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.

    ABSTRACT Carnation (Dianthus caryophyllus L.) belongs to family Caryophyllaceae and is native of the Mediterranean region. It is one of the most popular and commercially important cut flower. The commercial production of carnation is due to its excellent keeping quality, broad range of colors, shapes, size and fragrance, potential to withstand long distance transportation. Presently, in order to obtain excellent quality of cut flower throughout the year, nutrients viz., N P K are supplied through chemical fertilizer. Excessive and indiscriminate use of these chemical fertilizers not only affects soil health and environment but also pose extra debt on farmer’s pocket. Therefore, there is a need to standardize the optimum dose of nutrition by balancing organic and inorganic fertilizers which proves out to be good for soil health and environment. So, the present investigations were undertaken to isolate potential endophytic bacterial isolates from roots of carnation plants and their characterization for efficient plant growth promoting traits. A total of 97 endophytic bacteria were isolated from the root samples of carnation. Out of 97 isolates, 52 isolates were P- solubilizers and siderophore producers and 50 were IAA producers. Finally, from the total only two best endophytic bacterial isolates SR-1 and NH-3 were selected for polyhouse trial, on the basis of P-solubilization, siderophore production, IAA production , growth on nitrogen free media, antagonism against Fusarium oxysporium and Rhizoctonia solani, HCN production and lytic enzyme production and hence characterized morpho-biochemically and by 16S rDNA sequencing. The application of 75% NP +SR-1 and 75% NP + NH-3 not only registered the tremendous increase in all plant parameters but also increased the available NPK in soil. Thus, the endophytic bacterial isolates have enormous potential to act as a multifunctional biofertilizers, biostimulant and bioprotectant for carnation.

    (UHF,NAUNI, 2019-08) SHARMA, PRIYANKA; VERMA, S C
    ABSTARCT The present investigations entitled “Studies on spatial distribution and parasitisation potential of Aphelinus asychis Walker against green peach aphid, Myzus persicae (Sulzer) in Bell pepper” were conductedduring the year 2018-2019 at Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. During the study period, M. persicae and its parasitoid, A. asychis and A.matricariae populations followed negative binomial distribution throughout the season. Taylor’s power equation for M. persicae, A. asychis and A.matricariae were σ² = 6.97X1.531 (R2 = 0.931), σ² = 3.013X1.098 (R2 = 0.867) and σ² = 4.29X1.282 (R2 = 0.90) during 2018-2019, respectively. Iwao’s patchiness regression was X* = 45.12 + 1.333X (R2 = 0.853), X* = 1.485 + 1.375X (R2 =0.784) and X* = 5.406 + 1.195X (R2 =0.767) during 2018-2019, respectively. Optimum number of samples required for the green peach aphid, M. persicae, A. asychis and A.matricariae were 261.1, 332.5 and 474 during 2018-2019, respectively at 20 per cent precision level. The egg to adult emergence period, pre-oviposition period, oviposition period, post-oviposition period, fecundity, sex ratio (F:M) was 16.23±0.45, 1±0.00, 6.6±0.40, 1.6±0.40 days, 58.8 eggs/female, 1:0.97, respectively. The highest adult longeivity (male:16.5 and female:17.75 days) was observed with 70 per cent honey solution sand lowest with distilled water (male:8.75 and female:9.75 days). The true generation time (T), the true intrinsic rate of increase (rm), doubling time, finite rate of increase (λ) and the net reproductive rate of the parasitoid, A. asychis with second instar of M. persicae was 22.02 days, 0.16 females/female/day, 2.52 days, 1.174 feamles/day and 33.32 feamles/feamle, respectively. A. asychis parasitized 20.29 per cent during 2018-2019. A hyperparasitoid, Alloxysta victrix parasitizing A. asychis between 20.00 to 27.27 per cent was recorded during 2018-2019. A. asychis was able to parasitize all the nymphal instars of M. persicae with preference to the second instar (53%) followed by first instar (46%), third instar (44%) and fourth instar (33%). A. asychis exhibited a Type-II functional response to the second instar nymph of M. persicae with attack rate and handling time was 0.034 ± 0.004 h-1 and 1.32 ± 0.23 h, respectively for the Holling disc equation. Hence, A. asychis can be utilized as one of the components in the integrated pest management programme of green peach aphid, under protected condition in Himachal Pradesh.

    (UHF, NAUNI, 2018-10) SHARMA, PRIYANKA; GUPTA, Y C
    ABSTRACT The present investigation entitled, “Studies on the effect of plant spacing and shoot thinning on Godetia grandiflora (Lindl.)” was carried out at the Research Farm of the Department of Floriculture and Landscape Architecture, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) from October 2017 to June 2018. Objective of the research was to find out the effects of plant spacing and shoot thinning for cut flower production of Godetia. The experiment was laid out in randomized block design (Factorial) with four treatment combinations replicated thrice.The observations on various growth ands flowering parameterwere recorded. Results revealed that Among three different spacing viz., 30×20 cm, 30×25 cm and 30×30 cm, plant spacing (30×25 cm) gave best result for parameters like plant height (79.89 cm), stem length of secondary branches (56.38 cm), number of cut stem per plant(9.95) and vase life (10.43 days) whereas maximum plant spread (50.71 cm), number of flowers per stem (8.17), size of flower (4.17) was recorded with spacing of 30×30 cm and yield of cut stems per plot (248.73) was recorded with spacing of 30×20 cm. Among four different shoot thinning viz., T1(no shoot thinning), T2 (4 healthy shoots retained and others thinned out), T3 (5 healthy shoots retained and others thinned out) and T4(6 healthy shoots retained and others thinned out), shoot thinning T2 with 4 healthy shoots retained and others thinned out gave best result for parameter like plant height (77.22 cm), plant spread (52.32 cm), stem length of secondary branches (54.27 cm), whereas maximum number of flowers per stem (8.11), number of cut stem per plant(11.27), size of flower (3.99 cm),vase life (9.15 days) and yield of cut stems per plot (248.73) was recorded with 5 healthy shoots retained and others thinned out. The maximum yield of cut stem per plot was found in spacing 30 × 20 cm which was found to be at par with 30 × 25 cm and shoot thinning (T3) with 5 healthy shoots retained gave more production per unit area.

