    (AAU J. Physical & Applied Sciences, 2025) Olayinka, B. U.; Lawal, A. R.; Abdulkareem, K A.; Kareem, I.; Babatunde, M. O.; Ayinla, A.; Sagaya, A.; Mustapha, O. T.
    Groundnuts have been established to have great health benefits due to their biochemical constituents. Varieties abound, differing in their quality of seed and oil characteristics; hence, the need to continually assess the characteristics of the seeds, most importantly the improved varieties, whose chemical composition and physico-chemical properties are scant in the literature. In this study, the proximate, mineral and physico-chemical properties of five groundnut varieties (KAMPALA, SAMNUTS 23, 24, 25 and 28) were evaluated using standard procedures. The results revealed that crude protein, fat and fibre were higher in SAMNUT23 when compared to other varieties. Aside from ash and carbohydrate, the KAMPALA variety recorded the lowest values of all parameters. Regardless of varietal differences in mineral elements, the seeds were rich in phosphorus, sodium, potassium, and magnesium, compared to other essential elements such as zinc, iron, copper, and nitrogen. However, the mineral elements were significantly higher in SAMNUT varieties when compared to KAMPALA. The physico-chemical properties did not show appreciable differences except for acid value, iodine value and saponification values, which were significantly lowest in SAMNUT28. The findings revealed that all the SAMNUTvarieties, especially SAMNUT23, 24 and 25, had superior quality; hence, their use in seed certification, food processing and breeding programmes within the groundnut value chain in Nigeria should be encouraged.

    Composition of Coconut (Cocos nucifera L. Cv. Fiji Dwarf) Edible Endosperm and Physicochemical Properties of its Oil
    (Federal University of Kashere-Nigeria, 2021-08-15) Abdulkareem, K.A; Olayinka, B.U; Lawal, A.R.; Adeniji, O.A; Ibuowo, M.B; Jacob, O.E; Abdulra'uf, L.B; Kareem, I.; Aboyeji, O.O; Mustapha, O.T; Etejere, E.O
    Coconut (Cocos nucifera L.) is one of the most important oil producing crops in the world. It has enormous industrial and health benefits. To affirm the foregoing, the proximate and physicochemical constituents of the oil extracted from the edible endosperm were determined. The results showed that percentage moisture, protein, ash, crude fat, crude fibre and carbohydrate had respective values of 42.39 %, 6.21 %, 1.04 %, 17.18 %, 8.95, and 23.69 %. The edible mesocarp has high amount of mineral elements such nitrogen, potassium, calcium and phosphorus. Whereas, elements such as sodium, manganese, magnesium, copper and chlorine occurred in low quantity. The physicochemical properties of the oil showed a refractive index of 1.46, specific gravity of 0.92 g/cm3, acid value of 2.15 %, free fatty acid of 1.08 %, saponification of 125.980 mgKOH/g and iodine value of 2.89 indicating that the oil is good for consumption. Given, the results of proximate and mineral compositions, the edible endosperm could therefore be considered as good source of energy and alternative source of dietary supplement for human nutrition.

    Effect of phosphorus fertilizer and shoot pruning on growth, yield and fruit quality of tomato (Solanum lycopersicum)
    (Indian Journal of Agricultural Sciences, 2023) Olayinka, B. U.; Oyewole, M.; Jacobs, O. E.; Abdulkareem, K. A.; Lawal, A. R.; AbdulRauf, L. B.; Kareem, I.; Muhammed, G. Y.; Abdulbaki, A. S.
    Phosphorus fertilization or pruning as sole practice has been established to enhance tomato yield. However, there is a dearth of knowledge when both practices are combined. Under potted experiment, two tomato varieties (Tomato 82-B and Local) were subjected to 13 treatment combinations of phosphorus fertilization and pruning between June and September, 2021 in a garden situated at Ilorin, Nigeria. In both varieties, plants receiving 30 kg P/ha + two-stem pruning recorded highest growth indices. Marketable fruit yield was remarkably enhanced under 45 kg P/ha + four-stem pruning and 30 kg P/ha + two-stem pruning in local and Tomato 82-B respectively. Local variety showed more vigorous growth and yield than Tomato 82-B. Proximate compositions showed inconsistent results. Ascorbic acid, beta-carotene and lycopene were highest in tomato plants receiving 60 kg P/ha + four-stem pruning, 15 kg P/ha + three-stem pruning and 45 kg P/ha + four-stem respectively. Tomato 82-B had higher ascorbic acid and beta-carotene than the local variety. Conclusively, four-stem pruning + 45 kg/ha and two-stem pruning + 30 kg/ha are considered optimum for improving the yield of tomato varieties studied and that combination of pruning and phosphorus fertilization showed little influence on the fruit quality.

    Effects of priming on germination and biochemical attributes of three maize lines under NaCl stress condition
    (Bioagro, 2022) Olayinka, B. U.; Abdulkareem, K. A.; Abdulbaki, A. S.; Alsamadany, H.; Alzahrani Y.; Kareem, I.; Ayinla, A.; Kolawole, O. S.; Adam, O. I.; Odudu, F. U.; Ibuowo, M. B.; Mustapha, O. T.; Sulyman, A.
    The adverse effect of salinity has been established to vary between different varieties of the same plant species. This study was therefore conducted to determine the tolerability of three newly released lines of maize to saline conditions when primed with ethylene diamine tetraacetic acid (EDTA) and salicylic acid (SA) each at 1.0 M concentration; seeds primed with distilled water were used as control. Concentrations of 0, 50, 100, 150 and 300 mM NaCl were tested. The experiment followed a 3x3x5 factorial arrangement of treatments with three replications. The results revealed significant interaction between maize lines and salinity where the germination percentage of line SWAN-LSR-Y was much more affected than the other lines at the salinity level of 50 mM, and its speed of germination was more affected than the others when passing from 150 to 300 mM NaCl. The seedling lengths (radicle and plumule) and seed vigor index were influenced by significant interaction between the primer and salinity, where EDTA enhanced better seedling growth than the other primers when the salinity did not exceed 150 mM. OMR-LSR-SY maize line did not show tolerability at this concentration. Similarly, EDTA and SA treated maize lines showed lower accumulation of reactive oxygen species such as superoxide anion radical (O2-), hydrogen peroxide (H2O2), as well as a decrease in the malondialdehyde (MDA) contents, most importantly in SWAN-LSR-Y and BR9928-OMR-SR-Y maize lines. Catalase (CAT) and superoxide dismutase (SOD) activities were enhanced in SWAN-LSR- Y and BR9928-OMR-SR-Y upon application of EDTA.
