Labour productivity and structure of labour time during spraying treatment in greenhouse-grown crops.

摘要

The aim of the studies was to determine the labour productivity and structure of labour time of plant protection treatments with the use of spraying technique in greenhouse-grown tomato crops using 2 000 dm3/ha of working liquid and the sprayer "Sleza". In the period 18.02.2003-08.09.2006 (with respect to duration of cultivation 27-251 days) 25 observations of labour day were made. Average labour productivity was 0.75 ha/h. Taking into consideration the labour time structure was revealed that auxiliary time predominated.
