Ecological Influence

A survey was conducted to assess the quality of groundnut seed produced and stored under ambient environment across various agro-ecologies of The Gambia, with a view to understanding regions with comparative advantage for its production and storage. Seed production activities of 60 seed growers in 26 communities were collected using structured questionnaires, interviews and observations. The Global Positioning System (GPS) coordinates of the communities were geo-referenced to identify the geographical positioning of the production sites. Samples of the groundnut pods were taken from the seed stores, threshed and subjected to seed quality analysis. Descriptive analysis was used to categorize the seed sources, hectarage cultivated, while seed quality data were subjected to analysis of variance of Nested Design. Means of significant factors were separated using Duncan Multiple Range Test (DMRT) at 5% significant level. The study showed that groundnut seed production is better concentrated in regions with optimum and sustainable rainfall that will reduce abiotic stress during seed development like the Lower River Region, West Coast Region and Central River Region. Fleur-11 variety was identified as one of the most promising varieties for groundnut cultivation in The Gambia and Tropical Africa.

The quality of seed needs to be considered in carrot seed production to maintain its productivity. The research aims to find out the response of stecklings age and plant spacing on carrot seed quality and production. This research was held on July 2018 – April 2019 in Berastagi field trial (1340 m MSL). The experiment used Randomized Complete Block Design (RCBD) with two factors, i.e., stecklings age (2 and 3 months) and plant spacing (25, 50, 75, and 100 cm), replicated four times (32 experiment units), 10 plants from each experiment units were taken as samples. The result showed that stecklings age and plant spacing were affected to plant vegetative and generative stages. The combination of 2-month stecklings and 50 cm plant spacing increased the number of secondary umble, if compared to cultivation, which was generally used by the farmer (3-month stecklings and 25 cm plant spacing). The best quality of carrot seed was obtained from the combination of 3-month stecklings and 50 cm plant spacing.

The method of allocation of zones of seed production of agricultural plants depending on soil and climatic factors is developed on the basis of the established four types of seed yield: type I - high yield, high seed quality; type II - high yield, low seed quality; type III - low yield, high seed quality; IV - low yield, low seed quality. Data on crop types were plotted on a contour map of the studied administrative subject (region, territory, republic) with the designated boundaries of districts and soil-climatic zones, as a result, 4 possible zones of seed production were identified: 1- the zone of optimal seed production, in which the seed farms form the I type of crop; 2 - the zone of risky seed production (II type of crop); 3 - the zone of permissible seed production (III type of crop); 4 - the zone of unacceptable seed production (IV type of crop). The network of seed farms should be organized primarily in the areas of optimal seed production. When organizing the production of seed material in the zones of permissible seed production, it is necessary to increase the yield by improving agricultural technologies. In the zones of risky (II type of crop) and unacceptable (IV type of crop) seed production, it is not advisable to produce seed material.

Abstract: The inclusion of image analysis techniques for the accurate and rapid assessment of the quality of forest seeds is highly desirable. The use of digital radiographic images of seeds and the analysis of seedling images, still little used in determining the quality of forest seeds, are among the available imaging techniques. This study aimed to assess the feasibility of using the analysis of images of seeds and seedlings in the assessment of the physical and physiological quality of Senna siamea seeds. Radiographic images of seeds were obtained from five seed lots, allowing generating morphological and tissue integrity descriptors. These seeds were then subjected to germination and seedling growth tests, which allowed obtaining variables related to physiological quality. The generated seedlings were scanned and analyzed using the software ImageJ. The data were analyzed using analysis of variance, correlation, and principal component analysis. The results showed differences between seed lots in terms of physiological quality and physical integrity of internal tissues. Significant correlations were observed between the variables obtained with the radiographic analysis and seed physiological characterization tests. The use of techniques to analyze seed radiographs and seedling images allows access to information on the physical and physiological integrity of S. siamea seeds.

