The research was conducted at the Agriculture Research Farm, Faculty of Agriculture, University of Suez Canal, during the sesame growing seasons of 2011 and 2012. For studying the impact of insect pollination and nitrogen fertilization on sesame production, the experiment was divided to 13 treatments of open pollination and non open pollination, with three different levels of ammonium nitrate (NH 4 NO 3) and one level of seryalin as bio- fertilizer. Non opened pollination treatments were covered before the start of flowering period with a perforated net bag, to allow the air to pass through and to prevent insects from approaching the plants. Quantitative and qualitative indicators, were measured as follows: rate of capsule per plant, capsule weight, rate of seeds in each capsule, weight of 1000 seeds, germination (%), seedlings vigour and oil content (%). Results clearly demonstrate that qualitative and quantitative indicators of sesame crop was significantly increased with opened pollination and with the increase of nitrogen fertilizer level up to 40 kg N/ feedan -1 plus or minus seryalin, in reclaimed sandy soils, in Ismailia, Egypt
