Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    CHARACTERIZATION OF Frankia spp. ASSOCIATED WITH NON-LEGUMINOUS NITROGEN-FIXING PLANTS OF WESTERN HIMALAYA
    (UHF,NAUNI, 2018-03) BHARDWAJ, SONAL; KAUSHAL, RAJESH
    ABSTRACT In recent years, land degradation has increased considerably due to demographic pressure and climatic factors which has resulted in reduction of biodiversity, soil fertility and crop productivity. To overcome the problems of lack of soil fertility in degraded areas, fast growing nitrogen fixing actinorhizal plants are being considered for plantation programme. The studies on actinorhizal associations with prominent non-leguminous species of mid and high hills i.e. Casuarina equisetifolia and Alnus nitida were conducted during 2014-2017. The studies revealed that Casuarina samples harboured more actinobacterial population in root nodules compared to Alnus. Among different media tried, Defined Propionate Minimal (DPM) medium with pyruvate as carbon source was most suitable for the growth of actinobacteria. A total of 33 isolates from both the species were isolated from Solan (mid hills) and Kullu (high hills) districts of Himachal Pradesh. Out of these 33 isolates, only 10 isolates exhibited maximum plant growth promoting traits viz. phosphate solubilization (250.0- 379.2 μg/ml), HCN production, growth on nitrogen free medium, auxin production (15.2-59.1 μg/ml) and siderophore production (44.2-90.2% siderophore unit) as well as antagonism against Fusarium oxysporum, Pythium sp., Rhizoctonia solani and Phytophthora sp. The phenotypic characterization of the isolates showing branched hyphae bearing sporangia, vesicle like structures, non-turbidity of liquid medium and formation of nodules in plant infection tests confirmed their identity with Frankia. The molecular characterization of Inter Transcribed Spacer (ITS) region with selected primers was successful for three isolates (ANG10, ANG11 and CG1). It revealed the similarity of two isolates i.e. ANG10 and ANG11 with Micromonospora sp. (88% and 90%, respectively) and in 23S region with Frankia sp. (91% and 91%, respectively). The ITS region of CG1 isolate showed similarity with Verrucosispora sp. (98%) and in 23S region with Frankia sp. (93%). The sequence similarity was less with Frankia sp., which necessitates the identification of these isolates to be verified with whole genome sequencing. The effect of application of selected isolates on plant growth and soil parameters indicated that inoculation with CG1 isolate for Casuarina equisetifolia and ANG11 isolate for Alnus nitida led to significant increase in shoot-root length, total biomass, total NPK content and their uptake and available NPK content in soil over uninoculated control. Hence, these isolates have enormous potential to be used as multifunctional biofertilizer for enhanced growth of actinorhizal plants and to sustain soil health under mid and high hills of Himachal Pradesh.

    INTEGRATED NUTRIENT MODULE FOR ENHANCED PRODUCTIVITY OF CAULIFLOWER UNDER LOW AND MID HILLS OF HIMACHAL PRADESH
    (2013) BHARDWAJ, SONAL; KAUSHAL, RAJESH
    ABSTRACT Our whole system of agriculture depends on microbial activities and there appears to be a tremendous potential for making use of these microorganisms in increasing crop production. The beneficial rhizospheric microorganisms are designated as plant growth promoting rhizobacteria, act as biofertilizers, bioprotectants and biostimulants. These PGPR exert their growth promoting effects by a number of direct and indirect mechanisms. Therefore, present studies were undertaken to isolate and screen bacterial isolates from rhizosphere/endorhizosphere of cauliflower from Una district (Lalsingi, Ghaluwal, Bhadsali and Basal locations) of Himachal Pradesh to develop an effective inoculum of PGPR with multifarious plant-growth promoting traits (P-solubilization, N-fixation, IAA, Siderophore, HCN production and antagonism against soil borne pathogens). Out of the selected 25 isolates, only four isolates (SB5, SB8, SB10 and SB11) exhibited maximum plant growth promoting traits. On the basis of morphological (Gram +ve rods), physiological (optimum growth at 35oC and 7 pH) and biochemical characteristics (casein hydrolysis, production of gelatinase and catalase enzymes) these four isolates were tentatively identified as Bacillus sp. A reference isolate MK5 identified as Bacillus pumilus was procured from the Soil Microbiology Laboratory and used along with the selected four isolates for present studies. Out of these five isolates, MK5 and SB11 isolates have maximum plant growth promoting traits and also effective to control stalk rot, root rot and damping off diseases of cauliflower. The application of PGPR isolate (MK5) alongwith 75 per cent NP (N94 and P57 kg/ha) registered a significant increase in curd yield by 34 per cent (average of all the locations), increased available N and P content by an average of 32 and 42 per cent , respectively, however, it was statistically at par with SB11 + 75 per cent levels of NP (N94 and P57 kg/ha).Thus, the conjoint application of PGPR isolates at 75 per cent recommended levels of N & P not only registered an increase in yield but also saved 25 per cent NP (31 kg N/ha and 19 kg P/ha) chemical fertilizers. Hence, the developed technology has good prospects to be used not only for enhanced curd production but also to sustain soil health under low and mid hill conditions of Himachal Pradesh.
