Effect of soil application of neem cake amended with Trichoderma and Pseudomonas fluorescens on soil health and yield of tomato crop

Abstract

Chemical pesticide usage was increased and it may lead to the deposit of these pesticide residues on agricultural crops. Organic farming promotes eco-friendly agricultural practices without making use of synthetic inputs and majorly relies upon the use of organic wastes to raise crops. Neem cake which is a form of organic manure used in organic farming for the enhancement of crop yield. This experiment was designed to carry out the synergistic effect of neem cake amended with Trichoderma viridi and Pseudomonas fluorescens species. Neem cake along with 0.1% of microbial load did not affect the physical nature and chemical constituents of the cakes. We observed that the Trichoderma population was reached up to 1x10 7 cfu/gm and the Pseudomonas population was estimated as 1x10 8 cfu/ml.
