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 STAGGERED PLANTING AND JEEVAMRIT APPLICATION ON FLOWER AND CORM PRODUCTION OF GLADIOLUS (Gladiolus hybrida L.)
    (UHF Nauni, 2024-05-06) NEHA GRACE ANGEL KISKU; Puja Sharma
    The present investigation entitled “Studies on staggered planting and jeevamrit application on flower and corm production of Gladiolus (Gladiolus hybrida L.)” was carried out at Research Farm of Department of Floriculture and Landscape Architecture, Dr. YS Parmar University of Horticulture and Forestry, (Nauni) Solan (HP) for two consecutive years; 2022 and 2023. The experiment was laid out in RBD (Factorial) with three replications. Two cultivars ‘Punjab Dawn’ and ‘Pusa Kiran’ were planted at three different dates (25th January, 25th February and 25th March) and were given two drench applications of jeevamrit @ 20% (15 days interval, 30 days interval) along with RDF as control. Between the cultivars, ‘Punjab Dawn’ when planted on 25th January and drenched with jeevamrit at 15 days interval, resulted in maximum number of florets (13.73) and floret size (10.00 cm). Staggered planting of gladiolus on 25th January, 25th February and 25th March resulted in continuous flowering from early May to late July. The 25th January planting is the most profitable with a benefit-cost ratio of 3.73 and is best for corm production, yielding the highest number and quality of corms and cormels. Applying jeevamrit as a drench at 15 days interval produces high-quality gladiolus stems, enhancing spike length, number of florets, and vase life. This method yields the highest benefit-cost ratios: 3.73 for 'Punjab Dawn' and 3.33 for 'Pusa Kiran'. For corm production, jeevamrit drenching every 15 days also results in the best outcomes in terms of the number of corms per plant, corm weight, and corm size.

    OFF-SEASON POT MUM (Dendranthema grandiflora TZVELEV) PRODUCTION THROUGH PHOTOPERIODIC MANIPULATION AND PINCHING
    (UHF Nauni, 2024-05-28) DIVESH THAKUR; Puja Sharma
    The present investigation entitled “Off-season pot mum (Dendranthema grandiflora Tzvelev) production through photoperiodic manipulation and pinching” was carried out at Research Farm of Department of Floriculture and Landscape Architecture, Dr. YS Parmar University of Horticulture and Forestry, (Nauni) Solan (HP) for two consecutive years; 2022 and 2023. The experiment was laid out in CRD (Factorial) with three replications. For pot mum production, genotype ‘UHFSChr-56’ was planted at six different times of the year (15th March, 15th April, 15th May, 15th June, 15th July and 15th August) with four pinching treatments (no pinch, single pinch, double pinch and triple pinch) under two photoperiodic conditions (natural photoperiod and controlled photoperiod). In March planting, triple pinching resulted in the production of best quality pots with maximum pot presentability (95.88 and 94.95 during 2022 and 2023, respectively) and benefit-cost ratio (5.34 in controlled photoperiod). In April planting, the best pots were noted in triple pinch with maximum pot presentability (97.57 and 96.50 during 2022 and 2023, respectively) and benefit-cost ratio (5.44 in controlled photoperiod). In case of May planting, the best results of pot presentability (97.56 and 96.68 during 2022 and 2023, respectively) and benefit-cost ratio (4.83 in natural photoperiod) were observed in triple pinch. Further, June planting resulted in maximum pot presentability (97.16 and 96.08 during 2022 and 2023, respectively) and benefit-cost ratio (5.16 in natural photoperiod) when plants were subjected to triple pinch. However, in July planting, double pinched plants gave the best results for pot presentability (95.65 and 94.62 during 2022 and 2023, respectively) and benefit-cost ratio (4.84 in natural photoperiod). In August planting, single pinched plants gave the best result of pot presentability (87.16 and 86.67 during 2022 and 2023, respectively) and benefit-cost ratio (4.59 in natural photoperiod). Further, out of all planting dates, April planting of ‘UHFSChr-56’ subjected to triple pinch and grown under controlled photoperiod produced the best quality offseason pots with maximum benefit-cost ratio (5.44). Hence, off-season flowering pots of ‘UHFSChr-56’ could be successfully produced by staggered planting starting from March to August using different pinching treatments.

