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.)

ThesisItem Open Access EFFECT OF DRIP IRRIGATION LEVELS AND MULCHES ON BROCCOLI (Brassica oleracea L. var. italica) YIELD IN MID HILL ZONE OF HIMACHAL PRADESH(UHF Nauni, 2024-01-10) Divyansh Miahas; Ghanshyam AgrawalThe present study entitled “Effect of drip irrigation levels and mulches on Broccoli (Brassica oleracea L. var. italica) yield in mid hill zone of Himachal Pradesh” was conducted at research farm, Department of Soil Science and Water Management, Nauni - Solan during 2022-2023. The seven treatments were as follows: 100% ETc + Grass mulch (I1M1), 80% ETc + Grass mulch (I2M1), 60% ETc + Grass mulch (I3M1), 100% ETc + Pine needle mulch (I1M2), 80% ETc + Pine needle mulch (I2M2), 60% ETc + Pine needle mulch (I3M2) and Control - surface irrigation with 4 cm at 10 days interval as practiced by farmers and no mulch (I0M0), with three replication in randomized block design having each plot size of 2.25 m×1.80 m and spacing 45 cm×45 cm. The treatment I1M1 recorded higher soil moisture content than other treatments at both soil depths (0-15 cm and 15-30 cm). The average minimum and maximum soil temperatures were recorded highest in I3M1 and I0M0, respectively at both soil depths 5 cm and 10 cm. The maximum available N, P and K were found in I2M1 at both soil depths (0-15 cm and 15-30 cm). The highest bacterial count, fungi count and actinomycetes count were recorded under I2M1 at both soil depths (0-15 cm and 15-30 cm). The maximum plant height (51.10 cm), yield (242 q ha-1), net returns (Rs 3.51 Lakh ha-1), B:C ratio (3.64), minimum days to marketable maturity (102.00) and high water use efficiency (20.46 q ha-1 cm-1) were obtained under I2M1. Hence, I2M1 (80% ETc + Grass mulch) is considered as most efficient and cost effective irrigation treatment among all treatments. The study has led to a conclusion that for maximizing growth and yield of broccoli in mid hill zone of Himachal Pradesh, irrigation schedule I2 (80% ETc) with M1 (Grass mulch) i.e. I2M1 having 11.83 cm as crop water requirement through drip irrigation could be the best.ThesisItem Open Access STUDIES ON THE EFFECT OF NATURAL FARMING PRACTICES ON PRODUCTIVITY OF TOMATO (Solanum lycopersicum L.)(UHF,NAUNI, 2023-11-30) Charu Sharma; Upender SinghThe present investigation, entitled "Studies on the effect of natural farming practices on productivity of tomato (Solanum lycopersicum L.) was carried out at SPNF block in year 2022-23, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan. The experiment was laid out in Randomised Block Design on tomato cv. Solan lalima with intercrops bean cv. Contender and brinjal cv. Pusa purple long consisting of 9 treatments and 3 replication viz., T1 (1.0 t/ha Ghanjeevamrit + Jeevamrit @ 20%), T2 (1.0 t/ha Ghanjeevamrit + Jeevamrit @30%), T3 (1.5 t/ha Ghanjeevamrit + Jeevamrit @ 20%), T4 (1.5 t/ha Ghanjeevamrit + Jeevamrit @30% ), T5 (2.0 t/ha Ghanjeevamrit + Jeevamrit @ 20%), T6 (2.0 t/ha Ghanjeevamrit + Jeevamrit @30%), T7 (3.0 t/ha Ghanjeevamrit + Jeevamrit @ 20%), T8 (3.0 t/ha Ghanjeevamrit + Jeevamrit @30%), T9 (Absolute Control). The results of investigation revealed that the application of different formulations not only significantly increased the soil organic carbon content, nutrient uptake, growth, yield, and quality parameters of tomato but also increased soil macro as well as micronutrients along with soil microbial count. The increase in soil and growth parameters by the treatment T8 (3.0 t/ha Ghanjeevamrit + Jeevamrit @30%) was followed by T7 (3.0 t/ha Ghanjeevamrit + Jeevamrit @ 20%) whereas maximum B:C ratio of 2.81 was recorded under treatment T7 (3.0 t/ha Ghanjeevamrit + Jeevamrit @ 20%). Application of 3.0 t/ha Ghanjeevamrit + Jeevamrit @ 20% @ 14 days interval + (six foliar application of Jeevamrit) JM may be recommended as most effective nutrient module for tomato cultivation and sustaining soil health.ThesisItem Open Access NUTRITIONAL SURVEY OF CHERRY ORCHARDS IN SHIMLA DISTRICT OF HIMACHAL PRADESH(UHF,NAUNI, 2023-10-25) CHANDER PRABHA; M L VERMAABSTRACT Shimla district of Himachal Pradesh, well known for quality cherry production in India was selected for the study. Soil and leaf samples from 30 representative cherry orchards were collected across three administrative blocks, namely Theog, Narkanda and Jubbal-Kotkhai (10 villages from each block) of the district. Soil samples were analysed for their physico-chemical properties and available nutrients status. Soil texture varied from sandy loam to sandy clay loam and soil pH was slightly acidic to nearly neutral. EC values were in safe limits (< 0.8 dS m-1). The organic carbon content was high. Among DTPA extractable micronutrients, soils were mostly deficient in Zn and sufficient in Fe, Mn and Cu. Considering nutrient index value <1.67, 1.67 to 2.33 and > 2.33 for low, medium and high nutrient status of soils, respectively, the soils of the study area were found to be in the category of low for N; medium for Zn; and high with P, K, S, Mn, Cu and Fe. All the nutrients showed decreasing trend with increasing soil depth. Leaves registered sufficient N and K content, whereas, P was high in majority of leaf samples. Leaf S, Fe, Mn and Cu were under sufficient ranges, whereas, Ca and Mg were excess/high. Zn deficiency was reported in majority of leaf samples. Surface soil pH was significantly and positively correlated with available Ca and Mg and had a significantly negative correlation with available Fe. Soil organic carbon was positively correlated with almost all the nutrient elements of soil and leaf. Significantly positive relationship was found between soil and leaf nutrients. A critical appraisal of correlation co-efficient among soil and leaf nutrients revealed that plants absorb nutrients from both surface as well as sub-surface soils. The variations in soil properties and nutrient status in cherry orchards indicate need for adopting integrated and soil test based nutrient management in sustainable manner.ThesisItem Open Access STRUCTURAL AND FUNCTIONAL DIVERSITY OF BACTERIAL COMMUNITY ASSOCIATED WITH APPLE RHIZOSPHERE OF SPITI VALLEY(UHF,NAUNI, 2023-10-20) ANANNYA B; ANJALI CHAUHANABSTRACT The present investigation, titled "Structural and Functional Diversity of Bacterial Community Associated with Apple Rhizosphere in Spiti Valley," promises to pave the way for exploring the microbial community structure in various farmlands situated in the high-altitude cold desert of Spiti Valley. The study involved collecting soil samples from the apple rhizosphere at six different sites: Tabo, Lari, Hurling, Kurith, Needang, and Poh. A comprehensive analysis was conducted on soil texture and chemical properties, including pH, Electrical conductivity, and Organic carbon content. Moreover, macronutrients (NPK) and micronutrients (DTPA-extractable Cu, Fe, Zn, Mn) were also assessed. The research yielded intriguing findings as the isolates demonstrated positive traits like phosphorus solubilization with a range of 101 to 280.53%, siderophore production with an efficiency of 67.32 to 267.3%, and indole-3-acetic acid regulation ranging from 13.7 to 73.03μg/ml, indicating potential plant growth-enhancing properties. Additionally, these isolates exhibited antagonistic behaviour against pathogenic organisms like Fusarium oxysporum, Dematophora nectarix and Rhizoctonia solani, suggesting their role in plant health and disease suppression. By employing metagenomic analysis, the study offered valuable insights into the presence of non-culturable