This study was carried out in greenhouse on strawberries grown in a column m in Uzundere district, Erzurum, Turkey. The biostimulator 'Macrocrop' and 'Gold'ne' were foliar-applied to the cv. Fem at the rates of 250, 500 and 750 ppm l, 2, 4 8 times at 15 days intervals beginning 15 days after planting. Two months after last application, the content of N, P, K, Ca, Mg, Fe, Cu and Zn in the leaves was analyzed. According to the results, there were significant differences between the treatments. The nutrient composition was higher in the plants treated with the biostimulators than in the control. Nitrogen (N) content was 2.48% in the control whereas in plants treated 4 times with 250 ppm it was 3.40% and those treated once with 250 of Goldmarine had 3.06% of nitrogen. In all rates of biostimulator, there was a gative relationship between application frequency and N content. Ca1cium (Ca)content63% in the control plants whereas the plants that received Macrocrop at the rate of 750 ppm and those to which Goldmarine was applied once at the rateof 750 ppm had 2.38%. Similarly, iron (Fe) content was 213 ppm in the control whereas in the plants that received Goldmarine four times at the rate of 500 ppm and in those with Macrocorp four times at the rate 500 ppm, it was 1120 ppm.
This study evaluated the phytochemical and nutrient composition of four selected vegetables consumed in Nigeria, namely, bush mallow (ahihara), garden egg leaf (okpokwa), African spinach (inine), and bush okro (ewedu). They were analyzed for proximate, minerals, vitamins and phytochemical contents. Proximate values maintained the following ranges: moisture 6.73% to 91.22%, protein 7.05% to 32.12%, crude fiber 2.75% to 6.36%, ether extract 3.15% to 6.81%, ash content 2.81% to 6.81% and carbohydrate 48.75% to 72.62%, while energy value ranged from 340.54kcal to 363.07kcal. The vitamin content for these vegetables ranged as follows: vitamin A 0.13.mg/100g to 370.64mg/100g, thiamin (vit B₁) 3.12mg/100g to 7.45mg/100g, riboflavin (vit B₂) 0.08mg/100g to 3.96mg/100g, vitamin B₃ (niacin) 0.17mg/100g to 1.91mg/100g, and vitamin C 39.84mg/100g to 98.75mg/100g. The mineral content, namely, calcium ranged from 45.61mg/100g to 430.69mg/100g, magnesium 11.05mg/100g to 198.14mg/100g, potassium 49.82mg/100g to 708.28mg/100g, sodium 2.36mg/100g to 22.98mg/100g. Also the phytochemical content of the vegetables for phytate ranged from 0.47mg/100g to 3.04 mg/100g, tannin from 0.10 mg/100g to 1.01 mg/100g, saponin from 0.16 mg/100g to 2.56 mg/100g and oxalate from 0.63 mg/100g to 0.72 mg/100g. Result obtained from these vegetables show that they can contribute qualitatively to the nutritional need of the Nigerian population, especially among the rural dweller where vegetables are major food source.
In summary, the nutrient requirements of the premature infant are not well defined, but the CPS Nutrition Committee has provided a systemic framework for describing recommended nutrient intakes. These current recommended intakes appear to provide safe quantities of nutrients that support intrauterine growth rates. Still uncertain, however, is the extent to which the recommended intakes lead to the provision of energy and nutrients in quantity and composition in amounts that allow the premature infant to achieve all aspects of normal in utero development, especially that of the nervous system.
The nutrient composition of some neglected and less familiar plant seeds was studied. The seeds showed wide variation in constituents and could be compared with commonly consumed food articles. The protein content ranged írom 29.2 g /kg in Callitris intratropica to 253.5 g/kg in Percopsis elata, while the carbohydrate content was found to be between 330.5 g/kg and 734.8 g/kg in P. elata and Dracena mannii, respectively. The highest fat and fibre content of 215 g/kg and 290.5 g/kg occurred in P. elata and C. intratropica, respectively. P. elata, D. mannii and C. intratropica promises a good source of protein, carbohydrate and fibre, respectively. The legumes showed high ash content but most seeds were rich in Mg, K and F and defficient in Na and Cu. Investigation of the antin utrients and possible toxic effects of the seeds is necessary before their full utilisation.
