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 BIOACTIVE METABOLITES PRODUCING STRAINS OF Pseudomonas SPECIES FOR SURVIVAL AND GROWTH PROMOTION OF REPLANTED APPLE
    (2016) KAUNDAL, KIRTI; KAUR, MOHINDER
    ABSTRACT The present study focuses on characterization of secondary antifungal metabolites i.e. Phenazine and Pyrrolnitrin produced by fluorescent Pseudomonas sp. isolated from the normal and replant sites of Maggota and Sioa of apple orchards. Twelve strains were isolated from the replant sites of Maggota and Siao of Shimla distt. and four already isolated strains of fluorescent Pseudomonas sp. from replant sites of apple were screened out for direct and indirect plant growth promoting activities like antifungal, siderophores, phosphate solubilization and production of HCN, ammonia, plant growth regulators (auxins, cytokinins and gibberellins) and lytic enzymes. By 16S Rrna gene characterization isolates An-3-Mg and An-19-Mg showed 99% similarity with Pseudomonas poae and Pseudomonasputida respectively. Three fungal isolates from replant site of orchard at Maggota showed similarity i.e. ARF1 (Fusarium oxysporum, 99%), ARF2 (Acremonium zeae, 97%) and ARF3 (Curvularia australiensis, 99%) and one isolate from replant site of orchard at Siao i.e. ARF4 99% similarity with Plectosphaerella cucumerina by ITS gene sequencing method. Optimization of media, time of incubation, temperature, pH, carbon and mineral sources were done for production and extraction of antifungal metabolites i.e. Phenazine & Pyrrolnitrin and for mass multiplication of inoculums for field trials. These metabolites were extracted with benzene and acetone identified and characterized through TLC at Rf 0.52 and 0.25 respectively. Antifungal activity, MIC and thermal stability of both these metabolites were evaluated. Phenazine was further characterized through HPLC, NMR and FTIR techniques. The extracted metabolite showed inhibition of fungal pathogens i.e. 24.2 to 44.2%. Individual and consortial formulation of four best selected strains i.e. P. putida (L), P.fluorescens(M) and P.aeruginosa (G and H) showed growth promotion in terms of plant height, no. of nodes, Chl content, available NPK and available micronutrients of replanted apple at Maggota and Siao. Therefore these strains can be exploited for the management of replant problem of apple. Signature

    EFFECT OF SELECTED PLANT GROWTH PROMOTING RHIZOBACTERIA ON GROWTH AND YIELD OF GINGER (Zingiber officinale Rosc.)
    (2012) KAUNDAL, KIRTI; KAUSHAL, RAJESH
    ABSTRACT Ginger being heavy feeder and exhaustive crop requires large quantities of nutrient elements. Chemical fertilizers besides being costly and also causes degradations both to soil and environment. The nutrient requirements and changing climatic conditions coupled with higher incidence of diseases such as soft rot (Pythium spp.) and Fusarium wilt (Fusarium spp.) and pests infestation resulted in sizeable yields loss in mid hills of Himachal Pradesh. The use of PGPR to supplement chemical fertilizers and pesticides is a potential alternative but no commercial formulation is available for the crop. So, the present investigations entitled “Effect of selected plant growth promoting rhizobacteria on growth and yield of ginger (Zingiber officinale Rosc.)” were carried out during 2009-2011. Rhizosphere and root samples of ginger were collected from major ginger growing area by selecting four locations i.e. Nauni, Kandaghat and Narag, Rajgarh in Solan and Sirmour districts of Himachal Pradesh. A total of 32 isolates were isolated by using modified replica plate method. On the basis of colony morphological similarities seven isolates were selected for screening of possession of multifarious plant growth promoting traits. Among which KK5 isolate possesses maximum plant growth promoting attributes like P-solubilization (86.6%) on PVK solid medium, (202.2 μg/ml) in broth, growth on Jensen’s medium, siderophore production (86.7%), auxin production (29.6 μg/ml), HCN production and antagonism against Pythium spp. (43.2%) and Fusarium spp. (42.5%). On the basis of morphological (Gram +ve rods), physiological (optimum growth at 35 ° C and 7 pH) and biochemical characteristics (Glucose fermentation, production of gelatinase and catalase enzymes) KK5 isolate tentaviley identified as Bacillus spp. Rhizome bacterization with KK5 isolate not only showed significant increase in plant parameters such as shoot length (47.6 % and 38.0%), number of tillers (46.9% and 48.9%), number of leaves (43.1% and 39.7%) and yields (48.3 % and 43.5 %) over C1 (uninoculated absolute control) and C2 (uninoculated fungicide control) treatments, respectively but also increased available N, P and K by 26.5 per cent, 22.9 per cent and 18.8 per cent, respectively over initial contents. On the basis of efficacy i.e. rhizocompetence and plant growth promoting efficiency under net house studies the bacterial isolate KK5 has good potential to be used as biofertilizer or biocontrol agent for ginger production in mid hills conditions of Himachal Pradesh.
