Abstract:

This study was conducted in order to determine the effects of the different plant frequencies, created by the double-arranged methods in the main product conditions of the Çukurova region, on some important agricultural and quality characteristics of the varieties of land crops (Arachis hypogaea L.) with different growth characteristics. In the study, two different species of Virginia type, NC-7 (crowd) and Halisbey (half-crowd) with different growth properties, were used as material. The study was organized to create six different plant frequencies (21.052, 19.047, 14,000, 12.666, 10.526 and 9.523 pieces and-1) according to two different double sequential October methods (70-25-70 and 80-25-80) and four different sequential distances (5, 10, 15 and 20 cm). Research; Ziraat Faculty of the University of Çukurova, the field plants department test ground in 2017 and 2018 years, was established and carried out according to the test pattern of divided parsels. In the fields used in the study, important characteristics such as the number of fruit per plant, the weight of fruit per plant, the weight of 100 seeds, the internal ratio, the fruit productivity, the protein ratio and the fat ratio were studied.The study found significant differences in the characteristics of the varieties tested according to the different plant frequency. The number of plants in the unit area has increased significantly in the values of properties such as the number of fruit per plant, the weight of fruit per plant, the weight of 100 seeds, the internal proportion and the fat proportion. Decara fruit productivity values, according to the plant frequency created according to the October method, have been different in both species of landfruit, and in terms of this characteristic the highest average value (668,3 kg to-1) of plant frequency is obtained from crops made as 12,666 pieces to-1 (80-25-80x15 cm of October frequency).
