Abstract
An experiment was conducted at College of Agriculture, Vellayani of Kerala Agricultural University to investigate the efficacy of biochar from tender coconut husk for enhanced crop production. Biochar was produced, characterized and tested in the field at different levels of application viz. 10 and 20 and 30 t ha-1 using yard long bean variety Vellayani Jyothika as the test crop during January 2013 to April 2013. Along with biochar, other commonly used organic manures viz. Farm yard manure and vermicompost; biofertilizers namely Plant Growth Promoting Rhizobacteria (PGPR) and Arbuscular Mycorrhizal Fungi (AMF) were also tested in the field. The experiments were laid out in Randomized Block Design with three replications. The treatments were 1. Package of Practices recommendation (POP), 2. Biochar @ 10 t ha-1 + NPK as per POP, 3. Biochar @ 20 t ha-1 + NPK as per POP, 4. Biochar @ 30 t ha-1 + NPK as per POP, 5. Biochar @ 20 t ha-1 + 75 % NPK as per POP, 6. Biochar @ 10 t ha-1 + FYM @ 10 t ha-1 + 75 % NPK as per POP, 7. Biochar @ 10 t ha-1 + vermicompost @ 5 tha-1 + 75% NPK as per POP, 8. Biochar @ 20 t ha-1 + 2 % PGPR + NPK as per POP 9. Biochar @ 20 t ha-1 + AMF @ 200 g m-2 + NPK as per POP. Biochar application @ 20 t ha-1 along with 2 % PGPR and NPK as per POP resulted in better total dry matter production (TDM), pod protein, Harvest Index (HI) and finally B: C ratio and pod yield.
