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.

    INTEGRATED NUTRIENT MANAGEMENT STUDIES IN ONION
    (UHF,NAUNI, 2019-12) NEGI, MANISHA; SHARMA, J C
    ABSTRACT The present investigation entitled “Integrated nutrient management studies in onion” was carried out at the Experimental Farm, Department of Soil Science and Water Management, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during rabi season of 2017-18 and 2018-19. Different combinations of organic and inorganic sources of nutrients were tried in the form of nine treatments viz. T1 (Absolute control), T2 (RD of FYM + NPK), T3 (5 % Jeevamrut), T4 (RD of FYM + NPK through FYM), T5 (RD of FYM + 5 % Jeevamrut), T6 (VC + RD of NPK through FYM), T7 (VC + 5 % Jeevamrut), T8 (50 % FYM + 50 % VC + RD of NPK through FYM) and T9 (50 % FYM + 50 % VC + 5 % Jeevamrut) in a plot of 2.25 × 1.20 m2 dimension. The experiment was laid out in a randomised block design (RBD) with three replications involving a spacing of 15 × 10 cm. The seedlings of onion cv. Nasik Red were planted on 27th November during 2017 and 1st November during 2018. The results revealed significantly highest post harvest fertility status of macronutrients (NPK) (386, 156.6 and 384.1 kg ha-1, respectively) and their uptake (122.5, 16.7 and 67.4 kg ha-1, respectively) was recorded under recommended INM practice i.e. 125 N: 75 P: 60 K kg ha-1 + FYM @ 250 q ha-1 (T2). The close scrutiny of purely organic module T6 (VC - equivalent to N content of recommended FYM + RD of NPK through FYM on N equivalent basis) showed it next best in values with respect to available NPK and their uptake. Similarly, significantly highest bulb and biological yield (295.5 and 441.9 q ha-1, respectively) and yield contributing component i.e. bulb size (19 cm²) as well as net income (4,74,812 ` ha-1) with a relatively higher B:C ratio (4.1:1) was recorded under recommended INM practice (T2). It was closely followed by purely organic module T4 (RD of FYM + RD of NPK through FYM on N equivalent basis) with regards to bulb and biological yield, yield contributing component, net income and B:C ratio. The plots fertilized with RD of FYM + RD of NPK through FYM on N equivalent basis has recorded only 13.6 per cent less bulb yield in comparison with recommended INM practice (T2). Therefore, the purely organic modules T4 (RD of FYM + RD of NPK through FYM on N equivalent basis) and T6 (VC - equivalent to N content of recommended FYM + RD of NPK through FYM on N equivalent basis) with on farm production of VC can be suggested for organic cultivation of onion.

