In climate engineering, the residue-to-product ratio (RPR) is used to calculate how much unused crop residue might be left after harvesting a particular crop. Also called the residue yield or straw/grain ratio, the equation takes the mass of residue divided by the mass of crop produced, and the result is dimensionless.
The most significant factor is the ratio of the surface area of the fruit or vegetable to its volume. The greater the ratio the more rapid will be the loss of water. The rate of loss is related to the difference between the water vapour pressure inside the produce and in the air. Produce must therefore be kept in a moist atmosphere. [8]
This is because an index is based on a geographical area within which farmers may have different experiences with, e.g., rainfall. As a consequence some farmers may achieve a good crop when most others in the area experience a crop failure. However, under an index-based system all farmers receive payouts.
In integrated pest management, the economic threshold is the density of a pest at which a control treatment will provide an economic return. [1]An economic Injuryis the insect's population level or extent of crop damage at which the value of the crop destroyed exceeds the cost of controlling the pest. [2]

Agriculture in Singapore is a small industry, composing about 0.5% of the total GDP, within the city-state of Singapore. Singapore's reliance on imports for about 90% of its food underscores the paramount importance of food security. To address this, Singapore has set a goal to produce 30% of its nutritional needs locally by 2030. [1]
This article focuses on the damage incurred to grain between the field and its end use. Therefore, the first cause of grain damage is harvesting itself. A large cause of grain damage is mechanical damage incurred during the threshing process in a combine. This process of stripping the grain from the plant can often cause cracks and other damage.
The combine grain yield monitor is a device coupled with other sensors to calculate and record the crop yield or grain yield as a modern-day combine harvester operates. Yield monitors are a part of the precision agriculture products available to producers today that provide producers with the tools to reduce costs, increase yields, and increase efficiency.
