Abstract

Studies were undertaken during 2002–2003 to assess the production and distribution of dry matter at different stages of growth in response to the split application of nitrogen and Azospirillum in the banana cv. Rasthali. The results revealed that application of Azospirillum and higher amount of nitrogen had an apparent effect on dry matter production. The dry matter production was rapid from small to harvest stage and it was remarkable after shooting due to bunch development Leaves showed increase in dry matter upto shoot stage but thereafter there was a decline since there was no development of new leaves after flowering. The dry weight of the corm rose from initiation to shooting and after shooting the weight tended to drop. Pseudostem increased in weight upto shooting and thereafter either remained the same weight or tended to increase. Among the fruiting organs, fruits themselves naturally increase in dry weight after shooting as also did the external part of the fruit stalk.
