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.

    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.

    IMPACT OF WEATHER PARAMETERS ON SEED PRODUCTION OF CAULIFLOWER (Brassica oleracea var. botrytis L.) IN MID HILLS OF HIMACHAL PRADESH
    (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.
