agronomy, Forages and Grassland Management, CSK, Himachal Pradesh Krishi Vishvavidyalaya, Palampur from Kharif 2017 to Rabi 2018-19. Soil of the experimental site was silty clay loam in texture, acidic in reaction, medium in organic carbon, available phosphorus and available potassium and low in available nitrogen. The experiment was laid out in a Randomized Block Design with two factors and replicated thrice. The treatments consisted of four levels of FYM and biofertilizers viz. control, FYM @10 t ha-1 , Azotobacter+ PSB and FYM @10 t ha-1 + Azotobacter + PSB and four levels of fertilizers viz. no fertilizer, 50, 75 and 100 per cent of recommended fertilizer. Significantly highest plant height, shoots per square meter and dry matter accumulation of sorghum sudan grass hybrid and oat was observed with application of FYM @10 t ha-1 + Azotobacter + PSB than rest of the organic treatments, though this treatment was at par with FYM @10 t ha-1 for leaf stem ratio. Similarly, plant height, shoots per square meter and dry matter accumulation increased with increasing fertilizer levels with highest values recorded with application of 100 per cent of recommended fertilizer though the increase in leaf stem ratio was significant only up to 75 per cent of recommended fertilizer. Significantly highest total green fodder, dry fodder, crude protein, acid detergent fibre and neutral detergent fibre yields and net returns were recorded with the application FYM @10 t ha1 + Azotobacter+ PSB as well as 100 per cent of recommended fertilizer. Application of FYM @10 t ha-1 + Azotobacter+ PSB resulted in higher benefit cost ratio, while, significantly highest benefit cost ratio was recorded with 100 per cent of recommended fertilizer. Crude protein content was significantly higher with application of FYM @10 t ha-1 + Azotobacter+ PSB as well as 100 per cent recommended fertilizer. However, the effect of FYM @10 t ha-1 + Azotobacter+ PSB and FYM @10 t ha-1 was same and resulted in significantly minimum content of acid detergent fibre and neutral detergent fibre. The effect of 75 and 100 per cent of recommended fertilizer was also same and resulted in significantly minimum acid detergent fibre and neutral detergent fibre content.An increase in soil organic carbon, biomass carbon and available NPK was observed with the application of FYM @10 t ha-1+Azotobacter + PSB as well as 100 per cent recommended fertilizer application over the initial status at the end of experiment
