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 PROPAGATION OF HYBRID LILIES THROUGH SCALING
    (2016) KAUR, RUPINDER; KASHYAP, BHARATI
    ABSTRACT The present investigation entitled, “Studies on propagation of hybrid lilies through scaling” was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan, (H.P) during 2014-2015. The first experiment was laid out in a Completely Randomized Design (factorial) consisting of three cultivars, three media and four auxin treatments (control, NAA 500 ppm, IBA 500 ppm, NAA 500 ppm + IBA 500 ppm). Among the cutivars, maximum weight of bulblets/scale (0.51 g) and propagation index (41.90%) was recorded in cv. ‘Batistero’, maximum number of bulblets/scale (2.53) in cv. ‘Jazz It Up’ and bulblet diameter in cv. ‘Courier’ (8.60 mm). Among the different auxin treatments, dipping the scales in NAA 500 ppm before planting produced best results for per cent sprouting (65.56 %), days taken for sprouting (66.19 days), sprout length (15.83 cm), number of leaves/scale (2.21), percentage of scales showing bulblet formation (69.63 %), number of bulblets/scale (2.68), weight of bulblet(s)/scale (0.57 g), bulblet diameter (9.42 mm) and propagation index (39.77 %). Out of the media, per cent sprouting (66.67 %), days taken for sprouting (73.36 days), sprout length (16.41cm), percentage of scales showing bulblet formation (67.50 %), number of bulblets/scale (2.67) and propagation index (38.16 %) was maximum in ‘cocopeat’ whereas, number of leaves/scale (2.22), weight of bulblet(s)/scale (0.68 g) and bulblet diameter (9.86 mm) was observed maximum in perlite + vermiculite. Finally, it was concluded that an application of 500 ppm NAA and planting in cocopeat was found to be the best treatment for propagation of lilium through scaling. In the second experiment, the scales of fifteen Asiatic and LA hybrid lily cultivars were planted in cocopeat after dipping in NAA 500 ppm. It was found that, cv. ‘Batistero’ excelled others with respect to most of the parameters and maximum propagation index (80.48 %) was also recorded in this cultivar.

    STUDIES ON PLANTING DENSITY AND FERTILIZER LEVELS ON SEED PRODUCTION OF TEMPERATE CARROT (Daucus carota L.)
    (2016) ANIT, KUMAR; SHARMA, RAJENDER
    ABSTRACT The present investigation, “Studies on planting density and fertilizer levels on seed production of temperate carrot (Daucus carota L.)’’ was carried out at Vegetable Research Station, Kalpa, of Regional Horticultural Research & Training Station and Krishi Vigyan Kendra, Kinnaur (HP), Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, H.P. from April to October 2015. The experiment was laid out in Randomized Block Design (Factorial) in the field. The treatment combinations comprised of four planting densities (D) viz., D1 (45x15 cm), D2 (45x30 cm), D3 (30x30 cm) and D4 (30×15 cm) four fertilizer levels (F) viz., F1 (75% RD NPK), F2 (100% RD NPK), F3 (125% RD NPK) and F4 (150 % RD NPK). The observations were recorded in the field on plant height (cm), days to flowering initiation, days to 50% flowering, number of primary umbels plant-1, number of secondary umbels plant-1, weight of primary umbels plant-1, seed yield plant-1 (g), seed yield plot-1 (g), seed yield (q ha-1), total biomass plant-1 and benefit: cost ratio. While the observations recorded in the laboratory were germination (%), seed vigor index-I & II, available NPK before and after experiment. Analysis of variance showed significant differences among the treatment combinations for all the characters studied. Non-significant differences of planting density, fertilizer levels as well as interaction were observed on electrical conductivity and pH. On the other hand, available NPK status was influenced only by fertilizer levels. The treatment combination F4D2 (150 % RD NPK and 45x30 cm) performed best for all horticultural traits, seed yield characters and seed quality characters. Therefore, planting density 45x30 cm in combination with 150% RD NPK i.e. F4D2 can be recommended for commercial seed production of carrot.

