Abstract:
The present investigation in relation to “Dynamics of phosphorus under different soils of wheat growing area of Sindkhed Raja Tehsil in Buldhana district” was under taken during 2020-2021. 50 farmers were selected from 12 different villages in Sindkhed Raja Tehsil. Surface soil (0-15 cm) samples were collected for analysis from sites. When analysed before sowing, the soil of Sindkhed Raja Tehsil were Aluminium bound phosphorus of before sowing of wheat crop is ranged from 2.91 ppm to 4.16 ppm and after harvest of wheat aluminium bound phosphorus ranged varied from 3 ppm to 4.22 ppm. Saloid bound phosphorus of before sowing of wheat crop is ranged from 28.35 ppm to 36.81 ppm and after harvest ranged varied from 28.74 ppm to 37.32 ppm. Iron bound phosphorus before sowing ranged from 18.83 ppm to 24.45 ppm and after harvest ranged varied from 19.09 ppm to 24.79 ppm. Reductant phosphorus before sowing of wheat crop is ranged from 26.90 ppm to 34.92 ppm and after harvest ranged varied from 27.27 ppm to 35.41 ppm. Occluded phosphorus before sowing of wheat crop ranged from 151.44 ppm to 209.73 ppm and after harvest ranged varied from 153.53 ppm to 212.63 ppm. Calcium bound phosphorus before sowing of wheat crop is ranged from 12.04 ppm to 19.49 ppm and after harvest varied from 12.21 ppm to 19.76 ppm. Organic phosphorus before sowing of wheat crop is ranged from 187.95 ppm to 263.66 ppm and after harvest it varied from 194.99 ppm to 248.17 ppm. Total phosphorus before sowing of wheat crop ranged from 444.10 ppm to 565.35 ppm and after harvest it varied from 452.50 ppm to 579.52 ppm. It was observed that grain yield increases as fraction increases, hence; all the forms of phosphorus were highly significant and positively correlated with yield of wheat.
