The field investigation in relation to "Effect of different organic inputs on soil biological properties, yield and quality of crops under certified organic farms in Nagpur district of Maharashtra” was carried out during kharif- rabi season of 2017 – 18, to assess the biological properties of soil, quality and yield different crops as influenced by various organic resources. Soil samples of 0-10 cm depth were collected randomly after the harvest of crops from six locations of Nagpur district were selected for recording various observations and collected plant samples for quality parameters. Yield of crops was noted from farmer’s field of above locations. The maximum microbial count was recorded in organic field over the inorganic field. The count of bacteria, fungi and actinomycetes were varied from 16.25 to 22.50 X 107
, 10.75 to16.25 X 105
and 7.25 to 13.5 X 105
respectively..In all the locations the yield of Nagpur Mandarin found higher as compared to national average productivity of Nagpur mandarin (10.4 t ha-1
). The yield of sweet orange recorded 14.0 t ha -1
with the application of Ghanjivamrut @ 500 kg ha-1
. Grain yield of wheat was obtained between 1.9 kg ha-1
.When the field applied FYM for 9 years, maximum grain yield of pigeonpea was obtained with fertilizers alone as compared to application of organic source. The quality of crops was improved with application of organic inputs over the fertilizers application. The higher ascorbic acid concentration (49.15 mg 100 ml-1
) of mandarin was recorded when ghanjivamrut @ 500 kg ha-1
was applied, Similarly in tomato the maximum ascorbic acid contain (23.37 mg 100 ml-1
) was recorded in organically produce tomato. The protein percent of rice was found maximum in organic field. From the study it can be concluded that, the application of organic inputs improve the chemical, biological properties and fertility status of soil. In case of yield due to organic inputs littilbit decreased. Therefore organic and inorganic fertilizers in balanced form are efficiently sustain and enhance the fertility status of soil and maintained the yield and nutritional quality of various crops.
