Muskmelons (Cucumis melo L.) were transplanted through clear plastic mulch on May 22, 1981, with 45, 90, 135, or 180 kg N/ha applied either preplant broadcast incorporated or injected through the trickle system. Seventy percent of the N rate was injected by flowering (June 23) and the remaining 30% from June 23 to July 27, just prior to first harvest. Muskmelon petiole NO 3 -N concentration increased linearly with increasing N rates on all sampling dates for both application treatments. Trickle injected N resulted in a significantly higher plant N0 3 -N petiole concentration on June 22. Later in the season, July 13 and August 3, there were no petiole NO 3 -N concentration differences between the application methods. Marketable early and total yields were not affected by the N rate or application method; but 265
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
