Comparison of linear discriminant analysis, support vector machine and artificial neural network in classifying Nigerian local turkeys based on plumage colours using biometric traits
(2022-10-18)
The ability of linear discriminant analysis (LDA), support vector machine (SVM), and artificial neural network (ANN) models to differentiate biometric traits of Nigerian local turkeys was investigated in this study. The biometric traits (bodyweight, body length, breast girth, thigh length, shank length, keel length, wing length, and wingspan) in 200 (20-week-old) turkeys were measured. Seventy percent of the datasets were used to train the three models, with the remaining 30% being used to test their performance. All ...

Use of corncob biochar and urea for pakchoi (Brassica rapa L.) cultivation: Short-term impact of pyrolysis temperature and fertiliser dose on plant growth and yield
(2022-10-18)
This study aimed to evaluate the effect of pyrolysis temperature of corncob biochar as a soil amendment and urea fertiliser on the growth and yield of pakchoi. Pakchoi was cultivated in pots
(13 cm height, 19 cm upper diameter, and 13.5 cm bottom diameter). Two factors including pyrolysis temperature of biochar and urea dose were combined with four levels each. Pyrolysis temperature factor consisted of B0 (no biochar), B1 (250 °C), B2 (300 °C), and B3 (350 °C). Urea dose consisted of F0 (no urea), F1 (0.6 g pot-¹), ...

Agripreneurial drive among women shea butter processors in Kwara State, Nigeria: the motivating factors and efficiency
(2022-10-12)
This study examined agricultural entrepreneurship among women shea butter processors in Kwara State Nigeria. It assessed their motivation factors, level of efficiencies, determinants of output and challenges faced in the entrepreneurial drive by the women. Primary data, collected using a semi-structured questionnaire, were collected from randomly selected 120 shea butter women processors. The data obtained were analysed with descriptive statistics, index ranking and the stochastic frontier function. The results showed ...

Effect of Village Savings and Loan Associations on adoption of index-based crop insurance under limited liabilities
(2020-03-26)
A household survey and focus group discussions were conducted to quantify the general determinants of an index-based crop insurance adoption under limited liabilities in Burundi, and specifically the effect of existing Village Savings and Loan Associations (VSLAs). The survey sample comprised of 40 crop insurance adopters, 40 non-adopters and 40 drop-outs in Bukirasazi and Makebuko communes of Gitega province.
The results indicated that saving money (by VSLAs) for upcoming premium payments and regularly VSLA meetings ...

Taste masking in vegan food processing with natural substitutes
(2022-12-29)
Climate change, sustainability issues, increased risks of meat diet on both ecology and human health cause changes in the eating habits of individuals. Plant-based foods supply protein sources with health-promoting compounds. The bitterness of plant-based foods is a challenge for both food manufacturers and consumers. So far, artificial taste blockers, salt, sugar, and fat have been applied to mask the bitterness of plant-based products. However, people are conscious of "clean labelling " and "natural " ingredients ...

The potential of cabbage waste extract as a bio-stimulant for enhancing growth, biochemical constituents, and oil quality of thyme (Thymus vulgaris)
(2022-12-29)
Thyme (Thymus vulgaris L.) is an important cultural aromatic plant, whose herb and essential oils (EOs) have been used in many industrial and medicinal applications. Herb and EO yields are often negatively influenced by various factors, so it is important to keep finding new growing procedures that increase the quantitative content of herbs and EOs. Therefore, this paper is focused on the effects of applying cabbage extract (CE) at different concentrations on morphological parameters, mineral contents, total ...

Physiological response of some canola genotypes to proline concentration under saltwater irrigation conditions
(2022-12-29)
A pot experiment was conducted in split-split plot design with four replications to study proline foliar application with 0, 50, and 100 ppm and four canola genotypes cultivated under irrigation of tap water and salinity irrigation water at 4500 ppm and their interactive effects on growth characters, yield, and yield components and some chemical composition of the canola plants. Results indicated that a higher salinity level at 4500 ppm reduced growth, photosynthetic pigments, yield, and yield attributes as well as ...

The effects of weather factors on titrating acids accumulation in sweet cherry fruits
(2022-12-29)
During the fruit formation, the weather conditions have a decisive influence on the organic acids accumulation. In the context of global climate change, this issue has become new. The study of the titrated acids content in sweet cherry fruits was carried out for 12 years. Cherry fruits of three ripening groups were selected for the study. The average and strong correlation dependence between 11 weather factors and the titrated acids content for the sweet cherries varieties of early, middle, late ripening periods were ...

Characterisation of the lactation curve of Gyr and Sardo Negro cattle
(2023-07)
The objectives were to characterize the lactation curves (LC) of tropical Gyr and Sardo Negro (SN) cattle from Mexico for the design of breeding and management programs for these breeds. A total of 3561 records of 504 lactations and 3927 records of 449 lactations were used for Gyr and SN, respectively. Three lactation lengths (LL) were evaluated, namely 240 (240d), 270 (270d), and 300 (300d) days, with five non-linear models (NLM): Wood, Wiltmink, Cobby, Brody, and Sikka. Milk production was obtained at the beginning ...

Pyrolytic transformation of indigenous biomass wastes into biochar: an insight into char structure and physicochemical characteristics
(2022-08-20)
Biochar, the product obtained by the pyrolysis of organic materials with little or no available air, acts as a longterm recalcitrant source of organic carbon when applied to soil. In the present study an in-farm method has been standardized for the pyrolytic conversion of four indigenous biomass resources into biochar. The biomass feedstocks viz. bovine bone (BB), coconut shell (CS), rubberwood (RW) and water hyacinth (WH) were dried and subjected to proximate, ultimate, biochemical analysis and were subjected to ...
