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 SEED PRODUCTION TECHNOLOGY OF ONION (Allium cepa L.) UNDER CHANGING CLIMATIC CONDITIONS IN MID HILLS OF HIMACHAL PRADESH
    (UHF,NAUNI, 2018-04) MANOHAR, LAL; KANWAR, H.S.
    ABSTRACT The present investigation entitled “Studies on seed production technology of onion (Allium cepa L.) under changing climatic conditions in mid hills of Himachal Pradesh” was carried out during Rabi season of 2014-15 and 2015-16 in the Experimental Research Farm and Laboratory of the Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh using cv. ‘Palam Lohit’ under four experiments. The first experiment on ‘Effect of mulching and date of bulb transplanting on seed production of onion’ comprised of twenty treatment combination of mulching (black polythene mulch, silver-black polythene mulch, crop residues and no mulch) and dates of bulb transplanting (1st September, 15th September, 30th September, 15th October and 30th October) with spacing 45 × 45 cm. Second experiment on ‘Effect of mulching and planting geometry on seed production of onion’ comprised of sixteen treatment combinations of mulching (black polythene mulch, silver-black polythene mulch, crop residues and no mulch) and planting geometries [(45+45) × 45 cm, (60+30) × 45 cm, (45+45) × 30 cm and (60+30) × 30 cm]. Third experiment on ‘Effect of mulching and date of seedling transplanting in seedto- seed method of onion seed production’ which comprised of twenty treatment combination of mulching (black polythene mulch, silver-black polythene mulch, crop residues and no mulch) and dates of seedling transplanting (1st August, 15th August, 1st September, 15th September and 30th September) with spacing 45 × 45 cm. The experiments were laid in a Split Plot Design in field and Completely Randomized Design (Factorial) in laboratory which were replicated thrice. The observations were recorded on growth characters viz. plant height (cm), days to 50 per cent flowering, number of umbels per plant, number of umblets/umbel, umbel diameter (mm) and length of flowering stalk (cm); seed yield characters viz. number of seeds per umbel, number of seeds per plant, seed yield per plant (g), seed yield/plot (g) and seed yield/ha (kg); and seed quality attributed viz. 1000 seed weight (g), electrical conductivity of seeds (μSm-1), seed germination (%), speed of germination, seedling length (cm), seedling fresh weight (mg), seedling dry weight (mg), seedling vigour index-I and II. In the fourth experiment entitled ‘Impact of climate change on seed yield of onion’, data on various weather parameters (1985-2014) and onion seed productivity (1988-89 to 2013-14) was collected for linear regression and correlations analysis to study the trends of various weather parameters as well as their relationship with productivity. First experiment revealed that the treatment combination 15th October and black polythene mulch exhibited maximum values for almost all the growth characters, seed yield and seed quality attributes. The treatments have non-significant effect on electrical conductivity. Treatment combination 30th October and black polythene mulch was at par with best treatment combination for seed yield (per plant, per plot and per hectare). Second experiment revealed that treatment combination black polythene mulch and (45+45)×45 cm planting geometry was found superior for all the growth characters, seed yield attributes like number of seeds per umbel, number of seeds per plant and seed yield per plant; and seed quality attributes. On the other hand, onion bulbs planted in (45+45)×30 cm planting geometry on black polythene mulch resulted in higher seed yields (per plant, per plot and per hectare). Third experiment revealed that onion seedling transplanted on 1st September on black polythene mulch performed best for almost all the growth characters, seed yield attributes and seed quality characters. Lastly, the fourth experiment revealed that annual temperature showed an increasing trend in study area; whereas, the annual total rainfall as well as relative humidity showed a decreasing trend. The onion seed productivity over 26 years (1988-89 to 2013-14) showed a fluctuating pattern with an overall decreasing trend. Finally, in bulb to seed method 15th October date of bulb transplanting with (45+45)×30 cm planting geometry on the black polythene mulch; and in seed-to-seed method 1st September date of seedling transplanting on black polythene mulch may be recommended for commercial seed production of onion cv. ‘Palam Lohit’ after verification of results in the farmers field to neutralize the adverse effect of the climate change.

    STUDIES ON PLANTING DENSITY AND TRAINING ON SEED PRODUCTION OF BELL PEPPER (Capsicum annuum L.) UNDER PROTECTED CONDITIONS
    (2013) MANOHAR, LAL; KANWAR, H.S.
    ABSTRACT The present investigations entitled “Studies on planting density and training on seed production of bell pepper (Capsicum annuum L.) under protected conditions were carried out using cv. Solan Bharpur. The experiment was laid out in Randomized Block Design (Factorial) in the field and in Completely Randomized Block Design (Factorial) in Laboratory with four replications of each treatment combination in both the experiments at Seed Technology and Production Center, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif 2012. The treatment combinations comprised of three planting densities (S) viz., S1 (45x15 cm), S2 (45x30 cm) and S3 (45x45 cm) and four training levels (T) viz., T1 (single shoot), T2 (two shoots), T3 (three shoots) and T4 (four shoots). The observations were recorded in the field on plant height (cm), days to ripe fruit harvest, powdery mildew severity, ripe fruit weight (g), ripe fruit length (cm), ripe fruit width (cm), number of ripe fruits/plant, ripe fruit yield per plant (Kg), number of seeds/fruit, per cent seed recovery, seed yield/plant (g), seed yield/m2 (g), seed yield/ha (Kg), 1000 seed weight and benefit: cost ratio. While the observations recorded in the laboratory were germination (%), seedling length (cm), seedling dry weight (mg), seedling vigor index-I & II. Analysis of variance showed significant differences among the treatment combinations for all the characters studied except percent seed recovery. The combination S2T2 (plants spaced at 45x30 cm and trained to two shoots) was found superior over all other treatments in terms of economic characters such as total fruit yield/plant, seed yield (per plant, per m2 and per hectare) and benefit: cost ratio. The treatment combination S3T1 (plant spaced at 45x45 cm and trained to single shoot) performed best for many fruit and seed characters but it gave lower seed yield and was uneconomic. Therefore, planting density 45x30 cm in combination with two shoot training system i.e. S2T2 can be recommended for commercial seed production of bell pepper.