    The present investigation entitled “Studies on integrated nutrient management in Marigold (Tagetes erecta L.) cv. ‘Siracole’” was carried out at the experimental farm of the Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the years 2021-22 and 2022-23. In the experiment different combinations of organic fertilizers i.e. Jeevamrit, Humic acid and Seaweed extract with different levels of inorganic fertilizer dose (30:20:20 g/m2 NPK) i.e. 100%, 80% and 60% were used. Thirteen such treatment combinations were made and the experiment was laid out in Randomized Block Design (RBD) with three number of replications. Results from the experiment showed that vegetative and flowering parameters viz., plant spread (55.49 cm), number of primary branches (8.54), number of secondary branches (63.19), duration of flowering (97.70 days), size of flower (7.06 cm), number of marketable flowers per plant and per square meter (181.93 and 1631.00, respectively), weight of single flower (8.88 g), flower yield per plant (1526.56 g) and flower yield per square meter (11.42 kg) was found maximum when plants were treated with the foliar application of 5% Jeevamrit (at 15 days interval) and 80% Inorganic fertilizer dose (30:20:20 g/m2 NPK). Additionally regarding the plant physico-chemical properties, fertilizer treatment i.e. foliar application of 5% Jeevamrit (at 15 days interval) and 80% Inorganic fertilizer dose (30:20:20 g/m2 NPK) also showed high nitrogen, phosphorus and potassium (4.65%, 2.16% and 7.20%, respectively) and total chlorophyll content (41.73 mg/100g) in the leaves of marigold plant. Moreover, for soil physico-chemical analysis high nitrogen (403.47 kg/ha), phosphorus (41.88 kg/ha), potassium (342.45 kg/ha), organic carbon (1.50%) and viable microbial count (110.67 x 105 cfu/g) in the soil were found under the treatment comprising of drench application of 5% Jeevamrit (at 15 days interval) along with 80% Inorganic fertilizer dose (30:20:20 g/m2 NPK). Further, foliar application of 2% Humic acid (at 15 days interval) in combination with 80% Inorganic fertilizer dose (30:20:20 g/m2 NPK) was found to be superior in terms of carotenoids content (163.33 mg/100g), total flavonoids (232.13 mg/100g), total polyphenols (313.07 mg/100g) and antioxidant activity (87.87%) in flower petals. Earliness in flowering (81.61 days) and maximum shelf life of flowers (5.91 days) was also observed under this treatment. While working out the benefit cost ratio, maximum B:C ratio (4.01:1) was calculated under the treatment comprising of foliar application of 5% Jeevamrit (at 15 days interval) with 80% Inorganic fertilizer dose (30:20:20 g/m2 NPK).

    (UHF Nauni, 2024-05-18) NITESH KAUSHAL; Bharati Kashyap
    The present investigation titled “Studies on the influence of nutritional and growth regulator modules on quality cutting production of Marigold (Tagetes erecta L.) cv. Siracole” was carried out at the Research Farm of Department of Floriculture and Landscape Architecture, Dr. YS Parmar University of Horticulture and Forestry, (Nauni) Solan (HP) for three consecutive years; 2022, 2023 and 2024. The experiment was laid out in RBD (Factorial) with three replications. The two experiments were conducted on the effect of different nutritional modules and growth regulators on cutting production of marigold cv. ‘Siracole’ and the comparative effect of cutting production modules on growth and flowering. In Experiment-I, it was observed that the application of 30-20-20 g/m2 NPK with exogenous application of GA3 @ 100 ppm resulted in longer cutting length (10.58 cm) whereas number of cuttings per plant (92.92) and per m2 (826.64) was observed more when mother block was treated with BA @ 100 ppm + RDF. Jeevamrit application @ 2 L/m2 at 15 days interval produced the cuttings with maximum diameter (3.64 mm), weight of cuttings (1.62 g), rooting percentage (84.50 %), maximum number of roots per cutting (35.46) and survival percentage (81.59 %). Out of the harvesting flushes, the cuttings produced from second flush (H2) were having maximum diameter of cuttings (3.57 mm) and weight of cuttings (1.73 g) which was at par with H1, while the maximum rooting percentage (81.90 %), maximum number of roots per cutting (29.78) and maximum survival percentage (78.07 %) was observed in H1. Out of the seasons, more rooting percentage (82.43 %), maximum number of roots per cutting (30.11) and survival percentage (80.53 %) was observed in summer season. In Experiment-II, Out of three flushes (H1) i.e. first harvest of cuttings was better in terms of number of marketable flowers per square meter (1054.21), marketable flower yield per plant (844.69 g) and marketable flower yield per square meter (97.27 kg). Out of seasons, the cuttings planted during summers resulted into maximum number of marketable flowers per square meter (1047.93), marketable flower yield per plant (938.39 g) and marketable flower yield per square meter (8.00 kg). Both the nutritional modules i.e. Jeevamrit @ 2 L/m2 and RDF produced equivalent number of marketable flowers per square meter (1021.59 and 1012.81; respectively), marketable flower yield per plant (853.85 and 821.62 g; respectively) and marketable flower yield per square meter (7.29 and 7.00 kg; respectively). Hence, it can be concluded that Jeevamrit @ 2 L/m2, an organic amendment, can serve as an alternative to chemical fertilizers for quality flower production in marigold cultivar ‘Siracole’

    STUDIES ON CUTTING PRODUCTION OF NOVEL MUTANTS OF CARNATION (Dianthus caryophyllus L.) UNDER THE ORGANIC AND INORGANIC FERTILIZATION SYSTEM
    (UHF Nauni, 2024-05-24) SHREEDHAR BEESE; SR Dhiman
    The present investigation entitled, “Studies on cutting production of novel mutants of carnation (Dianthus caryophyllus L.) under the organic and inorganic fertilization system’’ was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during the years 2022 and 2023. The study included two experiments which were conducted separately on cutting production of novel mutants of carnation under the influence of different fertilization modules and storage of unrooted cuttings and their subsequent rooting behavior after storage to regulate the market demands. In the first experiment to determine the best fertilizer module for obtaining quality cuttings in six different carnation genotypes i.e., ‘UHFSCar-1’, ‘UHFSCar-4’, ‘UHFSCar-5’, ‘UHFSCar-11’, ‘UHFSCar-18’, ‘UHFSCar-22’. The experiment was laid out in Randomized Block Design (Factorial) with 3 fertilizer modules and 6 genotypes, replicated thrice. The second experiment was conducted with the main objective was to find out the effect of pre-harvest organic and inorganic fertilization modules on cold storage and rooting of carnation cuttings of six different genotypes which are fertilized with different fertilizer modules. The experiment was laid out in Completely Randomized Design (Factorial) with 3 storage durations along with the control, 3 fertilizer modules and 6 genotypes, replicated thrice. Findings of the first experiment revealed that fertilizer module FM3 comprising of RDF-20-5-5 g/m² NPK (as basal) + 200ppm N [80 ppm Nano Urea + 80 ppm Potassium nitrate (multi K) +40 ppm Ca(NO3 )2 ]+ 280 ppm K (as fertigation twice a week, starting after 30 days of planting) resulted in the production of cuttings with minimum days taken for first and successive harvesting of cuttings (23.07 days), maximum diameter (0.85 cm), weight (7.89 g), Internodal length (1.67 cm), number of leaves (8.80), number of cuttings per plant per harvest (6.26), total number of cuttings (22.10), yield of cuttings per meter square (152.78) and cost benefit ratio (1:7.43). Results of the second experiment revealed that cuttings stored for 15 days resulted in minimum percentage of weight loss (6.15 %) and maximum cost benefit ratio (1:1.98). Cuttings that were stored for 15 days (S1) and 30 days (S2) resulted in 93-97 per cent rooting. The studies also indicated that carnation cuttings can be stored up to 45 days at 4°C without significant change in quality and quantity of cuttings.

