Introduction In this second part of the study on forms of crop plants, we shall study the meaning of pollination and fertilizers. Pollination Pollination is the process by which pollen is transferred from the anther (male part) to the stigma (female part) of the plant, thereby enabling fertilization and reproduction. This takes place in the angiosperms and flower-bearing plants. What is the function of pollination? Like humans, many plants require a male element and a female element to “breed” or produce a new seed. The difference is that plants possess both the male element and the female element in the same flower. The male is the anther which produces a powder or dust called pollen and the female is called...

Introduction In this part, we study the Root/Shoot and Structure and Function of each part of a flowering plant. Your basic vascular plant parts are roots, shoots, stems, and leaves. Of course, there’s a wealth of variety within these types or parts, but it boils down to those four. Each part has distinct functions. Together, these parts reflect how vascular plants evolved to inhabit two distinct environments at the same time: the soil and the air. Why would plants do such a thing? The soil offers water and vital minerals. The air offers carbon dioxide and the energy of sunlight. To forge the successful lifestyles they enjoy today, plants evolved systems to tap into all these resources, both above and...

Agriculture is a broad science with many branches which are explained below: Animal Science: Animal Science is described as “studying the biology of animals that are under the control of mankind”. Wildlife Conservation: Wildlife conservation is the practice of protecting wild plant and animal species and their habitats. Among the goals of wildlife conservation, they are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife and wild lands to humans....

The two major types of agriculture are Commercial Agriculture and Subsistence Agriculture Commercial (Industrialized) Agriculture: Commercial or Industrialized farming occurs when a farm is set up for the sole purpose of producing crops and farm animals for sale, with the sole intention of making a profit. In this type of agriculture, large quantities of crops and livestock are produced through industrialized techniques for the purpose of sale. The goal of industrialized agriculture is to increase crop yield, which is the amount of food that is produced for each unit of land. Crops and livestock made through this type of agriculture are produced to feed the masses and the products are sold worldwide....

Introduction Agriculture is defined as the cultivation of the land to produce crops and the rearing of animals for man’s use. Agriculture has many branches. The form of agriculture practiced in an area depends on the size of the farm, purpose, availability of land, the type of soil in the area, topography of the land and the prevailing climatic condition. Crop Farming A crop is a plant grown for a specific purpose. Farming is the centre of activity where land is cultivated for the production of either plants or animals or both. Crop farming therefore involves the cultivation of land for the production of useful crops for the benefit of man. When different types of crops are planted on the...
