An experiment was conducted at College of Agriculture, Vellayani to study the effect of mineral enriched composts on soil remineralization, yield and nutrient uptake of yardlong bean during 2014-2015. Five types of composts enriched with different additives mineral enriched compost (rock dust 25%), bioenriched compost (composting inoculum 5g/kg), biomineral enriched compost (Rock dust 25%+ composting inoculum 5g/kg), mineral enriched vermicompost (rock dust 25%) and an ordinary compost were prepared and applied to crop as per treatment on 50% and 75% N basis with and without biofertilizer (PGPR Mix -I). Among all the treatments 50% N as mineral enriched vermicompost in conjunction with biofertilizer has performed best in yield , nutrient uptake by the crop and nutrient content in soil. Hence from the study it can be concluded that 50% of mineral enriched vermicompost in conjunction with biofertilizer recorded the highest yield and also played a vital role in soil remineralization.
