Description: This research was conducted in Erzurum in 1997-1998 and in unwashed conditions. The combination of application II, which consists of the combination rates of mixture of mercury, mercury and grain with different "mercury + mercury" and "mercury + grain" (% 100 mercury +% lO, 20, 30 and 40 grains) with single crops, has been tested in terms of productivity, productivity elements and "Earth Use Efficiency" (AKE). The production of mercury, grape and grape was achieved one per kg, respectively, 90.3, 144.0 and 124.1 kg. The output of a mercury was higher than the "mercury + grain" mixture in the "mercury + grain" mixture. In the form of the two mixture, due to the increase in the grass proportion in the mixture, the number of backs per plant, the number of plants in m2, the weight of 1000 and the yield of one significantly decreased; the number of backs in m2 and the yield of one increased; the number of backs in m2 and the yield of one increased. The highest ACE value was found from the application "100% grain + 10% grain" 67.1 kg/day grain and 34.8 kg/day grain production was obtained. The results showed that in Erzurum’s ecological conditions, the mixed crops and grains are not hopeful in the direction of one production and ACE. YIELD AND YIELD COMPONENTS IN LENTIL + CEREAL MIXTURES SUMMARY: This study was conducted in order to investigate yield, yield components and "Land Equivalent Ratio" (LER) in lentil alone or in mixtures with barleyand wheat (100% lentil + l0, 20, 30 and 40% cereal) under dry conditions of Erzurum in 1997 and 1998. Pure stands of lentil, barleyand wheat gave grain yields respectively of9O.3, 144.0 and 124.1 kg/day. Lentil yield in "Lentil + wheat" plots was higher ıhan in "Lentil + barley" plots. In both types of mixture pod number per plan, plan number per m2, 1000 grain weight and grain yield of lentils significantly decreased whereas ear number per m2 and grain yield of barleyand wheat increased depending on the increases in the percentage of cereals. In the mixture of "100% lentil + 10% wheat" that gave the highest LER value lentil and wheat produced 67.1 and 34.8 kg/day grain yields respectively. Lentil and cereal mixtures did not presenI promising results in terms of official and LER under Erzurum conditions.
