How abiotic factors affect storage of grains?

In addition to living organisms, there are also abiotic substances that affect grains. The crops are affected by factors such as air quality, humidity, and temperature. These factors may have a severe impact on grain storage if the quantity and quality are unbalanced.

How do abiotic factors causes loss to stored grains?

The factors responsible for losses of grains during storage are: (i) Abiotic factors like moisture (present in food grains), humidity (of air) and temperature. (ii) Biotic factors like insects, rodents, birds, mites, bacteria and fungi.

How do biotic and abiotic factors affect storage of food grains?

The factors responsible for loss of grains during storage are: (i) Abiotic factors like moisture (present in foodgrains), humidity (of air) and temperature. (ii) Biotic factors like insects, rodents, birds, mites and bacteria.

What factors affect storage of grain?

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.

How biotic and abiotic factors can affect agricultural produce during storage?

Biotic factors like insects, rodents, pests, and many more spread the disease and reduce crop production. … Abiotic factors like humidity, temperature, moisture, wind, rain, flood and many more destroy the crop raise. Abiotic factors like hot, cold, drought, salinity, etc. affect crop production.

What are biotic and abiotic factors affecting storage?

Abiotic factors: The abiotic factors means the non-living things like temperature, moisture, soil, water etc. … Inappropriate moisture and temperature in the place of storage also affect the stored grains. Biotic factors are all of the living organisms within an ecosystem. …

What is the purpose of storage of grains How are grains stored?

For small farmers the main purpose in storing grains is to ensure household food supplies. Farm storage also provides a form of saving, to cover future cash need through sale, or for barter exchange or gift-giving.

How abiotic factors spoil food grains?

1. Temperature: If food is stored at lower temperature, then enzymes, insects and the other micro-organisms, which spoil the food, become less active. The damage to the stored food is decreased. … Humidity: Growth of moulds and fungi in food grains takes place due to humidity of air.

What do you mean by storage and what are the factors affecting the storage?

Factors that affect food storage: Temperature: The temperature at which food is stored is very critical to shelf life. … Moisture: It is recommended to remove moisture when storing foods. … Oxygen: Foods store best when oxygen free. … Light: Light, a form of energy that can degrade the food value of foods.

What are the factors that can cause loss of storage crops?

The storage losses are affected by several factors, which can be classified into two main categories: biotic factors (insect, pest, rodents, fungi) and abiotic factors (temperature, humidity, rain) [32]. Moisture content and temperature are the most crucial factors affecting the storage life.

What are two important factor affecting the quality of storage?

High temperature and high moisture are the most significant factors affecting grain quality in storage.

How does storage affects the physical properties of cereals and pulses?

During storage the barley moisture content is in equilibrium with the moisture content of the air. Therefore, grains may be further dried or they can absorb water from the surrounding air during storage. The storage life of stored grains is increased by cooling.

How temperature and moisture affect the storage of food grains?

Food is advised to store in an environment which has less temperature and moisture. High humidity(High temperature and high amount of moisture in air) led to growth of microorganisms which led to rotting of food grains. So temperature and moisture are important factor which affects the life of food materials.

Why storage of food grains are essential?

It is important to store grains because of the following reasons: High temperature and high moisture affect grain quality and can cause rapid decline in germination, colour, oil composition, and many other characteristics of grains. … High temperature and moisture favour development of insects and moulds.

How do biotic and abiotic factors affect the crop production?

Biotic factors such as pests, insects and diseases reduce the crop production. … Weeds also reduce crop productivity by competing with the main crop for nutrients and light. Similarly, abiotic factors such as temperature, wind, rain etc. affect the net crop production.

What is importance of storage of food grains?

The food grains obtained by harvesting the crops are dried in the sunshine before storing to reduce their moisture content.It is necessary to prevent them from spoilage. The higher moisture content in food grains promotes the growth of fungus and moulds on the stored grains which damages them.
