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.)

ThesisItem Open Access Site Suitability analysis for fruit crop production using satellite remote sensing and GIS based multi-criteria evaluation approach(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2024-05-20) Shahid Khan; Vikas Kumar SharmaThe present study entitled “Site Suitability analysis for fruit crop production using satellite remote sensing and GIS based multi-criteria evaluation approach” was carried out during 2022-2023. In the current study, analysis of soil data, weather data and satellite data along with physiographic mapping was conducted using Arc-GIS 10.6 software. For the future analysis reclassification of maps was done. The analytical hierarchy process approach was adopted to derive the site suitability map, supplemented by data obtained from a survey based on questionnaire. The study has delineated the potential suitable area for fruit production of Mango, Guava, Pomegranate, Citrus and Litchi in Una. The final suitability map was categorized into two classes: Agriculture and Barren land. It showed that agriculture class had maximum area under the moderately suitable class (110.10sq.km.). Whereas barren land class exhibited maximum area under moderately suitable (222.29 sq.km.), followed by highly suitable (112.99sq.km), while the not suitable class had the smallest area (106.29 sq.km.). The Study highlights the necessity for developing suitable land use planning to optimize the productivity of fruits in highly suitable areas. It identifies potentialities and suggests further policy support to boost fruit production in Una district.ThesisItem Open Access Evaluation of mango (Mangifera indica L.) cultivars in subtropics of Himachal Pradesh(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2024-02-17) Sharma, Upma; Kaler, Rajesh KumarThe study entitled Evaluation of mango (Mangifera indica L.) cultivars in subtropics of Himachal Pradesh, was conducted at the Regional Horticulture Research and Training Station (RHRTS), Jachh of Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni (Solan during 2022 and 2023). The research trial was laid out in ‘Randomized Block Design and the experimental material comprised of nine mango cultivars (Arka Anmol, Arka Aruna, Arka Puneet, Alphonso, Ratna, Sindhu, Goa Mankurad, Kesar and Pairi) planted at a spacing of 6×5 m. Significant variability existed in cultivars with respect to tree, foliage, flowering and fruit characters. Ratna had the maximum plant height (7.5 m) and tree spread (7.5 m) whereas, the minimum plant height (4.6 m) and tree spread (4.8 m) was recorded in Goa Mankuard. The maximum panicle length (29.60 cm) and width (18.9 cm) was recorded in cultivars Arka Aruna and Alphonso while, the minimum panicle length (18.80 cm) and width (19.8 cm) in cultivar Sindhu. The cultivar Pairi had the maximum fruit length (10.1 cm) and fruit width (8.1 cm), fruit weight (211.1 g), fruit volume (202.7 cm3), pulp weight (168.4g), pulp/stone ratio (9.1), stone length (7.4cm) and fruit yield (28.3 kg/plant) while, the minimum fruit length (5.7 cm) was recorded in Arka Anmol and the minimum fruit width (4.7cm) in Sindhu.n However, the minimum fruit weight (93.8 g) was observed in Arka Puneet. The minimum fruit volume (87.7 cm3) and pulp weight (55.0g) were found in cultivar Sindhu, the minimum pulp/stone ratio (2.6%) and minimum stone length (4.9 cm) were found in cultivar Arka Puneet and minimum yield (14.5 kg/plant) was found in Alphonso. The maximum TSS (18.5 0B) and ascorbic acid (41.7 mg/100g) were found in the cultivar Kesar, while the minimum TSS (16.60B) was observed in Sindhu and minimum ascorbic acid (35.4 mg/100g) was recorded in cultivar Goa Mankuard. The maximum total sugar was observed in cultivar Alphonso (15.6 %). The highest (35.9 %) incidence of mango malformation was recorded in the cultivar Ratna whereas, the lowest (6.3%) in cultivar Arka Anmol. On the basis of performance in terms of growth parameters Ratna was superior to all the other cultivars whereas, Pairi was found superior in terms of fruit quality parameters. However, Kesar had better biochemical quality. The fruit yield per plant had significant and positive correlation with fruit volume, fruit weight, petiole length, pulp/stone ratio, titratable acidity, tree girth, leaf length, peel positive and direct effect on fruit yield was recorded in fruit weight followed by pulp/stone ratio.ThesisItem Open Access Effect of PGRs application on ‘mrig-bahar’ of guava under sub-Himalayan subtropical growing conditions(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2024-02-08) Sharma, Aprajita; Sharma, Shashi KumarThe studies on the “Effect of PGRs application on ‘mrig-bahar’ of guava under sub-Himalayan subtropical growing conditions” were conducted in the experimental orchard