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 SEASONAL INCIDENCE OF INSECT PESTS OF TOMATO AND ECO-FRIENDLY MANAGEMENT OF Tuta absoluta (Meyrick)
    (UHF,NAUNI, 2021-07) MONIKA; MOHINDER SINGH
    ABSTRACT The present investigation “Studies on seasonal incidence of insect pests of tomato and ecofriendly management of Tuta absoluta (Meyrick)” was conducted during 2019 and 2020. During the surveys, tomato pinworm (Tuta absoluta), whitefly (Trialeurodes vaporariorum), aphids (Myzus persicae and Macrosiphum euphorbiae), serpentine leaf miner (Liriomyzia trifolii), and fruit borer (Helicoverpa armigera) were recorded during both years. The aphid species M. persicae was recorded in low hills, whereas, M. euphorbiae was found to infest tomato in mid hills. Higher pest infestations were recorded on tomato in mid hills as compared to low hills of Himachal Pradesh. Coccinellids and spiders were recorded major natural enemies in tomato crop. The peak populations of these insect pests and natural enemies were observed between 2nd fortnight of June and 1st fortnight of July. Positive correlation of whitefly population was found with minimum temperature (r = 0.473), while maximum temperature exhibited positive and significant correlation (r = 0.473, r = 0.605) with aphid population and serpentine leaf miner infestation. The fruit borer population showed positive and significant correlation with maximum temperature (r = 0.483), while it was negative with minimum temperature (r = - 0.500) and relative humidity (r = - 0.721). The number of T. absoluta mines per leaf was positively and significantly correlated with minimum temperature (r = 0.487, r = 0.470 in 2019 & 2020, respectively). Out of 15 tomato genotypes screened against T. absoluta , 4 genotypes namely, BWR - 1, BWR -5, EC - 526146 and TM - 7 were found resistant, whereas 8 genotypes including CLN - 2116, EC - 5863, Solan lalima, B -1. TH - 19, FT - 5, TM - 23 and EC - 521041 were partially resistant and 3 genotypes namely, CLN - 2070, TH - 05 and TM - 15 were susceptible. Three sprays of spinosad or Coragen or one spray of econeem and two sprays of spinosad were found effective against whiteflies and aphids, whereas against tomato fruit borer, tomato pinworm and serpentine leaf miner, Coragen gave the best results, followed by spinosad.

    STUDIES ON APPLE POLLEN FORAGING PREFERENCE IN Apis mellifera L.
    (UHF,NAUNI, 2017-10) MONIKA; SHARMA, HARISH KUMAR
    ABSTRACT The present investigations “Studies on apple pollen foraging preference in Apis mellifera L.” were carried out in the Department of Entomology, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). Significant variations in A. mellifera stock have been found in various colony parameters like colony strength (4 to 7.67 bee frames), brood area (515.67 to 1883.33 cm2), pollen stores (20.67 to 366 cm2) and honey stores 50 to 1000g. The average colony strength was maximum (7.67 bee frames) in colony number C-3 and C-32. On the basis of ranking obtained by different colonies with respect to colony strength, brood area and honey stores, 10 colonies with high pollen hoarding and 10 with low pollen hoarding tendency were selected. The data on performance of high and low pollen hoarding colonies revealed significant differences with respect to different colony parameters. Ranking obtained by different colonies with respect to colony strength, brood area, pollen stores, honey stores, pollen stores and hygienic behaviour were scored as per their performance. The main criteria for selecting colonies with high pollen hoarding and low pollen hoarding tendency was average pollen stores. The three high pollen hoarding colonies (H-4, H-5 and H-9) were those which scored 3 to 4.50, whereas low pollen hoarding colonies (L-4, L-6 and L9) scored 4 to 4.50 for average pollen stores and bee foragers. The low pollen hoarding & high pollen hoarding colonies also showed significant seasonal variations with respect to various colonies characteristics. Number of incoming bees with pollen loads at hive entrance was significantly more (51.94 bees per minute) in high pollen hoarding honeybee colonies as compared to low pollen hoarding colonies (42.82 bees per minute). Apple pollen preference in colony number G-2 from general stock showed highest preference for apple pollen foraging with 18.78 per cent of apple pollen loads. Colony H-4 recorded minimum percentage of apple pollen load. Out of nine, 7 colonies collected significantly same percentage of apple pollen. These studies suggest that selection efforts for bees with the preference for apple pollen could be combined with selection for pollen hoarding to get a strain of honeybee with higher preference for apple pollen foraging.

    STUDIES ON ECO-FRIENDLY METHODES OF NEMATODE MANAGEMENT IN OKRA, Abelmoschus esculentus (L.) MOENCH
    (2015) MONIKA; KHANNA, ANJU SUDHAKAR
    ABSTRACT The present investigation entitled ‘Studies on eco-friendly methods of nematode management in okra (Abelmoschus esculentus L. Moench)’ was conducted to exploit management practices other than chemical control in against Meloidogyne incognita highly susceptible okra crop. In order to economize the management expenditure against plant parasitic nematodes, okra seeds were coated/dipped in botanical formulations viz., max raze, max cannon and bacterial bio agent Pseudomonas fluorescens in comparison to dips in carbosulfan . Improved plant growth parameters, fruit yields and reduced galling of roots were recorded in all the treatments as compared to untreated control. A negative correlation between root gall index and fruit yield indicated that root galling caused by M. incognita eventually reduced the okra fruit yields. Among the soil application of shade dried leaf powders of certain plants known to have nemato toxic principles viz., Lantana camara, Parthenium hysterophorus, Ricinus communis and Tagetes patula, minimum root galling and juvenile count and significantly improved fruit yields were attained in plants raised in lantana and castor treated soil. Parthenium and marigold on the other hand were not as effective among the oil cake amendments, neem cake was found to be the best followed by mustard cake considering their effect on root galling and quantum of fruit production. Ground nut cake though, least effective among the three test oil cakes yielded significantly improved vegetative growth and fruit yield as compared to control. In addition, three species each of Trichoderma viz., T. viride, T. polysporum , T. hamatum, and Pseudomonas viz., P. fluoresccens, P. putida and P. aeruginosa were assessed for their efficacy against M. incognita in a pot experiment. Fruit yield increased significantly over untreated control in all the treatments. The highest quantum of fruits and minimum root galling were observed in okra plants growing in soils treated with T. viride and P. fluorescens. However, yields produced by plants raised in P. fluorescens applied soils was statistically similar to those treated with T. polysprum T. hamatum and P. putida. Pseudomonas aeruginosa was found to be least effective among various tested bioagents.
