What is the effect of these factors on the stored grains?

Four factors which greatly affect grain storability are (1) grain moisture content; (2) grain temperature; (3) initial condition of the grain; and (4) insects and molds. These factors are all interrelated.

What do biotic factors affect?

A biotic factor is a living organism that affects another organism in its ecosystem. Examples include plants and animals that the organism consumes as food, and animals that consume the organism. The scope of abiotic and biotic factors spans across the entire biosphere, or global sum of all ecosystems.

What abiotic factors affect grain storage?

How do you store grains?

Heat, air and moisture are the enemies of whole grains. All whole grains should be stored in airtight containers with tight-fitting lids or closures. The type of container is a matter of preference. Glass, plastic, and aluminum canisters or zip-top plastic bags can all be successfully used, as long as they are airtight.

Herbivores with significant deleterious effects on crop growth and yield are called pest. Damage caused by these biotic factors are varied such as death of the entire plant or organs, reduced root, stem, leaf or inflorescence mass, total defoliation, bores and holes on plant parts, and other marks of feeding.

What are the biotic factors in crop production?

Biotic constraints to agricultural production are broadly identified as weeds (plants), pests (animals), and diseases (fungi and bacteria), and their related biological interactions (namely, competition, herbivory, and predation and parasitism), which cause reductions in physical yields or yield quality.

How does biotic factors affect the environment?

The biotic factors in an ecosystem are the living organisms, such as animals. … These living organisms affect each other and influence the health of the ecosystem. A healthy ecosystem has a balance of biotic examples; a large increase or decrease in population of one species can impact many others.

How does biotic factors affect abiotic factors?

A biotic factor is a living thing that has an impact on another population of living things or on the environment.
