Abstract
Sunflower (Helianthus annuus L.) is a photosensitive crop and is therefore grown in Kharif, Rabi and spring seasons. Rabi season is recommended for cultivation of sunflower. The crop has most important agronomic characteristics, such as resistance to drought and cold, with wide adaptability to different soil and climatic conditions. In the present study the physicochemical assessment of soil samples were collected randomly from the rhizosphere soil of Davangere region was carried out. Rhizosphere is a dynamic changing environment that differs from bulk soil both in physical and chemical properties. The physicochemical analysis of soil is based on the various parameters such as Soil texture, Soil moisture, pH, Moisture content, Electrical conductivity, Micro and macro nutrients in the rhizosphere soil samples were analysed. Six soil samples were collected from the different places of all the taluks of Davangere district results shows that, the values of pH range from 6.89 to 7.88, pH was found to vary from neutrality to slightly alkaline. The values of EC indicated that all samples of the soils are non-saline. The soil studies can be considered as good sources of essential nutrients and this information will help farmers to solve the problems related to soil nutrients and amount of which fertilizers to be used to increase the yield of Sunflower crop.
