EFFECT OF BIOCOMPOSTED VEGETABLE AND GROUNDNUT SHELL WASTE ON THE GROWTH IMPACT OF PIGEON PEA (CAJANUS CAJAN (L.) MILL SP.)

Department of Botany, Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore, Tamil Nadu, conducted a pot culture experiment for analyzing the effect of bio-composted groundnut shell and vegetable waste on the growth impact of Pigeon pea (Cajanus cajan (L.) Mill sp. Organic wastes and by-products are renewable forms of resources generated all over the world. The present work explores the potential application of eco-friendly compost from groundnut shell and vegetable wastes. The study mainly deals with the physicochemical properties of raw and composted vegetables and groundnut shell Waste, pH and Electric conductivity, Lignin, Total Nitrogen (N), Total Phosphorous (P), Total Potassium (K), and C: N ratio. Composting was carried out with the help of Trichoderma asperelloides, Pleurotus florida, and Eudrilus eugeniae. The experiments consist of four treatments viz., C control, T1- compost 1 (Vermi-composted groundnut shell and vegetable waste (25g)) T2- compost 2 (Vermi-composted groundnut shell and vegetable waste (50g), T3-compost 3 (Vermi-composted groundnut shell and vegetable waste (75g). Chlorophyll, protein, and carbohydrate content were analyzed in the test crop (Cajanus cajan (L.) Millsp.) During 15, 35, 55, and 75 days. The treatment T3- compost 3 consisting of vermicomposted groundnut shell and vegetable waste (75 g) shows significantly increased chlorophyll, protein, and carbohydrate content as compared to the control and T1, T2 treatments. The reuse of groundnut shell and vegetable waste compost can be used as an appropriate method of environment management. Hence, from the present investigation, it was clear that bio-composted groundnut shell and vegetable waste enhanced the biochemical parameters in the leaves of pigeon pea.
