Field experiments were conducted during 2006-07 to 2008-09 at Sugarcane Research Institute, Pusa, Bihar to study the effect of Trichoderma inoculated trash, nitrogen level and biofertilizer on yield, nutrient uptake, juice quality of sugarcane ( Saccharum officinarum L.) and soil nutrient availability in calciorthents. Trash was inoculated with Trichoderma viride @ 500 g/t, one week before planting and applied @ 10 t/ha alone or in conjunction with different levels of N (75,112.5 and 150 kg/ha). Application of trash alone increased the mean cane yield by 1.8% over control (45.4 t/ha) and with N levels 75,112.5 and 150 kg/ha, increase in cane yield were 5.5, 3.3 and 0.8%, respectively over N applied alone. Trash applied with 75,112.5 and 150 kg N/ha improved the organic carbon by 8.2, 11.3 and 13.6%, respectively over N applied alone while, available N by 7.0, 10.3 and 8.6%, P by 2.9, 7.6 and 4.6% and K by 7.4, 4.6 and 5.3%, respectively. Addition of trash and biofertilizer alongwith recommended dose of nitrogen (150 kg/ha) gave the highest net income (Rs. 22,832/ha) and B:C ratio (1.43). Hence, addition of Tricho- derma inoculated trash @10 t/ha alongwith 150 kg N/ha and Azotobacter @ 4 kg/ha were found beneficial for sus- taining soil health, enhancing sugarcane productivity and getting higher net returns.References
