Abstract:

In India, about 435.98 million tons of agro-residues are produced every year, out of which 313.62 million tons are surplus. These residues are either partially utilized or un-utilized due to various constraints[7]. Biochar and biochar-compost mixtures from different alternative organic sources have been proposed as an option for improving soil fertility, restoring degraded land and mitigating the emissions of greenhouse gasses associated with carbon sequestration and climate change. A pot culture experiment was carried out with seven treatments implying sugarcane trash biochar @ 2 tonnes and 4 tonnes /ha in combination with sugarcane trash compost, farm yard manure, press mud, sunhemp and 100% recommended dose of NPK. Results showed that the total N content of sugarcane was increased in cane (0.32%), trash (0.732%) and root (0.458%). The total P content of cane was also improved to 0.120%in cane, trash to 0.271% and root to 0.094%. The organic carbon and available nitrogen content of soil was enhanced to 0.298% and 211.53 (kg/ha) respectively in the treatment receiving 100% recommended NPK along with sunhemp@10 t/ha and biochar of 2t/ha. The same treatment resulted in a better improvement of germination of 91.33%, tillering population of 173378/ha, millable cane population of 127000.47/ ha, Leaf area of 464.22 cm2, plant height of 343.75 cm, cane length of 216.67 cm, cane girth of 2.46 cm, root length of 41.17 cm, internodes length of 10.42 cm, number of nodes of 24.33 cm, single cane weight of 1707.75 g and cane yield of 128.43t/ha. These findings lead us to suggest that further investigations are needed to assess the effect of biochar on plant and ratoon cane yields.
