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 Genetic studies on yield and quality traits in cucumber (Cucumis sativusL.)(DYSPU, 2013) Sandeep Kumar; Ramesh KumarThe present studies entitled “Genetic studies on yield and quality traits in cucumber (Cucumis sativus L.)” were carried out at the Experimental Research Farm of the Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 2011 and 2012. The experimental material for the present study comprised of F 1 population of forty eight crosses, developed by crossing 16 lines and 3 testers. All the parents (16 lines and 3 testers) and their hybrids (48) along with the standard checks (KH-1 and Pusa Sanyog) were planted in a Randomized Complete Block Design for their comparative evaluation. The observations wererecorded on days to first female flower appearance, node number bearing first female flower, days to marketable maturity, fruit length (cm), fruit breadth (cm), average fruit weight (g), fruit colour, number of marketable fruits per plant, harvest duration (days), marketable yield per plot (kg) & per hectare (q), total soluble solids ( o B), cucurbitacin content (µg/100g), incidence of fruit fly (%), severity of powdery mildew (%), downy mildew (%) and angular leaf spot (%), seed germination (%) and seed vigour index-I and II. The analysis of variance indicated highly significant differences among the genotypes for all the traits studied. Experimental results revealed that five lines viz.,LC-1-1, CGN-20953, LC-2-2, CGN-19533 and Gyne-5 and two testers viz., K-75 and Poinsette were found superior on the basisof mean performance and general combining ability studies. Five cross combination viz., LC-1-1 x K-75, LC-2-2 x Poinsette, CGN-19533 x K-75, Gyne-5 x K-75 and CGN-20953 x Poinsette were found best on the basis of mean performance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be tested further at multilocations before releasing as a substitute of already exiting hybrid varieties of cucumber in Himachal Pradesh and in India as well.ThesisItem Open Access Heterosis, combining ability and gene action studies in tomato (Solanum lycopersicum L.)(YSPU, 2014) Gautam, NidhishThe present studies entitled “Heterosis, combining ability and gene action studies in tomato (Solanum lycopersicum L.)” were carried out at the Experimental Research Farm of the Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 2012 and 2013. The experimental material for the present study comprised of six parents and F1 population of fifteen crosses, developed by crossing these six diverse tomato lines in diallel design (excluding reciprocals). All the parents and their hybrids along with the standard check (Naveen) were planted in a Randomized Complete Block Design for their evaluation in Kharif, 2013. The observations were recorded on days to first flowering, days to marketable maturity, average fruit weight (g), number of fruits per plant, harvest duration (days), fruit yield (kg/plant, kg/plot and q/ha), plant height (cm), number of locules per fruit, pericarp thickness (mm), whole fruit firmness (g/0.503cm2), total soluble solids (oBrix), ascorbic acid content (mg/100g), lycopene content (mg/100g), buckeye rot incidence (%) and Alternaria blight severity (%). The analysis of variance indicated highly significant differences among the genotypes for all the traits studied. Experimental results revealed that three lines viz., Solan Lalima, UHFT-9 and UHFT-10 were found superior on the basis of mean performance and general combining ability studies. Five cross combinations viz., UHFT-9 x Solan Lalima, UHFT-10 x Solan Lalima, UHFT-55 x Solan Lalima, UHFT-22 x Solan Lalima and UHFT-9 x UHFT-10 were found best on the basis of mean performance, specific combining ability and heterosis studies. Hence, these hybrid combinations can be tested further at multiplications before releasing as a substitute of already existing hybrid varieties of tomato in Himachal Pradesh and in India as well. Gene action studies indicated predominance of dominance effects in governing most of the traits suggesting exploitation of hybrid vigour and developing hybrids for improvement of these traits in tomato on the basis of present studies.ThesisItem Open Access Genetic studies for yield and quality traits in tomato (Solanum lycopersicumL.)