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.

ThesisItem Open Access SCREENING OF NEWLY EVOLVED SELECTIONS OF CHRYSANTHEMUM (Dendranthema grandiflora Tzvelev) FOR OFF-SEASON FLOWER PRODUCTION(UHF,NAUNI,SOLAN, 2010) USHA; DHIMAN, S.R.ABSTRACT Studies on “Screening of newly evolved selections of chrysanthemum (Dendranthema grandiflora Tzvelev) for off-season flower production” were carried out at the experimental farm of the Department of Floriculture and Landscaping of Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2009. The investigations were carried out on twenty-six selections of chrysanthemum in 4 inch earthen pots containing a mixture of sand, soil and FYM in 1:1:2 proportions. Findings revealed that all twenty-six selections are suitable for off-season flower production. However, they differed significantly among themselves for various growth and flowering parameters. ‘Selection 19’, ‘Selection 21’, ‘Selection 44’, ‘Selection 64’ and ‘Selection 68’ showed optimum plant height (1.5 to 2.5 times to the height of the pot) for growing as pot mum in 4 inch earthen pots. All other selections attained more plant height than the ideal range. In general, controlled photoperiod when applied was found better for flowering in all plantings over natural. Flowering was observed much earlier under controlled photoperiod (165.83 days) with improved quality of plants as compared to natural photoperiod (240.51 days). ‘Selection 43’ (187.17 days) was earliest in flowering whereas ‘Selection 76’ (225.00 days) took maximum days to come into flowering. ‘Selection 64’ and ‘Selection 70’ remained presentable for maximum duration (48.00 days) among all selections. Based on the findings of present investigations, different selections have been assigned response groups under controlled photoperiodic conditions, which varied from 8 to 14 weeks.ThesisItem Open Access STUDIES ON THE EFFECT OF GROWING MEDIA AND PACLOBUTRAZOL ON GROWTH AND FLOWERING OF GERANIUM (Pelargonium x hortorum L.H. Bailey )(UHF,NAUNI,SOLAN, 2010) JUJHAR, SINGH; DILTA, B.S.Abstract The present investigations were carried out at the Experimental Farm of the Department of Floriculture and Landscaping of Dr. Y.S. Parmar university of Horticulture and forestry, Nauni, Solan during 2009-2010 to work out the most suitable growing media and paclobutrazol dose for producing the best quality and most presentable potted geraniums .The experiment was laid out in Completely Randomized Design (factorial) having 21 treatment combinations of growing media and paclobutrazol doses replicated thrice with five pots per treatment. Seven growing media viz.; Rhododendron forest soil : FYM : Vermicompost (1:1:1, v/v); Rhododendron forest soil : FYM : Vermicompost (2:1:1, v/v); Rai forest soil : FYM : Vermicompost (1:1:1, v/v); Rai forest soil : FYM : Vermicompost (2:1:1, v/v); Mohru Oak forest soil : FYM : Vermicompost (1:1:1, v/v); Mohru Oak forest soil : FYM : Vermicompost (2:1:1, v/v ); Soil : FYM : Sand (1:1:1, v/v) and three doses of paclobutrazol i.e., 0, 10, 20 ppm were used. The observations were recorded on plant height, plant spread, number of shoots per plant, shoot length, days to flower bud formation, number of days taken for first flower opening, length of inflorescence stalk, inflorescence diameter, number of inflorescences per plant, maximum number of inflorescences opened at a time, number of flowers per inflorescence , duration of flowering and pot presentability. Maximum plant height (25.58 cm) was recorded in Mohru Oak forest soil : FYM : Vermicompost (1:1:1, v/v). The growing media consisting of Rai forest soil : FYM : Vermicompost (2:1:1, v/v) recorded maximum values in terms of shoot length (21.39 cm), number of shoots per plant (6.71), plant spread (24.27 cm), days to flower bud formation (117.00 days), number of flowers per inflorescence (17.33), duration of flowering (123.60 days) and pot presentability (77.00), respectively. Whereas maximum inflorescence diameter (8.74 cm), number of inflorescences per plant (14.10) and maximum number of inflorescences opened at a time (9.67) were recorded in Rai forest soil : FYM : Vermicompost (1:1:1, v/v). Among the paclobutrazol doses used, 0 ppm paclobutrazol exhibited maximum