Abstract: The study was carried out to understand the influence of pressmud enriched with isolated microflora of pressmud on laboratory scale pot experiments with chickpea, Cicer arietinum and spinach, Spinacia oleracea and recorded physico-chemical characters of soil and the phyto-chemical characters of chickpea and spinach. Initially, physico-chemical characters of pressmud (PM), composted pressmud (CPM) and enriched composted pressmud (ECPM) were studied for pH, moisture content, water holding capacity, total organic carbon, organic matter, nitrogen, potassium and phosphorous. Experiments were conducted with combinations of soil without pressmud (T₀), soil with CPM (T₁) and soil with ECPM (T₂). T₂ shows maximum, i.e., 2.01%, 1.03% and 0.29% of NPK. T₂ observed promising growth for chlorophyll, ascorbic acid, polyphenols, proline, protein, indole acetic acid, total amino acids and flavonoids. It also resulted in maximum chlorophyll content 12.43 mg/100 gms, and 112.94 mg/100 gms, ascorbic acid 1,235 mg/100 gms and 1,332 mg/100 gms, flavonoids is 0.38 mg/100 gms and 0.35 mg/100 gms and amino acids 1.80 mg/100 gms and 0.58 mg/100 gms for chickpea and spinach respectively. The experiments suggest that the combination of soil with ECPM gives good results and can be practiced in the fields.
