BIOTIC FACTORS AFFECTING AGRICULTURAL PRODUCTIONBiotic factors that affects agricultural production simply means the living or biological factors that affect the production or practice of agriculture. Seven of the most important factors are listed here for you
The biotic factor like disease, insects and nematodes and abiotic factor like drought waterlogging, heat, could and frost have a negative inpect on crop production I.e. the crop field decrease due to this factors.
SOL ORGANISMSi. These include bacteria, fungi, earthworm, rodents and termite.
ii. Some, like bacteria and fungi can cause diseases
iii. Some aid the aeration of soil, percolation and fertilityroot nodule of plants can fix nutrients directly to plants and soil
v. Some open up wounds on plants or animals for other pathogen to enter
vi. Some reduce the quality or quantity of crops
vii. Some help in the decomposition of plant materials to form humus
PESTSi. These include birds, insects, rodents and some mammals
ii. The reduce the quality and yield of crops and animals
iii. The reduce the quality of animal yield
iv. Some are vectors or carriers of diseases
vi. The cost of their control increases the cost of production
Biotic factors such as pests, insects and diseases reduce the crop production. A pest causes damage to our crops by feeding. 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.
