This study aims to investigate the effect of incorporating Moringa oleifera leaf powder and sardine powder into wheat-based noodle formulations on their nutritional composition. Different formulations were prepared with varying ratios, expressed in percentage (%): WM1 (99.6 wheat: 0.4 moringa ), WM2 (99.2 wheat: 0.8 moringa) andWM3 (99 wheat :1 moringa ); WS1 (95 wheat: 5 sardine ), WS2 (90 wheat: 10 sardine ), WS3 (85 wheat: 15 sardine) and the control sample (WC) containing 100% wheat was also included for comparison. The nutritional parameters assessed included crude protein, crude fiber, crude fat, ash, carbohydrate and energy content. Mineral compositions were also determined, including calcium (Ca), magnesium (Mg), iron (Fe) and zinc (Zn). The results demonstrated significant variations in the nutritional composition of the different formulations compared to the control sample. Results of proximate composition based on dry matter showed that the crude protein values ranged from 11.76-21.40g/100g, crude fibre values ranged from 0.00-0.02g/100g, crude fat values ranged from 1.89-2.94g/100g, ash content values ranged from 1.38-2.26g/100g, carbohydrate content values ranged from 62.31-74.29g/100g and energy values ranged from 358.50-364.53 kcal/100g. Furthermore, the minerals results showed iron values ranged from 32.55-65.50mg/100g, calcium values ranged from 7.39-66.61g/100g, magnesium values ranged from 28.86-87.35mg/100g and zinc values ranged from 2.21-39.25mg/100g. These results indicate that the fortification of noodles with moringa and sardine powders can be a viable approach for enhancing the nutritional value of the final product.

The experiment aimed to evaluate the effect of organic manure on the growth and yield of carrots (Daucus carota L.) grown in Jos and Makurdi Benue State, Nigeria. The treatments used were organic manure sources (Poultry dropping (20t/ha), Cow dung (20t/ha), Goat manure (20t/ha), dung site (20t/ha) and control (zero application and) the spacing used between plants and rows were 15 and 75cm, respectively. The experiment was laid in a randomized complete block design with three replications. During the investigation, some physiological variables, such as plant height and the number of leaves were measured. Other characteristics like aerial weight, root weight, root length, rot diameter, harvest index and over-all yield were also recorded. The results of the investigation revealed that carrot responded to nutrient sources with poultry dropping and Jos producing better in both growth and yield parameters. All the parameters studied significantly (P ≤ 0.05) responded to nutrient source with poultry dropping been superior in both growth and yield-related characters such as plant height at 8WAT (32.20), the number of leaves 8WAT(122.20), aerial weight (10.27g), root weight (18.02g), root length(12.81cm), root diameter (4.00mm), harvest index (0.71) and over-all yield (5.10t/ha). Carrot grown in Jos outgrows those cultivated in Makurdi in both growth and yield-related character. Based on the results obtained it could be suggested that the use of poultry dropping which is better in both growth and yield characteristics will lead to optimum yield in carrot cultivation in the study areas.

Sesame is one of the major crops produced in Yobe State, Nigeria. However, its production is influenced by some socioeconomic factors. The socio-economic determinants of sesame (Sesame indicum L) production among farmers in Bade LGA, Yobe State, Nigeria were investigated. Primary data were collected with the use of a structured questionnaire from 180 respondents selected using two-stage sampling technique. Data were analyzed with descriptive statistics and multiple regression analysis. Findings show that sesame farmers between the age of 20-39 years old dominated sesame production (57.22%) in the study area. About 61.11% of the respondents were male while 38.89% female were involved in the sesame production in the study area. Age, sex and marital status had a positive and significant influence on sesame production in the study area. The major constraints to sesame production were poor access roads, high cost of input and insecurity. The findings suggest that improved sesame production could be achieved by giving consideration to some significant variables identified; farmer’s cooperative should be initiated to offer opportunities to members to have access to capital/credit and other inputs. Government should make policies that will facilitate farmers’ access to education and training. Also, consideration should also be given to rural infrastructure and inputs subsidies not limited to fertilizer as these were among the notable constraints faced by farmers. Government should look into the inherent potential of sesame business as that will increase foreign earnings and local industries for processing sesame into industrial usage.

