ENRICHMENT OF PROTEIN CONTENT OF PODS AND FRUITS OF VEGETABLE PLANTS EXPOSED TO DIFFERENT PERCENTAGES OF VERMICOMPOSTP.K. RAMASAMY AND S. UMAVATHI
The decline in the nutrient level of agricultural land is an important drawback due to continuous cultivation. In order to increase the soil fertility, inorganic fertilizers are being widely utilized in our cultivable lands. Even though they promote the growth of crops, their toxic effect is the negative impact by means of their over utilization. To overcome all these unwanted factors the application of organic manure especially vermicompost is recommended. Vermicompost is a rich source of macronutrients, micronutrients, vitamins, plant enzymes and plant growth hormones. So, the present investigation was performed to study the influence of vermicompost on protein content in the pods and fruits of Ladys finger (Hibiscus esculentus L.), Indian butter bean (Dolichos lab lab L.) and Tomato (Solanum lycopersicum L.). Different percentages of vermicompost (25%, 50%, 75% and 100%) derived from the earthworm, Eudrilus eugeniae was made with red soil. The Ladys finger (Hibiscus esculentus L.), Indian butter bean (Dolichos lab lab L.) and Tomato (Solanum lycopersicum L.) plants were cultivated in these vermicompost-red soil mixtures for 90 days period of exposure. At the end of 90 days the pods of Ladys finer and Indian butter bean and fruits of the tomato plant were collected and tested for the level of the protein content. In the present study, high level of protein content was noticed in the pods of the Ladys finger and fruits of the Tomato plants grown in 50% vermicompost concentration but at the same time the high level of protein was noticed in pods of Indian butter bean plant cultivated in 75% vermicompost concentration. However, the low level of protein was noticed in the pods of Ladys finger and Indian butter bean and in the fruits of the Tomato from control plants of both plants.
