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.

    PERSISTENCE OF IMIDACLOPRID, LAMBDACYHALOTHRIN AND SPIROMESIFEN ON CAULIFLOWER
    (UHF,NAUNI, 2018-07-04) NIDHI; KATNA, SAPNA
    ABSTRACT The present investigations on “Persistence of imidacloprid, lambda-cyhalothrin and spiromesifen on cauliflower” was carried out during 2016-2017 in the department of Entomology, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan. The objectives of the study were to evaluate the persistence of imidacloprid, lambda-cyhalothrin and spiromesifen in/on cauliflower curds and the cropped soil. The effect of decontamination methods in dislodging the insecticide residues from cauliflower was also studied. The study was conducted using Confidor 17.8 SL 140 and 280 mL ha-1), Reeva 5 EC (300 and 600 mL ha-1) and Oberon 240 SC (419 and 838 mL ha-1) at single and double dose, respectively. The persistence study on cauliflower curds recorded initial deposits due to single and double dose of imidacloprid (25 and 50 g a.i. ha-1) as 0.488 and 0.912 mg kg-1, lambda-cyhalothrin (15 and 30 g a.i. ha-1) as 0.303 and 0.610 mg kg-1 and spiromesifen (96 and 192 g a.i. ha-1) as 0.960 and 2.083 mg kg-1. Imidacloprid, lambda-cyhalothrin and spiromesifen residues persisted in cauliflower curds upto 7 and 10 days at single and double dose, respectively. The residues of imidacloprid, lambda-cyhalothrin and spiromesifen in curds reduced to half in less than 4 days. The initial deposits of 0.102, 0.063 and 0.062 mg kg-1 at single dose and 0.191, 0.121 and 0.115 mg kg-1 at double dose were observed for imidacloprid, lambdacyhalothrin and spiromesifen, respectively, in cauliflower cropped soil. Among various decontamination processes, microwave cooking after tap water washing was found most effective which provided up to 90.23 per cent relief followed by open pan cooking after tap water washing (83.41%), saline water washing (50%), lukewarm water washing (41.95%) and tap water washing (26.88%) from the three insecticide residues in cauliflower curds. Safe waiting period of 12.28 days for imidacloprid, 11.33 days for lambda-cyhalothrin and 11.12 days for spiromesifen was suggested to harvest cauliflower safely.

    GENETIC EVALUATION OF TOMATO GENOTYPES UNDER PROTECTED CONDITIONS
    (UHF,NAUNI, 2018-06-22) NIDHI; AMIT, VIKRAM
    ABSTRACT Tomato is one of the most important vegetables consumed in fairly large quantity worldwide. It is one of the premier crop of India generating sizeable employment and is widely grown under protected conditions. The present investigation entitled “Genetic evaluation of tomato genotypes under protected conditions” was carried out at Vegetable Research Farm of the Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) in a naturally ventilated polyhouse during Summer season (July- December) 2017. The experiment was laid out in RCBD with three replications comprising of twenty genotypes of tomato. The observations were recorded on various characters viz., plant height, inter-nodal distance, days to first picking, number of fruits per plant, number of fruits per cluster, average fruit weight (g), yield per plant (kg), yield per square meter (kg), fruit shape index, fruit colour, pericarp thickness, total soluble solids (°brix), whole fruit firmness, lycopene content, ascorbic acid content, harvest duration, number of seeds per fruit and 1000 seed weight (g). A wide range of variability was observed for all the traits. High genetic variability was recorded for lycopene content, whole fruit firmness and yield per plant. High heritability coupled with high genetic gain was recorded for yield per plant, number of fruits per cluster, pericarp thickness, fruit shape index, whole fruit firmness and lycopene content. From the present investigation, it may be inferred that genotypes, UHFT-7-17, UHFT-4-17, UHFT-2-17, UHFT-3-17, UHFT-9-17 and UHFT-5-17 gave higher yield and best quality traits. These genotypes can be evaluated further for their inclusion in hybrid and cultivar development programme for protected structures. Fruit yield per plant was significantly correlated with average fruit weight, number of fruits per plant, harvest duration and pericarp thickness. Path analysis revealed that maximum positive direct effect towards fruit yield per plant was contributed by average fruit weight followed by harvest duration and thousand seed weight.

    STANDARDIZATION OF GROWING MEDIA FOR PRODUCTION OF COLOURED CAPSICUM UNDER POLYHOUSE
    (UHF,NAUNI, 2018-03) NIDHI; SPEHIA, R.S.
    ABSTRACT Capsicum, also popularly called as ‘Simla Mirch’ in India is one of the leading vegetables grown in open conditions as well as protected conditions, because of its economic importance as a high value vegetable crop both in domestic and overseas markets. Capsicum can be grown on a wide variety of soils, but its shallow and fibrous root system is sensitive to water logging and prone to attack by various soil borne diseases. However, the research work world over shows that sweet pepper can be grown successfully in soilless growing media but the initial investment is proving to be bottleneck in its adoption. Hence, there is an urgent need to identify cost effective soilless growing media to grow capsicum under protected conditions. Keeping this in view, the present investigation entitled “Standardisation of growing media for production of coloured capsicum under polyhouse” was conducted during 2016 and 17 at the Experimental Research Farm of Precision Farming Development Center, Department of Soil Science and Water Management of Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan. Seeds of variety Orobelle (coloured capsicum) were planted February in plug trays then transplanted in UV stabilized polybags during March, in both the years (2016-17) under polyhouse conditions. A total of 9 treatments were replicated thrice for each growing media which were as follows : T1 Cocopeat , T2 Cocopeat + Vermicompost (70:30) + Jeevamrut (5% foliar spray), T3 Cocopeat + Jeevamrut (5% foliar spray), T4 Vermiculite, T5 Vermiculite + Vermicompost (70:30) + Jeevamrut (5% foliar spray), T6 Vermiculite + Jeevamrut (5% foliar spray), T7 Sand, T8 Sand + Vermicompost (70:30) + Jeevamrut (5% foliar spray), T9 Sand + Jeevamrut (5% foliar spray) under CRD (Completely Randomised Block Design) layout design. The experimental results showed that among different combinations of growing media, maximum (119.50 cm) plant height, minimum (40.50 days) days to 50% flowering, minimum (69.17) days to marketable maturity, maximum (25.67) number of fruits per plant, maximum (207.43 g), average fruit weight, maximum (5.32 kg) fruit yield per plant, maximum (99.67 days) harvest duration were recorded in T8 (Sand + Vermicompost (70:30) + Jeevamrut (5% foliar spray)). Maximum macro and micro nutrients were also recorded under the same treatment. Highest (2.59:1) benefit cost ratio was recorded in treatment T8 (Sand + Vermicompost (70:30) + Jeevamrut (5% foliar spray)) which can be judged as the most profitable and cost effective, growing media for coloured capsicum under polyhouse condition.
