Abstract

Aim- Numerous plants and animal origin resources have been reported to have antimicrobial activity and can enhance plant growth also. The present research work was undertaken to investigate the antimicrobial activity of cow urine against gram negative bacteria Aeromonas hydrophila and also to determine efficiency of cow urine as a plant growth enhancer. Methods- The antimicrobial activity of various concentrations (0, 100, 300, 500, 700 & 1000μl) of fresh cow urine and photo activated urine was determined by spectrophotometric method. The pot culture method was also performed to find out the efficacy of various concentrations of cow urine (0%, 1%, 2%, 3%, 4% & 5%), on growth of gourd and brinjal plants. Each pot containing seeds was watered two times a day with different concentrations of cow urine and the control pots were watered only with tap water. After 25 days’ various parameters were determined such as plant height, shoot length, root length, number of leaves and branches to detect the plant progress. Result & Discussion- The results indicated that fresh cow urine with highest concentration has better antimicrobial activity as compared to photo activated urine with highest concentration. The effect of cow urine on plant growth was also evaluated with Lagenaria siceraria (gourd) and Solanum melongena (brinjal) plants, it was seen that plant height, number of leaves and number of branches of gourd and brinjal was increased by increasing the concentration of cow urine and length of time. Conclusion-Thus we concluded that the cow urine possesses antimicrobial activity and also have favorable impact on the production of gourd and brinjal plants.
