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.

    “Studies on the effect of Dormex and CPPU on biochemical changes and production of kiwifruit (Actinidia deliciosa Chev.)”
    (UHF,NAUNI, 2017) BABITA; RANA, VISHAL S.
    ABSTRACT The present investigation entitled “Studies on the effect of Dormex and CPPU on biochemical changes and production of kiwifruit (Actinidia deliciosa Chev.)” was carried out in the Kiwifruit Block of Department of Fruit Science during 2014-16. The kiwifruit vines having uniform growth and vigour, planted at a spacing of 4m x 6m and trained on T- bar system were selected for the present study. The entire program of study was divided into three experiments. The Experiment-I was laid out according to RBD 12-years-old kiwifruit cv. Hayward and comprised of seven treatments viz., T 1 (Dormex 2%), T 2 (DORMEX 2% + Mineral oil (Orchol) 2%), T 3 (Dormex 4%), T 4 (Dormex 4 % + Mineral oil (Orchol) 2%), T 5 (Dormex at 6%), T 6 (Dormex Mineral oil (Orchol) 2%) and T 7 (control). These treatments were given 45 days prior to anticipated date of bud break as a foliar spray. Application of Dormex at 4 per cent along with mineral oil 2 per cent resulted an advancement of bud break by 9-10 days, emergence of flower buds by 9 days, full bloom date by 9-11 days, fruit set by 11-12 days. Maximum number of shoots emergence and number of buds per flowering shoots were also obtained with this treatment in comparison to control. Further, this treatment resulted in highest total fruit yield, maximum periodic increase in bud peroxidase activity with the concurrent decrease in catalase activity and highest C/N ratio in comparison to untreated vines. The Experiment-II was laid out according to Variance-ratio test (F-test) and Fisher’s t-test/ Behran dtest on 30-years-old vines of Allison kiwifruit, comprising CPPU (a synthetic cytokinin) treated and untreated fruits to study the different growth kinetic curves in developing kiwifruit. The CPPU 5ppm was applied as a fruit dip treatment after 10 days of petal fall. The results revealed that CPPU treated fruit exhibited higher fresh weight at 15 days interval exhibited double sigmoid growth pattern, characterized by rapid growth for 75days (Stage-I), period slow growth for 15 days (Stage-II) and period of enhanced growth for 90 days (Stage-III). This treatment also resulted in bigger sized fruits in terms of length and diameter. The CPPU treated fruits recorded higher amounts of total carbohydrates, ascorbic acid, organic acids and nutrients viz., nitrogen, phosphorus, potassium, calcium and magnesium. Among growth hormones, CPPU exhibited higher levels of IAA, GA 3 , Zeatin riboside with lower levels of ABA during all fruit growth stages. Residue dynamics of CPPU in kiwifruit revealed a rapid and continuous decrease of CPPU residues in developing kiwifruit with complete dessipation after 45 days of application. The Experiment-III was carried out to illucidate the effect of CPPU on the postharvest behaviour of kiwifruit after storage at ambient temperature (25+2 o C). This experiment was laid out according to RBD factorial. During storage, CPPU treated fruits exhibited higher per cent of physiological loss in weight (PLW), reduced titratable acidity, high TSS, polygalacturonase (PG) and pectin methyl esterase (PME) activities. Further, the CPPU application enhanced the climacteric rise in respiration and ethylene production during fruit ripening, shortening the shelf life of kiwifruit in comparison to untreated fruits.

    STUDIES ON CHILL UNITS REQUIREMENT IN APPLE (Malus × domestica BORKH.)
    (2015) BABITA; CHAUHAN, P.S.
    ABSTRACT The present investigations entitled “Studies on chill units requirement in apple (Malus X Domestica Borkh.)” were conducted in the experimental orchard of the Regional Horticulture Research and Training Station Mashobra, Shimla and in a private apple orchard in Aisha, Tehsil Sunni, Shimla District, during the year 2013 and 2014. The field experiment was laid out in randomized block design and replicated thrice. In experiment-1 the effective chill units (CU) and GDH°C requirements of apple at Mashobra, Shimla located 31.1°N with an elevation of 2286 m were estimated by adopting North Carolina model with base temperature (4.5°C) and (6.1°C). The estimated CU and GDH°C were 1220 and 8244 with base temperature (4.5°C), while using base temperature (6.1°C) estimated CU and GDH°C were 1222 and 5385 respectively. In experiment-2 the estimated CU and GDH°C were tested and compared with models. Using CU and GDH°C constants of all models to calculate full bloom dates of six years i.e. 2008-2014 at three locations of different elevations and compared with actual full bloom dates for different years. The difference of days of proposed models was compared with difference of days of other chill unit models. At Mashobra (2286m amsl) Shimla and Kotkhai (1815m amsl) location North Carolina (Proposed Model with base temperature 4.5°C) recorded minimum difference of two and five days, respectively. However, at Seobag (1330m amsl) Kullu location North Carolina model (base temperature 6.1°C) was found more accurate. In the experiment-3 the chilling requirement of five apple cultivars were estimated under control condition. Among all Red Fuji recorded the maximum (66.4%) and Golden Delicious recorded minimum (41%) bud burst. Red Fuji completed chilling requirement after completing 1100 CU. Cultivar, Scarlet Gala and Red Chief met the chilling requirement in between 1100 CU to 1200 CU, whereas, Starking Delicious and Golden Delicious met their chilling requirement in between 1200 CU and 1300 CU. In the experiment-4 the Starking Delicious apple trees were treated with different treatment combination of Dormex and HMO. The T5 (Dormex @ 1.0% + 2.0% HMO) was found to be the most effective in improving per cent flowering, reducing duration of flowering, increasing fruit set, improving fruit retention and enhancing maturity. However, T6 (Dormex @ 1.5% + 2.0% HMO) was significantly at par in all the parameters. The studies indicate that Dormex @ 1.0% + 2.0% HMO may be helpful improving per cent flowering, reducing duration of flowering, increased fruit set, improved fruit retention and enhanced maturity.
