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.

    Exploring lactic acid bacteria for probiotic attributes from fermented foods in low hill region of Himachal Pradesh
    (College of Horticulture and Forestry, Dr YSP UHF, Neri, Hamirpur (H.P.), 2021-01-27) Shivani; Saini, Raj
    The present investigation entitled “Exploring lactic acid bacteria for probiotic attributes from fermented foods in low hill region of Himachal Pradesh” was carried out to isolate lactic acid bacteria (LAB) from diverse local fermented food samples that included lassi, dahi, and batter or dough of jalebi, bhature, babroo, badi and seera, as well as raw milk on deMan, Rogosa and Sharpe (MRS) agar and assess them for probiotic attributes. Thirteen out of total forty two bacterial isolates obtained from different foods, were presumed as LAB isolates on the basis of catalase test, Gram’s reaction and bacterial growth on MRS agar with bromocresol purple. They were screened initially for acid tolerance at pH 2 and pH 3. The LAB isolates showed good tolerance to pH 3 with a cell viability of 4.49±0.09 to 10.37±0.03 log cfu/ml after 180 min of incubation at 370C. Only some isolates could tolerate pH 2 for 120 min. Among the thirteen LAB isolates, seven isolates (NM2, NL1, NL2, JN1, JN2, NB2 and BS3) with good acidity tolerance (43.5 to 97.76% cell survival at pH 3 for 3 h) were further evaluated for growth at pH 9, bile tolerance, antimicrobial activity, safety assessment and functional probiotic attributes. The LAB well tolerated the alkaline conditions with high cell viability (10.06±0.05 to 11.14±0.03 log cfu/ml) at pH 9 after 8 h of incubation. The isolates showed resistance to 0.3% bile salt concentration with 39.18 to 88.36% cell survival for 8 h. The isolates variably displayed fair to good inhibition of pathogenic bacteria Bacillus cereus and Pseudomonas aeruginosa. The lactic acid produced by the LAB isolates ranged from 6.33±0.14 to 7.86±0.10 g/l at 370C after 24 h, and the maximum was observed for BS3. All isolates displayed exopolysaccharide production. Their safety assessment revealed that most LAB isolates exhibited antibiotic susceptibility to ampicillin, chloramphenicol, vancomycin, tetracycline and gentamicin; all were non-haemolytic and did not show gelatinase activity. The LAB isolates revealed high autoaggregation ability (87.47 to 90.13%), and maximum towards xylene (hydrophicity >40%) was exhibited by only one isolate BS3 (42.90%). The selected LAB were catalase negative, Gram positive cocci or coccobacilli, and differed in their biochemical characteristics. Based on the various probiotic attributes displayed by the LAB isolates, only one isolate BS3 from badi with overall good probiotic attributes was selected for 16S rRNA gene sequencing and identified as Enterococcus faecium strain BS3. The study concludes that local fermented foods are a good source of lactic acid bacteria with promising probiotic traits. However, additional tests are required to meet the safety and functionality criteria as well as the technological usefulness of the isolates in the production of probiotic foods.

