A text book of agronomy
The challenges before the Agricultural Scientists of our country today are much more complex than even before. The first issue and the cause of some major problems in the future - the depletion of the ozone layer, threatens the inhabitants of Earth due to the advent of harmful ultraviolet radiation. The second issue - global warming and the plight of Antarctica, involves the melting of polar ice caps threatening our coastal regions in the future. Forecast of increase in average temperatures, higher sea levels and changes in rainfall patterns will all have a negative impact on crop production, especially in the tropics. Food production has to be increased to 240 m.t. within the next five years. To achieve the massive target, very little scope and possibility exist in respect of horizontal expansion. Crop production and production technologies are of almost important for successful and economic cultivation of field crops. Under these circumstances, important and relevant informations are collected and compiled in a book form titled ``A Textbook of Agronomy``.