bacteria, providing a deeper understanding of the microbial diversity in the region. The analysis identified an impressive range of taxa, including 43 phyla, 128 classes, 317 orders, 492 families, 833 genera, and 1532 species. This research represents a significant advancement in the knowledge of both culturable and non-culturable bacteria thriving in the extreme conditions of high-altitude cold deserts in the trans-Himalayan region.ThesisItem Open Access PRODUCTIVITY OF CAULIFLOWER (Brassica oleracea L. var. botrytis L.) AS INFLUENCED BY THICKNESS OF SYNTHETIC MULCH(UHF,NAUNI, 2022-12) KOMAL; SPEHIA, R SABSTRACT The present investigation entitled “Productivity of cauliflower (Brassica oleracea L. var. botrytis L.) as influenced by thickness of synthetic mulch” was conducted during 2021-22 at experimental farm of the Department of Soil Science and Water Management, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, with the objectives to study the effect of thickness of synthetic mulches on soil hydrothermal regimes, nutrient uptake, yield and economics of cauliflower production. Research trial comprised of 5 mulch thickness viz. 20, 25, 30, 50 and 100 micron with combination of silver or black colour upwards in addition to control. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Thickness of synthetic mulch improved soil hydrothermal regimes, physical, chemical and biological properties, NPK uptake, growth and yield of cauliflower over control. Mulch increased the minimum soil temperature by 1.5 ℃ and 1.4 ℃ over control at 0.05 m and 0.10 m, respectively, while there was no significant effect of mulch on maximum soil temperature. Soil moisture content under mulch increased by 36 % over control. Significantly maximum soil viable microbial count, NPK content, Sulphur content in leaf curd and root of cauliflower, dry matter yield of leaf and root of cauliflower and NPK, Ca, Mg, S uptake in leaf, curd and root of cauliflower plant were recorded under 100μ, black/silver polyethylene mulch (T7) but were statistically at par with treatment T8 (50μ, black/silver polyethylene mulch), T6 (20μ, silver/black polyethylene mulch), T5 (25μ, silver/black polyethylene mulch) and T4 (30μ, silver/black polyethylene mulch). Thickness of synthetic mulch had a distinct effect on growth and yield of cauliflower. Treatment T7 (100μ, black/silver polyethylene mulch) increased the yield by 33% over control but was statistically at par with treatments T8 (50μ, black/silver polyethylene mulch), T6 (20μ, silver/black polyethylene mulch), T5 (25μ, silver/black polyethylene mulch) and T4 (30μ, silver/black polyethylene mulch). Highest B:C ratio (1.70:1) was recorded under treatment T6 (20μ, silver/black polyethylene mulch) as the cost of cultivation was almost half of that of treatment T7 (100μ, black/silver polyethylene mulch), which recorded B:C ratio of 0.44:1. Therefore, 20μ, silver/black polyethylene mulch can be recommended for late group cauliflower production.ThesisItem Open Access STUDIES ON RHIZOBACTERIA ASSOCIATED WITH GUAVA UNDER MID HILLS OF HIMACHAL PRADESH(UHF,NAUNI, 2022-12) JHANGTA, ABHISHEK; CHAUHAN, ANJALIABSTRACT Guava (Psidium guajava) is one of the major tropical crops grown in India and around the world. Guava is a member of the Myrtaceae family and is also known as the Apple of the Tropics. In Himachal Pradesh, guava is grown in district Bilaspur, Kangra, Mandi, Hamirpur and Una. It has a reasonable quantity of calcium and is an inexpensive source of vitamin C. Guava is a good source of dietary fiber and pectin, also a strong source of ascorbic acid. Interest in the beneficial rhizobacteria associated with horticultural crops has increased recently and several studies clearly demonstrated the positive and beneficial effects of PGPR on