Abstract :This research was conducted to determine the effects of different row distances and different doses of nitrogen and phosphorus on the grain yield, yield elements, morphological characteristics and some quality elements of two rye varieties (Yerli and Mercator) under Karapınar ecological conditions in 1989/90-1990/91. - It was carried out for the purpose of In this experiment, which was designed as \\\"factorial with two replications in randomized blocks trial design\\\", the distance between 4 rows was S1 (13 cm), S2 (16 cm), S3 (19 cm), S4 (22 cm) and nitrogen and phosphorus were used in 4 different ( 0, 3, 6 and 9 kg/da) doses were used. Maximum grain yield in the \\\"Local\\\" variety was obtained in the trial plots where 16 cm row spacing was planted (103 kg/da), 3 kg/da nitrogen (113 kg/da) and 6 kg/da phosphorus (106 kg/da) were applied; In the \\\"Merkator\\\" variety, it was determined in the trial plots where 16 cm row distance was applied (94 kg/da), 3 kg/da nitrogen (103 kg/da) and 6 kg/da phosphorus (97 kg/da) dose was applied. is. It was determined that the applied treatments had statistically significant effects on the harvest index, quality characteristics, yield elements and morphological characteristics of both rye varieties. In addition, statistically significant interaction effects were observed between the applied treatments on yield and other characteristics. In this research, it was determined that there were highly positive relationships between the number of grains per spike, grain weight per spike, spike length, plant height, bindane weight, harvest index and grain yield. In addition, positive relationships were found in multiple correlation studies between the research parameters considered and effective on grain yield. Rye ranks fourth among grains in our country in terms of cultivation area and production, after wheat, barley and corn. According to 1988 statistics, 191,000 tons of rye were produced in an area of ​​180,000 ha, and a grain yield of 156.7 kg/da was achieved. In our country, Central Anatolia ranks first in terms of rye cultivation area and production. In the Central Anatolia region, after Kayseri, Konya ranks second with a cultivation area of ​​29,951 ha and a production of 21,839 tons (Arnon, 1989). Especially the fact that Karapınar district is a place in Konya province that is open to wind erosion and has a semiarid microclimate, and rye is grown in large areas in the region, further increases the importance of this research. In Turkey\\\'s Karapınar district, which receives the least rainfall (300 mm), has light, organic matter-poor and low-fertility soils, and has severe wind erosion, optimum plant density and nitrogen and phosphorus doses in two rye varieties are related to grain yield, yield and flour. This study was carried out to determine the effects on the walls, quality and morphological features.
