ECONOMIC EVALUATION OF DIFFERENCES IN PLANTING DENSITIES |
| Author: | C.O.N. de Vroomen |
| Abstract:
A method is reported for economic evaluation of the effects of various planting densities on cash returns and the costs influenced by changing planting density. The formula derived from a study in a tulip cultivar can also be used for other tulip varieties and bulb species. The calculation made for a constant acreage corroborated the existing opinion about the optimal planting density for the tulip cultivar ("Preludium") but because the relationship between planting density, harvested bulb weight per plant, and grading is specific for each variety, the conclusions do not necessarily hold for other varieties. | |
