Бонитетна оценка на климатичните условия при отглеждане на различни групи царевични хибриди

Абстракт

This paper presented sophisticated scales evaluation in cultivation of different groups of maize hybrids. Characteristics assessed аrе two - "active temperature amounts" аnd "atmospheric humidity balance for Пе period June -August".
Algorithms for specific assessments of individual characteristics represented by determination of restrictive ratings (with a solid assessment) and those described by regression equations. For the establishment of equations are used methods of our and foreign researchers (Georgiev, 2007; FAO, 1976). The final results аге represented by field rating. Thus field ratings of different parameters are more accurate and detailed.