    ABSTRACT The present investigation entitled “Effect of nitrogenous fertilizers on organic matter fractions and soil quality under apple cv. Vance Delicious” was conducted at Regional Horticultural Research and Training Station, Bajaura, Seobag (HP) during 2018-2019. There were 14 treatments comprising of different fertilizers and their combinations, replicated thrice in a Randomised Block Design under field conditions. Treatment details were as follows: T1 (control), T2 (urea), T3 (calcium nitrate), T4 (calcium cyanamide), T5 (urea + liming in October)), T6 (urea + liming in March), T7 (12:32:16 + urea), T8 (12:32:16 + calcium nitrate), T9 (12:32:16 + calcium cyanamide), T10 (15:15:15 + urea), T11 (15:15:15 + calcium nitrate), T12 (15:15:15 + calcium cyanamide), T13 (50% urea through soil application + 50% through foliar application and T14 calcium nitrate + urea + liming. Different nitrogenous fertilizers were applied on N equivalence basis as perthe standard recommendations. Soil sampling after two years of continuous application was done at two depths viz., 0-15 cm and 15-30 cm. The lowest value for bulk density for 0-15 cm depth was recorded in T14 (1.01 g cm-3), while that for the 15-30 depth cm was found under thesame treatment i.e. T14 (1.09 g cm-3). The maximum particle density for 0-15 cm depth (2.64 g cm-3) and porosity (61.25%) were also recorded with T14 comprising of the application of calcium nitrate + urea + liming. The soil pH for 0-15 cm depth was recorded minimum with the application of T8, whereas, for 15-30 cm depth it was recorded minimum with T10. The highest organic carbon for the upper depth was recorded under treatment T7 (15.93 g kg-1), while for the 15-30 cm depth the highest organic carbon content was recorded under treatment T8 (14.40 g kg-1). The maximum labile carbon content for the 0-15 cm soil depth was found under the application of treatment T13 with a value of 0.44 g kg-1, whereas, for the 15-30 cm soil depth the maximum labile carbon content was observed under the application of treatment T3 (0.32 g kg-1). Maximum N (386.77 kg ha-1) and P (88.11 kg ha-1) were observed under T6, while K was maximum (538.35 kg ha-1) was under T14. The highest total microbial count for 0-15 cm soil depth and 15-30 cm soil depth was recorded with the application of same treatment i.e. T14with the values of 139.75 × 105 cfu g-1 soil and 128.41 × 105 cfu g-1 soil, respectively. The highest value of microbial biomass carbon for the 0-15 cm and for 15-30 cm were also observed maximum under the same treatment i.e. T6 with values of 801.85 µg g-1 soil and 674.99 µg g-1 soil, respectively. The highest value of dehydrogenase enzyme activity for the 0-15 cm soil depth was observed under the T6 (58.40 µg TPF g-1 soil 24 hr-1), whereas, for the 15-30 cm soil depth the highest value of dehydrogenase enzyme activity was observed under T12 (47.67 µg TPF g-1 soil 24 hr-1). The light fraction organic matter (399.35 g C kg-1) and particulate organic matter (49.03 g kg-1) were recorded maximum under treatment T6 for the 0-15 cm soil depth. The fruit yield was found to be maximum (75.32 kg tree-1) was obtained with the treatment T14. The soil quality index was also recorded highest with the application of treatment T6 having a value of 4.260.

    EFFECT OF FIRE ON MINERALIZATION OF SOIL ORGANIC MATTER
    (UHF,NAUNI, 2019-08) VISHVAMITERA, SAKSHI; SHARMA, UDAY
    ABSTRACT The investigation entitled “Effect of fire on mineralization of soil organic matter” was carried out at five sites located at Dr. Y.S. Parmar University of Horticulture and Forestry Nauni, Solan, Himachal Pradesh, during the year 2018-2019, with an aim to determine the effect of fire on nitrogen mineralization, organic carbon and microbial biomass carbon. The comparison of four land uses (viz. Forests, grasslands, scrubland and unburnt chir pine) was made with respect to the studied parameters. A controlled fire was made in all the land uses in March, 2018. Soil samples (0 to 5 cm, 5 -10 cm and 10-15 cm depths)from a plot size of 50m × 50m for each land use at each site, were collected at monthly intervals upto March, 2019. The soils of the area had bulk density varying from 1.11- 1.16 Mg m-3 and pH varying from 5.89-6.13. The available N, P and K varied from 170.2-180.2, 23.9-29.5 and 271.7-321.5 kg ha-1, respectively. The ammonical- N content of 0-5 cm depth in forest soils was higher (105.11 mg kg-1) which increased upto August and thereafter declined. The content also decreased with depth. The nitrate-N of 0-5 cm depth was maximum (65.64 mg kg-1) in the forest land use compared to the minimum in unburnt chir pine site (49.78 mg kg1 ). The nitrate-N content varied with land use in the order Forest > Grassland > Scrubland > Unburnt chir pine site. The net mineralization in the 0-5 cm depth was maximum (30.9 mg kg-1) in forest landuse. The maximum rate of mineralization (0.09 mg N kg-1day-1) was in sub-surface layers of forest and for surface layers of grassland, after the fire. Organic carbon was in the order: grasslands (1.30 per cent) > unburnt site (1.29 per cent > scrubland (1.22 per cent) > forest (1.16 per cent). The soil microbial biomass carbon also varied from 155.5172.9 μg g-1 soil in forest, 131.3-147.1 μg g-1 soil in grassland, 130.4-145.1 μg g-1 soil in scrubland and 174.2-186.4 μg g-1 soil in non- fire site. In general the forest fires ha

