ABSTRACT
An investigation was carried out at Agricultural Research Station, Anand Agricultural University, Sansoli, Dist. Kheda, Gujarat during the year 2011-12. The treatment comprised of three biochars viz., maize stover (MS), cluster bean stover (CB) and Prosopis julifera wood (PJ) and one farmyard manure (FYM). The biochar and FYM both were applied @ 5 t and 10 t har1. The recommended dose of fertilizer (RDF) (80-40-0 kg ha-1 N-P-K) was applied in eight treatments and remaining eight treatments comprised of biochar and FYM. The full dose of P was applied in the form of single superphosphate @ 40 kg ha-1 whereas N supplied through urea @ 80 kg ha-1. The combined application of cluster bean (CB) and (PJ) biochars and FYM @ 10 t ha-1 along with RDF (RDF+MS10) increased dry matter yield, crude protein yield, chlorophyll content and plant height (at 30 and 60 DAS) as compared to maize stover biochar. The MS biochar @ 10 t ha-1 without RDF showed significantly the highest K concentration in maize plant. Though, P concentration was significantly highest in CB biochar @ 5 t ha-1 with RDF. But the reverse trend was observed in case of N concentration, which was significantly increased with the application of biochar @ 10 t ha-1 without RDF. Nutrient uptake like P was significantly increased with the application of RDF+MS10 while in case of uptake of N there was a significantly increased in RDF+MS5. Results indicates that various biochars studied with FYM are found most effective in obtaining significantly higher DMY and CPY and larger removal of nutrients from the soil and are also beneficial for built up nutrients in soil.
