There were four sowing dates, and two tillage systems with no variation in planting distance in the two cropping seasons. The design used was Randomized Complete Block Design (RCBD) with three replications. There were three plots for each sowing date within each replication. Seeds were sown at the rate of 1 m × 1 m, with four seeds per experimental unit. Data for disease incidence and severity was recorded every fortnight, commencing three weeks after emergence (WAE) and for a period of eight weeks for each sowing date. Disease incidence and severity was determined using Microsoft Excel 2010 and the data was subjected to statistical analysis and the means separated by Duncan Multiple Range Test (DMRT) at 95% confidence interval. In addition, the relationship between disease incidence and disease severity was also determined using Pearson correlation. Analysis of variance showed that there was no significant difference in leaf spot disease incidence at till and no-till units within this study period irrespective of sowing date. However, significant differences in leaf spot disease incidence and severity was recorded between the two cropping seasons. Sowing date four recorded the highest disease severity (1.611 ± 0.73) compared to sowing date two and three which was significant but comparable to sowing date one. The lowest disease severity (1.257 ± 0.697) was documented at sowing date two compared to sowing date one and four but comparable to sowing date three.

The surveys were realized on 50 households in the village and phytosociological plants in corn, millet, cotton and peanuts cultures. The data analysis by statgraphic and Excel and Principal Component Analysis （PCA） showed that maize production （1,200 kg/ha） ranked first at the expense of cotton （640 kg/ha）. They negatively affect climate change （temperature increase （26%）, rain drop （20%）, land reclamation （18%） and flooding （12%））. Surveys of vegetation on three acres cotton fields （76.17%）, millet （81.06%）, corn （80.32%） and groundnut （83.56%） showed that there is no significant difference （P = 0.05） on the specific contribution of wood of different types of farming practices. Adventists species herbacious like Thelepogon elegans （27.84%）, Hyptis spicigera （19.31%）, Teramnus labialis （15.86%） have most important contributions in specific cultures. Methods of crop treatments have a destructive impact on the environment and the loss of biodiversity and the invasion of crops by adventists. Co-management, crop rotation, association of cultures, community forest management, agroforestry and training farmers in the use of inputs will reduce the potential risks of farming practices.展开更多

The objective of this work was to study the development of vitroplants introduced into traditional and modem palm of the Errachidia region. The procedure followed is to make descriptive diagnoses in different sites where the palm was introduced and to evaluate the mortality of plants and cultural practices. The mortality rates varied from 78% to 19% in new plantation depending on the cultivation technique used. At the traditional palm, the rate of recovery ofplantlets was zero. The mortality is higher in Nejda cultivar compared to Boufegouss. This variety also presented a better adaptation in terms of shoot height in comparison with the development of Nejda and Mejhoul varieties. The production of offshoots as well as inflorescences takes place three years after plantation. The importance of improving cultivation techniques in date palm for the development of this sector in Morocco is discussed.展开更多

When a woman dies, in most African societies, her legacy is usually inherited by the husband, children, and her family. But if a man dies, the widow, usually experiences false accusations of killing her husband to deny her share of her husband＇s properties. This paper examines how the dynamics of cultural practices in Nigeria promotes abuse of inheritance rights of women and discusses the possibilities of using Islamic inheritance rules as a divine solution to the abuse of inheritance rights of women. The research questions as follows： what is the nature of women＇s rights to father＇s estate？ What is the nature of widow＇s right to the husband＇s estate？ What is your perception about the Islamic law of inheritance？ The data for this study were collected using questionnaire and simple percentage was used for the analysis. In this respect, a questionnaire was administered to 220 women who were purposely selected from the three major tribes in Lagos state, Nigeria. The result showed that various cultures in Nigeria favour male child, grant male higher rights to land and other properties and promote abuse of inheritance rights against women.展开更多

Cultural practices, such as sanitation and pruning frond bases, hand collection of larvae during regular annual service work and light traps with solar energy were practiced annually in one orchard for five years. In the second orchard, cultural practices were applied for two years, light trap for one year only, and no hand collection of larvae was done during the period. The third orchard was used as a control treatment. Results showed reduction in population density of larvae （91.6% and 53.0%） and adult （76.1% and 41.1%） ofOryects spp. in the 1st and 2nd orchard, respectively The results also demonstrated the impact of moon light phases on the number of Oryctes spp. adults caught by light trap and the existence of an inverse relation between moon light and flight activity of adults. Biological experiments also revealed that entomopathogenic fungi can cause high mortality rate reaching 100% after 29 d. Beauveria bassiana scored higher mortality rate in short time, especially at concentration of 1 × 10^11 conidia/mL with LT50 = 12.75 and LT90 = 20; while, Metarhizium anisopliae caused the higher percentage of malformed adults. The results depicted the effectiveness of some integrated ecological sound control methods for monitoring and population suppression of Oryects spp. in date palm orchards.展开更多

Furthermore, national wealth plays a moderating role between national culture and entrepreneurial activities. Datasets from the Global Leadership and Organizational Behavior Effectiveness （GLOBE） project and Global Entrepreneurship Monitor （GEM） study were analyzed. We find that there are interaction effects between GDP, a proxy for national wealth, and several cultural dimensions on entrepreneurial activities. More traditional cultural variables （in-group collectivism, humane orientation, and power distance） enhance early-stage and established entrepreneurship in low- and medium-GDP countries, but hinder early-stage and established entrepreneurship in high-GDP countries. More modernistic cultural variables （performance orientation, future orientation, and uncertainty avoidance） promote high-growth and high-innovation entrepreneurship in some situations, especially in high-GDP countries. Implications and limitations are discussed.展开更多
