Perhaps you should try some spelling variations:
international journal » international capital
irrigation schemes » irrigation scheme, irrigation systems
rate international » rates international, trade international, raise international
canal irrigation » scale irrigation
supply canal » supply annual, supply rural, supply case
supply rate » supply water, supply case, supply data

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( supply canal irrigation schemes. ) OR ( supply rate international journal. ))~".
• Adding a wildcard symbol may retrieve word variants: (( supply canal irrigation schemes. ) OR ( supply rate international journal. ))*.
