manure or fertilisers are also do not show any positive trend. The major cost<br />

comp<strong>on</strong>ent would be labour cost <strong>for</strong> plucking the palms. IrrigClti<strong>on</strong> has not<br />

been effective in augmenting the yield <strong>and</strong> the <strong>on</strong>ly effect was that irrigati<strong>on</strong><br />

lengthened the age at which yield decline set in or prol<strong>on</strong>ging the peak<br />

bearing period.<br />

Thus, the absence <str<strong>on</strong>g>of</str<strong>on</strong>g> timely, adequate <strong>and</strong> dependable irrigati<strong>on</strong> 25<br />

facilities has been identified as <strong>on</strong>e <str<strong>on</strong>g>of</str<strong>on</strong>g> the major c<strong>on</strong>straints <strong>for</strong> the adopti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

technologies developed by the research stati<strong>on</strong>s in the state. In the absence <str<strong>on</strong>g>of</str<strong>on</strong>g><br />

timely <strong>and</strong> adequate irrigati<strong>on</strong> facilities, the agriculture sector in the state is<br />

c<strong>on</strong>strained by lower levels <str<strong>on</strong>g>of</str<strong>on</strong>g> intensity <str<strong>on</strong>g>of</str<strong>on</strong>g> input use as widely reported<br />

elsewhere (Narayana, 1989; Geethakutty, 1993) as also brought out by the lack<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> corresp<strong>on</strong>dence between input use <strong>and</strong> net irrigated area in the state (Figure<br />

7.3).<br />

25 The lack <str<strong>on</strong>g>of</str<strong>on</strong>g> irrigati<strong>on</strong> <strong>for</strong> coc<strong>on</strong>ut can partly be explained by the pol icy followed by<br />

the government regarding investment in irrigati<strong>on</strong>. The bulk <str<strong>on</strong>g>of</str<strong>on</strong>g> the government<br />

expenditure <strong>on</strong> irrigati<strong>on</strong>, which came to about 16 per cent <str<strong>on</strong>g>of</str<strong>on</strong>g> the plan expenditure <strong>on</strong><br />

an average during the plan periods, has been <strong>on</strong> medium <strong>and</strong> major projects <strong>and</strong> most<br />

<str<strong>on</strong>g>of</str<strong>on</strong>g> these projects were designed <strong>for</strong> irrigating low lying paddy l<strong>and</strong>s (Narayana <strong>and</strong><br />

Nair, \983).<br />
