      abstract = {Average tea yields in China are low by international  standards and are extremely low when compared to yields  obtained on experiment stations.  This paper reports on a  ten year plant density trial undertaken by the Tea Research  Institute in Hangzhou, Zhojiang Province.  The green tea,  vegetatively propagated, clonal variety used in the trial  is called "Longjing 43".  At the high densities used, this  variety has yields more than ten times greater than the  average for Zhejiang Province.  Four different plant  density levels were used in the trial.  The economic  analysis examines the performance in terms of conventional  investment criteria: SNPV, Perpetual Annuity, B/C ratio,  IRR and the Discounted payback period.  The optimum time to  prune is also calculated for each of the trials and  sensitivity analyses are undertaken using various  assumptions as to the relative performance farmers might  attain.},
