1. Expressed as man-hours per 1,000 culms. 



2. Subcrews of one man digging, one man planting. Figures are for thoroughly 

 moist planting surface only; dry surface sand increases planting time. 



3. Crew seated on transplanter. 



4. Crew walking behind transplanter; method limited to level site with moist sand. 



5. Total figure available only. Includes processing (trimming leaves from culm).
