Abstract

The main aim of all agricultural research workers is focussed on the problem of maximisation of crop production with minimum cost. Evolution of yielding strains, formulation of economical and profitable manurial programmes, utilisation of abour-saving implements, economic use of water for irrigation and tapping to the maximum extent all the avilable irrigational sources including underground water, have all received their legitimate and proper attention at the hands of agricultural research workers in different parts of the country. Of late a relative study of the merits and demerits of the method of cultivation adopted in different countries has also received their attention. The adoption of the Japanese method of rice cultivation in India is a typical example of this aspect of agricultural research.