    EFFECT OF MULCH ON SOIL PROPERTIES AND YIELD OF TOMATO (Solanum lycopersicum L.)
    (UHF,NAUNI, 2019-02) BAJIA, RAJESH; AGRAWAL, GHANSHYAM
    ABSTRACT The present study entitled “Effect of mulch on soil properties and yield of tomato (Solanum lycopersicum L.)” was conducted at the research farm of the Department of Soil Science and Water Management, Nauni, Solan during the years 2017 and 2018 with seven treatments viz. T1-BM, T2-SM, T3-TM, T4-MM, T5-GM, T6-PM and T7-NM with three replications in randomized block design with plot size of 4m×2m and spacing 90cm×30cm. Black mulch increased moisture (20.34 and 19.08%) at surface and (21.59 and 18.87 %) at subsurface depths as compared to no mulch in year 2017 and 2018, respectively. The transparent mulch increased maximum and minimum soil temperatures as compared to other treatments at both 15 cm and 30 cm soil depths. The porosity was found the highest (51.74 and 51.15 %) under grass mulch, which was attributed to higher organic carbon contents (20.35 and 18.35 g kg-1) and lower bulk density (1.27 and 1.29 Mg m-3) at 0-15 and 15-30 cm soil depths, respectively. The plant available water was found significantly maximum (16.45 and 15.63 %) under grass mulch at 0-15 and 15-30 cm soil depths, respectively. The availability of macro-nutrients (N, P and K) in soil was recorded significantly higher under the black polyethylene mulch. The highest plant height (172.2 cm), fruit per plant (28.33), fruit weight (62.2 g), fruit diameter (5.76 cm) and yield (63.6 t ha-1) were observed in T1-BM. The yield under black mulched treatment was 40.08 per cent higher than the control. The maximum water use efficiency (1.85 t ha-1 cm-1) was recorded under T1-BM which was 44.53 per cent higher as compared to no mulch treatment. The maximum net return per hectare 9.46 lakhs with higher B:C ratio (4.58) was found under T1-BM. The study has led to a conclusion that maximizing water use efficiency, yield and net economic returns of tomato in mid hill region of Himachal Pradesh, T1-BM i.e. black polyethylene mulch could be the best.

    (UHF,NAUNI, 2019-02) THAKUR, PRIYA; KUMAR, PRADEEP
    ABSTRACT Present investigation entitled “Effect of organic manurs, PGPR and mulches on soil properties and growth of apricot (Prunus armeniaca L.) cv. New Castle” was carried out in the Department of Soil Science & Water Management, Dr YS Parmar University of Horticulture & Forestry, Nauni, Solan (HP) during 2017 and 2018 with an aim to evaluate the effect of different organic nutrient sources, PGPR and mulches on soil properties, leaf nutrient content, weed incidence and growth parameters of apricot. The experiment was laid out in a randomized block design with three replications comprising nine treatments viz. T1 (Grass Mulch(GM)+RD FYM+RD NPK through FYM on N equivalence), T2 (GM+RD FYM+RD NPK through VC on N equivalence), T3 (GM+RD FYM+RD NPK through VC on N equivalence +PGPR), T4 (Black Polythene Mulch (BPM)+RD FYM+RD NPK through FYM on N equivalence), T5 (BPM+RD FYM+RD NPK through VC on N equivalence), T6 ((BPM+RD FYM+RD NPK through VC on N equivalence +PGPR), T7 (Mulch Mat) MM+RD FYM+RD NPK through FYM on N equivalence), T8 (MM+RD FYM+RD NPK through VC on N equivalence), T9 (MM+RD FYM+RD NPK through VC on N equivalence +PGPR). Results revealed that Mulch Mat treatments recorded highest soil moisture followed by Black Plastic Mulch and Grass Mulch. Mulches Mat increased the minimum soil temperature while Black plastic mulch recorded highest maximum temperature. Treatment T9 was found best with significantly maximum soil and leaf NPK content, microbiological properties and almost weeds free conditions in plant basin area. Plant growth parameters (annual shoot growth, tree height, trunk girth and tree spread) were also recorded higher under T9.
