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.

ThesisItem Open Access STUDIES ON THE EFFECT OF SEED PELLETING AND INTEGRATED NUTRIENT MANAGEMENT IN BELL PEPPER (Capsicum annuum L.)(UHF, NAUNI, 2018-12) VERMA, ROHIT; MEHTA, D KABSTRACT The present investigation entitled “Studies on the Effect of Seed Pelleting and Integrated Nutrient Management in Bell Pepper (Capsicum annuum L.) was carried out in the laboratory and khaltoo experimental farm of Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan HP during Kharif season for two consective years (2016-17 and 2017-18). The present research programme was carried out in two phases. In first experiment the seeds of bell pepper cv. Solan Bharpur were pelleted with NPK (19: 19: 19), Multiplex, Potassium dihydro orthophosphate (KH2PO4), Zinc sulphate (ZnSO4), Boric acid (H3BO3), Magnesium sulphate (MgSO4), Copper sulphate (CuSO4), NPK (19: 19: 19) + Multiplex, NPK (19: 19: 19) + KH2PO4 , NPK (19: 19: 19) + ZnSO4 , NPK (19: 19: 19) + (H3BO3), NPK (19: 19: 19) MgSO4, NPK (19: 19: 19) + CuSO4, Wood ash, Control (unpelleted seed). NPK and multiplex were used @ 5 gm/kg seed, all other micronutrients were used @ 300 mg/ kg of seed and wood ash was used @ 3000 g/kg of seed and tested for seed germination and vigour under laboratory and nursery conditions. It was found that seed pelleted with zinc sulphate produced best results for characters like germination, seedling length, seedling dry weight, seedling vigour index-L and seedling vigour index-M under laboratory and nursery conditions, whereas maximum speed of germination was recorded in unpelleted seeds under nursery conditions. Three best pelleting treatments i.e. Zinc sulphate, dihydro orthophosphate and Boric acid were shortlisted from experiment1 for further field studies. The second experiment was carried out under open field conditions in two sets seperately, set-1 for fresh market fruit crop and set-2 for seed crop. Three best pelleting treatments (as recorded in experiment-1) alongwith unpelleted control combined with six INM treatments i.e. recommended dose of NPK (100:75:75 kg/ha), Azotobacter (2.5 kg/ha) + PSB (2.5 kg/ha) + KSB (2.5 kg/ha), Azotobacter + PSB + KSB + 90% recommended dose of NPK, Azotobacter + PSB + KSB + 80 % recommended dose of NPK, Azotobacter + PSB + KSB + 70% recommended dose of NPK and Azotobacter + PSB + KSB + 60 % recommended dose of NPK. Biofertilizers were applied as seedling dip at transplanting and soil application. In the set- I (fresh market crop), seeds pelleted with zinc sulphate + application of Azotobacter + PSB + KSB + 80 % recommended dose of NPK produced maximum values for characters like plant height, harvesting duration, fruit weight, fruit length, fruit width, number of fruits/plant, fruit yield/plant, fruit yield/plot, fruit yield/ha, whereas, same treatment produced minimum values for days to 50 % flowering and days to fruit harvesting. In the set- II (seed crop), again the seed pelleted with zinc sulphate + application of Azotobacter + PSB + KSB + 80 % recommended dose of NPK produced maximum values for characters like ripe fruit weight, ripe fruit length, ripe fruit width, number of ripe fruits/plant, ripe fruit yield/plant, number of seed/fruit, seed yield /plant, seed yield/plot, seed yield/ha, 1000 seed weight, germination, seedling length, seedling dry weight, seed vigour index-Length, seed vigour index-Mass, whereas, same treatment produced minimum days to fruit harvesting. Seeds pelleted with potassium dihydro orthophosphate + application of Azotobacter (2.5 kg/ha) + PSB (2.5 kg/ha) + KSB (2.5 kg/ha) + 80 % recommended dose of NPK (P3N4) produced minimum ripe fruit rot incidence. Therefore, seed pelleting with zinc sulphate @ 300 mg/kg seed + application of Azotobacter + PSB + KSB as seedling dip at transplanting and soil application + 80 % recommended dose of NPK can be recommended for getting higher yield of fresh fruits as well as seed crop of bell pepper in Himachal Pradesh.ThesisItem Open Access STUDIES ON SEED PRIMING IN SWEET PEA (Lathyrus odoratus L.)(UHF, NAUNI, 2018-10) CHOUHAN, RAJNISH; DILTA, B SABSTRACT The present investigation titled, “Studies on seed priming in sweet pea (Lathyrus odoratus L.)” was carried out at the Experimental Farm of Department of Seed Science & Technology, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H P) during 2017-18.