plant height (30.43 cm), shoot length (25.52 cm), plant spread (26.96 cm), length of the inflorescence stalk (13.78 cm), inflorescence diameter (10.11 cm), number of flowers per inflorescence (20.24) and duration of flowering (125.30 days). However, maximum number of shoots per plant (7.02), days to flower bud formation (124.80 days), days to first flower opening (135.30 days), number of inflorescences per plant (12.56) and number of inflorescence opened at a time (8.33) were obtained with 20 ppm paclobutrazol. However, drenching of the geranium plants with 10 ppm paclobutrazol dose recorded maximum pot presentability (79.00). Hence, it is concluded that geranium plants grown in growing media consisting of Rai forest soil: FYM : Vermicompost (2:1:1, v/v) and drenched with 10 ppm dose of paclobutrazol yielded the most desirable and presentable potted geraniums.ThesisItem Open Access EFFECTS OF SUBSTRATES ON THE PROPAGATION OF HYBRID LILIES THROUGH SCALING(UHF,NAUNI,SOLAN, 2010) LYNGDOH, AIBANRIHUN; GUPTA, Y.C.ABSTRACT Studies on “Effects of substrates on the propagation of Hybrid lilies through scaling” were carried out at the experimental farm of the Department of Floriculture and Landscaping of Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2009- 10. The investigation was carried out with an objective to find a suitable substrate(s) for propagation of hybrid lilies through scaling. The experiment was conducted in a completely randomized design with fifteen media (viz. cocopeat, sawdust, sand +soil +FYM, rhododendron forest soil, rai forest soil, mohru oak forest soil, deodar forest soil, mushroom spent compost and their combination with cocopeat) and three L.A. hybrid cultivars Brindisi, Menorca and Serrada. It was found that earliest leaf emergence was observed in cv. Serrada in mushroom spent compost + cocopeat (26 days). Maximum number of leaves/scale (6.46) was recorded in cultivar Serrada planted in rhododendron forest soil + cocopeat. Leaves with more length (24.37 cm) were recorded in cultivar Brindisi planted in deodar forest soil + cocopeat. Maximum width of leaves (1.97 cm) was observed in cultivar Brindisi planted in rai forest soil + cocopeat. Maximum weight of bulblets/scale was observed in cv. Serrada in rai forest soil (1.85 g) and maximum number of bulblets/scale was observed in cv. Menorca in deodar forest soil (2.17). More percentage of scales showing leaf formation (70.00%) was observed in cultivar Brindisi planted in mohru oak forest soil. Percent response was maximum in cv. Brindissi in mohru oak forest soil + cocopeat (93.33%). Maximum size of bulblets was seen in cv. Brindissi in sawdust (12.71 mm). Maximum initial weight of scales (33.60 g) was observed in cultivar Brindisi. The maximum final weight of bulblets/replication (43.28 g) was observed in cultivar Brindisi planted in rai forest soil. Similarly propagation index was maximum (136.7 %) in cultivar Brindisi planted in rai forest soil.ThesisItem Open Access EFFECT OF GROWING MEDIA, PINCHING AND PACLOBUTRAZOL ON GROWTH AND FLOWERING OF Barleria cristata Linn.(UHF,NAUNI,SOLAN, 2010) MANASAHEB, NICHAL VIKRAM; THAKUR, PRIYANKAABSTRACT Studies on “Effect of growing media, pinching and paclobutrazol on growth and flowering of Barleria cristata L.” were carried out at the experimental farm of the Department of Floriculture and Landscaping of Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2009. Two experiments were carried out in CRD factorial design with three levels each of growing media (Soil from natural habitat, Soil from natural habitat and FYM (2:1, v/v), Soil, Sand and FYM (2:1:1, v/v)), pinching (No pinch, Single pinch and Double pinch) and paclobutrazol(0, 75, 150 ppm) having 54 treatment combinations keeping three replications each having four pots accommodating one plant per pot. Plants were raised through seeds and cuttings both. Analysis of variance showed significant differences among treatments for all the traits except for flower size. Findings revealed that seed raised plants are suitable for production of pot plants. However, seed and cutting raised plants differed significantly among themselves for various growth and flowering parameters. Seed and cutting raised plants showed optimum