A field experiment was conducted at the ICARDA sub-station, Terbol, Lebanon to determine the effect of phosphorus and nitrogen fertilization and Rhizobium inoculation on the nodulation, yield, and protein content of the locally adapted lentil cultivar "Syrian local large". The insecticide carbofuran was also used to reduce serious nodule damage caused by Sitona larvae and thus increase available nitrogen. The soil at Terbol proved to be highly fertile in major nutrient elements; phosphorus and nitrogen fertilizer application would be unnecessary, since it did not increase nodulation, yield, or protein content. Inoculation with Rhizobium was also found unnecessary because the local rhizobial population seemed to be efficient and sufficient for nodulation. Carbofuran did not increase yield, but it did increase (1) nodule mass by significantly reducing Sitona nodule damage, and (2) seed protein content slightly, which increased protein yield/hectare
