To investigate the effect of nitrogen sources and amounts on yield and yield components, cucumber was tested as a split plot with a completely randomized design of blocks with two factors in Ilam Agricultural Research Center in 2006. The effects of pure nitrogen at three levels of 0, 50 and 100 kg / ha as well as leaf feeding at five levels (urea nutrient solution in three concentrations, Fosamco nutrient solution in one concentration and control) on the quantity and quality of autumn cucumber of Super Damnius cultivar were studied. . The results showed that nitrogen application had no significant effect on yield, plant length, total fruit number and fruit dry matter percentage. The effect of nitrogen on fruit and plant dry matter percentage was significant. The effect of leaf nutrition on the yield of total fruit, total number of fruits and plant length was not significant and on the percentage of dry matter of fruit and plant was not significant. The interaction effect of nitrogen fertilizer in soil and leaf nutrition on the yield of total fruit, total number of fruits and plant length was not significant and on the percentage of dry matter of fruit and plant was not significant. According to the results of this study, the treatment of 100 kg / ha nitrogen and urea nutrient solution had the highest yield of 7.5 per thousand and was recognized as the best treatment.
