Harvest Index vs Harvest Maturity Index: What’s the Difference and Why It Matters

The harvest index and harvest maturity index maximize yield and quality but involve different purposes, measurement methods, stakeholders, timing, and target crops. The harvest index is used during the research and cultivar development stage to measure plant function efficiency and estimates the carbon allotted to make harvestable products. The harvest maturity index estimates the best… Continue reading…

What Is The Best Apple Harvest Maturity Index?

Apple harvest maturity indices are mainly based on physical and chemical attributes. The most reliable method is the starch index. The harvest maturity index values differ based on cultivars and the storage time. Each fruit is distinctive, and the methods used to fix harvest time must be customized for each cultivar. Determining the optimum harvest… Continue reading…
