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.

    EFFECT OF WATER STRESS ON SEED YIELD AND QUALITY OF Coriandrum sativum Linn.
    (UHF,NAUNI, 2014) THAKUR, PRIYANKA; THAKUR, ANJU
    ABSTRACT The present investigation entitled, “Effect of water stress on seed yield and quality of Coriandrum sativum Linn.” was carried out at the experimental farm and laboratory of Department of Seed Science and Technology (SST), Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during 2012 - 2013. The objective of the experiment was to evaluate the effects of various magnitudes of water stress i.e. 25, 50 and 75% deficit on seed yield and quality of coriander. In addition, effect of water stress on underlying physiological and biochemical changes was also studied. Water stress conditions imposed at flower forming phase for 15 days resulted in significant reduction in plant growth viz. shoot height, branch number, umbel number , umbellet number , fresh and dry weight of rootand shoot both and root-shoot ratio. Yield characteristics i.e. seed number and seed weight showed substantial reduction as compared to unstressed plants. The maximum reduction in growth and yield attributes was registered for plants subjected to 75% water deficit. Whereas, growth and yield was not substantially affected at 25% water deficit. Quality of seeds harvested from stressed plants was lower in terms of germination percent, mean germination time and seedling vigour. The results of the study helped in assessing the yield losses when water availability is limited and also to find the tolerance of coriander to water stress. Physiological indices viz. Water potential, canopy temperature depression, quantum efficiency of PS-II and enzymes namely catalase and dehydrogenase showed inhibition under all water stressed regimes with maximum inhibition under 75% water stress. Osmoregulating substances i.e. total free amino acid, total free proline and total soluble sugars showed increased accumulation with increasing magnitude of water stress which helped in enhancing drought tolerance at mild water stress. The studies indicated that water stress imposed at flowering stage reduced seed yield substantially therefore the crop must not suffer from water stress of higher magnitude during and after flowering inorder to sustain yield.

    EVALUATION OF PLANT PRODUCTS AND OTHER NOVEL METHODS FOR THE MANAGEMENT OF FRUIT FLY Bactrocera spp. INFESTING CUCUMBER
    (2012) THAKUR, PRIYANKA; GUPTA, DIVENDER
    ABSTRACT The present studies on “Evaluation of plant products and other novel methods for the management of fruit fly, Bactrocera spp. infesting cucumber” were conducted in laboratory as well as field conditions. In laboratory studies, different concentration of azadirachtin (Econeem 10,000 ppm) (0.005, 0.01 and 0.015%), neem oil (1, 2 and 3%), Daman 1% WP (B. bassiana) (0.1, 0.5 and 1%), pongamia oil (1, 2 and 3%) and clay (6, 8 and 10%) were evaluated for oviposition deterrence. Azadirachtin (0.015%) followed by neem oil (3%), Daman (1%) and clay (10%) proved effective with 89.09, 80.24, 83.40 and 89.29 per cent oviposition deterrence over control, respectively. Cucumber slices when dipped in pongamia oil (1, 2 and 3%) caused degradation in the tissues due to which further studies could not be carried out under laboratory conditions. Egg hatchability in different treatments was worked out. Azadirachtin (0.015%), neem oil (3%), Daman (1%) and clay (10%) resulted in minimum 32.75, 59.47, 39.79 and 61.00 per cent egg hatch with 2.5, 1.5, 2.2 and 1.5 times decrease over control. Best treatments obtained in the laboratory studies were also evaluated in the field for their efficacy to check fruit fly infestation. Azadirachtin @ 0.01 per cent and Daman @ 1 per cent proved equally effective in checking fruit fly infestation with 31.20 and 37.74 per cent followed by neem oil (3%) where 40.78 per cent fruits were found infested. Pongamia oil (2 and 3%) evaluated in the field resulted in 46.12 and 48.12 per cent fruit infestation, respectively. In clay treatments, 44.98 and 43.03 per cent fruit infestation was recorded at 8 and 10 per cent concentration, respectively. All the treatments were superior over control (65.19%). The highest yield (3.1 kg/plot) was obtained in 0.01 per cent azadirachtin treated plots followed by neem oil (2.7 kg/plot) applied @ 3 per cent and Daman 1% WP (2.5 kg/plot) @ 1 per cent concentration. In pongamia oil and clay treatments the yield ranged between 2.2 to 2.6 kg/plot in comparison to 1.8 kg/plot in control. The yields/plot were inversely proportional to fruit infestation. In field evaluation, in all the treatments no phytotoxicity symptoms were observed. Based on these studies, azadirachtin (Econeem 10,000 ppm) and Daman can be included in the module for integrated pest management against fruit flies. Clay needs to be further evaluated by using commercial formulation (Surround 50 WP) which has better adherence to surface and hence may prove better.

    EVALUATION OF SOME TOMATO GENOTYPES FOR THEIR REACTION AGAINST FRUIT BORER Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) IN MID HILLS OF HIMACHAL PRADESH
    (2015) THAKUR, PRIYANKA; RANA, R.S.
    ABSTRACT Eight tomato varieties viz. Palam Pink, Solan Vajar, Solan Lalima, Naveen 2000+, Yash, Rakshita, Red Gold and Heem Sohna were evaluated for their reaction to the tomato fruit borer, Helicoverpa armigera (Hubner). Maximum infestation of fruit borer was recorded in the month of May. Egg and larval count of H. armigera was made on these varieties. The per cent fruit infestation in different tomato varieties was evaluated on the basis of number of damaged fruits and this was correlated with various parameters like fruit length, fruit diameter, fruit shape, fruit pericarp thickness, fruit weight, fruit yield, plant height, stem diameter, leaf area, number of leaf hairs, titrable acidity, reducing sugars, total sugars, total phenols, leaf macro and micro nutrients (nitrogen, phosphorous, potassium, magnesium, iron, copper, manganese and zinc). None of the varieties were found to be immune to fruit borer attack but considerable variation of infestation in different varieties was observed. The percent fruit damage varied from 15.57 to 45.30 per cent recording the highest fruit infestation in ‘Red Gold’ which was significantly at par with ‘Heem Sohna’, ‘Yash’ and ‘Palam Pink’ while the lowest fruit infestation was observed in ‘Solan Lalima’ which was at par with ‘Solan Vajar’, ‘Naveen 2000+’ and ‘Rakshita’. Fruit diameter, leaf area, leaf hairs, nitrogen, potassium, magnesium, iron and manganese content were found to be positively correlated with per cent fruit infestation while fruit length, fruit shape index, fruit pericarp thickness, total sugars, total phenols, phosphorous and zinc content were found to be negatively correlated with the attack of the fruit borer. However on the basis of maximum yield per plant present studies conclude that Naveen 2000+ which also was categorized as less susceptible was found to be the most suitable variety.
