Diseases of Different Crops in Zoba Anseba of Eritrea | Book Publisher International

Eritrea is a country of North Eastern Africa, areas where sorghum is originated and believed to be the center of its domesticated. The country bordered on the east by the Red Sea, the south by Djibouti and Ethiopia and the north and west by Sudan. It has a land area of 125,000 square kilometers. According to Grando et al., (2010), of the total potential arable land the area under cereal cultivation is estimated as 463,926 hectares (average of 2005-2008).

The major and important field crops in Eritrea are sorghum and pearl millet. In the order of importance by area in Eritrea (average of 2005-2008 with 463,926 hectares) are: sorghum (machala1 56%), pearl millet (bultuk 13%), barley (segem 9%), finger millet (dagusha 6%), tef (tef  6%), maize (offun 5%), wheat (sernay 4%) and hanfets (mixture of barley and wheat, 1%). Pearl millet (Pennisetum glaucum) is the most widely grown type of millet and Sorghum (Sorghum bicolor) native to Africa with many cultivated forms now is an important crop worldwide. They are the most important crops for both human consumption and animal fodder ranking after paddy, wheat and maize in the world.

The crop yield is adversely affected by several biotic (animate) and abiotic (inanimate) factors. More than 100 diseases caused by different microorganisms have been reported. Among this downy mildew, smut, anthracnoses are of economically important in major growing areas of the sub zoba Hamelmalo and zoba Anseba. However the average yield in the major sorghum growing areas is <0.673 t/ha in Hamelmalo region, while Sudan (neighbor of Eritrea) one of the largest producers of sorghum in the world.

The most common reasons for low yields are drought, pests, diseases and weeds (Striga) wild sorghums and their intermediates with cultivated sorghum and lack of improved practices (Tesfamichael, 1999 and Obilana et al., 2002). Seven fungal genera were encountered in high percent frequencies of seed borne fungal pathogen in sorghum, pearl millet and groundnut collected from farmers own saved seeds from Zoba Anseba (Syed et al., 2013).

The common diseases occurred on these crops are: Downy Mildew, Leaf blight, Rectangular Leaf spot, Anthracnose and red rot, Rust, Grain smut, Loose smut, Long smut, Ergot or Sugary disease, Head mould and Phanerogamic parasite (Striga asiatica). During a decade period of time investigations some of the following diseases have been observed.

Empowerment and Leader Member Exchange towards Organizational Citizenship Behavior Readiness among Government Workforce in Malaysia | Book Publisher International

  State agencies are among the most significant entities that represent the public's needs, and their programmes are essential to a state's and the nation's economic growth and development. State agencies have been rife by public concerns for years, as demonstrated by the Public Complaints Bureau, as problems of inefficiency in service quality and delivery have yet to meet the public's standards. With the support of 15 employees from state agencies on Malaysia's east coast, this study aims to achieve three targets. The first and second objectives are to investigate the ties between leader-member exchange (LMX) and OCB empowerment. The final aim is to define the most significant factors that affect OCB willingness. A total of 288 people took part in the survey, which was conducted using a cluster sampling process. The survey items had achieved the necessary reliability, according to the pilot test results, and some sub-dimensions were renamed after factor analysis.

Re-asserting Cultural Perspectives: Old People and New Ideas in Bole Butake’s Lake God and The Survivors and Sankie Maimo’s Succession in Sarkov | Chapter 10 | Perspectives of Arts and Social Studies Vol. 2

African cultures have undergone transformations from the colonial period to the present, often to the detriment of its cultural evolution and within the larger global community. As it were, colonial education subordinated African communalism and created in its place an anti-African spirit evident in the assimilation of western values. This did not only end up in a kind of cultural betrayal, but also posed as a serious threat to the dignity and identity of the people. Those who fall prey to this kind of cultural imperialism are the young people who are often irrationally carried away by western fashion and modes that they tend to neglect and/or forget their cultural ways of life as they join the race of “progress.” This situation has given rise to a conscious effort by creative writers to re-assert and protect African values while at the same time liberating themselves from the longstanding western effort at suppressing, controlling and dominating their thoughts particularly through n

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t
