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.

    Investigation and management of infertility in cows reared in tribal areas of Himachal Pradesh
    (Palampur, 2021-09-09) Sharma, Ankita; Singh, Madhumeet
    The present study was conducted on 664 cows affected with different forms of infertility and reared in tribal areas of Himachal Pradesh. Blood samples were collected from cows diagnosed reproductive abnormalities for minerals, hormones, biochemical estimation and DNA isolation and gene sequencing. In addition to that faecal and cervicovaginal discharge samples were collected to determine the endoparasitic load and in vitro antibiotic sensitivity of the cows, respectively. The objectives of current study were to document the infertility problems and evaluate the effect of various treatments for its management in cows of tribal areas of Himachal Pradesh. In present study, functional form of infertility had the highest prevalence in cows followed by infectious and anatomical causes. Forty seven per cent incidence of gastrointestinal infestation was recorded in faecal samples of cows. Among the different physiological and pathological conditions, anestrus cows had the highest incidence (22%) for parasitic load. After in vitro culture sensitivity test, fluoroquinolone group (Ciprofloxacin, Enrofloxacin, Ofloxacin and Levofloxacin) were recorded as the most sensitive antibiotics whereas metronidazole (91.2%) was most resistant. Also, blood plasma concentration of calcium in infertile cows of Kinnaur was significantly higher (p<0.01) as compared to other sampled tribal areas whereas the significantly higher (p<0.05) plasma concentration of phosphorus was recorded in Spiti region. Among the biochemicals, the blood plasma concentration of total protein was significantly lower (p<0.01) in infertile cows of Spiti region as compared to other sampled tribal areas. Overall 69.30 per cent cows conceived after treatment different reproductive ailments in infertility treatment camps. Following gene sequencing, the single nucleotide polymorphism was located 2175 bp upstream of the start codon of FOXP3 which could affect the fertility of cows and heifers.

    Effect of subsurface drip irrigation and drip line layering on soil water dynamics and productivity of tomato under protected environment
    (Palampur, 2021-09-22) Sharma, Ankita; Sandal, Sanjeev K.
    The present study was conducted at experimental farm of CSKHPKV, Palampur during the year 2020 with the objectives to evaluate the effect of subsurface drip irrigation and drip line layering on soil water dynamics, plant water content & water productivity, and to evaluate the effect of subsurface drip irrigation and drip line layering on nutrient uptake and crop productivity. The treatments comprised of two drip irrigation levels 0.4 PE (40 per cent of pan evaporation) and 0.8 PE (80 per cent of pan evaporation) with five subsurface layering viz., no layering, farm yard manure @ 10 t/ha, rice straw @ 10 t/ha, saw dust @ 10 t/ha, chopped weed biomass @ 10 t/ha. The tomato (Lycopersicum esculentum) crop was transplanted on May 4, 2020. The experimental results indicated that the soil water content and soil water stock was higher under 0.8 PE treatments which led to significantly higher plant height, relative leaf water content, marketable and straw yield as compared to 0.4 PE treatments. Among subsurface layering, plant height, marketable and straw yield, total NPK uptake were significantly higher under farm yard manure and lower under no layering. However, the root growth parameter was significantly higher under rice straw and lower under no layering. The gross return and B:C ratio were the highest under 0.8 PE + Farm yard manure and lowest under 0.4 PE + No layering treatment combination. The study concluded that the sub surface drip irrigation level of 0.8 PE and subsurface layering with Farm yard manure were the optimum treatment combination for obtaining maximum crop and water productivity

    GENETIC STUDIES FOR VARIOUS AGROMORPHOLOGICAL TRAITS AND DIVERSITY ANALYSIS USING IN SITU HYBRIDIZATION IN DIFFERENT OAT SPECIES
    (CSKHPKV, Palampur, 2019-04) Sharma, Ankita; Sood, Vinod Kumar
    The present investigation entitled, “Genetic studies for various agro-morphological traits and diversity analysis using in situ hybridization in different oat species” was undertaken to study the nature and magnitude of gene action for forage and seed yield contributing traits, to understand the inheritance of powdery mildew resistance and cytological analysis of different oat species so as to assess the diversity among them. Nine generations of six cross combinations namely, „HJ-8 x PLP-1, HJ-8 x EC-528896, HJ-8 x JPO-46, HJ-8 x Avena sterilis, HJ-8 x KRR-AK-26 and PLP-1 x A. sterilis‟ were evaluated in compact family block design with three replications during Rabi 2017-18. Simple scaling tests revealed the inadequacy of additive-dominance model for all the traits except leaves per plant and plant height indicating the presence of non-allelic interactions for these traits. Duplicate type of gene action was observed for two characters in cross HJ-8 x PLP-1, three in HJ-8 x EC-528896, ten in HJ-8 x JPO-46, five in HJ-8 x A. sterilis, seven in HJ-8 x KRRAK- 26 and for four characters in PLP-1 x A. sterilis. Complementary type of epistasis was observed for one character in HJ-8 x A. sterilis and two characters in HJ-8 x KRR-AK-26. The best heterotic crosses coupled with low inbreeding depression were HJ-8 x PLP-1 for dry matter yield and crude protein yield per plant; HJ-8 x EC-528896 for fresh fodder yield and biological yield per plant; HJ-8 x JPO-46 for seed yield per plant and HJ-8 x KRR-AK-26 for days to 50% flowering & days to 75% maturity. The outcome of the present endeavour suggested that HJ-8 x JPO-46 and HJ-8 x EC-528896 crosses may be exploited through biparental approach in early generations followed by recurrent selection in later generations for harnessing desirable transgressive segregants. The segregation pattern of powdery mildew disease indicated that resistance was governed by a single dominant gene in HJ-8 x PLP-1, HJ-8 x EC-528896, HJ-8 x JPO-46, HJ-8 x A. sterilis and HJ-8 x KRR-AK-26 cross combinations. While comparing the karyotype of different Avena species, it was observed that in tetraploid (A. barbata and A. murphii) and hexaploid species (A. sterilis and A.sativa) the number of sat chromosomes and subterminal chromosomes were just the same as that in the diploids (A. strigosa).Thus indicated that some chromosomes of A.strigosa may be present in these tetra and hexaploid species. The most striking feature of the hexaploid karyotype was 10 subterminal chromosomes while in diploid and tetraploid species only two subterminal chromosomes were present thus indicating the unknown sources of different genomes.
