    A laboratory study was carried out to evaluate the effect of leaf aqueous ex- tract of Jatropha curcas L. on germination and early shoot growth of four pepper (Capsicum) species at the Department of Plant Science and Biotech- nology Laboratory, Nasarawa State University, Keffi, Nigeria. Data collected were percentage inhibition and shoot length. Results from the experiment in- dicated that there was significant difference between the treatments (4%, 8%, 12%, 16% and 20%) and the control (0%) and within the treatments at P ≤ 0.05. All the test crops were affected by different concentrations of the aque- ous extracts and the most pronounced effect was at 12%, 16% and 20% con- centrations of the extracts in all cases respectively. Germination, shooting were inhibited completely at higher concentrations in the cases when com- pared with the control. The inhibitory effect was found to be concentration dependent and may be due to the presence of water soluble allelochemicals like phenols, tannins and azeliac acid.

    The chemical constituents present in plants have been reported to vary with the geographical location of the plants. This investigation assessed the nutritional composition of some selected date fruits from the experimental gene pool in dutse, Nigeria in order to investigate any uniqueness relative to Date palms cultivated in other regions. The proximate analysis of the date fruits were quantitatively analyzed for carbohydrates, protein, lipids, fiber, moisture, sucrose, glucose and fructose. The mineral contents were analyzed using atomic absorption spectrophotometer (AAS). The highest moisture content were recorded for accession R13P5 (7.65±0.03). Moreover, carbohydrate and protein content was found to be highest in accessions R5P24 (64.55±5.73) and R4P29 (7.13±0.19) respectively. Similarly the ash, fiber and lipid contents were highest in accessions R5P8, R14P21 and R5P24 respectively. Considerable amounts of sucrose, glucose and fructose were recorded in all the accessions. The mineral contents analyzed indicated good sources of minerals such as calcium, magnesium, sodium, potassium and phosphorus. The present finding helps in understanding the nutritional status of different accessions in some Nigerian date palm fruits which can serve as a baseline for selection in improvement of the crop for the nutritional health benefits.
