Fertilizers are commercially prepared chemical compounds that are used as plant nutrients to promote growth.
They are used to ensure good vegetative growth (leaves, branches and flowers), giving rise to healthy plants.
Fertilizers can be organic (composed of organic matter), or inorganic (made of simple, inorganic chemicals or minerals).
They are usually applied either through the soil, for uptake by plant roots, or by foliar feeding, for uptake through leaves.
Fertilizers should be applied carefully in terms of proper does, time, and observing pre and post- application precautions for their complete utilization.
Water is important for proper growth and development of plants and is absorbed by the roots from soil. The level of water in soil is maintained by rain. However the rainfall doesn’t occur all the time so supply of water in fields is required to be managed so as to improve the productivity.
The process of supplying water to crops through different sources at different intervals by human efforts is called irrigation.
The time and frequency of irrigation varies from crop to crop.
Ensuring that the crops get water at the right stages during their growing season can increase the expected yields of any crop.
It is related to raising crops that help in obtaining maximum benefit from the same piece of land. Growing different crops in same piece of land reduces the risk of crop failure, disease and infestation. It can be done in different ways.
