<h1><strong>AGRO-ALLIED INDUSTRIES AND RELATIONSHIP BETWEEN AGRICULTURE AND INDUSTRY</strong></h1> CONTENT <ol> <li>Meaning of Agro-allied Industries</li> <li>Agro-allied Industries and their Raw Materials</li> <li>Industries that Produce Farm Inputs</li> <li>Relationship between Agriculture and Industries</li> </ol>   <h2><strong>Meaning of Agro-allied Industries</strong></h2> The term <em>agro-allied industries</em> refers to industries that make use of agricultural produce or products as raw material to produce other finished products. It also refers to the produce that the farmers use as an input in the farm. The continuous existence of these industries is made possible through the raw material derived from agriculture. These industries help to; <ol> <li>provide market for agricultural products;</li> <li>provide employment opportunities;</li> <li>generate income for the government;</li> <li>influence or enhance development of rural areas;</li> </ol>   <h2><strong>Agro-allied Industries and their Raw Materials</strong></h2> The following industries make use of agricultural produce or products as raw materials:

Pests of Crops

<h1>PESTS OF CROPS</h1> CONTENT <ol> <li>Meaning of Crop Pests</li> <li>Classification of Crop Pests</li> <li>Name and Description of Important Insect Pests</li> </ol>   <h2>Meaning of Crop Pests</h2> A pest can be described as an organism, whether plant or animal, which causes economic damage to crop plants, livestock, man and his possessions. They attack crops on the field as well as in the store. They may harm crops directly or introduce diseases into them. Examples of pests are insects, rodents, higher parasitic plants, etc.   <h2>Classification of Crop Pests</h2> Pests are classified in different ways as follows: <ol> <li>Insect pests</li> <li>Non-insect pests</li> </ol>   <h3>Insect Pests</h3> These are the most serious pests of agricultural importance, and the group includes all insects which cause damages to crops and crop products. Examples of insect pests are grass hopper, weevils, beetles, white flies, termites, crickets and locusts. They feed on crops either on the field or in the store.   <h3>Non-insect Pests</h3> These are organisms other than insects which attack and feed on crops.

<h1><strong>ENVIRONMENTAL FACTORS AFFECTING AGRICULTURAL PRODUCTION</strong></h1> CONTENT <ol> <li>Introduction</li> <li>Climate Factors</li> <li>Biotic Factors</li> <li>Edaphic Factors</li> </ol>   <h2><strong>Introduction</strong></h2> Agricultural activities such as crop and livestock production are affected by several environmental factors. These environmental factors determine and influence the distribution of crops and livestock as well as the performance and productivity of crops and livestock.   <h2><strong>Climatic Factors </strong></h2> Climate can be defines as the average weather condition of a place measured over a long period of time (over 35 yrs). Elements of climate include temperature, sunlight, wind, rainfall, relative humidity, pressure, radiant energy and cloud cover. <h3><strong>Temperature </strong></h3> This is the degree of hotness or coldness of a place at a given time. The effects on plants and animals include; <ol> <li>It is essential for germination.</li> <li>It is essential for growth of plants.</li> <li>It is necessary for photosynthesis.</li> <li>It affects distribution of crops and animals.</li> <li>It affects maturity of crops i.e; ripening of fruits.</li> <li>It also determines the rate of evapo-transpiration.</li> </ol> <h3><strong>Sunlight</strong></h3> Plants need sunlight to grow.
