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 Impact of Climate Change on Vegetable Crop Production in Mid Hills of Himachal Pradesh
    (YSPU, 2016) Meena Kumari; Verma, Subhash Chander
    The present investigations entitled “Studies on Impact of Climate Change on Vegetable Crop Production in Mid Hills of Himachal Pradesh” was conducted during the years 2014 and 2015 at the Research Farm of Department of Environmental Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan, H.P. The study revealed that higher plant height (11.04cm) at maturity, pollen viability (79.90%) was recorded in bell pepper at elevated CO2 . Elevated CO 2 and temperature resulted minimum days (104.17days)to first picking of bell pepper fruits. Bell pepper under elevated CO 2recorded maximum fruit size (40.19cm 2 ), average fruit weight (63.06g/fruit), plant fresh weight (460.15g/plant), dry weight (107.19 g/plant), ash content (23.68%), total phenols (39g/100g), calcium (0.46%) than ambient CO 2 and temperatureand natural condition. Elevated CO2 and temperature recorded minimum chlorophyll (1708.71mg/kg), nitrogen (4.39%), phosphorus (0.25%), potassium (4.48%) and magnesium(0.36 %) as compared to ambient CO 2 and temperature and natural condition. Maximum S. lituralarval period (19.92days), larval weight (0.51g), fecal matter (0.42g), RCR (64.86mg.d-1 ), AD (84.24%), leaf damage (14.52%) and minimum ECI (36.14%) and ECD (43.23%) was under elevated CO 2 . Maximum number aphids (17.08 aphids/plant), maximum Phytophthora blight incidence (22.71%), Cercospora leaf spot severity (15.88%) was recorded under elevated CO2 and temperature. The plant fresh weight (+29.63 %) and plant biomass(+37.53%), average fruit weight (+ 23.63%) and fruit yield (+17.01 %) was higher in Solan Bharpur as compared to California Wonder (fresh weight :+22.48%;biomass:+33.14%;fruit eight:+15.75% and fruit yield: +11.97%) under elevated CO2 over ambient CO2 and temperature. Plants of pea exhibited, higher plant height (97.82 cm) at maturity, pollen viability (78.42 %), leaf water content (89.28 %), leaf area (71.47 cm 2 ), number of pods (45.50 pods/plant), pod length (10.14 cm) pod girth (13.75 mm), highest pod yield (304.53 q/ha), plant dry weight (36.17 g/plant), ash content (11.54 %) and calcium (0.56%) in pea under elevated CO2. Pea leaf miner infestation (14.87 %) was higher under natural condition and lowest under elevated CO 2 (11.97 %). Maximum severity of powdery mildew in pea plants was under elevated CO2 and temperature (16.33 %) and minimum in natural condition (2.96 %). Maximum Fusarism wilt incidence in pea was in elevated CO2 (3.53 %) and minimum in natural condition (2.18 %). The plant fresh weight, plant biomass and ash content increased to +19.74 per cent, +38.21 per cent and 38.20 per cent, respectively in PB - 89 under elevated CO2 in mparison to Azad P - 1 (fresh weight: +18.87 %; biomass: +32.61% and ash content: +37.57%). Number of pods/plant, number of grains/pod, average pod weight and pod yield increased to + 19.65 per cent, + 28.93 per cent, + 44.65 per cent and +36.23 per cent, respectively, in PB – 89 under elevated CO2 as compared to Azad P-1(pods/plant: +17.71 %; number of grains/pod: + 26.92 %; average pod weight: + 35.48 %; pod yield: +31.22 %) . Thus elevated CO 2 worked positively and increased productivity of both crops, however, the positive effects of elevated CO2were negated by interactive effects of elevated CO2 and temperature in the both crops. In case of bell pepper cultivar Solan Bharpur and pea cultivar PB-89 were more adaptable to climate change as compared to California Wonder of bell pepper and Azad P-1of pea, respectively. Hence, Solan Bharpur of bell pepper and PB-89 of pea were better performing cultivars under changing climate in mid hill conditions of Himachal Pradesh.

    STUDIES ON ZOOPHYTOPHAGY OF Nesidiocoris tenuis (REUTER) (HEMIPTERA: MIRIDAE) ON TOMATO
    (2016) JAYPRAKASH, GAVKARE OMKAR; SHARMA, P.L.
    ABSTRACT The present investigation entitled “Studies on zoophytophagy of Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) on tomato” was carried out under laboratory and glasshouse conditions at Department of Entomology, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) India during 2013-16. Developmental biology of the bug was significantly influenced by the rearing temperature. Temperature between 20 and 30oC has been found to be ideal for the growth and development of the bug. Low temperature (15°C or below), however, had adverse effect on the growth and development of the bug. N. tenuis required 500 degree-days with developmental threshold of 9°C to complete the development from egg to adult. N. tenuis has been found to be an efficient predator of the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) and the two spotted spider mite, Tetranychus urticae Koch. The bug exhibited Holling’s Type II functional response to T. urticae and showed mutual interference among predator individuals when their density is 2 or more predator per arena of 200 mites. Under glasshouse conditions, N. tenuis at densities of 4-32 bugs/ plant proved effective for the control of T. vaporariorum and T. urticae. As far as the damage potential of the bug on tomato is concerned, N. tenuis caused necrotic rings on leaves and shoots, flower abortion and reduction in fruits per plants, though, the reduction was significant only at bug density beyond 24 nymphs per plant or 16 bugs per plant. The damage potential was further reduced in the presence of the prey i.e. T. vaporariorum and T. urticae. N. tenuis can be successfully multiplied on tomato seedling infested with T. urticae and a bug density of 6/seedling was optimum.