    (UHF Nauni, 2024-04-09) SABHYA PATHANIA; Sita Ram Dhiman
    The present investigation entitled, “Effect of organic and inorganic fertilization on growth and flowering of chrysanthemum in response to staggered planting” was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during 2021-22 & 2022-23 under open field conditions. The experiment comprised of 24 treatment combinations of two cultivars (‘Purnima’ and ‘Solan Shringar’), six planting dates (15 June, 30 June, 15 July, 30 July, 15 August and 30 August), two fertilization modules i.e. inorganic (RDF) and organic (Jeevamrit @ 30 ml/plant as drenching at 15 days interval). Findings revealed that June 15 planted crop of ‘Solan Shringar’ under the influence of inorganic fertilization recorded maximum plant height (76.18 cm and 86.64 cm, respectively), plant spread (33.52 cm and 38.04 cm, respectively), number of cut stems per plant (5.13 and 5.53, respectively), length of cut stem (65.68 cm and 75.03 cm, respectively), stem strength (9.70o and 9.17o, respectively), duration of flowering (23.00 days and 26.33 days, respectively) and b.c ratio (1.82 and 1.93, respectively) during both the years. Whereas, June 15 planted crop of ‘Purnima’ under inorganic fertilization module recorded maximum flower diameter (11.46 cm and 12.14 cm, respectively), available nitrogen in soil (325.84 kg/ha and 327.21 kg/ha, respectively), available phosphorous in soil (39.37 kg/ha and 41.35 kg/ha, respectively) and available potassium in soil (358.90 kg/ha and 360.05 kg/ha, respectively) during both the years. June 15 planted crop of ‘Purnima’ under organic fertilization module proved better for vase life (17.73 days and 18.53 days, respectively), organic carbon content in soil (1.154% and 1.171 %, respectively) during both the years, however, viable microbial count viz., bacterial, actinomycetes and fungal (133.68 × 107 cfu g-1 soil, 62.91 × 102 cfu g-1 soil and 31.88 × 102 cfu g-1 soil, respectively), viable microbial biomass (53.69 μg g-1 soil) and enzymes viz., Dehrogenase and Phosphatase (4.18 mg TPF h-1 g-1 soil and 26.45 μmole PNP h-1 g-1 soil, respectively) in soil were recorded after the termination of field experiment. Minimum number of days taken to visible bud initiation (34.87 days and 28.87 days, respectively) and days taken to reach the harvesting stage (93.60 days and 76.53 days, respectively) were recorded in ‘Purnima’ when planted on August 30 under the inorganic fertilization module during both the years. This suggests that organic fertilization module can act as an alternative for chemical fertilizers in consideration to the low input cost along with improving soil health and have the potential to contribute to better financial outcomes.

    (UHF Nauni, 2024-03-04) ALI HAIDAR SHAH; Priyanka Thakur
    “Effect of covering materials on off season flower production of chrysanthemum (Dendranthema x grandiflora Tzevelev.) cultivars under low hills of HP” were carried out at the experimental farm of the RHR&TS Dhaulakuan, Sirmour under Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, during 2022 and 2023 under naturally ventilated poly tunnels. The experiment was carried out using three types of covering materials (viz. tarpaulin, HDPE* and black satin cloth) and four cultivars each of standard and spray varieties. Findings revealed that HDPE* was the best alternative covering material to tarpaulin as optimum plant height (56.47 cm), plant spread (37.34 cm), maximum number of cut stems (3.14), and earliest coloured flower bud was recorded. Flowering was earlier under HDPE photoperiod than black satin cloth. Flower harvest was earliest (122.72 days) in plants under HDPE* cover as compared to plants under Black satin cloth conditions which took maximum number of days (131.63 days) to reach flowering. The varieties were categorized to different response group under controlled photoperiodic conditions with HDPE*. Out of eight varieties, only six varieties (‘Yellow Star’, ‘White Star’, ‘Purnima’ and ‘Surf’, ‘Apricot Parasol’, ‘Well Spring White’) were found suitable for off- season flower production for low hills of HP. *HDPE-High Density Polyethylene

    EVALUATION OF DIFFERENT GENOTYPES OF CARNATION (Dianthus caryophyllus L.) IN RESPONSE TO ORGANIC AND INORGANIC FERTILIZATION MODULES
    (UHF,NAUNI, 2023-11-29) RACHEL VANLALHRUAII; S R DHIMAN
