we mowed the grass and broadleaf weeds under Jerseyland peach 

 trees 5 or 6 times annually they were generally lower in nitro- 

 gen, made less growth, and produced less fruit than those re- 

 ceiving annually 40 lbs. of hay, 2 applications of paraquat, 1 

 application of paraqua t-plus-s imaz ine mixture, or cultivation. 



Peach trees produce well under the sod-plus-mulch system 

 of soil management in Massachusetts. An annual application of 

 a 40-lb. bale of hay under peach trees can produce growth and 

 yields comparable to those produced by cultivation. However, 

 mulch generally increases leaf potassium in comparison to culti- 

 vation, which may then depress leaf magnesium and calcium.
