Abstract

The present study was conducted during winter (November‑December, 2022) in Jasmine growing area of Huvina Hadagali Taluk, Vijayanagara District to assess the soil micronutrient status in Jasmine growing area and analysed for their fertility parameters. A total of 60 soil samples were collected, of which 30 surface (0‒20 cm) and 30 subsurface (20‒40 cm) soil depths covering six villages namely Huvinahadagali, Hanakanahalli, Vinobhanagara, Meerakornahalli, Devagondana-halli and Thippapura. In surface soil, available micronutrients boron, zinc, iron, copper and manganese ranged from 0.45 to 1.28, 0.24 to 0.98, 1.17 to 7.90, 0.30 to 3.76 and 2.44 to 22.52 mg kg-1, respectively. Mean soil pH was 7.96, mean soluble salt was 0.27 dS m-1 and soil organic carbon ranged from 2.40 to 6.80 g kg-1. In subsurface soil, available micronutrients boron, zinc, iron, copper and manganese ranged from 0.36 to 1.09, 0.16 to 0.80, 0.96 to 6.76, 0.16 to 2.72 and 1.84 to 20.86 mg kg-1, respectively. Mean soil pH was 8.06, mean soluble salt was 0.32 dS m-1 and soil organic carbon ranged from 1.60 to 6.00 g kg-1. The results showed that depending on the nutrient nature, their concentration was either found in the range of deficit, or sufficient or in excess due to poor nutrient management practices like continuous use of chemical fertilizers and less use of organics which results in poor soil fertility leading to low yield and low quality of Jasmine flowers.
