إن إنتاجية النبات هي خلاصة تضافر عدة عوامل و بمعايير محددة، مما يتطلب معرفة طبيعة العوامل
المؤثرة بهذه الصفة وطبيعة ارتباطها بها و تحديد هذه الطبيعة و اتجاهها و مقدار قيمة عاملها r و مدى
إسهام كل من العوامل المستقلة بالعامل التابع (الإنتاجية أو الغلة).
It is well understood that the productivity and thus the final yield of a crop
are the result of several interacted factors, which have different effects on yield.
This requires the determination of all factors affecting yield or other traits, the
relationships among these factors, the value of correlation coefficient and the
degree to which yield is affected by each of these factors.