(YSPU, 2016) Rakesh; Sharma, Hem RajThe present investigation entitled “Genetic studies for yield and quality traits in tomato (Solanum lycopersicum L.)” was carried out at the Experimental Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2014-15 and 2015-16 to know the extent of heterosis, assessing combining ability and generating information on gene action. Six diverse tomato genotypes were crossed in a diallelb fashion (excluding reciprocals) during Kharif2014-15 and in the next year fifteen crosses alongwith 6 parents and one standard check (Naveen 2000+) were evaluated in RCBD. Analysis of variance showed significant differences among all the genotypes for all the characters under study. The genotypes, EC-1055 and EC-1057 among parents while Solan Lalima x EC-1057 and Solan Lalima x EC-1058 among cross combinations were found superior for earliness. Heterobeltiosis for fruit yield and quality traits was recorded significantlypositive in Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058. Maximum negative heterosis for buck eye rot incidence and alternaria blight severity was observed in Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058. For yield and component traits Solan Lalima was good general combiner. Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were good specific combiners for fruit clusters per plant, number of fruits per cluster, number of fruits per plant, harvest duration and fruit yield traits. Solan Lalima and UHF-55 were good general combiners for total soluble solids, lycopene content and ascorbic acid content. Cross combinations viz.Solan Lalima x EC-1055, Solan Lalima x EC-1057 and Solan Lalima x EC-1058 were good specific combiners for all quality traits. Solan Lalima was good general combiner for buck eye rot incidence, alternaria leaf blight severity, septoria leaf blight severity and fruit borer infestation. The estimates of σ 2 g/σ 2 s (predictability ratio) were found to be < 1 for almost all the traits included in this study except for plant height, fruit size, buck eye rot incidence and fruit borer infestation indicated predominance of non additive gene action.ThesisItem Open Access Response of tomato genotypes to different mulches and biofertilizers(DYSPU, 2013) Sandeep Kumar Singh; Sharma, Hem RajThe present study entitled “Response of tomato genotypes to different mulches and biofertilizers” was carried out at the experimental farm of Horticulture Research Station, Kandaghat, Dr Y S Parmar U H F, Solan, Himachal Pradesh, during 2011 and 2012. The experiment comprised of three genotypes (V 1 -Naveen 2000 + , V2-Sun-7711 and V3-Solan Lalima), three mulches (M0-No mulch, M1-Pine needle mulch and M 2- black polyethylene) and three biofertilizers (B0-recommended NPK, B1-100 % NPK + Azotobacter(1g/plant) + PSB (1g/plant) and B2-75 % NPK + Azotobacter(1g/plant) + PSB (1g/plant). Thus, there were 27 treatment combinations which were replicated thrice in Split-Split Plot Design. The observations were recorded on number of days to first flowering, number of days to first harvest, harvest duration, number of fruits/plant, average fruit weight (g), fruit length (cm), fruit width (cm), plantheight (m), yield (kg/plant), yield (kg/plot), yield (q/ha), pericarp thickness (mm), TSS ( 0 Brix), acidity (%), shelf life (days), fruit firmness (g per 0.503cm 2 ) ascorbic acid (mg/100g), lycopene content (mg/100g), incidence of buckeye rot (%), severity of bacterial leaf spot (%), early blight (%), septoria blight (%) available nitrogen (kg/ha), phosphorus (kg/ha), potash (kg/ha), organic carbon (%), pH and electrical conduvtivity. Among varieties, maximum yield was observed with the variety V2(Sun-7711), but the fruit quality characters as well as the ability to resistdisease incidence/severity was observed with the variety V3(Solan Lalima). Among the mulch materials the M2 (Black polythene) and biofertilizers B1 (100% NPK + Azotobacter(1g/plant) + PSB (1g/plant) were recorded to be the best regarding