In order to avoid monoculture, it has been proposed a crop rotation system with five crops (200<!--> <!-->ha for each crop), as follows: rape – wheat – corn – sunflower – peas. The effects of avoiding monoculture have immediately appeared, especially in diminishing the diseases, pests and weeds percentage with about 38.4%. An essential part of the whole algorithm is represented by the crop nutrition, mainly by the nitrogen one for wheat, since it directly affects the yields quantity and quality. Thereby, a part of the nitrogen currently applied from bag (synthesis nitrogen) has been replaced with biological nitrogen, obtained from the input provided by using peas as preceding plant (130<!--> <!-->kg N/ha, which means an average of 26<!--> <!-->kg N/ha/year) and by the association made by wheat with the <em>Azospirillum brasilense</em> bacteria (90<!--> <!-->kg N/ha, namely an average of 18<!--> <!-->kg N/ha/year).

Doing a ratio between the biological and the synthesis nitrogen, it will appear that 46.4% of the nitrogen required by the plants for the whole crop rotation system can be supplied at no cost and without causing damages to the environment.

Persimmon were packed using two types of packaging materials: plain cardboard boxes and cardboard boxes with modified atmosphere packaging (MAP) using 40-μm thick low density polyethylene (LDPE) film as an inner packaging material.

The softening of fruit was judged directly by touch and fruits that had even slightly softened were regarded as softened fruits.
