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.)

    STUDIES ON EFFECT OF INTERCROPPING, MULCHING AND MANURIAL PRACTICES ON YIELD AND QUALITY OF TURMERIC (Curcuma longa L.)
    (UHF Nauni, 2024-04-18) MEENAKSHI; H Dev Sharma
    The present investigation entitled “Studies on effect of intercropping, mulching and manurial practices on yield and quality of turmeric (Curcuma longa L.)” was conducted during Kharif season of 2021-22 and 2022-23 at research farm and laboratory of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Turmeric was intercropped with two different intercrops viz., maize and okra with polythene and grass mulch along with one of the three manurial practices viz., 200 q/ha FYM, 200 q/ha FYM + Beejamrit + Ghanjeevamrit + Jeevamrit and 200 q/ha FYM + RDF (30 kg N/ha + 30 kg P2O5/ha + 60 kg K2O/ha) which were replicated thrice in the form of twelve treatments and one sole turmeric crop treatment in a plot size of 3×1 m. The experiment was laid out in a randomized complete block design (RCBD) involving a spacing of 30×20 cm for main crop, 60×20 cm for intercrops. Sowing and planting of both main crop and intercrops was done in the month of June. The parameters observed were plant height (cm), tiller girth (cm), number of tillers per plant, number of leaves per plant, leaf length (cm), leaf width (cm), leaf area index (LAI), incidence of rhizome rot (%) if any, yield of main crop and intercrops per plant (g), rhizome length (cm), rhizome breadth (cm), number of primary rhizomes, number of secondary rhizomes, specific gravity (g/cc), dry rhizome recovery (%), essential oil (%), oleoresin content (%), total curcuminoid content (%), pH, EC (dSm-1), OC (%), NPK content of soil before and after termination of experiment (kg ha-1) and microbial count in soil (cfu/g). The benefit cost ratio and land use efficiency was also worked out. From the present investigation, it can be concluded that turmeric cv. Palam Lalima intercropped with okra cv. P-8 along with polythene mulch with the application of RDF (30 kg N/ha + 30 kg P2O5/ha + 60 kg K2O/ha) gave the turmeric rhizome yield 252.86 q/ha and okra yield 79.75 q/ha, maximum net returns of ₹ 956419 and benefit cost ratio of 2.56 followed by turmeric cv. Palam Lalima intercropped with okra cv. P-8 along with polythene mulch with the application of Beejamrit, Ghanjeevamrit and Jeevamrit which gave turmeric rhizome yield of 245.08 q/ha and okra yield 77.78 q/ha, net return of ₹ 916550 and benefit cost ratio of 2.44, under mid hill conditions of Himachal Pradesh.

    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-12-02) MEENAKSHI; KUMAR, SUNIL
    The present investigations entitled “Biology and Management of Diamondback moth, Plutella xylostella on crucifers” was carried out in the Department of Entomology, College of Horticulture and Forestry, Neri (Hamirpur), Himachal Pradesh. Experiments were conducted to understand and collect data on selected aspects of diamondback moth (DBM), Plutella xylostella like study of biology of DBM i.e. studied on four hosts of crucifer crops. Among these cauliflower and cabbage showed short life cycle as compared to radish and mustard. The total life cycle was completed faster in cauliflower (21.40 days) and in cabbage (25.20 days). Egg hatched (out of 100 eggs) was highest in mustard (98.00) followed by cauliflower (97.80). In bio-efficacy studies of different leaf extracts and agniastra against DBM indicated that overall mean per cent larval and pupal mortality were 46.44 and 80.67, respectively at 2.0% concentration of agniastra and minimum per cent larval and pupal mortality were 14.55 and 48.89 were recorded in aqueous leaf extract of bhang at 5.0%. From the result we can conclude that agniastra was the best formulation for the management of DBM in crucifer crops when the formulation applied at larval stages. The maximum per cent antifeedant activities were shown by 2.0% agniastra (83.56) followed by 10% aqueous leaf extract of eupatorium (67.99) higher than the standard check (chloropyriphos @ 0.01%). Bioefficacy studies of different aqueous seed extracts and cow urine against DBM, indicated that over all mean per cent larval and pupal mortality were achieved at 10% aqueous NSKE were 78.10 and 83.89, respectively. In repellent effect, NSKE have maximum per cent repellent rate 84.63 at 10% concentration and minimum 38.93 at 2.0% concentration of cow urine.