    (2016) GULERIA, KRITIKA; CHAUDHARY, S.V.S.
    ABSTRACT The present investigations entitled, “Studies on the effect of pruning dates on growth and flowering of Rose (Rosa hybrida L.) cv. ‘Super Star’ ” was carried out at the Experimental Farm of Department of Floriculture and Landscape Architecture, Dr Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2014–2015. The experiment was laid out in Randomized block design (RBD). The plants were pruned at different dates at one month intervals wef. 21st October, 2014 up to 20th February, 2015. Among different pruning dates, plants pruned on 20th December, 2014 resulted superior in growth and flowering parameters i.e. numbers of shoots (12.60), numbers of leaves (14.02), numbers of cut stems (11.30), stem length (62.16 cm), diameter of cut stem (10.48 mm), longer vase life (10.83 days), maximum weight of cut stem (41.33 g), numbers of flower buds (13.10), length of flower bud (50.35 mm), diameter of flower bud (40.25 mm), diameter of flower (10.41 cm) and flower yield (13.23). However, plant height (90.42 cm) and petals per flower (47.78) resulted maximum in October and November pruning respectively. The earliest flower bud initiation (36.17days) and maximum pedicel length (9.20 cm) was seen in plants pruned on 20th February, 2015 (T5). The flower regulation in rose for longer period obtained in 20th December pruning. Among different flowering flushes, flush-I resulted better in all vegetative and flowering parameters as compared to flush-II & III. Hence, it can be concluded that pruning performed on 20th December, 2014 is best for all growth and flowering parameters except few, under mid hill zone of Himachal Pradesh.

    CANOPY MANAGEMENT OF REJUVENATED APPLE TREES THROUGH PRUNING AND PROHEXADIONE-Ca TREATMENTS
    (2016) CHAUHAN, AMAN; MANKOTIA, M. S.
    ABSTRACT The present investigation entitled “Canopy management of rejuvenated apple trees through pruning and prohexadione-Ca treatments” was carried out at Regional Horticultural Research and Training Station, Mashobra, Shimla during the years 2015 and 2016. Pruning treatment with no heading back-only thinning out suppressed the vegetative growth and markedly improved the fruit set, yield and yield efficiency. It also improved red colouration and firmness of the fruits at harvest. Heading back (25% removal of one year old growth) increased vegetative growth and improved fruit quality in terms of size and total soluble solids. Two foliar applications of prohexadione-Ca at a concentration of 150 ppm significantly restricted the vegetative growth. Further, it was found to be effective in improving fruit set, yield efficiency, fruit colour and firmness. Return bloom on the basis of blossom density was improved by combining no heading back-only thinning out pruning cuts with two foliar applications of prohexadione-Ca at a concentration of 150 ppm. In order to regulate vegetative growth and fruiting in rejuvenated apple trees, the combination of no heading back-only thinning pruning cuts and two foliar applications of prohexadione-Ca at a concentration of 125 ppm and 150 ppm can be recommended for sustainable apple production.

    (2016) CHAUHAN, AKRITI; KRISHAN, KUMAR
    ABSTRACT The present investigation entitled “Characterization of some peach [Prunus persica (L.) Batsch] germplasm accessions” was carried out in the Department of Fruit Science, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni-Solan. 15 peach accessions namely July Elberta, Early Redhaven, Suncrest, TropicSweet, Paradelux, Saharanpur Prabhat, Earligrande, Flordaprince, TropicSnow, Flordaglo, Vallegrande, TropicBeauty, Pratap,Shan-i-Punjab and Glohaven were evaluated for their tree, foliage, floral and fruit characters. Yield efficiency was recorded maximum (0.54%) in Pratap whereas minimum (0.18%) in Early Redhaven. Serration was observed to be varied from crenate (4 accessions) to shallow serrate (6 accessions) to deep serrate (5 accessions). Nectaries (glands) were observed as globose in Vallegrande, Earligrande, Paradelux, Pratap and Shan-i-Punjab whereas reniform in rest of the accessions. Time of leaf bud burst was earliest in Flordaprince on 11th January followed by Saharanpur Prabhat on 12th January and July Elberta was the last on 5th February. Petal shape was observed as circular in 5 accessions and medium ovate in 10 accessions. The flower initiation was found to be earliest in Saharanpur Prabhat on 10th January followed by Flordaprince on 11th January whereas July Elberta was the last on 4th February. Maximum fruit length (53.69 mm) was recorded in Early Redhaven and minimum (37.37 mm) in Saharanpur Prabhat whereas fruit breadth was recorded maximum (54.38 mm) in Flordaprince and minimum (42.62 mm) in July Elberta. Mucron tip was present in seven accessions whereas absent in eight accessions. Flesh colour was observed as white in Saharanpur Prabhat, Flordaglo and TropicSnow whereas yellow in remaining peaches under study. Adherence of stone to flesh was absent in July Elberta, Early Redhaven, Suncrest, Pratap, Shan-i-Punjab, Glohaven, TropicSweet, Saharanpur Prabhat and TropicSnow whereas present in rest of the accessions. From the present study, it can be concluded that all the accessions studied recorded variation for most characters and the descriptive database so developed will help in DUS testing and in multiplication of true to type planting material.

