Resumo: 	The experiment aimed to study the effects of crop rotation in sugarcane field during the last ratoon harvest and planting a new sugarcane crop, on soil improvement, increasing sugar yield and economic return in northeast Thailand. The effect of Jack bean (Canavalia ensiformis), sunn hemp (Crotalaria juncea), upland rice (Oryza saliva L.) fallowed as the rotation system. The experiment was a Randomize Complete Block Design with three replications and 7 treatments. They included T1) farmer’s method (fallow followed by sugarcane receiving chemical fertilizer control (15-15-15 at 50 kg/rai), T2) fallow followed by sugarcane receiving chemical fertilizer (16-16-16 at 25 kg/rai+22-8-10 at 25 kg/rai and compost fertilizer at 2 tons/rai), T3) sunn hemp planting as green manure followed by sugarcane, T4) sunn hemp planting for seed harvesting and then were ploughed and followed by sugarcane, T5) jack bean planting as green manure and followed by sugarcane, T6) jack bean planting for seed harvesting and then was ploughed after seed harvested and followed by sugarcane, and T7) upland rice planting and ploughed after seed harvested followed by sugarcane. Sugarcane in treatment 3-7 was applied fertilizer grade 15-15-15 at the rate of 50 kg/rai. This experiment conducted in a farmer field upland at Phulek village, Ban Phai district, Khon Kean province; soil group 41 (Ban phai soil series). The results showed that soil chemical properties were changed in the green manure treatments. The green manure treatments and the upland rice straw ploughed under treatment gave higher economic return compared to these of non-green manure treatments. Sugarcane growing in T7 gave the highest yield at 18.84 tons/rai while T5 gave 18.74 tons/rai. T7 treatment gave the benefit return of 2-year at 12,050.72 bath/rai while T5 gave 8,666.44 bath/rai. The result from the two-year experiment suggested that sugarcane farmers in northest Thailand should grow jack bean or upland rice as crop rotation in the sugarcane field in order to improve soil fertility and also increase the sugar cane yield. This will help sustain the soil for sugarcane production in the region
