Abstract

A field experiment was carried out in Thanjavur District, Tamil Nadu, India with
six green manure crops to study their ability to grow and establish in the coconut
basin and to evaluate their effect on nut yield. Among the crops tested, Desmodium
tortuosum was found to be the best producing 12.8 kg of green leaf matter per basin
followed by cowpea (Vigna unguiculata) and sunhemp (Crotolaria juncea). The dry
matter production was also found to be superior in Desmodium compared to others.
Incorporation of Desmodium added 250 g of N per crop per basin which was the
highest. In situ cultivation and incorporation of Desmodium and sunhemp significantly
increased the nut yield of coconut.