    STUDIES ON IMPROVEMENT OF SYMBIOTIC NITROGEN FIXATION IN Albizia procera (Roxb.) Benth. UNDER MID HIMALAYAN REGION
    (UHF,NAUNI, 2019-11) MEENAKSHI; RANA, NEERJA
    ABSTRACT The intensive harvesting of forest resources have led to decreased nitrogen and organic matter content in the forest soils. Biological nitrogen fixation (BNF) is a cheap renewable nitrogen source, essential to the sustainable productivity of afforested sites. Biological nitrogen fixation offers economically and ecologically sound means for reducing the requirement of nitrogenous fertilizer, thereby restoring the degraded ecosystem. The present investigation entitled “Studies on improvement of symbiotic nitrogen fixation in Albizia procera (Roxb.) Benth. under mid Himalayan region” was carried out in the Microbiology Laboratory of Department of Basic Sciences during the years 2016-2019. Results of the study revealed that among the 10 different seed sources, Baddi seed source of Himachal Pradesh and FRI seed source from Uttrakhand were found best for pod, seed germination and seedling growth parameters. It is evident from the studies that larger seeds have greater per cent germination than smaller seeds. Non significant variation between pod and seed traits with geographical factors were noticed which indicated non-clinal variation. In total of 66 isolates, 38 from Himachal Pradesh and 28 from Uttrakhand were isolated fromroot nodules of Albizia procera seedlings. On the basis of authentication tests only 38 isolates were confirmed as rhizobia. Among these 38 rhizobial isolates, 29 isolates were Psolubilizers, 27 isolates were siderophore producers and 19 isolates were HCN producers. Among the 21 rhizobial isolates from Himachal Pradesh maximum P-solubilization (263.23µg/ml), siderophore production (106.30%) and IAA (82.75µg/ml) was recorded with rhizobial isolate BA2. Whereas, maximum P-solubilization (261.00µg/ml), siderophore production (108.12%) and IAA (85.52µg/ml) was recorded with rhizobial isolate FA6 from Uttrakhand. Rhizobial isolates BA2 and FA6 also showed high per cent growth inhibition against 6 fungal pathogens. On the basis of plant growth promoting traits and antifungal activities, two isolates BA2 and FA6 were selected and applied as biofertilizers. Both the biofertilizers with 20kg/ha nitrogen significantly increased shoot biomass, root biomass, nodulation status and available N P K content of soil over uninoculated control. These isolates were identified as Rhizobium leguminosarum (BA2) and Rhizobium alamii (FA6). The application of charcoal based bio-inoculant of rhizobial strain FA6+20 kg/ha nitrogen has not only significantly influenced growth characters and nitrogen fixation potential of Albizia procera seedlings but also improved the available N P K content of the soil. Hence, application of charcoal based bioinoculant with rhizobial strain FA6 have enormous potential to be used as biofertilizer for enhanced growth, nodulation status and protection of A.procera seedlings and to sustain soil health.

    BIOCOLOR PRODUCTION FROM BACTERIA INHABITING HOT WATER SPRINGS OF HIMACHAL PRADESH
    (2015) MEENAKSHI; RANA, NIRJA
    ABSTRACT Colors are one of the significant visual properties and are important attribute of any article. Many artificial food colors usually used in foodstuff, dyestuff, cosmetics and pharmaceuticals pose various hazardous effects which may cause damage to the vital organs. Natural colors are generally extracted from fruits, vegetables, roots and microorganisms and are often called as biocolor. Microorganisms serve as a potential source for natural colors. The present investigations entitled “Biocolor production from bacteria inhabiting hot water springs of Himachal Pradesh” was carried in the Deaprtment of Basic Sciences, Dr Y.S. Parmar University of Horticulture and Forestry Nauni - Solan (HP) during the years 2013- 2015. The study was carried out to isolate the pigment producing bacteria from different hot water springs of Himachal Pradesh. Subsequently, their screening and characterization was done on the basis of morphological, biochemical and molecular parameters. Out of 44 bacterial isolates 3 bacterial isolates viz., M1, V1 and MS2 were identified as yellow color producing Micrococcus sp, pink colour producing Miccrococcus sp. (roseus) and orange red color producing Sarcina sp. respectively. The higher yields of biocolors from these three isolates was obtained in LB medium after 72 hrs of incubation at pH 7.0 and 40 o C temperature. Among different carbon sources glucose (0.5%) M1 and maltose (0.5% and 1%) V1 and MS2 were found to be the best. Among different nitrogen sources, peptone (0.5%) for M1, urea (0.1% ) for V1 and potassium nitrate (0.5%) for MS2 were found to be the most suitable for maximum pigment production. Thin layer chromatography of the pigments showed the presence of 2 spots for each pigment. The yellow pigment of M1 showed Rf values of two spots were 0.90 and 0.91 typical to that of -carotene. The two spot of orange pigment of MS2 isolate gave the Rf values 0.80 and 0.83 which was identified as prodigiosin. The third isolate producing peach colored pigment exhibited Rf values of 0.75 and 0.18 which were identified as tourulene and torularhodin. The bacterial isolates namely, M1(yellow) and MS2 (orange red) yielded stable colors out of 3 selected bacterial isolates. These two bioclors can be used for dyeing of cotton fabrics with thiourea as mordant. Thus, potential of biocolor from bacteria inhabiting hot water springs of Himachal Pradesh can be exploited in dyeing industrie