    EFFECT OF NITROGEN SOURCES ON GROWTH, YIELD AND NUTRITIONAL STATUS OF APPLE (Malus × domestica Borkh.) CV. OREGON SPUR
    (2016) AMAR, JEET; SHARMA, N.C.
    ABSTRACT The present studies were carried out in a private orchard at Matiana (Shimla) during the year 2014-2015. Five years old trees of uniform size and vigour planted at 3.0 x 3.5 m spacing were subjected to 10 treatments viz. calcium nitrate (2.25 kg), urea (760 g), calcium nitrate + urea (1.125kg and 380g), NPK mixture 12:32:16 and calcium nitrate (550g and 1.830kg), N:P:K mixture 12:32:16 and urea (550g and 620g), Di-ammonium phosphate and calcium nitrate (380g and 1.820kg), di-ammonium phosphate and urea (380g and 620g), NPK mixture 12:32:16 and calcium nitrate + urea (550g and 920g + 310g), diammonium phosphate and calcium nitrate + urea (380g and 910g + 310g), calcium ammonium nitrate/control (1.4 kg). The treatments were replicated thrice and experiment was laid out in randomized block design. Tree height, spread, volume, leaf area, annual shoot growth and chlorophyll content were significantly increased by calcium nitrate + urea application, however, combination of di-ammonium phosphate and urea resulted in lowest vegetative growth attributes. The calcium nitrate + urea treatment also had significantly improved fruit set, yield and yield efficiency and reduced fruit drop. Trees subjected to calcium nitrate + urea treatment exhibited significantly higher fruit weight, total soluble solids, total and reducing sugars and lowest titratable acidity. However, maximum fruit length and anthocyanin content were observed with calcium ammonium nitrate and fruit diameter as well as firmness with the application of calcium nitrate. The maximum leaf N, K and Mg contents were recorded in calcium nitrate + urea treatment but leaf P and Ca were observed highest in trees treated with combination of di-ammonium phosphate and calcium nitrate and calcium nitrate, respectively. Soil pH, EC and OC were not influenced by various nitrogen sources, however, significantly higher soil N and K were recorded under calcium nitrate + urea treatment but maximum soil P was observed with di-ammonium phosphate and calcium nitrate application.

    STUDIES ON GENETIC VARIABILITY IN SOME NECTARINE [Prunus persica (L.) Batsch var nucipersica] CULTIVARS FOR DIFFERENT HORTICULTURAL TRAITS
    (2016) SHARMA, NIVEDITA; DOGRA, R.K.
    ABSTRACT The present investigation entitled "Studies on genetic variability in some nectarine [Prunus persica L. Batsch var nucipersica] cultivars for different horticultural traits" was carried out at the Model Farm, Directorate of Research, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H P) during 2014-16 with the objective of studying the variability in different nectarine cultivars and to study the association between yield and its dependent variables. Five cultivars of nectarine namely, Mayfire, Sunrise, Silver King, Snow Queen and Spring Bright were evaluated for their plant growth, floral, fruiting and chemical characteristics. Analysis of variance showed significant differences among all the genotypes for all the characteristics under study viz., tree height, tree spread, trunk girth, tree volume, annual shoot growth, leaf area, date of opening of first flower, date of full bloom, date of opening of last flower, duration of flowering, flower intensity, fruit set, time of maturity, days from full bloom to harvest, fruit size , fruit shape, fruit color, fruit weight, fruit volume, fruit firmness, stone size, stone weight, pulp to stone ratio, yield per tree, yield efficiency, total soluble solids, titratable acidity, total sugars, reducing sugars, non-reducing sugars and sugar:acid. The genotype Snow Queen recorded highest yield and performed better for other important horticultural traits among different genotypes. Spring Bright was found to be the dwarfest among the studied genotypes. These may be suggested for cultivation in mid-hill conditions of Himachal Pradesh. High heritability coupled with high genetic gain was obtained tree volume indicating some scope for their improvement through selection. High heritability coupled with moderate genetic gain was obtained for fruit yield per tree, fruit volume, trunk girth, stone length, total soluble solids, total sugars, fruit firmness, tree spread, yield efficiency, sugar-acid ratio and reducing sugars. Hence, selection can prove effective for improvement in fruit yield and other traits. A highly significant and positive phenotypic and genotypic correlations of yield were found with tree spread, tree volume, fruit length and fruit weight. Maximum positive direct effect cited towards yield were contributed by fruit weight, tree spread, stone length, flower intensity, stone weight, total soluble solids, number of days from full bloom to maturity, pulp to stone ratio, tree height, duration of flowering, fruit set and trunk girth.

