Edmond Ahipo Due | Koffi Djary Michel | Yolande Dogore Digbeu
In Sub-Saharan Africa, especially, in Côte d’Ivoire, the wild edible mushroom Termitomyces heimii Natarajan is the most prized and widely consumed for different reasons such as taste, flavour, attractiveness, uses as substitutes for meat or fish and medicinal values. The present study was aimed at evaluating the proximate composition and functional properties of T. heimii flour for further food products formulation. Fresh mushroom T. heimii were obtained from the market of Aboisso (5° 28′ 06″ N and3° 12′ 25″ W) in Côte d’Ivoire. The fresh mushrooms were dried and ground to obtain the crude flour. Chemical composition and functional properties were investigated using standard methods. The chemical composition revealed that it contains crude protein about 23.75%, crude fat 3.58%, moisture 11.59 %, ash 7.40%, total carbohydrate 54.70% and energy value of 345.90 kcal/ 100 g. These results suggest that T. heimii can be used in human diet to prevent undernourishment due to protein. Furthermore, the low fat content suggest that it would be an ideal food for obese persons and useful in preventing hypertension and hypercholesterolemia. The functional properties showed that it has high bulk density and water absorption capacity with values of 0.737 g/mL and 315.15 ± 45.74% respectively. This flour exhibited also good foaming properties. All these characteristics make it suitable as good thickeners in food products, useful in foods such as bakery products which require hydration and attractive for products like cakes or whipping topping where foaming is important. The mushroom T. heimii could be utilized for making some low-fat foodstuffs and snacks with considerable protein content. The mushroom flour shows good functional characteristics for use in many food industries.

In this study, five different set type yogurt with vegetable purees, namely as control (K), yogurt with pumpkin (YBK), yogurt with carrot (YHA), yogurt with green peas (YBE) and yogurt with zucchini (YYK) were produced. The viable cell counts of S. thermophilus and L. delbrueckii subsp. bulgaricus were increased as a result of the ability of dietary fiber to stimulate their growth which is present in yogurt as puree. Vegetable puree addition had a noticeable effect on pH, titratable acidity, whey separation, sensory properties as well as textural attributes such as firmness, cohesiveness, consistency and viscosity index in yogurt. The highest viscosity index, consistency and firmness were observed in yogurt with the carrot puree, while the samples with zucchini presented the less compact structure and textural properties. As a result the present work showed that all the vegetable puree used had a beneficial role to improve textural properties of set type non-fat yogurt and could be used for the development of dairy products with functional ingredients.

Deficiency of sulphur (S) is an important limiting factor of plant growth for sustainable agricultural production. The decline in sulphur dioxide emission, decrease in S-containing fertilizer consumption due to the high cost of S-fertilizers, breeding of new high yielding species are the well known causes of S-deficiency. A greenhouse experiment was conducted to investigate the effects of several doses of K2SO4-S, CaSO4-S and elemental-S applied on growth, shoot dry matter yield, S and N concentrations of wheat cultivar. The experiments were conducted in three soils differed from available S concentrations. Effects of different S-treatments (0, 25, 50 and 100 mg S kg-1) and S-forms had significant effects on shoot dry matter yields of plants. Sulphur from different S-sources did not increase shoot S-concentrations in Eskisehir and Konya soils, but increase was significant obtained in the Harran soil. Shoot S-concentration in Harran soil for zero K2SO4 treatment was 0.09%, the values were 0.22, 0.26 and 0.27% respectively for 25, 50 and 100 mg kg-1 treatments. The results indicated significant effects of S-treatments on plant growth and yield mostly based on soil properties, especially the available S-levels

This study examines the impact of New Integrated Management Package (IMP) adoption on income and poverty among fodder farming household in Sahl El-Tina. The IMP such as Rate, time, and methods of nitrogen fertilization and other fertilization, Leaching requirements for some crops, Intercropping system, Use of suitable crop genotype/variety, Use of modern irrigation systems or modified systems to save water, date, rate and method of planting. The study aims mainly to improve the lives of small farmers through the level of dissemination and application of cultivation techniques forage crops tolerant to salinity through develop and disseminate technologies packages of forage production. And reducing their probability of falling below the poverty line. Therefore suggest that intensification of the investment on IMP dissemination is a reasonable policy instrument to raise incomes and reduce poverty among fodder farming household. It used instrumental variables (IV)-based estimator to estimate the Local Average Treatment Effect (LATE) of adoption of IMP on income and poverty reduction, using cross-sectional data of 200 farmers from Shal El-Tina. The findings reveal a robust positive and significant impact of IMP adoption on farm household income and welfare measured by per capita expenditure and poverty reduction. Specifically, the empirical results suggest that adoption of IMP raises household per capita expenditure and income by an average of 529.27$ and 1371$ in Shal El-Tina per cropping season respectively, thereby reducing their probability of falling below the poverty line. Therefore suggest that intensification of the investment on IMP dissemination is a reasonable policy instrument to raise incomes and reduce poverty among fodder farming household, although complementary measures are also needed. The incidence of poverty was higher among non-IMP adopters (55.2%) than IMP adopters (49.5%). In addition, both the depth and severity of poverty were also higher (20.85% and 15.42%) among non-adopters than the adopters (18.48% and 9.88%). All three poverty measures indicate that poverty was more prevalent and severe among non-adopters compared to adopters.

Shreef Mahmood | Md. Nazmul Hasan | S.M. Younus Ali | Rafija Alam Ripa | Md. Golap Hossain
Two plant growth regulators: β-NOA (50 and 80 ppm) and GA (200 and 250 ppm) were applied to emasculated flowers at anthesis to set parthenocarpic fruit, while in the control treatment fruit set was achieved by natural pollination. The application of β-NOA found ineffective in setting parthenocarpic guava. No significant differences were observed in the length and diameter of fruit between parthenocarpic and naturally pollinated seeded fruit at different days after anthesis. The mean fruit weight, TSS and ascorbic acid content of parthenocarpic fruit were similar to that of seeded fruit. Significant higher amount of total polyphenol was detected in the seeded fruit than the parthenocarpic fruit. Although 200 ppm GA showed comparatively better response to fruit growth, TSS and ascorbic acid content than 250 ppm GA but not in a statistical level.

The aim of this study was investigate the effects of whole wheat scattered the litter on performance, carcass characteristics and viscosity and pH of excreta in male broilers. A total 336 male chicks (Ross-308) were randomly distributed into two dietary treatments of four replicates each. Same starter (0 to 21 d) and finisher diets (22 to 45 d) were used in both groups. All birds were given ad libitum access to feed and water throughout experimental period. From 8 to 21 days, whole wheat (10 g/bird/day) was randomly thrown on the litter in one of the experimental groups twice a day (at 0800 and 1200 h). Scattering whole wheat in the litter decreased body weight of male broilers at 21 d of age while increased at 45 d of age. Feed intake was not affected by whole wheat scatter treatment. From 22 to 45 and 0 to 45 d of age, feed conversion ratio significantly improved in group scattered whole wheat in the litter than control group. No significant differences were occurred among groups for mortality, carcass characteristics and excreta viscosity. However, pH value of excreta in group scattered whole wheat the litter showed significant reduction as compared control group. According to these results, scattering whole wheat the litter at an early stage affected the performance of male broilers positively.
