The productivity <str<strong>on</strong>g>of</str<strong>on</strong>g> crops such as coc<strong>on</strong>ut, arecanut <strong>and</strong> banana have shown<br />

declining trend in some <str<strong>on</strong>g>of</str<strong>on</strong>g> the schemes, which implies that these crops are highly<br />

sensitive to moisture stress.<br />

This reflects up<strong>on</strong> the increasing water scarcity<br />

experienced in the irrigati<strong>on</strong> schemes during summer.<br />

The mean yield <str<strong>on</strong>g>of</str<strong>on</strong>g> paddy during summer in five completed projects IS<br />

compared with the yield during the other two seas<strong>on</strong>s <strong>and</strong> the overall yield levels <strong>for</strong><br />
