Smallholder farmers face challenges when they lack information on their agricultural activities. To address this, we suggest a web-based system that can be used by farmers to help them in decision making considering the fact that all necessary information is provided by the system. Farmers can input crop type they want to grow and area. This data will help to recommend them the best crops that are suitable to be grown in that area and the necessary growing practices that can be done to produce high yield and have maximum profits, considering the average rainfall of that year. A persistent issue we face in Zimbabwe is the lack of access to reliable agricultural data. In the agricultural sector, one major uncertainty for farmers is the outlook of their future harvest. Once their produce is ready for sale, the presence of other potential buyers compels traders to offer prices that align closely with those in the formal market. However, without timely information, traders can take advantage of the situation by purchasing crops at unfairly low rates. Having data that tracks prices across various markets in near real-time would enable farmers to have a precise and complete understanding of their selling choices to maximize their profits.Full article

The study aimed to assess the impact of off-season vegetable farming on farmers in the Savelugu Municipality in the Northern Region. The study population consisted of all respondents to off-season vegetable farming in the Savelugu Municipality in the five selected communities in the Northern Region. A purposive sampling technique was used for a sample size of fifty (50) off-season farmers in the selected communities. An interview guide and questionnaire were used to solicit data to conclude the findings. The data derived from the questionnaire were analysed in a step-by-step thematic analysis that included reading the transcriptions several times, coding, generating codes, and reviewing and naming themes. Afterwards, the questionnaire and interview guide responses were transferred into Microsoft Excel under assigned variable names. Descriptive statistics, namely frequency, means, and percentages, were used to analyse the data. Off-season vegetable production technology can be gained by using different agro-climatic regions, maintaining or adjusting planting time, selecting varieties, and creating artificial and controlled environments through tunnels, polytene houses, glass houses, hotbeds, etc. Moreover, Off-Season vegetables helped earn income and ranked highest with an overall mean score of 1. Nearly all the trained farmers said their primary constraint was the high incidence of pests and diseases. It is evident that off-season cultivation is profitable and significantly impacts the farmers' consumption expenditure and food security status. Therefore, providing improved and modern agricultural inputs to off-season farmers is essential for rural agricultural development.Full article

Quantitatively, this study aimed to determine the abundance and diversity of the insect fauna that visits the staminate and pistillate flowers of Cocos nucifera. The study was conducted at an experimental plantation belonging to the Coconut Research Programme (CRP) of the Oil Palm Research Institute (OPRI) of the Council for Scientific and Industrial Research (CSIR), to provide diagnostic support for the Cape St. Paul Wilt Disease (CSPWD) at Asebu in the Central Region of Ghana. The populations of coconut palms represented the dwarf type with few tall ecotypes. Five Insects were randomly chosen with newly opened inflorescences. Observations and collections of insect visitors to coconut flowers were made once a week on 30 newly opened inflorescences, five from each batch within the plantation. Specimens of the data were deposited in the official insect collection and processed at the laboratory of the Entomology Museum of the Department of Conservation Biology and Entomology, University of Cape Coast, Ghana. The study indicated that 9 different species of insects were identified to be the true fauna that visited the staminate and pistillate flowers of C. nucifera Ethiosciapus sp., Sarcophaga sp., Scolia dubia, Lucilia sp., Ornidia sp., Apis melifera, Dactylurina standingeri, Red Ant and Black Ant. These insects were observed in all the six batches considered and were available at all times of the day. Most of the insects were observed in the early morning from 6 am - 9 am followed by the evening 4 pm –7 pm. The abundance of insect visitors was low during the mid-day (11 a.m. to 3 p.m.) in all six batches during high temperatures. The results of this study revealed that there were abundances of Ethioscipus sp. was the least abundant in all the batches followed by Scolia dubia then Sarcophaga sp. Red Ants had the highest abundance in most of the Batches thus becoming the most abundant insect that forage the coconut inflorescence at the Asebu plantation. The bees, Apis melifera and Dactylurina standingeri were the most abundant species after the Red Ants. All these groups of insects were not considered in the study and it is recommended that further studies consider such visitors to observe which insects are doing what on the inflorescence. The range for the ‘time of day for’ of the study was mostly diurnal (morning 6 am-9 am, afternoon 11 am-2 pm and evening 4 pm7 pm). There was no observation made of the pollination system or activities of these insect visitors nocturnally. There may be high pollination activities of these insects during the late evenings. It is recommended that future work should incorporate the late evening period to observe an abundance of diurnal insect visitors of the coconut inflorescences.Keywords: Insect, Fauna, Staminate, Pistillate Flowers, Cocos nuciferaFull article

