Abstract
A study was conducted to assess the effect of in-situ incorporation of paddy straw along with microbial inoculants on the yield of wheat crops. Locally available, waste, paddy straw (shredded to 3–5 cm) was incorporated with and without a mesophilic cellulolytic fungal inoculum (Trichoderma viride) in alluvial sandy loam soil at 11·2 tonnes ha−1 15 days prior to sowing. Seed bacterization with a free-living nitrogen-fixer (Azotobacter chroococcum) and phosphate solubilizer (Pseudomonas striata) was done in the respective treatments. Application of a single microbial inoculant in combination with two fertilizers, urea and rock phosphate at 60 kg N ha−1 and 60 kg P2O5 ha−1, respectively, produced a significant effect on the yield of wheat grown in straw-amended soil. Combined inoculation with all the three organisms had a repressive effect on the yield of wheat.