of the Department of Fruit Science, College of Horticulture and Forestry, Neri, Hamirpur during the year 2022 and 2023 with the aim to improve the yield and quality of guava cv. L-49 raised under a high-density system of planting (2x1m). An experiment with three-factor treatments (benzyladenine (BA) foliar application at fruit set, paclobutrazol (PBZ) soil applications during July and August and ethrel at the onset of fruit maturity) was laid out in RBD factorial layout with binary treatments of BA- 0, 50 ppm; PBZ- 0, 10 g/plant and ethrel- 0, 500 ppm. The combined application of BA foliar spray at fruit set and PBZ soil drenching during July and August resulted in the minimum fruit drop of 39.3 % which was significantly lower than control. Ethrel foliar application at the onset of fruit maturity reduced the time from fruit set to harvest by around 3 days. The fruit physical parameters, like size (6.3 cm), weight (137.0 g), volume (124.0 cm3), specific gravity (1.07), and yield (4.21 kg) were obtained better with a conjoint application of BA, PBZ, and ethrel. However, ethrel alone exhibited better fruit firmness. Ethrel and PBZ applications significantly improved fruit surface yellowness index, with the highest index value of 89.8 recorded under this treatment combination. Biochemical fruit quality parameters such as TSS (13.6 ⁰B) and total sugars (9.3%) were highest with the combination of PBZ and ethrel, while individual PBZ application increased ascorbic acid and pectin content. PBZ application exerted control over vegetative growth parameters and resulted in higher leaf carbohydrate and phenol content. Overall, it has been concluded that the soil application of PBZ at 10 g/plant during July and August significantly improves fruit quality and yield parameters while controlling vegetative growth, also. Conjoint application of BA at fruit set @ 50 ppm foliar spray, PBZ soil application @ 10 g/plant (2 applications in July and August) and ethrel spray @ 500 ppm at the onset of maturity was the best treatment combination for early harvest of fruit with better colour, firmness and other quality fruit parameters.ThesisItem Open Access Genetic variability studies in seedling mango genotypes of Dada Siba block, district Kangra(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2024-02-07) Kajal; Kaler, Rajesh K.The present study “Genetic variability studies in seedling mango genotypes of Dada Sibablock, district Kangra” directed to evaluate variation among already present mango trees of seedling origin. A total number of genotype is 20, which is noticed across mango growing area of Dada Siba, district Kangra during 2022-2023. Selected genotypes were recorded with the tree height and trunk girth ranged between (8.1 to 22.2 m) and (0.36 to 2.4 m), with erect to spreading in growth habit, oblong to broadly–pyramidal in crown shape and sparse to dense density of foliage. There were very low variations observed in leaf and floral characters. Physical characters like fruit length (8.43 cm), fruit width (5.63 cm), fruit volume (170.57 cm3), fruit weight (164.93 g), pulp weight (101.60 g), peel thickness (1.25 mm), pulp: stone ratio (3.33), stone weight (33.03 cm), TSS (19.97 o B), acidity (0.26%) and ascorbic acid (31.60 mg/100g) were recorded. The estimates of PCV and GCV were high for pulp weight, fruit weight and pulp ratio. High heritability along with high genetic advance was observed in pulp weight, peel thickness, fruit volume, pulp:stone ratio, and fruit weight. Positive and significant correlation was observed in panicle width, fruit length, fruit width, fruit volume, pulp weight, peel thickness, pulp: stone ratio, stone length, stone weight, TSS and ascorbic acid. Path analysis studies showed that highest positive and direct effect was observed in pulp: stone ratio, seed weight and fruit length. Additionally, mango selection specialized for consumption purpose; table, pickling, or sucking has been determined. Overall, the current study has produced some superior mango selections of indigenous provenance that will serve as a valuable genepool in the future.ThesisItem Open Access Morphological and molecular characterization of genetic diversity in mango germplasm(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2024-02-03) Malik, Shivani; Sharma, Vikas KumarThe present investigation entitled “Morphological and molecular characterization of genetic diversity in mango germplasm” was carried out at College of Horticulture and Forestry Neri, Hamirpur (HP) during 2022 to 2023. Significant diversity was noted among various mango cultivars in terms of several quantitative traits. High heretibility was observed in leaf length, fruit length, pulp weight, peel weight, peel thickness, stonelength, stone width, stone weight, TSS, acidity, reducing sugar, non reducing