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 SOWING DATES AND INTEGRATED PEST MANAGEMENT MODULES ON SEED YIELD AND QUALITY OF OKRA (Abelmoschus esculentus (L.) Moench)
    (UHF,NAUNI, 2017-10) BRICE, ANJALI; VERMA, SUBHASH CHANDER
    ABSTRACT The present investigations entitled “Effect of sowing dates and integrated pest management modules on seed yield and quality of okra (Abelmoschus esculentus L. Moench)” were conducted during the year 2016 at the Pandah Research Farm of Department of Seed Science and Technology, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out in Randomized Complete Block Design (Factorial) with three replications. The okra cv. P-8 was sown at three different sowing dates viz., 1st June, 15th June and 30th June, 2016 under six integrated pest management modules and untreated control. The experimental results showed that among the three sowing dates the crop sown at sowing-I (seed yield: 25.67 q/ha) performed better than the crop sown at sowing-II (22.61 q/ha) and sowing-III (20.82 q/ha). IPM module-I (Seed treatment with imidacloprid @ 3 ml/kg, foliar spray of imidacloprid @ 0.3 ml/litre at 40 DAS, foliar spray of spinosad @ 0.3 ml/litre at 50 DAS, emamectin benzoate @ 0.4 g/litre at 70 days, foliar spray of spinosad @ 0.3 ml/litre at 80 DAS) was superior than rest of the modules for the traits studied viz., growth parameters i.e. plant height (49.35 cm at 45 DAS and 153.02 cm at harvest), number of branches per plant (7.76 at 45 DAS), number of leaves per plant (19.76 at 45 DAS), days to 50 % flowering (42 days), number of fruits per plant (16.22), fruit length (16.66 cm) and fruit breadth(18.67 mm), seed quality parameters i.e. number of seeds per fruit (54.64), hundred seed weight (5.63 g), seed yield (28.78 q/ha), seed germination (95.11 %), seed vigour index-I (1998.63), seed vigour index-II (2773.14) and electrical conductivity (455.33 μS/cm) and provided maximum protection against insect pests (4.13 jassids/plant and 0.24 blister beetles/plant). The next best IPM module was module-IV which resulted 27.65 q/ha seed yield followed by module-III (24.59 q/ha), module-II (24.10 q/ha), module-VI (20.70 q/ha) and module-V (20.16 q/ha).The study revealed that among the different combinations of sowing dates and IPM modules the maximum plant height at 45 days after sowing ( 56.63 cm), plant height at harvest (155.77 cm), number of branches per plant (8.80) at 45 days after sowing, number of leaves per plant (24.53) at 45 days after sowing, number of fruits per plant (17.73), fruit length (17.57 cm), fruit breadth (19.15 mm), number of seeds per fruit (58.53), seed yield (47.84 g/plant, 2.39 kg/plot and 31.89 q/ha), hundred seed weight (5.71 g), seed germination (97 %), seedling length (23.17 cm), seedling dry weight (30.11 mg), seed vigour index-I (2247.20), seed vigour index-II (2920.64) and minimum electrical conductivity (444.33 μS/cm), population of jassid (3.40 jassids/plant) and blister beetle (0.09 blister beetles/plant) was recorded at sowing-I (1st June) with module-I. Hence, the crop sown at sowing-I with IPM module-I was most suitable for plant growth and provided maximum protection from insect pests which resulted higher yield of quality seeds in okra.
