dc.description.abstractAn experiment was carried out in Banavasi area of Uttara Kannada district to study the nutrient management practices adopted by ginger farmers and its effect on soil properties and ginger yield. Based on the nutrients application the farmers were classified into three groups- G1: Local Farmers-1 (High OM and High Fertilizers), G2: Local Farmers-2 (Low OM and Moderately High Fertilizers) and G3: Migrated Farmers (Very Low OM and Very High Fertilizers). The soil samples were collected after harvest of ginger crop at surface (0-15 cm) and subsurface (15-30 cm) soil. The soil pH and EC did not show any significant difference among different category of ginger farmers. The soil organic carbon and carbon stock varied significantly in the order of G1 > G2 > G3 respectively and higher the soil organic carbon (1.33 ± 0.08 %) and soil carbon stock (23.17 ± 1.60 t ha-1 ) were observed in Local Farmers-1 group. The major and secondary nutrients status varied significantly among three groups. However, higher available nitrogen (378.48 ± 13.40 kg ha-1 ), phosphorous (32.34 ± 3.36 kg ha-1 ), potassium content (365.44 ± 30.55 kg ha-1 ), calcium (5.72 ± 0.54 meq 100 g-1 ), magnesium (3.36 ± 0.23 meq 100 g-1 ) and sulphur (26.47 ± 3.34 kg ha-1 ) was noticed in Migrated Farmers group. Similarly, micronutrient (Fe, Mn, Zn and Cu) content was found higher in fields of migrated farmers soils compared to other groups. Local farmers-1 who had applied more organic manures recorded higher dehydrogenase (15.21 ± 2.92 µg TPF g-1 of soil day-1 ) and acid phosphatase activity (22.38 ± 2.23 µg PNP g-1 of soil hr-1 ). While, urease activity (132.81 ± 8.59 µg NH4 + released g-1 soil hr-1 ) was significantly higher in Migrated Farmers group. The higher rhizome yield (31.00±2.94 t ha-1 ) was observed in Migrated Farmers group compared to Local Farmers-1 (22.35±1.50 t ha-1 ) and Local Farmers-2 (17.91±1.72 t ha-1 ). In terms of nutrients expenditure, the local farmers-1 has spent highest money and fallowed by Local Farmers-2 and migrated farmers. Injudicious nutrients application was found in migrated farmers thus, there is need to educate them on balanced and optimization of nutrients supplementation on soil sustainability.