growth and yield of different crops at different environment under variable ecological conditions. The pH, EC and OC values of the collected samples varied from (6.67 to 7.93), (0.11 to 0.37 dSm-1) and (0.42 to 1.03%). The N, P and K values of the collected samples varied from (243.60-389.80 kg ha-1), (22.20 to 54.60 kg ha-1) and (144.00 to 389.14 kg ha-1). The maximum N, P and K was recorded in district Kangra. In case of rhizospheric and endorhizospheric bacterial population of guava and their characterization for efficient plant growth promoting traits, total of 75 bacterial isolates were selected. Out of 75 isolates, 40 isolates were P- solubilizers, nitrogen fixers and IAA producers and 38 were siderophore producers. From the total selected bacteria, only two BS6 and KS24 showing promising plant growth promoting traits were characterized by biochemical and molecular identification. BS6 and KS24 were gram positive, rod shaped and showed amplifcation at ~1400bp by 16S rDNA.Therefore, identity of the strains was given as Bacillus subtilis for strain BS6 and Bacillus licheniformis for strain KS24 respectively, and can further be exploited as bioinoculant for field studies.ThesisItem Open Access NUTRITIONAL SURVEY OF CAULIFLOWER GROWING AREAS IN THEOG BLOCK OF SHIMLA DISTRICT IN HIMACHAL PRADESH(UHF,NAUNI, 2022-11) BHANOT, LOKESH; AGRAWAL, GHANSHYAMABSTRACT The present study was carried out during 2021-22 in Theog block of Shimla district, Himachal Pradesh with the objective to study the soil and leaf nutrient contents of cauliflower and to establish the relationship among soil characteristics and leaf nutrients contents. The total no. of 25 sampling sites were selected in the study area. Total 50 no. of soil samples were collected at two depths i.e., surface (0-15 cm) and subsurface (15-30 cm), and 25 no. of leaf samples were collected from 25 identified sampling sites before the harvesting of crop i.e., in the month of March – April. The collected soil and leaf samples were analysed for different soil physical, chemical and biological properties such as soil texture, bulk density, particle density and porosity, pH, electrical conductivity, soil organic carbon and available N, P, K, exchangeable Ca, Mg, available SO4 --S and DTPA extractable Zn, Fe, Cu, Mn nutrients, microbial counts and biomass. The leaf samples were analysed for nutrient such as N, P, K, Ca, Mg, S, Zn, Fe, Cu and Mn. On the basis of soil texture classes, the soil of different cauliflower growing areas varied from sandy loam to loam and bulk density is <1.6 g cm-1, hence the soils are less compact and do not interfere with root growth. The soil was slightly acidic to neutral in soil reaction. The soils are in safe limits of electrical conductivity as the values were < 0.8 ds m-1. Soil organic carbon was found to be medium in both layers. The available N was low in surface and subsurface layers. The available K and DTPA extractable Zn was found to be medium range. Whereas P, Ca, Mg, S, Fe, Mn and microbial count and biomass was high. The leaf nutrient status indicates that all the nutrient N, P, K, Ca, Mg, S, Zn, Fe, Cu, Mn were in sufficient amount in the leaf and no leaf nutrient deficiency was observed. Available N, P and K showed highest positive significant correlation with available P, N and available K. Highest positive significant correlation of available SO4 --S, exchangeable Ca and Mg was observed with K and Mg. Negative correlations of all the micronutrients were observed with soil pH Highest positive significant correlation of Zn, Fe, Cu and Mn was found with DTPA-extractable Fe and Zn. The results revealed that the addition of FYM along with N fertilizers will not only pave the way for achieving sustainable crop productivity but will also maintain the soil healtThesisItem Open Access EFFECT OF IRRIGATION REGIMES AND SOWING METHODS ON THE PRODUCTIVITY OF RADISH (Raphanus sativus L.