Participatory demonstration of integrated root (wilt) disease management practices in farmers' gardens - an impact study

Abstract

Integrated root (wilt) management practices are recommended by CPCRI for improving the health and productivity of coconut palms in root (wilt) affected areas. The recommended practices were adopted in 25 ha plots f 208 coconut farmers consisting of 5000 palms during 1999-2000 to 2002 - 2003. The result was demonstrated in a participatory mode involving farmers, members of households, farm women, scientists, extension workers and local leaders. The impact analysis indicated a remarkable reduction in root (wilt) disease intensity with an increase in average yield from 24.17 - 46.30 nuts/ palm/ year, i.e. 91.4% increase. The B:C ratio improved from 1.03 to 1.77. leaf rot disease found to be superimposed in root (wilt) affected palms could be managed very effectively (47.9% to 1.5% incidence). Effectiveness of rhinoceros beetle control and eriophyid mite management was also recorded. The technology demonstration was done with an appropriate extension methodology support. PRA techniques, recording of individual palm profile , informal group meetings, scientist - farmer interaction, research station visit, method demonstration/ training programmes for knowledge and skill upgradation were the major extension components adopted.