    IMPACT OF WEATHER AND ORCHARD MANAGEMENT PRACTICES ON APPLE PRODUCTIVITY AND SOIL HEALTH IN KULLU DISTRICT OF HIMACHAL PRADESH
    (UHF,NAUNI, 2017-12) SHARMA, PRIYANKA; MOHINDER, SINGH
    ABSTRACT The present investigation entitled “Impact of weather and orchard management practices on apple productivity and soil health in Kullu district of Himachal Pradesh” was conducted during the years 2015 and 2016 at four altitudinal gradients/locations, viz. Bajaura (1090m amsl), Seobagh (1189m amsl), Naggar (1880m amsl) and Arsu (2080 m amsl), on three commercial apple varieties viz. Red Delicious, Royal Delicious and Golden Delicious. The different phenological stages (Silver tip, Green tip, Pink bud, Full bloom and Petal fall) in apple were observed at earliest at Bajaura, where the apple crop experienced higher average temperature compared to other locations. Minimum number of days for silver tip stage (54.22 days with 349.22 GDD), green tip stage (71.67 days with 484.00 GDD), pink bud stage (86.94 days with 662.54 GDD), full bloom stage (93.89 days with 749.67 GDD) and for petal fall stage (99.00 days with 807.48 GDD) were observed at Bajaura, followed by Seobagh, Naggar and Arsu. Among different cultivars, Red Delicious cultivar took minimum number of days for silver tip stage (56.58 days and 264.93 GDD), green tip stage (74.92 days with 387.44 GDD), pink bud stage (89.00 days with 526.85 GDD), full bloom stage (95.71 days with 598.33 GDD) and for petal fall stage (101.58 days with 662.14 GDD), followed by Royal Delicious and Golden Delicious. The studies on long term impact of weather parameters on apple productivity revealed that the minimum temperature during dormancy stage (Jan- March) exhibited positive and significant correlation with productivity of apple. Whereas, maximum temperature during April- June (flowering, fruit set and fruit development stage) showed negative and significant impact on apple productivity. The studies on effect of management practices and orchard aspect on soil health at different locations revealed maximum soil pH (6.77) and OC (2.92 %) in low input orchards when compared with high input orchards. Among different locations highest soil pH and EC were found in Arsu, followed by Naggar, Seobagh and Bajaura. High input orchards showed higher values of soil macronutrients, N (330.4 kg/ha), P (36.64 kg/ha) and K (287.4 kg/ha) than low input orchards. Soil micronutrients Fe, Zn and Cu were also found higher in high input orchards. In low input orchards, soil microbial count and biomass were recorded higher than high input orchards. The orchards in south west aspect recorded higher N (309.7 kg/ha) and Mn (27.60 mg/kg) as compared to orchards in north east aspect. Whereas, other soil parameters were found higher in north east than south west aspect.

    (UHF,NAUNI, 2017-11) SHARMA, PRIYANKA; MOHINDER, SINGH
    ABSTRACT The present study entitled “Impact of weather parameters on seed production of cauliflower (Brassica oleracea var. botrytis L.) in mid hills of Himachal Pradesh” was conducted at three locations viz; Nauni, Saproon and Kandaghat during rabi season of 2014-2015 and 2015-2016 in Solan district of Himachal Pradesh. The location Nauni was warmest, followed by Kandaghat and Saproon. Significant variations in seed yield and yield contributing characters of cauliflower were observed due to execution of different weather conditions. The minimum number of days to flower initiation, 50 per cent flowering, initiation of seed stalk and seed set in cauliflower were observed at Nauni, followed by Kandaghat and Saproon. Number of pods per plant and number of seeds per pod were found highest at Saproon (1055.2pods/plant; 18.4seeds/pod) which is coolest location as compared to other two. The maximum seed yield (239.6 kg/ha) was obtained from this location. Nauni and Kandaghat showed reduced cauliflower seed yield compared to that obtained from Saproon. The lowest seed yield (174.0 kg/ha) was recorded at Nauni. The forenoon humidity during October to December exhibited significant and positive correlation with seed yield. During January to March minimum temperature showed significant and positive correlation with seed yield, whereas during April to June maximum temperature showed significant and positive impact on cauliflower seed production. Four classes of pollinators; honey bees, syrphid flies, other wild bees and other insect pollinators (butterflies, moths and beetles etc.) were recorded on cauliflower seed crop in three study locations. Weather parameters mainly minimum temperature and forenoon humidity influenced the foraging activity of different pollinators. Among different pollinators honey bees were most frequent visitors. The pollinator abundance was highest at Saproon followed by Kandaghat and Nauni. The cabbage aphid, cabbage caterpillar and painted bug were recorded important insect pests on cauliflower seed crop. Highest pest infestation was recorded at Nauni, followed by Kandaghat and lowest at Saproon.