This experimental study was carried out to evaluate the effect of three selected pollinator-friendly practices on the African eggplant (Solanum aethiopicum) at Mankessim in the Central region of Ghana. The study focused on determining how the practices affect the production and yield of garden eggs. The three pollinator-friendly practices were the use of mulch, cassava hedgerow/marigold plants and controlled pesticide application in garden egg farms. Experimental-control group design was used. Mulching positively influenced the number of flowers, fruits and height of garden eggplants. Cassava hedgerow/marigold plants influenced the number of flowers, but had no significant effect on the number of fruits and plants’ height. There was no effect on the number of flowers, fruits, and height of garden eggplants when pesticide application was controlled or uncontrolled. No significant influence was observed in fruit weight in all treatment and control plots. The growth and yield trends observed in this research indicated that practicing the three pollinator-friendly practices may encourage flower visitors leading to effective pollination and increased yields. It is recommended that mulching be practised in garden egg farming to increase the growth and productivity of garden eggplants.Full article

The government of Mexico City carried out the introduction of palm trees in the 50s to increase the visual appearance of the main avenues. As a result of introduction of these exotic species, phytosanitary problems appeared. Currently there is scarce information on how to evaluate the health of these majestic monocots, in this sense, it is necessary to implement assessment scales to determine the health condition of the most frequently found species to advance on their care and management. The present study had the following objectives: 1) To determine the current state of health of palm trees by means of a scale of visual evaluation of the crown; 2) To know the diversity and structural characteristics of palm trees and 3) To determine the influence of composite variables on the ecosystem services such as the amount of shade provided. Health of palm trees were evaluated two times (dry and rainy seasons in 2022) on 35 transects of 200 m length. An imaginary circle divided into twelfths was overlapped on palm tree “crowns”, and through it, two absolute variables, Live Crown Ratio (LCR) and Crown Quality (CQ) were evaluated. Composite variables were also calculated. The 12/12 health scale adapted in the present study was useful. Four health categories were obtained for the Live crown ratio (LCR): 7.62% of the palm trees were in critical condition, 7.80% were in intermediate condition, 80.36% were in normal condition, and 4.20% were in excellent condition. Meanwhile, for crown quality (CQ), the percentages were 13.50%, 20.00%, 56.96% and 0.43%, respectively. The total height and “crown” diameter showed a positive correlation with the volume composite variables. The shadow area projected as an important ecosystem service increased as the health of the palm trees improved. This is the first study on palm trees health assessment in Mexico City.Full article

The experiment was conducted in the experimental field of the Horticulture Department, University for Development Studies (UDS), Nyankpala campus with the aim of determining the response of three cucumber cultivars (Marketer, Nandini, Pointset) to the application of sulphate of ammonia as top dressing with respect to fruit yield, and shelf life. It was a 3 x 3 x 2 factorial arranged in a randomized complete block design with three replications. Data was collected on total fruit yield, shelf life and percentage fruit decay in storage. Their effect on the varieties differed significantly to a varying degree. The factors, however, had no significant impact and caused no difference in the fruit yield and fruit weight. 15:15:15 NPK effect on the cucumbers caused a high decay incidence when applied alone or in combination with (NH4)2SO4. Therefore, the application rate may be revised or reduced to experiment if decay incidence would decline in storage. Further studies may extensively be carried out to note if varying the rate of NPK would impact positively on the shelf life of cucumber. (NH4)2SO4 effect increased weight loss in cucumbers hence, better storage techniques should be considered by controlling high temperatures. Complete fertilizer; 15:15:15 NPK and (NH4)2SO4 had a positive impact on protein and fibre. Hence, their application is recommended for increasing protein and fibre level in cucumbers.Full article

