Abstract: Field studies were taken for three seasons (2016-17 to 2018-19) at the Main Sugarcane Research Station, Navsari Agricultural University, Navsari 396450, Gujarat to studies the production potential and economics of sugarcane based cropping system. Experimental results indicated that sugarcane-Ratoon (trash mulching with Trichoderma)-Maize produced significantly higher values of growth attributes (no. of tillers and plant height), yield contributing parameters (no. millable cane, cane and CCS yield) as compared to other cropping system in the study. Cane yield (118.66 t ha^-1) obtained under T₅ system (Sugarcane-Ratoon (trash mulching with Trichoderma)-Maize) was higher to the tune of 13.19%, 5.64%, 3.46, 8.39%, 19.53%, and 6.42% respectively than that of T₂ (Sugarcane-ratoon-moong bean), T₃ (Sugarcane-ratoon-(trash mulching without Trichoderma)-Maize), T₄ (Sugarcane-Ratoon-(trash removal without Trichoderma)-Maize), T₆ (Sugarcane-Ratoon-Maize (trash incorporation through rotavator and Trichoderma incorporation before sowing of Maize)), T₇ (Sugarcane-Ratoon-Maize (Zero tilled) without Trichoderma) and T₈ (Sugarcane-Ratoon-Maize (Zero tilled) with Trichoderma). Cane equivalent yield (CEY) and economic analysis revealed that the higher CEY (175.08 t ha^-1) was recorded highest with cropping system T₁ while net profit (₹ 436954 ha^-1) and benefit cost ratio (4.24) were recorded in T₅ cropping system as against other cropping system. Commercial cane sugar per cent was also recorded significantly highest in T₅ cropping system and exhibited almost similar trend as the yield of cane under different cropping systems while juice quality parameters did not alter significantly. Thus, sugarcane-Ratoon (trash mulching with Trichoderma)-Maize can be initiated as cropping system for reaping higher production potential and net return.