    (2016) SALAM, PRIYADARSHNI; GUPTA, Y.C.
    ABSTRACT The present investigations entitled, “Effect of planting density and foliar application of nitrogen on multiplication of gladiolus (Gladiolus hybrida L.) through cormels” was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during the year 2014 and 2015. The experiment was laid out in a Split Plot Design with three planting density i.e. 100, 120 and 140 cormels/m2 and number of foliar spray of nitrogen (500 ppm) viz., 0, 15, 9 and 6, altogether 12 treatment combinations of planting density and foliar spray of nitrogen replicated thrice. Among different planting density, the lowest density i.e. 100 cormels/m2 recorded maximum values for plant height (35.97 cm), number of leaves per plant (5.25), leaf length (31.93 cm), leaf width (1.54 cm), number of cormels/plant (6.35), weight of cormels/plant (1.25 g), cormel size (0.89 cm), weight of corms/plant (27.29 g), corm size (3.56 cm), propagation index (4001.81), NPK content of leaves (2.43, 0.24, 2.37%), available NPK content of soil (222.60, 35.94, 225.53 kg/ha), total chlorophyll content of leaves (1.43 mg/g). However, number of cormels/m2 (439.93), weight of cormels/m2 (91.66 g), number of corms/m2 (70.33), weight of corms/m2 (1399.34 g), minimum crop duration (205.55 days) was recorded with the highest density of 140 cormels/m2. As regards the effect of foliar spray of nitrogen, plant height (36.57 cm), number of leaves per plant (5.41), leaf length (32.46 cm), leaf width (1.59 cm), number of cormels/plant (7.51), number of cormels/m2 (573.90), weight of cormels/plant (1.51 g), weight of cormels/m2 (117.74 g), cormel size (0.92 cm), number of corms/m2 (70.83), weight of corms/plant (28.41 g), weight of corms/m2 (1569.77 g), corm size (3.87 cm), propagation index (4395.13), NK content of leaves (2.52, 2.42%), available NPK content of soil (229.47, 37.10, 234.27 kg/ha), total chlorophyll content of leaves (1.48 mg/g) were recorded with the highest number of foliar spray of nitrogen i.e. 16 numbers of foliar spray of nitrogen (500 ppm). However, minimum crop duration (199.56 days) was recorded in control where no foliar spray of N has been given. Hence, it is concluded that the lowest planting density in combination with the highest number of foliar spray of nitrogen gave best results for the desirable growth, corms and cormels parameters of the gladiolus cv. Solan Mangla.

    (2016) THAKUR, YAMINI; SANTOSH, KUMARI
    ABSTRACT The present investigation entitled “Genetic evaluation of garlic (Allium sativum L.) germplasm” was carried out at Vegetable Research Farm, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Rabi season, 2014-15 and 2015-16. The experiment was laid out in RCBD with three replications comprising of thirty six diverse genotypes of garlic including Agrifound Parvati as check variety. The observations were recorded on various characters viz., plant height, number of leaves per plant, days to maturity, neck thickness, bulb weight, bulb breadth, bulb length, clove weight, clove breadth, clove length, number of cloves per bulb, number of bulbs per kg, weight of 100 unpeeled cloves, weight of 100 peeled cloves, bulb yield per plot, bulb yield per hectare, peeling index, drying percentage, total soluble solids, oleoresin content and stemphylium blight intensity. Analysis of variance revealed highly significant differences among genotypes for all the characters under study. Genotypes viz., Kandaghat Selection, LC-1, SG-30, LC-2 and LC-3 were found promising in terms of yield and yield contributing characters and performed better than check variety. Genotypes viz., G-189, G-282 and G323 were earliest in maturity. Maximum peeling index and drying percentage was recorded in G-282 and maximum percentage of oleoresin content in SG-10. LC-4 was found to have high percentage of total soluble solids and drying percentage. Genotypes viz., Kandaghat Selection, LC-1, LC-2, LC-3, LC-4, LC-5, SG-1, SG-2, SG-4, SG-9, SG-20, SG-21, SG-22, SG-26 and SG-27 exhibited field resistance against the stemphylium blight. High heritability in association with high genotypic coefficient of variability and genetic gain were recorded for bulb weight, clove weight, number of bulbs per kg, bulb yield per plot, bulb yield per hectare, oleoresin content and stemphylium blight intensity. Correlation studies revealed that yield per plot was positively and significantly associated with plant height, number of leaves per plant, days to maturity, neck thickness, bulb weight, bulb breadth, bulb length, clove weight, clove breadth, clove length, weight of 100 unpeeled cloves and weight of 100 peeled cloves whereas, negatively and significantly with number of cloves per bulb, number of bulbs per kg and drying percentage. The path coefficient analysis depicted that bulb weight had the maximum positive direct effect on bulb yield per plot.