Among different priming treatments, T5 i.e. Priming of seeds with GA3 @ 100 ppm for 24 hours recorded maximum values for 100 seed weight (8.09 g), speed of germination (26.25), germination percentage (87.75 %), seedling length (30.25 cm), seedling dry weight (19.27 mg), seed vigour index-I (2654.25) and seed vigour index-II (1691.21). The experiment-II was conducted in a Randomized Block Design and replicated thrice under field conditions. To accomplish this experiment, the seeds were taken treatment wise as mentioned in the experiment-I. the results obtained indicated that T5 i.e. priming of seeds with GA3 @ 100 ppm for 24 hours observed maximum values for field emergence (80.25 %), plant height 30 DAS (29 cm), plant height 60 DAS (56.71 cm), plant height at final harvest (134.17 cm), number of flowers / plant (33.78), number of flowers / plot (912.15), size of flower (3.06 cm), duration of flowering (48.50 days), numbers of pods / plant (26.83), number of seeds / pod (7.43), number of seeds/plant (199.35), seed yield / plant (13.51 g) and seed yield / plot (336.77 g) as well as minimum days taken to first flowering (106.00 days),. The experiment-III was laid out in a Completely Randomized Design with four replications under laboratory conditions. The seeds were taken treatment wise harvested from the plants grown under experiment-II. The results revealed that the seeds harvested from the plants raised from the seeds following priming with GA3 @ 100 ppm for 24 hours recorded maximum values for 100 seed weight (6.78 g), speed of germination (24.67), germination percentage (85.25 %), seedling length (25.82 cm), seedling dry weight (14.71 mg), seed vigour index-I (2201.19) and seed vigour index-II (1253.85). Hence, it is concluded that for better plant growth, flowering, maximum seed yield as well as production of quality seeds, the sweet pea seeds be primed with GA3 @ 100 ppm for 24 hours.ThesisItem Open Access EFFECT OF DIFFERENT CLOVE WEIGHT AND SOIL AMENDMENTS ON THE YIELD AND QUALITY OF GARLIC BULBS(UHF, NAUNI, 2018-10) GARHWAL, SHIPRA; KUMAR, MANISHABSTRACT The present investigation entitled “Effect of different clove weight and soil amendments on the yield and quality of garlic bulbs” was conducted during Rabi season of 2017-18 at Khaltoo farm of department of Seed Science and Technology, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan. The experiment was laid out in Randomized Block Design (factorial) with three replications of each treatment combination (clove weight x soil amendments). The observations were recorded on plant height, number of leaves per plant, bulb yield (kg/plot) and q/ha), diameter of bulb, weight of clove, TSS etc. Analysis of variance showed significant differences among all the treatment combinations for all the characters under study. Highest bulb yield per plot (1.90 kg) was obtained with the treatment combination S3T2 (clove weight of >5g and vermicompost @5 kg). Moreover clove weight S3 (>5g) and soil amendment T2 (vermicompost @5 kg) independently as well as in their combination also gave the best results for most of the growth and yield characters. Therefore, clove weight S3 (>5g) in combination with soil amendment T2 (vermicompost @5 kg) can be recommended for commercial cultivation for getting the higher yields in garlic.ThesisItem Open Access EFFECT OF CUTTINGS AND DIFFERENT FERTILIZER DOSES ON GREEN LEAF AND SEED YIELD IN FENUGREEK (Trigonella foenum-graecum L.)(UHF, NAUNI, 2018-10) DEVI, POOJA; KUMAR, MANISHABSTRACT The present investigation entitled “Effect of cuttings and different fertilizer doses on green leaf and seed yield in fenugreek (Trigonella foenum-graecum L.)” was carried out in cv.

Firstly, in vitro screening of three indigenous isolates each of plant growth promoting rhizobacteria (PGPR 1, PGPR 2 & PGPR 3) and biocontrol agents (Trichoderma viride, T. harzianum & T. hamatum) as seed treatment was done. Based on germination percentage, speed of germination, seedling vigour index – length (SVI-L) and seedling vigour index – mass (SVI-M), PGPR 3 and T. harzianum were selected from PGPRs and BCAs, respectively for further evaluation. Nine treatment combinations based on seed treatment (108cfu/ml of PGPR & 106cfu/g of Trichoderma) and soil application (talc formulation mixed with FYM @ 2%) of these two bio-agents were used viz., PGPR3 seed treatment (T1), T. harzianum seed treatment (T2), PGPR3 soil application (T3), Trichoderma soil application (T4), PGPR seed treatment + T. harzianum soil application (T5), PGPR3 soil application + T. harzianum seed treatment (T6), PGPR3 seed treatment + PGPR3 soil application (T7), T. harzianum seed treatment + T. harzianum soil application (T8) and Untreated control (T9). Under nursery conditions, maximum germination (86.20 %), maximum speed of germination (87.50), maximum seedling length (11.97cm), maximum seedling dry weight (4.45 mg), maximum seedling vigour index – length (SVI-L) (1011.16), maximum seedling vigour index – mass (SVI-M) (384.42), were recorded with PGPR seed treatment + T. harzianum soil application (T5) and minimum was recorded with untreated control. Under field conditions (fresh crop), maximum plant height (70.42 cm), number of fruits/plant (9.50), average fruit weight (44.01 g), fruit size (42.05 cm), harvest duration (56.67 days), number pickings (7.93), fresh fruit yield/ plant (922.33 g), fruit yield/plot (13.83 kg) and fruit yield/ha (403.17 q) were recorded with PGPR3 seed treatment + T. harzianum soil application (T5) and minimum was recorded in untreated control. In field experiment (seed crop), highestnumber of ripe fruits/plant (7.75), fruit weight (48.46 g), fruit size (44.37 cm), fruit yield/plot (15.58 kg), fruit yield/ha (450.37 q), number seeds/fruit (177.51), seed yield/plot (236.63 g), seed yield/ha (673.50 kg), 1000 seed weight (6.63 g), seed recovery (1.58%), quality of harvested seed were recorded with PGPR seed treatment + T. harzianum soil application (T5) and minimum was recorded in untreated control.This treatment combination also showed minimum incidence of major diseases viz. Cercospora leaf spot (5.10%), anthracnose (1.70%) and Phytophthora fruit rot (10.78 %) as compared to other treatments and control. It can be concluded from the present investigation that seed treatment with PGPR3 (108cfu/ml) for 4 hrs before sowing in nursery and soil application of talc formulation of Trichoderma harzianum (106cfu/gm) mixed with FYM @ 2% w/w in nursery and field enhanced plant growth, fresh fruit yield, seed yield and quality of harvested seed in bell pepper cv. Solan Bharpur. The treatment combination also reduced incidence of major diseases like anthracnose, Phytophthora fruit rot and Cercospora leaf spot under field conditions.