A study was carried out to evaluate the effect of head decapitation and planting density on plant growth, seed yield and quality of sprouting broccoli, Brassica oleracea var. italica L. using cultivar ‘Green Head’. The twenty treatments comprised of combinations of four head decapitation methods viz., D1 (decapitation of primary head at appearance and harvesting seeds from secondary heads), D2 (decapitation of primary head at marketable stage and harvesting seeds from secondary heads), D3 (removal of secondary heads at appearance and harvesting seeds primary head) and ‘D4’ (No decapitation- control) and five planting densities viz., S1 (60x60 cm), S2 (60x45 cm), S3(45x45 cm), S4 (60x30 cm), and S5 (45x30 cm). Decapitation of primary head at appearance and harvesting seeds from secondary heads (D1) and planting density S3 (45x45 cm) independently as well as in combination gave highest seed yield per plot and per hectare. This combination was also found comparable to other combinations for other characters like days to 50% flowering, days to seed harvesting, plant height at harvesting (cm), number of branches per plant, number of siliqua per plant, siliqua length (cm), number of seeds per siliqua and seed quality parameters. Therefore, it is suggested that decapitation of primary head at appearance and harvesting seeds from secondary heads (D1) in combination with plant spacing of 45x45 cm i.e. D1S3 can be recommended for commercial seed production of sprouting broccoli.

Dill seed production was investigated over two seasons, comprising a spring growing cycle (SGC) and an autumn growing cycle (AGC). The effects of growing cycle on phenological traits, yield and quality of dill seeds formed on different umbels of the mother plant were investigated. Significant differences were noted in the flowering period, seed yield and quality parameters. The SGC resulted in a shorter time from sowing to bolting and flowering initiation compared with the AGC. Plant height, number of umbels/plant, number of umbelets/umbel, umbel diameter, umbel length and seed weight/plant increased in the AGC. In contrast, decreased germination at 20/30°C and at 13°C, and increased mean germination time at 20/30°C in AGC indicated lower seed quality compared with SGC. Primary umbels produced the best yield and higher quality seeds, followed by the secondary umbels while tertiary umbels gave poor yield and quality seeds in both SGC and AGC. In conclusion, AGC was advisable for higher seed yield, but SGC resulted in higher seed quality compared with the AGC. This highlights the need to select a suitable growing cycle to guarantee high seed yield and quality for each seed production environment.

Introduction In 2011, member states of the World Health Organization (WHO) Africa Regional Office (AFRO) resolved to eliminate Measles by 2020. Our study aims to assess The Gambia’s progress towards the set AFRO measles elimination target and highlight surveillance and immunisation gaps to better inform future measles prevention strategies. Material and methods A retrospective review of measles surveillance data for the period 2011–2019, was extracted from The Gambia case-based measles surveillance database. WHO—UNICEF national coverage estimates were used for estimating national level MCV coverage. Measles post campaign coverage survey coverage estimates were used to estimate national measles campaign coverage. Results One hundred and twenty-five of the 863 reported suspected cases were laboratory confirmed as measles cases. More than half (53.6%) of the confirmed cases have unknown vaccination status, 24% of cases were vaccinated, 52.8% of cases occurred among males, and 72.8% cases were among urban residents. The incidence of measles cases per million population was lowest (0) in 2011–2012 and highest in 2015 and 2016 (31 and 23 respectively). The indicator for surveillance sensitivity was met in all years except in 2016 and 2019. Children aged 5–9 years (Incidence Rate Ratio—IRR = 0.6) and residents of Central River region (IRR = 0.21) had lower measles risk whilst unvaccinated (Adjusted IRR = 5.95) and those with unknown vaccination status (IRR 2.21) had higher measles risk. Vaccine effectiveness was 89.5%. Conclusion The Gambia’s quest to attain measles elimination status by 2020 has registered significant success but it is unlikely that all target indicators will be met. Vaccination has been very effective in preventing cases. There is variation in measles risk by health region, and it will be important to take it into account when designing prevention and control strategies. The quality of case investigations should be improved to enhance the quality of surveillance for decision making.

Fruit and seed productive capacity and physiological seed quality of 2 varieties of husk tomato were estimated: Jojutla and CHF1. The study was conducted in hydroponics under greenhouse, in the CUCBA-UDG, Zapopan, Jalisco. Red volcanic rock (/Tezontle) of 0.5 to 2 cm in diameter was used in 19 L polyethylene bags and Steiner's universal nutrient solution of 0.3 to 0.7 atm, depending on the stage of the plant. The production of fruit and seed and the physiological quality of the seed were estimated. The varieties Jojutla and CHF1 showed a similar behavior in the production of fruit and seed, with lower fruit yields than expected (30 ton / ha in the field) because only 3 harvests were made, looking to produce husk tomato in winter when it reaches attractive prices. The weight of the fruit was greater as cuts were made while the seed production improved by cutting, associated with a greater number of fruits, while the weight of the fruit was not related to the seed yield. The physiological quality of the seed was affected by cutting the fruit to commercial maturity even when it was left to mature in the shade.
