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 NUTRIENT SOURCES ON SOIL PROPERTIES AND PRODUCTIVITY OF KIWIFRUIT (Actinidia deliciosa cv. ALLISON)
    (UHF,NAUNI, 2021-07) ASHOK KUMAR; KAUSHAL, RAJESH
    ABSTRACT The present investigation entitled “Effect of nutrient sources on soil properties and productivity of kiwifruit (Actinidia deliciosa cv Allison)” was conducted on 6 years old kiwifruit vines cultivar ‘Allison’ at a spacing of 4.0 m × 6.0 m for two consecutive years 2018-19 and 2019-20 at experimental block of Department of Fruit Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out in triplicate in Randomized Block Design with 8 treatments under three farming systems viz., Chemical Fertilizer Based System (CFBS), Organic Farming Based System (OFBS) and Subhash Palekar’s Natural Farming System (SPNFS). The eight treatments are T1 (N: 800 g, P2O5: 600 g, K2O: 800 g + 40 kg FYM per vine) under CFBS, four treatments under OFBS namely T2 {100% Recommended dose of N (RDN) through vermicompost (VC) and poultry manure (PM) on 50: 50 basis + 40 kg FYM per vine}, T3 (90% RDN through VC and PM on 50: 50 basis + 40 kg FYM per vine) and T4 (80% RDN through VC and PM on 50: 50 basis + 40 kg FYM per vine) and T5 (70% RDN through VC and PM on 50: 50 basis + 40 kg FYM per vine) and three treatments under SPNFS namely T6 {15 liters of Jeevaamrit (JM) + 3 kg of Ghana Jeevaamrit (GJ) + 40 kg FYM per vine}, T7 (22.5 liters of JM + 3 kg of GJ + 40 kg FYM per vine) and T8 (30 liters of JM + 3 kg of GJ + 40 kg FYM per vine). The maximum leaf area (158.1 cm2), leaf area index (4.36), chlorophyll index, photosynthetically active radiation was found with the application of 30 liters JM + 3 kg GJ + 40 kg FYM (T8) of SPNFS) followed T2 treatment of OFBS over T1 under CFBS. The treatments T2 and T8 observed comparable fruit yield, high percent proportion of A-grade fruits, lower fruit length and weight and comparable fruit diameter over chemical fertilizer treatment. Best fruit quality parameters namely; TSS content (16.87 ºB), total sugars (11.77%), reducing sugars (8.31%), non-reducing sugars (3.28%) and ascorbic acid (81.55 mg/100g) were recorded with treatment T2. The T2 treatment also witness maximum soil organic carbon (31.23 g kg-1), available soil N (365.8 kg ha-1), available soil P (104.6 kg ha-1), available soil K (449.1 kg ha-1), DTPA extractable Cu (3.63 mg kg-1), Mn (14.92 mg kg-1) and Zn (4.23 mg kg-1) in surface soil layers. However, T8 treatment of SPNFS estimated manyfold increase in bacterial (200 cfu × 105 g-1), fungal (25 cfu × 103 g-1), actinomycetes count (22 cfu × 103 g-1), dehydrogenase activity (35.8 μg TPF g-1 hr-1) and acid phosphatase activity (119.8 μg PNP g-1 hr-1) in addition to soil physico-chemical properties. Maximum benefit: cost ratio of 12.36:1 was obtained in T1 followed by 12.22:1 in T8 treatment while organic treatment T2 enumerated much lower benefit cost of 4.17:1 despite improvement in soil quality parameters and comparable yields. This might be due to the high cost of organic inputs viz. VC and PM. Finally, it is concluded that the treatment comprising application of 30 litres JM + 3 kg GJ (3 equal splits in end of January, February and April) + 40 kg FYM per vine was found to be better option instead of chemical fertilizers to the Allison cultivar of kiwifruit under mid-hill conditions of Himachal Pradesh to achieve comparable yields and nearly equal returns accompanied by maintaining soil healt
