dc.description.abstractThe present study detennined the dry matter (DM) requirement for potential growth (PGR), growth respiration (Rg) and maintenance respiration (Rm) of fru its, leaves, stem and root system of adult coconut palms (25-26 years) ofTall x Tall cultivar under resource-un lim iting conditions. The total OM requirement ofa palm was about 21 kg/palm/month and 63% of that total was required for growth and respiration of vegetative organs (leaves, stem and roots) whilst the rest (37%) was for fruits. Srmilarly, the DM required for respiration (62%) was nearly two third ofthe total requirement of a palm and the balance 38% was required for growth of organs. The total dry matter requirement (TOMR) of individual fruits varied with developing stage and TDMR offruits / palm varied between months and years depending on the fru it load of different development stages. Irrespective of the year, TOMR of fruits was highest during November to February (about 10-11 kg/palm/month) and lowest in June-July (about 5-6 kg/palm/month). However, the OM requirement of vegetative organs (a total of approximately 13 kg/palm/month) did not vary between months.en_US
