Growth and Yield Responses of Pot-Grown Long Bean and Luffa to Nitrogen Rates

Optimizing nitrogen (N) input rates for vegetable production is crucial in Florida to reducing costs and enhancing environmental sustainability. Asian vegetables emerging expanding not only increase profit growers, but also enhance food diversity consumers. The objective of this study was gain a better understanding the partitioning usage N carbohydrates two crops: long bean (Vigna unguiculata ssp. sesquipedalis (L.) Verdc.) angled luffa (Luffa acutangular Roxb.). Four (0, 0.91, 1.36, 1.81 g pot−1) were compared high tunnel trial understand influence fertilization on crops. For bean, plant biomass highest at input, N-fertilized plants had significantly higher leaf greenness than control flower initiation mid-reproductive stages. However, inputs no apparent effect yield, use efficiency (NUE), blade total concentration, roots (length, volume, dry biomass, root-to-shoot ratio), or nodules (number plant−1 biomass). luffa, greater fruit number, stages, although there significant difference shoot content, NUE among treatments. Within range these rates, our results suggest that promoted vegetative growth whereas reproductive luffa. This highlights differences sink–source relationship tunnel, which can guide decisions crops are rapidly USA.
