Nitrogen Management and Its Impact on Yield, Oil Quality, and Sustainability of Second-Crop Sesame (Sesamum indicum L.) in the GAP Region

Abstract

Nitrogen management is crucial for optimizing the yield, oil quality, and sustainability of second-crop sesame (Sesamum indicum L.) in the GAP region. This study investigated the effects of different nitrogen application rates (0, 4, 8, and 12 kg N da⁻¹) on the agronomic performance, seed yield, oil content, and fatty acid composition of sesame. A field experiment was conducted during the 2020 growing season using the locally developed cultivar Hatipoğlu. This study was conducted as a completely randomized block design (RCBD) with three replications. The results showed that nitrogen fertilization significantly (p<0,05) enhanced plant height, number of branches, number of capsules, capsule length, seed yield, and oil content. The highest seed yield (1756.6 kg ha⁻¹) and oil content (50.98%) were obtained with the application of 12 kg N da⁻¹. However, nitrogen rates had no significant effect on protein content and most fatty acid ratios, except for linoleic and linolenic acids. Correlation analysis revealed strong positive associations between morphological traits (capsule length, number of branches, and number of capsules) and both seed and oil yields. These findings highlight the importance of balanced nitrogen management for improving sesame productivity and resource-use efficiency under the agroecological conditions of the GAP region. This study provides practical guidance for breeders in selecting responsive genotypes and for farmers in optimizing nitrogen fertilization strategies to promote sustainable sesame production.
