Comparative Proximate Composition of Six Sesame (Sesamum indicum L.) Accession Cultivated in Katsina State, Nigeria

Abstract

Sesame (Sesamum indicum L.), known locally as beniseed, is a major oilseed crop in Nigeria. This study evaluated the proximate composition of six sesame accessions (IGBOHO BLACK, 02M, E8, EXSUDAN, KENAN 4, and BOGORO LOCAL) to identify nutritionally superior lines. Proximate analyses (moisture, ash, crude protein, crude fiber, fat and oil, and carbohydrate) were conducted using standard methods. One‑way ANOVA indicated significant differences among accessions for all traits (p ≤ 0.05). IGBOHO BLACK and E8 recorded the highest moisture contents (3.40 ± 0.10% and 3.38 ± 0.00%, respectively). IGBOHO BLACK had the highest ash (5.98 ± 1.10%) and crude fiber (5.77 ± 1.10%), while E8 showed the highest crude protein (7.21 ± 0.20%) and highest fat and oil content (60.50 ± 1.40%), closely followed by KENAN 4 (60.46 ± 2.13%). Carbohydrate content was greatest in IGBOHO BLACK and BOGORO LOCAL (27.63 ± 1.30% and 27.62 ± 1.18%, respectively). The accessions IGBOHO BLACK and E8 had favorable levels of moisture content, crude fibre, protein, fat and oil, carbohydrates that suggest they are promising accessions for nutritional and economic value, followed closely by KENAN 4 and BOGORO LOCAL. Further evaluation of Sesamum indicum L. under different environments and yield trials is recommended for breeding and cultivation purpose.
