Abstract
A recognition of the crop-environment relationships is essential to provide crops with the optimum growing conditions. The response of the crops to air temperature and solar radiation differs quite considerably even for the same variety. There are always an optimum, a supraoptimal and a suboptimal growing condition for each crop; at optimum the crop growth is highest and less than this at the other conditions. Therefore the "comfort" limits for the crops vary and there may be different limits for growth and yield for the same crop.

Abstract
Bitkilerin çevre ile olan ilişkilerinin bilinmesi, onları büyümesi için en uygun bir ortamın oluşturulmasına yardımcı olmaktadır. Bitkilerin sıcaklığa ve güneş ışınımına tepkileri farklı derecelerde olmaktadır. Bitkiler belli bir sıcaklık değeri altında (örneğin Patlıcan için bu değer 10° C) güneş ışınım şiddeti ve diğer etmenler sabit kabul edildiğinde büyümemektedir. Sıcaklık ve güneş ışınımı şiddeti "optimum" denilen belli bir değerde olduğunda büyüme (diğer bir deyişle bitkinin "iş verimi") en yüksek düzeyde olmaktadır. "Supraoptimal" ve "Suboptimal" denilen en uygun değerlerin üzerindeki ve altındaki değerlerde bitki büyümesi yavaşlamaktadır. Buna göre bitkiler için "konfor" sınırları bitki türüne göre değişmekte ve büyüme ve verim açısmdanda çok farklı olabilmektedir.
