The effectof two sources of nitrogen on plant growth, and fruit yieldofchile pepper (Capsicum annuumL.) cv. Sandia grown in greenhouse to increased salinity wereevaluated. An organic sourceextracted from grass clippings in rates of 120 and 200 kg N ha-1,and another inorganic (ammonium nitrate) in rate of 120 kg ha-1were combined with low, moderate and high (1.5, 4.5, and 6.5 dS m-1) salinity levels arranged in a randomized complete block design replicated four times. Salinity treatments reduced dry matter production, leaf area, relative growth rate and net assimilation rate but increased leaf area ratio.Mean fresh fruit yields decreased for each N rate and source combinations as soil salinity increased. The organic fertilizer producedhigherfruit yieldstan the inorganic fertilizer. The highest fruit yield was obtained with the increased rate of organic N. The fruit numberwas more affected by salinity than the individual fruit weight. This organic fertilizer may be an effective N source for chile pepper and other vegetable crops grown under non-and salt-stressed conditions.
