  1. NTJ, NTG, CTJ, CTG indicate no-till/japonica rice planting, no-till/glutinous rice planting, conventional tillage/japonica rice planting, conventional tillage/glutinous rice planting, respectively. Yield: 2-year average drying yield; the price of japonica rice is calculated in 0.3806 USD per kg, the price of glutinous rice is calculated in 0.4181 USD per kg; other costs include the cost of fertilizer, seeds, etc.; net income = gross income − production costs
