Effects of Unburned Lime on Soil pH and Base Cations in Acidic Soil

Table 4

Effects of limes on potato yield (𝑃<0.001 and LSD 3.28) and RAE (%).

Lime rates	Yield (kg ha^−1)				RAE (%)
	Agricultural lime	Karongi lime	Musanze lime	Rusizi lime	Karongi lime	Musanze lime	Rusizi lime
Control (0 t ha^−1)	14.32	14.32	14.32	14.32	—	—	—
1.4 t ha^−1 (1/2 rate)	18.88	17.88	19.63	18.06	80.43	113.04	82.61
2.8 t ha^−1 (full rate)	22.47	19.62	22.15	21.08	65.85	95.12	82.93
4.2 t ha^−1 (1.5 rate)	24.82	19.23	24.9	21.85	47.62	100	72.38

RAE = 100: equal efficiency of local lime and agricultural lime; RAE > 100: more efficiency than agricultural lime; RAE < 100: less efficiency than agricultural lime.
