, there is little information on the variability in phytosterol content in almond germplasm, because the literature only provides results from analyses of commercial almond samples. For example, the analysis of a single sample of almond kernels from a

Harvester-mounted yield sensors have prompted many investigations into the amount of spatial variability present in grain, cotton, viticulture, and some mechanically harvested horticultural crops (usually vegetable crops). Investigations into the