    Ecofriendly management of Fusarium wilt of pea (Pisum sativum L.)
    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-10-19) Shivani; Sharma, Monica
    The pathogen causing wilt of pea was isolated and identified as Fusarium oxysporum f. sp. pisi on the basis of cultural, morphological and molecular characters. Amplification of DNA region coding for internal transcribed spacer (ITS) region with primer pair ITS1 and ITS4 gave a single band of approximately 700 bp on gel electrophoresis. In pathogenicity test, typical symptoms appeared after 22 days of inoculation of F. oxysporum f. sp. pisi on pea plants. Six isolates (F1, F2, F3, F4, F5 and F6) of Fusarium spp. from different hosts and locations were characterized on the basis of morphological, cultural and molecular characters. Among aqueous biopesticides, maximum mycelial growth inhibition (50.00%) was observed by using extract of Cannabis sativus at 40 per cent concentration. Cow urine alone resulted in maximum inhibition in mycelial growth of fungus at all tested concentrations i.e., 5, 10, 15 and 20 per cent whereas in cow urine based biopesticides, effective mycelial growth inhibition (54.36%) was observed with extract of Melia azedarach at 20 per cent concentration. Among the cattle urine biopesticides, M. azedarch (55.80%) resulted maximum mycelial inhibition at 20 per cent. Among ethanol based biopesticides, extract of Tagetes erecta resulted in maximum mycelial inhibition (89.87%) at 4 per cent concentration. Evaluation of biopesticides for management of Fusarium wilt disease of pea showed that aqueous extract of Eucalyptus citriodora resulted in minimum disease incidence (58.33%). Among the cow urine and cattle urine biopesticide cow urine extract of M. azedarach resulted in maximum disease incidence reduction (50.00%) whereas, in cattle urine extract of Ocimum tenuiflorum (42.12%) resulted maximum disease incidence reduction. The ethanol based biopesticide of Lantana camara (43.01%) resulted maximum disease incidence reduction. Among biocontrol agents, Pseudomonas flourescens (NE-32-strain) resulted in maximum mycelial growth inhibition (72.96%). Among biocontrol agents, minimum disease incidence was resulted with Trichoderma koningii (JA-strain) (50.33%) compared to control.

    Studies on the effect of organic nutrient sources on soil properties and yield of okra [Abelmoschus esculentus (L.) Moench] in sub- tropics of Himachal Pradesh
    (College of Horticulture and Forestry Neri, Hamirpur (H.P.), 2021-10-26) Shivani; Sharma, Rakesh
    A field experiment entitled "Studies on the effect of organic nutrient sources on soil properties and yield of okra [Abelmoschus esculentus (L.) Moench] in sub-tropics of Himachal Pradesh" was conducted during kharif 2020 at experimental farm of Department of Soil Science and Water Management, College of Horticulture and Forestry, Neri (Hamirpur), Dr. YSP University of Horticulture and Forestry, Nauni, H.P. in a randomised block design with nine treatments which were replicated thrice. These nine treatments were: T1= sole application of jeevamrit @ 5 per cent at weekly interval, T2= FYM @ 10 t/ha + R.D.F (recommended practice), T3= FYM @ 10 t/ha + jeevamrit @ 5 per cent at weekly interval, T4= FYM @ 10 t/ha + jeevamrit @ 5 per cent at fortnight interval, T5= vermicompost @ 2.5 t/ha + R.D.F, T6= vermicompost @ 2.5 t/ha + jeevamrit @ 5 per cent at weekly interval, T7= vermicompost @ 2.5 t/ha + jeevamrit @ 5 per cent at fortnight interval, T8= jeevamrit @ 5 per cent + ghanjeevamrit at fortnight interval and T9= 100 per cent R.D.F where, R.D.F was recommended dose of fertilizers (NPK = 75:50:55 kg ha-1). Treatment T6 recorded increase in growth, yield and quality attributes of okra as compared to recommended practice (T2). Also, T6 recorded higher B: C ratio. Further, soil bulk density, particle density, porosity, soil pH and EC did not differ significantly with the application of different organic nutrients sources. Whereas, water holding capacity, organic carbon content, available N, P, K, S, DTPA extractable micronutrients viz., Fe, Cu, Zn and Mn and biological indicator of soil such as total viable microbial population, microbial biomass carbon and microbial biomass nitrogen were recorded higher in treatment T3 followed by T6. Yield showed highly significant and positive relationship with plant height and number of leaves indicated their importance in influencing yield. Also, yield exhibited significant and positive relationship with soil organic carbon, total viable microbial population, microbial biomass carbon and microbial biomass nitrogen which indicated their importance for nutrient turn-over and their availability to plants. The study revealed that application of jeevamrit @ 5 per cent at weekly interval in combination with vermicompost and FYM showed better results over combined application of R.D.F with vermicompost and FYM.
