Tamil Nadu farmers are cultivating Jasmine flower (Tamil: Malligai) by Chemical way but couldn’t follow organic way( i.e. zero budget). If anyone succeed , please let me know the system or tips. Farmers are interesting to do organic but unable to manage in terms of growth, pest, season and weather related issue etc. Please help to resolve the above issues in organic way without using synthetic fertilizers.