(UHF,NAUNI, 2022-11) SILORI, SUSHMITA; SHARMA, J CABSTRACT Present investigation entitled “Effect of irrigation regimes and sowing methods on the productivity of radish (Raphanus sativus L.)” was carried out in the Department of Soil Science and Water Management, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2021-22. The study focused on ascertaining the effect of irrigation regimes and sowing methods on growth, yield, nutrient content and their uptake, water requirement and water use efficiency in radish. Eight treatment combination comprising four irrigation schedules i.e. 3 cm irrigation at IW/CPE ratio 1.2 (I1), 1.0 (I2), 0.8 (I3), 0.6 (I4) and two sowing methods i.e. ridge bed (S1), flat bed (S2) were replicated thrice in a randomized block design (factorial) in plot size of 3m × 2 m and spacing of 30 cm × 10 cm. The irrigation schedule I1 and I2 recorded significantly higher soil moisture content, nutrient content, uptake and growth of radish over I4. Significantly highest yield of radish was recorded under I1 (296.1 q ha-1) schedule. Irrigation schedule I3 exhibited highest WUE (171.86 kg ha-1 mm-1) with 13.6 cm of total water requirement followed by I2 and lowest (148.05 kg ha-1 mm-1) under I1 schedule. Among sowing methods significantly higher growth and yield of radish was found under S1 (264.2 q ha-1). Treatment combinations I1S1 and I2S1 recorded higher yield and showed an increase of 50.29 and 36.22 per cent over I4S2. Based on B:C ratio, treatment combination I1S1 was found to be most economical (2.99:1) followed by I2S1 (2.66 :1). Since the yield and B:C ratio, was highest under I1S1 this could be considered as most appropriate treatment combination for obtaining higher growth and yield of radish crop.ThesisItem Open Access STUDY ON PRODUCTIVITY OF CARROT UNDER VARIOUS SOWING METHODS AND IRRIGATION LEVELS(UHF,NAUNI, 2022-11) PRIKXIT; SHARMA, J CABSTRACT Present investigation “Study on productivity of carrot under various sowing methods and irrigation levels” was conducted on carrot var. Pusa Yamdagini in Department of Soil Science and Water Management, Dr. Y S Parmar University and Horticulture and Forestry, Nauni, Solan (HP). The study was focused on ascertaining the response of irrigation levels and sowing methods on growth, yield, water requirement, water use efficiency, nutrient content and their uptake in carrot. Eight treatment combinations comprising of four irrigation levels viz. 0.6 (I1), 0.8 (I2), 1.0 (I3) and 1.2 (I4) IW/CPE ratio and two sowing methods (S1: flat-bed and S2: ridge method) were replicated thrice in Randomised Block Design (Factorial) with plot size 3m × 2m and spacing of 30 cm × 10 cm. The irrigation level I4 and I3 recorded significantly higher soil moisture content, nutrient content, uptake and growth of carrot over I1. Maximum carrot yield (323.44 q ha-1) was recorded under I4 followed by I3 (305.52 q ha-1) and showed an increase of 77.78 (I4) per cent and 66.36 (I3) per cent over I1. Irrigation level I3 exhibited highest WUE (179.13 kg ha-1 mm-1) with total water requirement of 23.74 cm followed by I2 irrigation level. There was 37.01 and 30.78 per cent increase in WUE under I3 and I2 over I1, respectively. Treatment combinations S2I4, S2I3 and S1I4 increased the nutrient content in soil and plant which significantly increased the growth and yield of carrot. Treatment combination S2I4 was found to be most economical and revealed highest B:C ratio (2.96:1) followed by S2I3 (2.81:1). On the basis of B:C ratio, research findings revealed that ridge method of sowing with 1.2 IW/CPE irrigation level showed better results in terms of growth and yield of carrot.