sugar, ascorbic acid and total carotenoids. Pulp weight was recorded to have highest phenotypic and genotypic coefficients of variation. Genetic gain was recorded to be highest in pulp weight, total carotenoids and fruit weight at ripening. Genetic and phenotypic correlation studies showed that fruit weight had positive and significant correlation with pulp weight, peel weight, seed weight, seed width, seed length, ascorbic acid, fruit weight, fruit length, TSS, total sugar and non-reducing sugar. Fruit weight had negative and significant correlation with peel thickness and petiole length. The path coefficient analysis has shown that the fruit weight had maximum positive direct effect on pulp weight followed by non-reducing sugar and maximum negative direct effect on total sugars followed by seed length. Genetic diversity among the nine mango cultivars was estimated by 20 SSR markers. A total of 271 bands were amplified in all the nine cultivars and 75.64% polymorphism was obtained. Dendrogram showed two main clusters, Cluster A comprised of two cultivarsb namely Pusa Surya and Chausa while Cluster B comprised of rest of the seven cultivars. Further Cluster B was divided into two subclusters. Subcluster B1 comprised of four cultivars and subcluster B2 comprised of three cultivars. The similarity coefficient in nine cultivars ranged from 0.200 to 0.628. Maximum similarity was found between ‘Pusa Shreshth’ and ‘Pusa Arunima’ and minimum similarity was found between ‘Pusa Surya’ and ‘Pusa Shreshth’.ThesisItem Open Access Survey for selection of elite genotype(s) of Jamun (Syzygium cumini L.

The experiment was laid out in factorial randomized block design with four replications. The investigation comprised of five treatments involving treatment T1 (2.5 cm Heading back), T2 (5cm Heading back),T3 (10 cm Heading back),T4 (15 cm Heading back), T5 (control). In general the higher intensity of pruning enhanced vegetative growth that observed in treatment T4 (64.79 cm), stem girth (2.85 cm), tree-spread (41.33 cm), number of new shoots (5.50). All flowering characteristics including (time of bud break, time of first flowering, fruit set and full bloom) were recorded earlier in treatment T3. Lower intensity of pruning T2 (5 cm Heading Back) & T1 (2.5 cm Heading Back) resulted in lesser vegetative growth as compared to 15 cm Heading Back but there was reduction in fruit yield and quality as well. Maximum fruit yield (14.16 kg) and fruit quality that includes TSS (8.73 °B), reducing sugar (3.68 %) and total sugar (6.23 %) was recorded in treatment T4.Therefore (15 cm Heading Back) can be regarded as the best treatment in the present study.ThesisItem Open Access Studies on the effect of integrated nutrient management practices on cropping and fruit quality of mrig-bahar crop of guava (Psidium guajava L.) under high density plantation(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2024-01-12) Bhatia, Ritika; Banyal, Sanjeev K.The “studies on the effect of integrated nutrient management practices oncropping and fruit quality of mrig-bahar crop of guava (Psidium guajava L.) under high density plantation” were carried out during 2022-23 on 5 years old guava plants (cv. L-49) at experimental farm of the Department of Fruit Science, College of Horticulture and Forestry, Neri, Hamirpur (HP). The experimental study comprised of five treatments which involved combined application of vermicompost and inorganic fertilizers along with biofertilizers. During the present studies, it was perceived that the vegetative growth parameters, flowering and fruiting parameters, yield and the leaf and soil nutrient status were significantly enhanced with the integrated nutrient management practices over control. The highest increase in the plant height (74.00 cm), tree spread in N-S direction (89.40 cm) and E-W direction (91.70 cm), trunk girth (1.25 cm), number of flowers per branch (10.20), fruit set (71.84 %), fruit retention (65.46 %) and yield (8.25 kg/tree) were recorded with the application of 80 % RDF + 4 kg vermicompost + NBF consortium (T1) which was closely followed by the application of 60 % RDF + 8 kg vermicompost + NBF consortium (T2). The biochemical quality parameters like TSS, pectin content, total sugars, reducing sugars, non-reducing sugars were highest with the application of 60 % RDF + 8kg vermicompost + NBF consortium (T2) and were minimum in control (100 % RDF). The highest soil nitrogen content (281.00 kg ha-1), phosphorous content (21.50 kg ha-1) and potassium content (258.88 kg ha-1) were recorded in treatment T1 with the application of 80 % RDF + 4 kg vermicompost + NBF consortium whereas the total culturable count was highest in treatment T4 (20 % RDF + 15 kg vermicompost + NBF consortium). Lowest soil NPK and total culturable count were recorded in control (T5-100 % RDF).
