Abstract:
A study was undertaken to assess the chemical properties of soybean growing soils of Dharwad taluk in Dharwad district, Karnataka. Seventeen representative villages were chosen and total fifty one surface soil samples (0-15 cm) collected and analysed for chemical properties of soybean growing soils. Based on the average grain yields in 51 fields, the entire group was divided into below average and above average yield categories. Mean yield of selected fields was 14.67 q ha-1. Results revealed that the soil pH (1:2.5) varied from 6.81 to 8.67 with an average of 7.83 and 7.02 to 8.13 with an average of 7.68 in below and above average yield category respectively. Electrical conductivity (1:2.5) of soils varied from 0.13 to 0.45 with an average of 0.21 and 0.10 to 0.32 with an average of 0.20 in below and above average yield category respectively. The organic carbon content varied from 3.6 to 4.9 g kg-1 with an average of 4.27 g kg-1 and 4.6 to 7.5 g kg-1 with an average of 5.88 g kg-1 in below and above average yield category respectively. The data on free CaCO3 content varied from 52 to 152 g kg-1 with an average of 89.22 g kg-1 and 55 to 112 g kg-1 with an average of 74.53 g kg-1 in below and above average yield category respectively. Among the chemical properties, soil organic carbon was found to be positive and significantly correlated with yield (0.599**) in both below and above average yield categories.
