Abstract

The integrated use of crop residues, biofertilizer and inorganic fertilizers in vertisol improved fertilizer use efficiency and nutrient turnover through augmentation of biological activity specially enzyme activity which is a step toward sustainable agricultural production. Highest soil microbial biomass C (340.25 μg Cg soil) and biomass N (30.15 μg N g soil) were recorded in Bradyrhizobium + 100% RDF i.e. 30 kg N + 75 kg P 2 O 5 ha treatment followed by incorporation of wheat straw @ 4 t ha + 100% RDF. Incorporation of wheat straw and sugarcane trash along with chemical fertilizer significantly increased SMBC and SMBN content over their alone application. There was significant influence of crop residues and biofertilizer on soil enzyme activity i.e. dehydrogenase activity over control. Incorporation of wheat straw @ 4 t ha + 100% RDF significantly increased soil dehydrogenase activity as compared to all other treatments. Bacterial and actinomycetes population were found maximum i.e. 29.6 CFU gx 10 and 25.0 CFU gx 10, respectively in seed treatment with Bradyrhizobium + 100% RDF, whereas, fungal population was found to increase (21.4 6 CFU gx 10) with the incorporation of wheat straw @ 4 t ha + 100% RDF followed by sugarcane trash with 100% RDF. Seed inoculation with Bradyrhizobium with 100% RDF recorded highest grain yield (24.59 ha) and was followed by wheat straw + 100% RDF. SMBC, SMBN, dehydrogenase activity and soil biota were significantly correlated with soybean yield.

8 of 15 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
