The objective of this study was to determine the effect of nitrogen fertilizer levels on the performance of an eggplant (Solanum melongena L.) and sweet pepper (Capsicum annuum L) intercropping system in open field at four different levels (0, 50, 100 and 150 ㎏/㏊). Plant height, lateral stem length, leaf chlorophyll content, days to 1st flowering, flower number, fruit weight and plant yield were assessed. Results of this study indicated that nitrogen fertilizer increased some growth characteristics (plant height, lateral stem number, and leaf chlorophyll) of eggplant and pepper in intercropping system. Nitrogen fertilizer affected eggplant flowering factors (flower number and days to 1st flowering). Days to 1st flowering decreased by nitrogen treatments and treated plants flowered earlier than control. It was observed that fertilization with 50 ㎏ N ㏊-1 resulted in the best fruit weight and plant yield for both eggplant and pepper in intercropping system.
