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.

    EFFECT OF INTEGRETED NUTRIENT MANAGEMENT ON GROWTH, YIELD AND FRUIT QUALITY OF APRICOT (Prunus armeniaca L.)
    (UHF,NAUNI, 2017) ANSHUL, KUMAR; SHARMA, D.D.
    ABSTRACT The present investigations entitled “Effect of integrated nutrient management on growth, yield and fruit quality of apricot (Prunus armeniaca L.)” was carried out in the experimental orchard at Horticultural Research and Training station and Krishi Vigyan Kendra (HRTS & KVK), Kandaghat, Solan (H.P.) during 2015-2017 on full grown (20 years) apricot trees of New Castle cultivar, planted at a distance of 5 × 5 m. The experiment was laid out in randomized block design (RBD). The experiment consisted of 14 treatments viz. recommended dose of fertilizers, Jeevamrut ( 3 applications at one month interval ), FYM + Azotobacter + PSB, Vermicompost + Azotobacter + PSB, 100 % N (CN) + 0 % N (Urea) + Azotobacter + PSB + FYM, 75 % N (CN) + 25 % N (Urea) + Azotobacter + PSB + FYM, 50 % N (CN) + 50 % N (Urea) + Azotobacter + PSB + FYM, 25 % N (CN) + 75 % N (Urea) + Azotobacter + PSB + FYM, 0 % N (CN) + 100 % N (Urea) + Azotobacter + PSB + FYM, 100 % N (CN) + 0 % N (Urea) + Azotobacter + PSB + Vermicompost, 75 % N (CN) + 25 % N (Urea) + Azotobacter + PSB + Vermicompost, 50 % N (CN) + 50 % N (Urea) + Azotobacter + PSB + Vermicompost, 25 % N (CN) + 75 % N (Urea) + Azotobacter + PSB + Vermicompost and 0 % N (CN) + 100 % N (Urea) + Azotobacter + PSB + Vermicompost, each treatment was replicated thrice. The results revealed that the application of different integrated nutrient sources in apricot trees significantly influenced the plant vegetative characters, fruiting characters, physico-chemical characters, leaf nutrient status, soil nutrient status and benefit to cost ratio. Maximum increase in tree height (31.73 %), tree spread (34.22 %), tree volume (38.84 %), annual shoot extension growth (93.91 %) was recorded with the application of treatment T11 consisting of 75 % N (CN) + 25 % N (Urea) + Azotobacter + PSB + Vermicompost. Maximum increase in tree trunk girth (6.82 %), highest leaf chlorophyll content (3.00 mg/g fresh weight), leaf area (58.29 cm), fruit set (61.00 %), total yield (61.9 kg/tree) was recorded in treatment T12 consisting of 50 % N (CN) + 50 % N (Urea) + Azotobacter + PSB + Vermicompost. However, fruit TSS, total sugars, reducing and non-reducing sugars were significantly higher in T7 [50 % N (CN) + 50 % N (Urea) + Azotobacter + PSB + FYM] which were statistically at par with T12. Regarding nutrient status, the highest leaf N (2.95 %), leaf K (2.60 %), soil N (386.33 kg/ha), soil P (51.00 kg/ha) and soil organic carbon content (1.81 %) was recorded in T12 [50 % N (CN) + 50 % N (Urea) + Azotobacter + PSB + Vermicompost]. Net return and profit over RDF were found maximum in T12. Hence T12 [50 % N (CN) + 50 % N (Urea) + Azotobacter + PSB + Vermicompost] was found to be the best treatment in respect of fruit size, fruit yield, fruit quality, leaf and soil nutrient status, net return and profit over RDF followed by T7 [50 % N (CN) + 50 % N (Urea) + Azotobacter + PSB + FYM].
