The effect of bacteria (Rhizobium sp.) and nitrogen fertilizer applications on some agricultural and quality characteristics of peanut grown as a main crop

This study was conducted at the research area of Field Crops Department in Çukurova University, Agricultural Faculty in 2015 and 2016. The experimental design was Randomized Completed Bloc. The objective of this study was to determinate the effect of nitrogen fertilizer and bacteria inoculation on some agronomic and quality characteristics of Halisbey peanut cultivar. In this study, seven (0, 40, 80, 120, 160, 200 and 240 kg ha-1) different nitrogen doses and Rhizobium bacteria were used. As a result of this study, the pod yield varied between 4702-6009 kg/ha. The highest pod yield were obtained from 200 kg ha-1 (6009 kg ha-1) nitrogen and 200 kg ha-1 nitrogen plus (+) bacteria (6001 kg ha-1) applied plots. The lowest pod yield (4702 kg ha-1) was obtained from control plots (0 nitrogen applied plots). Pod number per plant, pod weight per plant, 100 pod weight, 100 seed weight, pod yield per ha, shelling percentage, oil yield and harvest maturity were affected by the160 and 200 kg ha-1 nitrogen applications. In addition, plant height, protein and oleic acid percentage were affected by the 240 kg ha-1 nitrogen and bacteria applications.