Cassava crop improvement is a function of selecting superior genotypes that meets the end-users needs and preference. This is done via genotype testing at different environments thereby subjecting the materials to the elements of climate and other environmental factors. In pro-vitamin a cassava genotypes, dry matter (DM), total carotenoids (TC), and fresh root yield (FYLD) are important traits for improving economic status, nutritional health and livelihoods of farmers and processors. This study evaluated the effect of rainfall patterns on 42 provitamin A Cassava accessions for FYLD, DM, TC at different months (6,9&12 months after planting) and for two seasons (2019/2020 and 2020/2021) in Ibadan. The study shows that the relationship between TC and FYLD were more variable at second season than in the first season. The relationships between TC & DM and FYLD & DM at both seasons showed similar variability. The rainfall pattern shows that higher rainfall trend was noticed at the first cropping season (2019/2020) than 2020/2021 cropping seasons. At different months categories and across cropping season, rainfall recorded the least value of 4.58mm at 6 Months After Planting (MAP) which was in the month of December, increased at 9 MAP (Mar) and all through the 12 MAP (107.05mm). Traits relationship with rainfall shows that yield increased with rainfall, DM (25.70%) was highest during the months of least rainfall (4.58mm) and decreased (16.40%) as rainfall (52.09mm) starts during the 9 MAP and at 12 MAP, when the rainfall was 107mm, the DM was 18.76%. Total carotenoids were highest at 6 MAP with 13.76 µg/g when the rainfall was least and decreased (13.04 µg/g) with increased rainfall. During the first cropping season, DM and TC were higher with higher rainfall but with reduced fresh root yield while at second season, when the rainfall was lower, fresh root yield was higher.Full article

The duck industry makes an important contribution to the availability of animal protein sources in Egypt, little known about the genetic parameters, particularly the heritability and genetic correlations of body weight and egg production in ducks. Body weight is the most essential feature for genetic improvement due to its ease of selection, high heredity, and large impact on meat production costs. The target of this study was to evaluate and explain genetic parameters such as the heritability, the genetic and phenotypic correlations, and sire breeding value in Domyati (local) and Khaki-Campbell (foreign) ducks in order to improve body weight and egg traits. A total of 160 (80 Domyati and 80 Khaki-Campbell ducks utilized to measure body weight at 16 and 20 weeks g), as well as 7000 eggs (2500 Domyati and 4500 Khaki-Campbell) to measure egg traits (the egg number, egg weight, and egg mass are all measured throughout the first 90 days of laying). In Domyati and Khaki-Campbell ducks, the heritability estimated for body weight was moderate to high, ranged from 0.35 to 0.40, and 0.21 to 0.30 for egg production. The genetic correlations among body weight and egg traits were all positive and had high values, also among BW16 and BW20 were stronger (0.90); (0.99). So the genetic improvement in BW16 could be followed by an increase in BW20 weeks. It concluded that, the relatively high value of genetic heritability for body weights and egg traits in Domyati and Khaki-Campbell ducks, indicates that it is possible to genetically increase body weight and egg traits through selection and subsequently inbreeding to divide the herd into groups that are selected among themselves to keep their sons.Full article

This study took place in the Far North region of Cameroon. The general objective was to assess the floristic diversity of the undergrowth of Agrosystems in Azadirachta indica. The data were collected in 100 m long by 20 m wide transects surveyed in plantations of different ages. In total, 5 transects were carried out, ie a total area of 1 ha per site. The sampling bands were established using the compass, decameter, GPS and wires. The experimental set-up used was a 5-repetition split plot. A total of 7689 individuals divided into 9 families, 13 genera and 16 species have been identified. Guiera senegalensis and Piliostigma thonningii are the most common in terms of relative abundance. The analysis of the Family Importance Index (VIF) shows overall that the Combretaceae, and Mimosaceae are the most important in ecological terms. While those of the species show that Guiera senegalensis, Combretum micranthum and Acacia nilotica finally for the genera, it is Acacia, Guiera and Combretum which contains the most important ecological indices. The overall density of species within the plots varies between 129 and 105 ind / ha. The basal area varies from 2.02 to 3.88 m² / ha. The Importance Value Index (IVI) is of the order of 300 in the different plots. The floristic diversity of the undergrowth of Agrosystems (average ISH> 2) shows homogeneity and an even distribution between the different plots. Plots with similarity indices of less than 50% do not meet floristic affinity while similarity indices are high in plots with floristic affinities greater than or equal to 50%. The diameter structure showed a predominance of young individuals. This information drawn from the conclusion of the present study shows that they constitute an important argumentation of the advantages so that the services of agricultural development should be interested in the conservation and valuation of such an agroforestry system for the protection of the environment against the climate change mitigation and sustainable development of local communities.Full article
