Figure 78. Total labour use per acre (days/year)<br />

Figure 79. Labour use per acre for food and tree crops (days/year)<br />

intensity per cultivated area which is substantially<br />

higher in the North than in the East (Figure 79).<br />

This would imply that the most efficient use of<br />

labour takes place in Kono, followed by Kenema,<br />

Tonkolili and Bombali qualify as the least<br />

efficient.<br />

When distinguishing between food and<br />

tree crop production, the results show that food<br />

cropping is more labour intensive than the tree<br />

cropping, about 2-3 times on an acre base (Figure<br />

79). Tree production seems to be the less labour<br />

intensive in Kono district, while in Tonkolili food<br />

cropping entails the highest labour intensity.<br />

In the Figures 80 to 84, output obtained and<br />

surface used per working unit are calculated in<br />

physical terms for different crops, particularly for<br />

Upland rice, IVS rice, Boli rice, coffee and cocoa<br />

(See Appendix IV for the same results at district<br />

level).<br />

In the case of upland rice, Figure 80<br />

illustrates the distance existing between the best<br />

practice farms (through which an empirical best<br />

practice frontier is drawn) to all remaining farms<br />

in the sample. This allows to compare how farm<br />

household stand in relation to the best performing<br />

smallholders in upland rice production per
