THE EFFECT OF RHIZOBIUM INOCULATION AND NITROGEN APPLICATION ON VARIOUS AGRONOMICAL AND QUALITY CHARACTERISTICS OF PEANUT GROWN AS A MAIN CROP

Abstract

The objective of this study was to determine the effect of nitrogen fertilizer and bacteria inoculation on some agronomic and quality characteristics of Halisbey peanut cultivar. This study was conducted at the Applying and Research Area of Field Crops Department, Faculty of Agricultural, Çukurova University in 2015 and 2016. The experimental design was a randomized block design. 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 study, the pod yield varied between 4702-6009 kg ha-1 . The highest pod yield was obtained from 200 kg ha-1 (6009 kg ha-1 ) nitrogen and 200 kg ha-1 nitrogen + bacteria (6001 kg ha-1 ) applied plots. The lowest pod yield (4702 kg ha-1 ) was obtained from control plots (without N and B). Pod number per plant, pod weight per plant, 100 pod weight, protein, oil ratio and pod yield per ha were affected by the160 and 200 kg ha-1 nitrogen applications. Also, the highest protein ratio was obtained from the 240 kg ha-1 nitrogen and bacteria inoculation.
