Silver King)” was conducted on 8 years old nectarine cultivar ‘Silver King’ at a spacing of 4.5 m x 4.5 m for two consecutive years 2020 and 2021 at the experimental farm of Department of Soil Science and Water Management, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out in a randomized block design with 12 treatments viz., T1-Recommended dose of nutrients (RDN) + 40 kg FYM-(control), T2- 100% RDN + dual inoculation with Azotobacter and PSB, T3-100% RDN + 10 kg vermicompost, T4- 100% RDN + 20 kg vermicompost, T5-75% RDN + 10 kg vermicompost, T6-75% RDN + 20 kg vermicompost, T7-75% RDN + 10 kg vermicompost + inoculation with Azotobacter, T8-75% RDN + 20 kg vermicompost + inoculation with Azotobacter, T9-75% RDN + 10 kg vermicompost + inoculation with PSB, T10-75% RDN + 20 kg vermicompost + inoculation with PSB, T11-75% RDN + 10 kg vermicompost + dual inoculation with Azotobacter and PSB, T12-75% RDN + 20 kg vermicompost + dual inoculation with Azotobacter and PSB. Soil properties viz., physical, chemical and biological properties were significantly influenced by integrated nutrient management practices. Leaf macro and micronutrient content were significantly higher in treatment T12. Plant parameters viz., plant height, trunk girth, annual extension growth and plant spread were also recorded maximum in treatment T12 . Maximum productivity (15.00 t/ha) and yield efficiency (0.317 kg/cm2) were recorded in T12 .Fruit quality parameters viz., fruit length, breadth, fruit weight, TSS, total sugars, reducing sugars, non-reducing sugars and minimum titratable acidity. were found under treatment T12. Finally, it is concluded that treatment comprising 75% RDN + 20kg vermicompost + Dual inoculation with Azotobacter and PSB (T12) was found to be most effective combination of integrated nutrient management application to nectarine under mid-hills of Himachal PradeshEnglishThesis
