 Better varieties means better yield, more say maybe sometimes better form or better quality of proteins or better quality of other products like eggs or milk. The biologists actually study the life cycles and the data about races of different organisms like cows, like buffaloes, like goats or other organisms and through improved breeding techniques we can use better varieties which can yield more proteins, which can yield more milk or which can yield more eggs for us. Very importantly in farming, in poultry and dairy farming diseases are a major factor which can sometimes destroy the whole form, the whole form of the animals. In disease control, biology helps us because biologists, they are the scientists of the living organisms, they study the mechanisms of disease, they study the treatments of their diseases and they can tell different the causes of the disease that this disease is caused by this particular maybe organism, maybe chemical, maybe food or something else, they also can help us in making their treatments. So in dairy and poultry, we can also make better feed for these organisms, we can control diseases, we can make better varieties to get more yield and better products. Now the apiculture, honey bee keeping, honey bees are also kept by people from centuries. People grow them for getting honey, large honey bees, small honey bees, both are cultured. Honey bee, we know that biology tells us that honey bees are social insect and it makes colonies. There is a queen bee which lays eggs, there are drones which are males and which fertilize these eggs and there are workers, the worker bees, which actually collect the nectar from different flowers and convert it into honey. Biology helps us in improving the varieties of honey bees that we can improve better variety, we can provide them with some specific flowers which have more nectar, for example, which is a better nectar for them and also we can help, biology can help us in the disease control. The biologists also tells us, does the farmers that how to deal with these honey bees, that is at which time they can collect honey and how can we deal with the honey bees, so that they do not harm them and they can collect the honey. So biology is very useful, in biological knowledge is very useful in honey bee farming which is called technically apiculture, here we can see a farmer collecting, separating honey bees from its home, house, then comes the biological pest control, we can control the pests which are attacking our crops or which are attacking our animals, dairy or poultry farms by biological means, what is a pest? A large number of organisms damage our crops or damage our animals by acting as parasites, attacking upon them, these are called pests, for example rats, rats are the pests of different types of crops, ticks and mites, they are we can call them pests or we can we actually call them parasites upon buffaloes and cows. There are lot many insects which commonly attack our crops and destroy our crops. We control these insect pests by various means, initial old method was a crop rotation that is we change our crop in different seasons, that is once we grow another crop, second time we grow a different crop, we use chemical controls, we put different types of chemicals on our crops to control the insects, but insects become resistant and also these chemicals are dangerous for our crops, biological control is a much much better method. We can actually use the natural predators of the pests to control these organisms, that is we introduce the predator of the pest in that field and these predators can eat upon those pests, the result is our crops are safe and the benefit of this biological control is this, that this is a permanent control, that is those predators which are introduced, they will stay there and they will control the crops, control the pests in maybe next year or for long term, secondly these are safe, they are not chemicals, they are organisms, they do not harm our environment or harm our crops, but this is extremely important in the selection of a biological control mean any of the organism that it should be safe for our environment, that it should not happen that they eat upon the pest and they also eat upon our crop, so selection of a biological control method is also extremely important. Now applications of biology in growing crops and plants, as we know that plants are producer part of the ecosystem, they are very important, we grow them as food crops, we grow them as other cash crops like cotton and others, we get different products like vegetables, we get wheat, we get perfumes, we get medicines and furniture from the plants, they are duty of the nature, they are ornamental plants, how biology help us in growing crops, number one we can provide them with more suitable quantities of water, we can grow them in a better soil in which we know that they grow better according to their life cycles, we can add better means of their cross pollination or something else and we can control diseases, we can produce biogenetic engineering or some other method to make more resistant plants to the environmental stresses or different types of environmental changes, we can make better breeds of plants which give us better yield and which grows comparatively easily in comparison to the normal plants, the other plants, so the knowledge of biology helps us in different fields of life, starting from the pharmaceutical industry or health or medicine to the agriculture, to the animal culturing and to all other fields of life, there are lot many fields of life.
