PhD. FERRİN FERDA AŞIK
Abstract
This study aims to determine the effect of bacteria and nitrogen dose applications on the harvest maturity index in peanut plants. The experiment was set up in a randomized block design with two factors. In the study, the first factor was Rhizobium bacteria, and the second factor was nitrogen doses (0, 40, 80, 120, 160, 200, and 240 kg N ha-1). In this study, the harvest maturity index was measured. The harvest maturity of the pods was determined according to the "peeling method" and when 60% of them were ripe, the harvest was carried out on 17 September 2015 and 3 October 2016. It was determined that nitrogen fertilizer and bacteria application at 160N (70.5%) and 160N+B (70.8%) doses gave the highest value and were effective on harvest maturity. The lowest harvest maturity index values were found in Control (56.8%), 240N+B (57.4%), and Bacteria (57.5%) applications. It was determined that increasing nitrogen dose over 160 kg N ha-1 and bacterial application decreased the harvest maturity index values.