the fruit yield, quality and soil nutrient status as well as disease incidence/severity. The first order interactions viz., varieties x mulch, biofertilizers x mulch and varieties x biofertilizers significantly affected most of the characters under study. Maximum fruit yield was obtained with treatment combinations of V2M2 (Sun-7711 applied with black polyethylene mulch), B2M2(75% NPK + Azotobacter(1g/plant) + PSB (1g/plant) applied with black polyethylene mulch) and V 2B2(Sun-7711with 75 % NPK + Azotobacter(1g/plant) + PSB (1g/plant). Further in three factor interaction, the highest fruit yield (1037.33 q/ha) with maximum net returns (Rs. 436059.51) and highest cost benefit ratio (1:5.28) was obtained with the treatment combination of Sun-7711, 75% NPK + Azotobacter(1g/plant) + PSB (1g/plant) and black polyethylenemulch (V2B2M2).ThesisItem Open Access Comparative efficiency of organic, inorganic and integrated nutrient management on growth, yield and quality of sprouting broccoli (Brassica oleracea L. var. italica) cv. Green Head(YSPU, 2014) Prince Kumar; Bhardwaj, M.L.The present investigations entitled "Comparative efficiency of organic, inorganic and integrated nutrient management on growth, yield and uality of sprouting broccoli (Brassica oleracea L var italica Plenck) cv. Green Head" was carried our during rabi season of 2011- 12 and 2012-13 in the Experimental Farm of the Department of Vegetable Science, 1)1' Y S Parmar University of Horticulture and Forestry, Nanni, Solan (HP). Twenty five treatments combinations of inorganic (N, P and K), organic verrnicornposr, neern manure and FYM) and biofertilizers (Azotobacter and PSB) were replicated thrice in a plot having dimensions of 3.00 m x 2.70 In The experiment was laid out in a randomized complete block design and a spacing of 60 Clll x 45 em was followed Seed of sprouting broccoli cv. Green Head was sown in the nursery bed on 2nd week of September, 2011 and 2012. One month old seedlings were transplanted on 2nd week of October during both the years. The data were recorded 011 days taken to 50 per cent heading, plant height at maturity (ern), number of leaves per plant, head size (ern"), average head weight (g), number of marketable secondary heads/plant, average secondary head weight (g), yield pel' plot (kg) and per hectare (q), severity of black rot (%), vitamin A (I U), vitamin C (mgllOOg), protein (0/" by weight): uptake of N:P,K and micronutrient, (Zn, Cu, Mn, Fe), available N,P.K content in the soil before and after harvest and benefit: cost ratio. The results revealed that recommended dose of fertilizers + Azotobacter (5kglha) + PSB (5kglha) was rated as the best treatment (TI6) for characters like head size (em), average head weight (g), number of marketable secondary heads/plant, average secondary head weight (g), yield per plot (kg) and pel' hectare (q) and benefit: cost ratio followed by T2L i.e .. recommended dose of fertilizers (33.3 %) + FYM (33.3 %) + VC (33..3 %) + Azotobacter (5.0 kg/ha) + PSB (5.0 kg/ha) for characters like days taken to 50 per cent heading, plant height at maturity (em), number of leaves per plant, severity of black rot (%), vitamin A (I U), vitamin C (mglIOOg), protein (% by weight), uptake of N,P,K and micronurrients (Zn, Cu, Mn, Fe), available N,P,K content in the soil before and after harvest consistently during both the years. However, minimum values for all the characters studied were recorded by sole application of different organic manures and biofertilizers. It was concluded that integration of bioferti lizers, organic manures and reduced level of inorganic fertilizers gave better results and hence, there is a great scope of improvement in growth, yield, and quality of sprouting broccoli.ThesisItem Open Access HETEROSIS, COMBINING ABILITY AND GENE ACTION STUDIES IN TOMATO (Solanum lycopersicum L.)(2014) GAUTAM, NIDHISH; MANISH KUMARABSTRACT The present studies entitled “Heterosis, combining ability and gene action studies in tomato (Solanum lycopersicum L.)” were carried out at the Experimental Research Farm of the Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 2012 and 2013.
