Criteria of Crop Evaluation from Environmental and Economic Literature:

The ecological evaluation of crop rotation was presented by WALEWSKI (1964). It was based on field-featuring resulting from pre-crop demands and the value of species sequencing. This method was enhanced by KRZYMUSKI (1983) including the element of productivity and work-consumption.

In another work, the same author used a theoretical model of quantified indicators in order to evaluate cereal in cereal crop rotation [KRZYMUSKI 1980]. This method allowed him to evaluate the value of a field; energy input of labour and machines, average cereal yield, production of goods and allowed the calculation of co-factors of production mechanization for three types of cereal crop rotation. The above method of a production-economic character initiated wide interest.

The economic evaluation of various crops was taken up by PYTKOWSKI (1985). The indicators such as the intensity of sowing structure, material consumption, production levels,
Objective and non-objective gross income and productivity were used. However, PRZYBYSZ (1976) developed wide studies upon the evaluation of crop rotation using statistical methods. NIEWIADOMSKI (1982) proposed ecological-economic level evaluations in which he considered thirteen indicators (ecological-8, economic-5). For example, he evaluated a few specified crop rotations such as cereal, beets, potatoes, com including monocultures.

The evaluation of the methods employed was undertaken by FILIPIAK (1988), FILIPIAK and KRZYMUSKI (1991) , KRZYMUSKI (1992) also wrote a monograph on the methods used in articles and Publications taken from source journals published on the occasion of the fifth seminar of Polish-Czech crop rotation (Olsztyn, 1991).

All possible methods of crop rotation evaluation were published in that book, such as the production, ecological and economic methods. He stated that in order to construct crop
Rotation, one has to set goals and production directions, determine regions, and manage
agricultural production areas and determine the sowing structure while bearing in mind that crop rotation is only the final phase connecting all production areas in a farm. The above subjects are part of the agricultural economy [ORLISKI 1986, VRKO 1992].

For many years various scientific authorities have demanded the use of the full plant production evaluations and particularly detailed economic evaluations including the calculation of labour and