    ABSTRACT The present investigation entitled, “Evaluation of different genotypes of carnation (Dianthus caryophyllus L.) in response to organic and inorganic fertilization modules” was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during 2020-2022 under polyhouse with the objectives to find out the possibility of organic cultivation of carnation and to identify suitable genotype(s) for organic and inorganic cultivation. The experiment comprised of fourteen genotypes of carnation and two treatments: inorganic fertilization module (Recommended Dose of Fertilizers) and organic fertilization module (Jeevamrit @ 20 ml/plant as drenching at 30 days interval). The experiment was laid out in Randomized Block Design (Factorial) with three replications. The results revealed that carnations performed well in both the fertilization modules, the organic fertilization module however performed better in multiple characteristics, including stem thickness (5.75 cm), lesser number of days taken for bud formation (149.14 days), bud width (19.61 mm), number of flowers per plant and per square metre (5.55 cut flowers per plant and 133.20 cut flowers per m2), lesser number of days taken for harvesting of cut stem (179.43 days), longer duration of flowering (72.20 days) and profitability. Even though, quality parameters such as stem length and stem sturdiness were non-significant, yield showed significant results. The organic fertilization module increased the bacterial count at 107 dilution from the initial value of 97.67 cfu g-1 to 122.33 cfu g-1. The actinomycetes count at 102 dilution also increased from the initial value of 37.67 cfu g-1 to 57.67 cfu g-1. The initial fungal count at 102 dilution was 26.33 cfu g-1 which increased to 28.33 cfu g-1. This suggests that organic fertilization module (jeevamrit @ 20 ml/plant as drenching at 30 days interval) can act as an alternative for chemical fertilizers in consideration to the low input cost along with improving soil health and have the potential to contribute to better financial outcomes. It can also be concluded that among the different genotypes tested, ‘Bizet’ performed best under organic fertilization module with highest b:c ratio of 2.38. However, under inorganic fertilization module, ‘Bizet’ and ‘Raggio-de-Sole’ (b:c ratio of 2.02) performed better over the rest of the genotypes.

    NUTRITIONAL STUDIES IN POTTED FUCHSIA (Fuchsia x hybrida
    (UHF,NAUNI, 2023-11-01) RAHUL NEGI; JASBIR SINGH WAZIR
    ABSTRACT A greenhouse experiment entitled “Nutritional studies in potted Fuchsia (Fuchsia x hybrida)” was carried out at the Regional Horticultural Research and Training Station, Mashobra, Shimla (H.P.) for two consecutive years during 2021-2022. Potted plants were placed on benches under the greenhouse condition in a completely randomized design (CRD). There were 13 treatments with three replicates each (10 plants per replicate) i.e., Unfertilised control, 75% NPK through chemical fertilizers (Urea, SSP, and MOP), 100% NPK through chemical fertilizers (Urea, SSP, and MOP), 125% NPK through chemical fertilizers (Urea, SSP, and MOP), 75% N through Vermicompost on N equivalence basis, 100% N through Vermicompost on N equivalence basis, 125% N through Vermicompost on N equivalence basis, 75% N through Ghanjeevamrit on N equivalence basis + Jeevamrit (10%), 100% N through Ghanjeevamrit on N equivalence basis + Jeevamrit (10%), 125% N through Ghanjeevamrit on N equivalence basis + Jeevamrit (10%), 75% N through Ghanjeevamrit on N equivalence basis + Jeevamrit (15%), 100% N through Ghanjeevamrit on N equivalence basis + Jeevamrit (15%), and 125% N through Ghanjeevamrit on N equivalence basis + Jeevamrit (15%). After two years of planting nutritional treatment consisting of 125% N through Ghanjeevamrit on N equivalence basis + Jeevamrit (15%) resulted in maximum plant height (71.79 cm), plant spread (73.54 cm), plant size (72.66 cm), length of primary branch (53.86 cm), pot presentability (84.33 score), organic carbon content (2.25%), and available nitrogen (349.22 kg ha-1). Whereas, nutritional treatment consisting of 125% NPK through chemical fertilizers (Urea, SSP, and MOP) was observed best with respect to the number of secondary branches per plant (87.20), duration of flowering (231.22 days), number of flowers per plant (131.82), EC of growing media (0.867 dS m-1), available phosphorus (316.80 kg ha-1), available potassium (760.28 kg ha-1), and available sulphur (242.68 ppm). However, after two years of planting nutritional treatments did not have any significant effect on the number of primary branches per plant, number of leaves per plant, number of days taken to bud formation, the number of days taken to flowering, diameter of petal, diameter of sepal, length of flower stalk, growing media pH, exchangeable calcium and exchangeable magnesium.
