In order to be able to prepare accurate calculations we had to determine the area and number of plants both in the case when the seeds were sown in the field and when they were in seedling transplants. The time requirements of the treated areas and also material used associated with the different modes of propagation varied. There are significant differences between the field and forcing technologies as for construction-related costs. The expense and cost calculations were based on the operation. The calculation includes the operating natural inputs (labour, material used), and are expressed in monetary value: the costs (wages, cost of materials). Costing does not count with the common charge, since the production process has not been completed yet. In this calculation the cost of labour is recognized. We calculated the area which can give enough profit to support the farmer and his family.