plant height (1.5 to 2.5 times to the height of the pot) when grown in soil from natural habitat and FYM with single and double pinching and without application of paclobutrazol for growing as pot plant. Seed raised plants recorded maximum number of secondary side shoots (20.58), leaves (177.42), flower clusters (16.17), flowers (23.58) per plant when grown in soil from natural habitat and FYM with double pinching and with the application of 75 ppm paclobutrazol and seed raised plants showed early visible bud formation and flowering when grown in all growing media without pinching and application of 75 ppm paclobutrazol. However, the cutting raised plants recorded maximum number of secondary side shoots (16.00), leaves (171.67), flower clusters (17.83), flowers (24.42) per plant when grown in soil from natural habitat and FYM with double pinching and with the application of 75 ppm paclobutrazol. Seed raised plants showed better results in case of plant height, length of primary side shoots and plant spread than cutting raised plants while cutting raised plants recorded early visible bud formation and flowering and maximum number of flower clusters per plant than seed raised plants. Based on the findings of present investigations, seed raised Barleria cristata L. plants grown in pots containing soil from natural habitat and FYM (2:1, v/v) with double pinching and application of 75 ppm paclobutrazol is recommended for better growth and flowering.ThesisItem Open Access INTEGRATED NUTRIENT MANAGEMENT STUDIES IN TUBEROSE (Polianthes tuberosa L.)(UHF,NAUNI,SOLAN, 2010) KASHYAP, REENA; CHAUDHARY, S V SABSTRACT The present investigation entitled, “Integrated nutrient management studies in tuberose (Polianthes tuberosa L.) were carried out at the Experimental Farm of the Department of Floriculture and Landscaping of Dr. Y.S. Parmar university of Horticulture and forestry, Nauni, Solan (H.P.) during 2009-2010. The experiment was laid out in Randomized Block Design having 16 treatment combinations of chemical fertilizers and biofertilizers, replicated thrice in a plot size of 1m x 1m and spacing 25cm x25cm. The observations were recorded on days taken for emergence of bulbs, percent sprouting of bulbs, number of leaves per plant, plant height, number of days taken for spike emergence, spike length, number of days taken for basal florets opening, number of florets per spike , duration of flowering, fresh weight of spike, fresh weight of 100 florets, florets size, number of spike obtained per plant, number of bulbs produced per plant, average root length per plant, weight of bulbs per plant, average size of bulbs per plant and analysis of NPK in the soil. The results revealed improvement in growth and flowering parameters of tuberose when fertilized with biofertilizers i. e. Azotobacter and PSB (each @ 5 g/ plant) alone and in combinations with chemical fertilizers. The earliest emergence of bulbs (8.16 days), more number of leaves (72.56), tallest plants (106.70 cm), early emergence of spike (61.10 days), longest spike (96.70 cm), early opening of basal florets (72.56 days), more number of florets (38.33), heaviest spike (45.68 g), maximum weight of 100 florets (122 g), produced more bulbs (25.83), longest root (19.97 cm) and more availability of K (149.94) were recorded in treatment consisting of Azotobacter + PSB + NPK @ 15, 11.2, 9.3 g/ m2. Longest duration of flowering was recorded in the treatment consisting of Azotobacter + NPK @ (15, 11.2, 9.3g/ m2), whereas, largest floret in PSB + NPK @ 15, 11.2, 9.3 g/m2, however, heaviest and largest bulbs were recorded in PSB + NPK @ 20, 15, 12.5g/m2. The availability of N and P content was maximum in Azotobacter + PSB +NPK @ 20, 15, 12.5 g/m2. However, these all parameters were found to be statistically at par with treatment consisting of Azotobacter + PSB + NPK @ 15, 11.2, 9.3 g/ m2. The parameters per cent sprouting of bulbs and number of spikes obtained per plant were not affected significantly by the different treatmentsThesisItem Open Access EFFECT OF BULB SIZE AND PLANT DENSITY ON GROWTH, FLOWERING AND POSTHARVEST HANDLING OF CHINCHERINCHEE (Ornithogalum thyrsoides Jacq.)