Influence of machine generated potting mixture in the growtl of black pepper (Piper nigrum L.) cuttings and nutmeg (Myristica fragrans Houtt.) seedlings in nursery

摘要

Black pepper, the 'king of spices' is one of the important export earners to the country. Though the area and production of the crop is more in India, our productivity is very less (400 kg ha1). For the production of quality planting materials, use ofgood potting mixture is required. Potting media composed of farmyard manure (FYM): sand: soil in 1:1:1 proportion was reported to give better rooting in pepper at Sri Lanka (Yufdy and Hayani,1991). Potting mixture consisting of soil, granite powder andFYM (2:1:1) was standardized for raising healthy cutting in black pepper nursery (Thankamani et al., 2008b).
