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.

    EVALUATION OF SOLAR DRYER FOR DRYING OF WILD FRUITS GROWN IN HIMACHAL PRADESH
    (UHF,NAUNI, 2017-11) ANKUSH; AGGARWAL, R.K.
    ABSTRACT The present investigation entitled “Evaluation of solar dryer for drying of wild fruits grown in Himachal Pradesh” was carried out at the experimental farm of Department of Environmental science, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2016-2017. Wild ber (Zizyphus mauriatiana L.), wild anola (Phyllanthus emblica L.) and wild bael (Aegle marmelos L. Corr.) were selected for present study and pre treated for drying. There were five treatments and three replications viz. untreated fruits dried in open sun (T1), treated fruits dried in open sun (T2), treated fruits dried in indirect solar dryer (T3), untreated fruits dried in indirect solar dryer (T4) and treated fruits dried in mechanical cabinet dryer (T5). Drying modes like mechanical cabinet drier, indirect solar drier and open sun were compared on the basis of various physicochemical and sensory quality characteristics. The ber, aonla flakes and bael slices from the best drying mode (mechanical cabinet drier; 60 ± 20C) possessing maximum desirable physico-chemical characteristics considered for shelf life analysis. Average drying time in open sun was 237.00 hours, 134.10 hours in solar dryer, and 22.23 hours in mechanical cabinet dryer. Average drying rate in open sun was 0.35 gram per hour, 0.63 gram per hour in solar dryer and 4.32 gram per hour in mechanical cabinet dryer. Average water activity of dried fruits was 0.364 in open sun, 0.327 in solar dryer and 0.276 in mechanical cabinet dryer. Cost of drying was minimum in indirect solar dryer for all fruits as compared to mechanical cabinet dryer. Treated wild ber, wild aonla and wild bael slices dried in indirect solar dryer (T3) were rated best among all drying modes on the basis of highest sensory scores of colour (8.60), texture (8.40), taste (8.60) and overall acceptability (8.53) for wild ber, colour (8.60), texture (8.40), taste (8.60) and overall acceptability (8.53) for aonla and colour (8.60), texture (8.40), taste (8.60) and overall acceptability (8.53 for wild bael. The fruit dried in indirect solar dryer and control (untreated fruits+ open sun) were packed in polyethylene pouches and stored for three months under ambient storage conditions. The physicochemical characteristics like moisture, total soluble solids, titratable acidity, pH, reducing sugars and total sugars were changed slightly.

    EFFECT OF CHEMICALIZED FARMING ON ENVIRONMENTAL QUALITY IN MID-HILLS OF HIMACHAL PRADESH
    (UHF,NAUNI, 2017-09) POOJA, J; BHARDWAJ, S.K.
    ABSTRACT The present investigation entitled “Effect of chemicalized farming on environmental quality in mid-hills of Himachal Pradesh” was conducted during the year 2016-17 in the Department of Environmental Science, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh. In order to identify the impact of different farming systems on soil and water quality in mid-hills of Solan district of HP four locations: Solan, Kandaghat, Chail and Nauni and six farming systems namely, traditional, organic, polyhouse, vegetable, flower and orchard were selected. Accordingly in total there were six treatments which were replicated four times under Randomized Block Design. In the region farming system wise variation in physico- chemical and microbiological properties indicated that practices under such systems has induced variations, however, found within the permissible range. The bacteria, fungi, and actinomycetes counts under selected systems ranged from 67.25×104 to 92.67×104 , 4.75×103 to 8.17×103 and 29.17×104 to 41.17×104 cfu/g soil and soil microbial biomass ranged from 310.69 to 459.63 μg kg-1 In soil, available NPK ranged from 291.74 to 416.25, 21.64 to 38.41 and 309.08 to 408.23 kg ha-1, respectively, and exchangeable Ca, Mg, and available S ranged from 3.71 to 7.40 cmol (p+)/kg, 1.35 to 2.24 cmol (p+)/kg and 42.07 to 56.60 kg ha-1 under different farming systems. The farming systems of mid hills has been noticed to enhance the build up of toxic metals such as such as Fe, Mn, Cd, Cr, Cu and Pb in the soil above the permissible limits as prescribed by BSI (1992) and WHO (1993), except for Zn. The farming systems like flower, traditional, vegetable and orchard represented poor soil quality with respective values of 0.44, 0.45, 0.47, 0.48 and organic, and polyhouse were found be in medium range with the values of 0.60 and 0.58. The pH and EC of the water ranged from 7.63 to 7.76 and 0.24 to 0.40 dSm-1, respectively, and was within the normal range. The BOD and COD of water ranged from 0.78 to 1.63 and 17.50 to 32.53 mg l-1, chloride and nitrate ranged from 14.78 to 27.19 and 4.55 to 11.13 mg l-1, respectively, the values of BOD, chloride and nitrate was within the permissible limit whereas, COD was above the permissible limit as prescribed by BSI and WHO in all the systems except for organic farming. The heavy metals like Cd, Cr and Pb in water sources around the farming systems were within the range of 0.00 to 0.03, 0.05 to 0.40 and 0.03 to 0.14 mg l-1 which were above the permissible limits as prescribed by BSI and WHO, except for Zn and Fe. Therefore, on the basis of the present study it is concluded that in mid-hills of Solan district of HP the different farming systems has started impacting the soil and water quality and hence necessary measures need to be taken in time.
