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.

    BIOEFFICACY AND PERSISTENCE OF COMBI PRODUCT FLUBENDIAMIDE AND DELTAMETHRIN AGAINST MAJOR INSECT PESTS OF TOMATO
    (UHF,NAUNI, 2019-11) KUMAR, ANIL; DUBEY, J K
    ABSTRACT The field experiment to evaluate “Bioefficacy and persistence of a combi product flubendiamide and deltamethrin against major insect pests of tomato” was conducted during 2018 in the Entomology Farm Dr Yashwant Singh Parmar University Nauni, Solan. Bioefficacy studies revealed that all the insecticide treatments were significantly superior over control. Amongst all treatments, Fame Quick (flubendiamide 8.33 + deltamethrin 5.56 w/w) @ 72+48 g a.i./ha was found most effective in reducing larval population in fruit borer as well as in tomato pinworm followed by its single dose which were on a par with each other. Whereas, deltamethrin @ 24 g a.i./ha was found to be least effective treatment. Fruit damage of 4.11 and 6.67 per cent was recorded in H. armigera and Tuta absoluta, respectively due to Fame Quick (flubendiamide 8.33 + deltamethrin 5.56 w/w) @ 72+48 g a.i./ha. Initial deposits of 0.316 mg/kg of flubendiamide at 36 g a.i./ha due to application of combi product at X dose level of flubendiamide+deltamethrin (Fame Quick) dissipated to 0.218 and 0.110 mg/kg at 1 and 3 days of application whereas, at 2X dose level of flubendiamide at 72 g a.i./ha due to the application of combi product flubendiamide+deltamethrin (Fame Quick) the initial deposits of 0.554 dissipated to 0.423, 0.223 and 0.124 mg/kg at 1, 3 and 5 days of application. Initial deposits of 0.307 mg/kg of deltamethrin at 24 g a.i./ha due to application of combi product at X dose level of flubendiamide+deltamethrin (Fame Quick) dissipated to 0.151 and 0.073 mg/kg at 1 and 3 days of whereas, at 2X dose level of deltamethrin 48 g a.i./ha due to the application of combi product flubendiamide+deltamethrin (Fame Quick) the initial deposits 0.636 mg/kg dissipated to 0.299, 0.145 and 0.074 mg/kg after 1,3 and 5 days of spray application. While, no residues of flubendiamide and deltamethrin were detected in any tomato field soil sample at 20 days of interval in both X and 2X dose level due to application of combi product flubendiamide+ deltamethrin (Fame Quick). RL50 values observed to be 2.0 and 2.3 days in flubendiamide and in deltamethrin the half-life is of 1.5 and 1.7 days at X and 2X dose of flubendiamide+deltamethrin (Fame Quick). Hence, a safe waiting period 8 days can be recommended for a combi product flubendiamide + deltamethrin as a Fame Quick.

    POLLINATION AND FRUIT SET STUDIES IN CUCUMBER (Cucumis sativus L.)
    (UHF,NAUNI, 2017) VERMA, NEHA; RAMESH, KUMAR
    ABSTRACT The present investigations entitled “Pollination and fruit set studies in cucumber (Cucumis sativus L.)” were carried out at the Experimental Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif, 2016 to gather information on use of chemicals (Gibberellic acid, Silver nitrate and Silver thiosulphate) in modification of sex expression in gynoecious varieties (GYNO-1 and GYNO-2) of cucumber, floral biology and also to assess the efficiency of different system of pollination on fruit and seed setting and their characteristics in monoecious (K-75 and UHF-CUC-101) and gynoecious (GYNO-1 and GYNO-2) varieties. The experiment was laid out in a RCBD with three replications. Use of chemical in modification of sex expression, floral biology, fruit and seed setting studies were assessed through factorial analysis in randomized block design and completely randomized design proposed by Panse and Sukhatme (2000). The observations were recorded on use of chemicals in modification of sex expression in gynoecious lines (induction of male flowers), pollination studies, time of anthesis, dehiscence, pollen viability(%), stigma receptivity, node number bearing first female flower, average fruit weight (g), number of seeds per fruit and thousand seed weight (g). Amongst the various chemical used, silver thiosulphate was found best for the induction of staminate flower in gynoecious cucumber at 500ppm. Anthesis started at 6AM and completed by 8AM with the maximum anthesis between 6AM to 7AM in monoecious varieties whereas, in gynoecious varieties it was maximum upto 6:00AM in both open and controlled conditions and similar pattern was observed for dehiscence. Dehiscence occurs soon after anthesis. Maximum pollen viability was recorded on the day of anthesis and viability of pollen under refrigerated condition does not decreased as rapidly as it was under room temperature condition with the duration of pollen storage. Maximum stigma receptivity was noticed at anthesis time and pollination during this interval recorded maximum fruit set. A higher fruit set was observed in case of open pollination as compared to self pollination method. Gynoecious lines were earlier in flowering and fruiting than monoecious varieties. Open pollination had better effect on fruit and seed characteristics as compared to self pollination.