(UHF,NAUNI,SOLAN, 2010) CHOUDHARY, RAHUL; SHARMA, B.P.Abstract The present investigation entitled “Effect of bulb size and plant density on growth, flowering and postharvest handling of Chincherinchee (Ornithogalum thyrsoides Jacq.).” was carried out at Experimental Farm of the Department of Floriculture and Landscaping, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during the year 2008-2010. Two experiments were conducted using randomized block design (factorial) in the field and completely randomized design in laboratory, respectively. In the first experiment, the vegetative growth parameters viz. days taken for sprouting (23.88, 23.71 days), plant height (47.81, 48.11 cm), stem length (25.37, 26.09 cm), number of leaves per plant (17.74, 14.27), leaf area (25.21, 26.13 cm2); the flowering parameters namely days taken to first floret opening (174.44 days), number of florets/stem (53.76, 55.38), cut stem diameter (5.30 mm), cut flower weight (17.02, 17.26 g), vase life (14.52, 14.86 days), duration of flowering (19.86, 21.26 days ); the bulb production parameters like number of bulbs per plant (2.38, 1.99), weight of bulb(s) (8.94, 8.88 g), size of bulb (2.88, 2.72 cm) were found maximum in 2.4-2.8 cm bulb size and 30 bulbs per square meter density, respectively over others. Plant spread (23.78, 23.61 cm), size of florets (1.76, 1.78 cm) were found maximum in 2.4-2.8 cm bulb size and 25 bulbs per square density, respectively. In the second experiment, days taken for opening of first floret (1.57, 1.36, 1.61 days), percent of unopened florets (14.51, 13.49, 13.28 %), weight loss (32.43, 31.55, 30.50 %) were found to be minimum whereas amount of holding solution consumed (13.00, 13.84, 15.52 ml) and vase life (14.66, 14.90, 14.69 days) were maximum in 2.4-2.8 cm bulb size and 30 bulbs per square density treated in holding solution comprising of sucrose (2%) + 8-HQC (200 ppm+ GA3 (50 ppm), respectively over control.ThesisItem Open Access STUDIES ON COMBINING ABILITY AND HETEROSIS IN FRENCH MARIGOLD (Tagetes patula L.)(UHF,NAUNI,SOLAN, 2010) KANWAR, PRIYANKA; GUPTA, Y.C.ABSTRACT The studies on heterosis and combining ability were carried out during 2008-2009 following “line x tester” analysis. Four male sterile lines namely; ms7, ms8, ms9, ms10 and 18 diverse pollinators as tester were used to produced 72 F1’s. These F1 hybrids along with 22 parental lines were evaluated during summer (2009) and rainy season (2009) in Randomized Block Design. Observations were recorded on nine quantitative traits during both the seasons. Highly significant variances for all the traits indicated the sufficient variability in the parental material for all the characters under study. The performance of F1 hybrids was much better than the mean performance of parents during both the crop seasons. Appreciable heterosis was observed in all the characters, except flower weight in summer and plant height in rainy season. Among male sterile lines, ms8 (summer season) and ms9 (rainy season) proved good general combiners, while testers Spray Mix -1, Bonita Bolero and Safari Queen were the best general combiners for both the seasons. However cross combinations viz. ms8 x Hero, ms10 x Hero, ms10 x Cupidon Yellow, ms8 x Double Dwarf Lemon were the best in terms of specific combining ability during summer. Whereas, during winter the combinations viz. ms9 x French Bonita-3, ms10 x French Bonita-3, ms9 x Bonita Bolero, ms8 x Sunkist and ms9 x French Bonita-2 were best specific combiners. The phenotypic coefficient of variation was higher in magnitude than the genotypic coefficient of variation during both the seasons. The GCA and SCA effects were found significant for almost all the character. High heritability was observed for characters number of flowers per plant and flower yield during both the seasons. In both the seasons, the ratio of s2 GCA/ s2 SCA was less than unity for all the characters showing the preponderance of dominance variance. Thus suggesting selection in the later generations as more effective. None of the hybrids performed consistently during both the seasons. The best hybrid in summer season on the basis of yield per plant was ms8 x FM-786(145.91g/plant) while the best hybrid during rainy season on the basis of yield per plant was ms10 x French Bonita-1(155.73g/plant)
