R.  aEstimate the number of papaw (Cariaca papaya) trees required for reliable yield data.  c1969  aStatistics on twice-weekly havesting of 4, 6, and 10 papaw trees in plots of 2, 3 and 4-year old trees in a continuous 4-year crop cycle showed that tree number and its interaction with treatments were nonsignificant. Harvesting of 4 trees only for yield data will save labor, and since plot size and attendant guard row trees can be correspondingly reduced, further savings in land, labor and materials can be realized.1 aPLUCKNETT, D.
