Abstract: Integrated use of farm yard manure, seed inoculation with bio-fertilizers (Azotobacter spp and Azospirilium spp) and chemical fertilizers was carried out for evaluation of integrated nutrients through physical properties of soil under wheat (Triticum aestivum L.) crop [Cv.PBW-343] cultivation in Inseptisol, during cumulative study period of 2018-19 and 2019-20, at Research Farm, Department of Soil Science and Agricultural Chemistry, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj District of Uttar Pradesh. However, Significantly, with regard to physical soil parameters, cumulative mean value for percent water stable aggregates (54.22%), percent pore space (74.32%), and percent maximum water holding capacity (70.45%) was increased with reduced bulk density (1.11 Mg m^-3) opined in treatment (T₉) with 75% nitrogen + farm yard manure @ 5 t ha^-1 + Azotobactor spp + Azospirillum spp (3kg ha^-1) + Zn in comparison with chemical treatment (T₃) alone over control, (T₁). Thus, it could be concluded that integrated nutrients with respect to farm yard manure application along with bio-fertilizers and nitrogen, phosphrous and potassium, improves soil health condition and improves soil dynamics, soil biodiversity, developing the biological activities, increasing the environmental hygiene, soil conservation and supporting the ecology.
