They are significantly hardier and of higher yield than criollo. Pathogens can lead to high reductions in crop yield. Process variation is one among many reasons for low yield. A typical reaction yield exceeds 95%. Given is equal to , these formulas yield , , , , and so on. This time the yield of exceeded expectations. This approach usually does not yield firm results. However, these efforts did not yield any results. Each component will yield a corresponding eigenvalue. These sources use a variety of sampling techniques that yield different measures. It does not yield an absolute directly. The variabilities of yield and yield components are high. Regardless, all three analyses yield the same interpretation. The average venom yield for a male is . This mitigates the effect of variations in soil composition on the yield.
