SUPPORT CROPS
Plant Agathi (Tamil) (Sesbania) tree near Banana trees.  Keep cutting Agathi branches and feed cattle.  When this tree is nearby, plantains give good yield.  Agathi absorbs Nitrogen from atmosphere and stores it in it roots.  No other plant can compete with it in this work.  Any plant can be grown under Agathi with benefits.  Gourds, Bitter gourd and Snake gourd creepers can be grown with more yield under Agathi.  Even Betel plant can be made to spread under Agathi.
