Identification of Agromorphological Determinants Favoring the Propagation of Bacterial Disease in Agroforestry Farms of Cashew Trees in Côte d'Ivoire
No full textIn Côte d'Ivoire, cashew cultivation faces several health obstacles. Among these problems, bacteriosis causes extensive damage to twigs, leaves and fruits, lowers the quality of crops and causes yield losses. The spread of this disease would be under the determination of the morphological characters of the cashew tree. The objective of this study is to search for agro-morphological determinants that influence the spread of bacteriosis in agroforestry systems in Côte d'Ivoire. To achieve this objective, 30 cashew trees spread across 26 agroforestry cashew orchards in the Korhogo, Sinématiali and Boundiali departments were chosen and geolocated. The study factor is the clone, consisting of 30 cashew genotypes, with 13 modalities. The collected data was subjected to descriptive analysis, correlation test, ACP and ascending hierarchical classification (CAH). The results obtained showed that the size and leaf areas and size of cashew trees are determinants that promote the spread of bacteriosis in these 30 cashew genotypes. Following this result, the ascending hierarchical classification (CAH) made it possible to screen the genotypes into three groups. These results should contribute to the agroecological management of bacteriosis, to enhance and intensify agroforestry cropping systems in Côte d'Ivoire
Recent Trend of Precipitation and Crop Planning in Rajshahi Region of Bangladesh
No full textThe study was carried out for investigation and analysis of long-term (45 years) monthly rainfall data of Rajshahi from 1975 to 2019 for better selection of crops and agricultural technology in this region of Bangladesh. The rainfall trend was determined using parametric and non-parametric method. Probability analysis of rainfall was performed for estimation of dry, wet, and average year rainfall. The results revealed negative trend of yearly rainfall, but it is statistically insignificant. By non-parametric method, ‘no trend’ was observed for yearly rainfall. Increasing trend of monthly rainfall during March and May and decreasing trend in other months were observed. The rainfall deficit period continued from November to March, and in some instant up to April (rainfall<PET).Total deficit for dry, wet, and average year were found as 488.2 mm, 405.7mm and 426.1mm respectively. By adopting low water-demanding cropping patterns during the deficit period, the withdrawal of groundwater can be minimized

Effects of Extreme Flooding on Output of Selected Crops in Anambra State, Nigeria from 1990 to 2019
No full textThe study has analyzed effects of extreme flooding on output of selected root and tuber crops in Anambra State, Nigeria for the period of 1990-2019using secondary data collected on cassava, yam and sweet potato output from the agricultural production survey of Anambra State Agricultural Development Programme and annual averages of rainfall from the Nigeria Meteorological Agency inAwka station. Data collected were analysed by using multivariate simple linear regression and trend analysisin linear trend analysis and line graph. Results respectively showed an increasing trend in output of cassava, yam and sweet potato within the researched period with a depression in output of cassava and yam in 2014 and 2015. The regression results showed that coefficients of determination (R2) values of yam output were (0.620), cassava output (0.560) and sweet potato (0.580), which implied that 63%, 56% and 58% changed in output of roots and tuber crops accounted for rainfall within the research period. Specifically, rainfall (0.002) was positively related to yam output at (p<0.05). This implied excessive amount of rainfall resulting flooding, which influenced the output of production of yam. Rainfall (-0.015) and (-0.003) were negatively related to output of cassava and sweet potato at 5% probability level, which indicated extreme rainfall translating into flooding, which adversely affected the output of cassava and sweet potato in this area. The result of the tested hypothesis showed that extreme flooding had significant negative effects on output of roots and tuber crops in the researched area. Based on results, it was concluded that extreme flooding deleteriously affected output of root and tuber crops in Anambra state, Nigeria. Therefore, farmers were advised to change their crop production technologies including time of planting to suit changes in rainfall pattern in order to avert their adverse effects

No full textTomato (Lycopersicon esculentum) is a popular and important crop as it is consumed worldwide. It serves as a source of nutrients such as vitamins A and C. In Ghana, tomato production contributes to agricultural GDP, employment creation and foreign exchange earnings. However, tomato production is faced with challenges that hamper productivity. This has been attributed mainly to attacks by pests such as fruit borers. Therefore, this study was conducted to ascertain the characteristics of tomato farmers in Sekyere Kumawu and Asante Akim North districts in Ghana and their knowledge on fruit borers. Structured questionnaires were administered to gather data from sixty respondents who were sampled through a multistage sampling technique. Results from the survey showed male dominance in commercial tomato production in both districts with an average age of 43 years, which falls within the active working age group. Majority of the farmers indicated that they were into tomato production for commercial purposes, and practice sole cropping. More than 60% of the farmers revealed the fruit borer as a major pest causing yield losses of about 27% on average on their farms. Moreover, it was found that majority of the respondents control the fruit borer with synthetic chemicals

Farmers’ Perspective on Insect Pests that Affect Vegetables in Protected Structures with Emphasis to Tuta absoluta (Meyrick) in Lesotho
No full textProtected farming is one of the innovations used by farmers to control pests and climatic conditions and therefore improve yield of vegetables. However, these structures also provide an ideal environment for biotic factors such as insect pests and diseases. In this study, a survey of 60 farmers was conducted to determine the types of vegetables cultivated under protected structures, insect pests and management practices employed by farmers using structured questionnaires. Data was analysed through descriptive statistics using Statistical Package for Social Sciences (SPSS). The results showed that most farmers grew tomato, cabbage, swiss chard, rape and peppers. Farmers considered insect pests as the major constraint to vegetable production. The most important insect pests found infesting farmers’ vegetables were aphids (Aphis gossypii), tomato leafminer (Tuta absoluta), bagrada bug (Bagrada hilaris) and cutworm (Agrotis ipsilon). To manage these pests, farmers relied heavily on chemical pesticides which are dangerous to them and to the environment. It is therefore important to develop an integrated pest management plan that farmers can use to reduce use of pesticides
