In: Minufiya journal of agricultural research 2013.v.38(3)P.1Summary: This investigation was conducted at AfricaRice Sahel Regional Station, Saint Louis. Senegel during two Wet seasons, (July - November) 2010-2011. To evaluate the performances of 14 rice varieties under low input fertilizer levels. Five fertilizer compound treatments were used in this study,were used in this study, F0: control (without any application), F₁= (37.5 - 4.4 - 8.3 kg N-P-K/ha⁻¹), F₂= half dose of the recommend application in Senegal (75 - 8.75-16.5 kg N-P-KI ha⁻¹), F₃= (112.5 - 13.3-24.8 kp' N•P-KI ha⁻¹) and F₄: recommended application in Senegal (150 - 17.5 - 33.0 kg N-P-K/ha⁻¹). The results indicated that both of year, genotypes exhibited significant effect for all studied traits. Also fertilizer levels exhibited significant effect for all studied traits except, panicle length and 1000 grain weight. Interaction of Year* Fertilizer levels and Year* varieties revealed significant differences for most of the studied traits. There are no significant effect of the interaction of fertilizer levels*varieties and Year*fertilizer levels*variety.
