Abstract
Aim: To evaluate the inhibition effects of aqueous extracts of coir pith and composting coir pith on Rice (Oryza sativa), Black gram (Vigna mungo), and Green gram (Vigna radiata) by response index method.
Methodology: The coir pith and composted coir pith soaked the ratio of 1:10 for 24 hrs, filtered through Whatman No.1 filter paper. The inhibition effect tested for germination and seedling growth of Rice, Black gram, and Green gram was sown in poly pots. The Carbon: Nitrogen ratio and the total organic carbon analyzed by Dry combustion method, Kjeldahl method, and GCMS/MS analysis.
Results: The phytotoxic substances are present in coir pith, which can be exterminated by composting the coir pith for better growth and development of seedlings.
Interpretation: The negative response index (RI), high C: N ratio and chemical compounds like Tocopherol, Fucoxanthin, Tetramethylheptadeca, Dichloroacetamide, Tetrazole, Hydroxyethyl palmitate, Neocurdione, and Uridine derivations present in raw coir may have the phytotoxic effect of yellowing symptoms in young plants compared to composted coir pith. This is exterminated by composting the coir pith for better growth and development of seedlings as well as used for various agricultural and horticultural nurseries