Tomatoes and their derivatives contain bioactive compounds such as phenolic compounds, carotenoids and vitamins which positively contribute to human health. This study aimed to evaluate the bioaccessibility and biotransformation of phenolic compounds in a tomato pulp using static in vitro model of digestion and an in vitro colonic fermentation. The in vitro digestion of the concentrated tomato pulp (CTP) enhanced total phenolic compounds content, while colonic fermentation decreased the bioaccessibility of phenolic compounds over 72 hours of fermentation. Tomato pulp increased propionic, butyric and valeric acids production compared to control and also ammonium ions production. Lactobacillus and Bifidobacterium remained present after 48 h and, although a significant reduction (p < 0.05) in total coliforms and E. coli counts in the presence of tomato pulp was also observed, Clostridium was the predominant microorganism during colonic fermentation.

Assessing and understanding the variations existing in crops due to genetic composition and environmental variability is very important in order to exploit the genetic constitution of crop plants. To this aim, variability measures such as phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) are commonly used. Heritability and genetic advance are major concerns for common bean to identify important traits for common bean genetic improvement. The field experiment was conducted at Mandura and Dibatie research substations working with sixteen genotypes of the common bean during 2017/2018 in lattice design with three replications to evaluate the performance of common bean genotypes and estimate the genetic variability. Heritability and genetic advance were estimated in relation to yield and its component traits for future breeding programs. Combined analysis of variance across locations revealed highly significant variations among genotypes for all traits under study. The PCV ranged from 3.36% for days to flowering to 15.91% for a number of pods per plant while the GCV value ranged from 0.75% for days to flowering to 13.74% for the number of pods per plant. Broad sense heritability values ranged from 5.00% for days to flowering to 84.61% for a hundred seed weight. Generally, the result of the study showed that significant genetic variability among tested genotypes and a simple selection for effective improvement of these traits.

The edible seeds of bottle gourd [Lagenaria siceraria (Molina) Standl.] are rich in oils, proteins and minerals of high nutritional quality. They are highly prized in pan tropical regions where they constitute valuable resources for food and nutrition security. In this study, near-infrared hyperspectral imaging (NIR-HSI) was combined with chemometrics to assess the variability of seed chemical content of African cultivars for the selection of nutritional traits. Six hundred seeds of four accessions belonging to two cultivars were collected from the Ivory Coast (West Africa) and analysed. The NIR-HSI spectra collected on whole seeds in the 1100-2400 nm range revealed that the main absorption bands of the seed chemical content were associated with water, lipids and proteins. The absorbance values between seeds of the same accession in these spectral regions varied up to 1.8 folds. Among the two chemometric tools used, principal component analysis (PCA) did not separate the accessions while Partial Least Squares Discriminant Analysis (PLS-DA) discriminated the accessions with 87.33 % to 94.67 %, and the cultivars with 90 % to 92 % correct classification. Seed oils from bottle gourd are for instance rich in linoleic acid which is an essential fatty acid for human health. The non-destructive and qualitative determination of the content of single seeds was demonstrated in the study and provides the opportunity to select superior seeds for the improvement of key nutritional traits in bottle gourd.

The study assesses the impact of IFAD-VCDP on rice yield and farmers’ income, as well as constraints to IFAD-VCDP implementation in the study area. A purposive sampling method was adopted to select 220 rice farmers. Primary and secondary data were used. Questionnaires were used to collect information from the beneficiaries of the programme. The respondents verified the claims of the programme with respect to the provisions of farm inputs, extension service and basic infrastructures. A paired-samples t-test was used to analyze the data. The findings of the study revealed that 55% of the respondents have yields between 1–10 bags (100kg) and after the intervention, 52% of the respondents had yield of 61–80 bags (100kg). Similarly, 43% of the respondents have income between N51,000-N70,000 before the intervention programme and after the intervention, 52% of the respondents have income between N141,000-N170,000 and 42% have between N171,000-N200,000. This shows significant positive impacts on crop yield and income. The results of the paired-sample t-test show that there is difference in the mean income of rice farmers before IFAD-VCDP intervention (M = 2.54, SD = .81) and after IFAD-VCDP intervention (M = 4.35, SD = .59) at the .05 level of significance (t = 27.25, df = 219, n = 220, p< .05, 95% CI for mean difference 1.68 to 1.94). Given the positive impact of the IFAD-value chain development programme on rice farming in the study area, there is a need to extend it to other rice-producing LGA in Taraba State. Keywords: Ardo Kola, IFAD, Rice farming, Smallholder farmers and VCDP.

The results of the paired-sample t-test show that there is difference in the mean income of rice farmers before IFAD-VCDP intervention (M = 2.54, SD = .81) and after IFAD-VCDP intervention (M = 4.35, SD = .59) at the .05 level of significance (t = 27.25, df = 219, n = 220, p< .05, 95% CI for mean difference 1.68 to 1.94). Given the positive impact of the IFAD-value chain development programme on rice farming in the study area, there is a need to extend it to other rice-producing LGA in Taraba State.

The study explored to find out the possible strategy for the processing of sapota into its value-added shelf-stable products. Therefore, an attempt was made to develop marmalade with different concentrations of orange peel viz. 0 %, 5 %, 10 %, 15 % and 20 % respectively. Sensory evaluation, proximate and nutritional composition was performed on the day of preparation and after storage. Marmalade treated with orange peel and without orange peel was rich source of proximate and nutritional composition. The final TSS of the developed marmalade maintained 65.30±02°B. ß-carotene (12.21±0.01 and 11.93±0.03 µg/100 g), pH (5.05±0.04 and 4.90±0.01), total sugar (21.15±0.04 % and 22.28±0.03 %) and reducing sugar (9.70±0.01 % and 10.15±0.05 %) was superior on the day of storage and after storage in without orange peel treated marmalade (T1). On the day of storage and after storage, the highest total carotenoid and vitamin-C content of the orange peel treated marmalade ranged from 31.92±0.02 to 49.21±0.51 mg/100 g and 23.26±0.02 to 43.39±0.05 mg/100 g, 4.68±0.02 to 5.84±0.03 mg/100 g and 2.36±0.01 to 3.62±0.06 mg/100 g respectively. According to the expert panelist, the highest overall acceptability score was secured by the combination of T2 followed by others in terms of color, aroma, mouth feel and high spreadable capacity. The marketable life of the developed marmalade could be extended 6 months more without any excessive-quality deterioration. This technology could be utilized to fulfill the off-season nutritional requirement and increase the income of the farmers to enhance their productivity. Keywords: Sapota fruit, vitamin-C content, total carotenoid content, ß-carotene content, marketable life, sensory evaluation.

A screen house pot study using bio-slurry at the rate of 7.8 t N / ha was conducted at Makerere University Agricultural Research Institute (MAURIK) Kabanyolo, Uganda. This was monitored using fecal indicator organisms (coliforms, Escherichia coli and Enterococci) in loamy sand, sandy loam and sandy clay loam texture obtained at the study site within 5litres pots under a Complete Randomized Design under a screenhouse. The different textures significantly (p<0.05) reduced the fecal indicator organisms. Conditions within the loamy sand texture reduced the pathogenic microorganisms within 90 days due to its high sand content. In this soil texture, E. coli and enterococci were reduced to undetectable levels within 90 days unlike the coliforms. Fecal, Bio slurry, coliforms, Escherichia. coli, Enterococci
