Response of Okra (Abelmoschus esculentus (L.) Moench) and Weeds to Plant Spacing and Weeding Regime in a Humid Forest Agro-Ecology of South-Eastern Nigeria | Chapter 03 | Recent Advances in Biological Research Vol. 6

Okra (Abelmoschus esculentus (L.) Moench) is a vegetable crop belonging to the family of Malvaceae. It is extensively grown in the tropic and sub- tropics but had its origin in Central Africa. One of the cultural practices that farmers used in controlling weeds in okra farm is spacing. It is a distance between one cultivated crop and another. The spacing between rows and along rows varies one type of crop to another. Field experiment was carried out in late 2015 and repeated in early 2016 cropping season at the Teaching and Research Farm of the University of Port Harcourt, Choba, Rivers State, Nigeria to determine the appropriate spacing and weeding regimes for okra production. Three spacing (60 cm x 15 cm, 60 cm x 20 cm and 60 cm x 30 cm) and three weeding regimes [no weeding, weekly weeding, and twice at 3 and 7 weeks after planting (WAP)] were used. The experimental design was a 3 x 3 factorial scheme laid out in a Randomised Complete Block Design (RCBD) with three replications. The results showed that plant spaced at a closer spacing of 60 cm x 15 cm suppressed weeds better than other spacing in both years of study. Okra performance was better at closer spacing of 60 cm x 15 cm than in other spacing regimes. Similarly, weedy check had higher weed growth and least performance than other weeding regimes. There was significant interaction between spacing and weeding regimes. Plant spaced at closer spacing of 60 cm x 15 cm combined with weekly weeding plots had the lowest weed density and dry weight of 0.00 plants /m2 and 0.00 g/m2 in both years of study. While 60 cm x 30 cm combined with no weeding gave the highest weed density and dry weight (395.00 plants/m2 and 306.33 plants/m2) and (88.33 plants/m2 and 95.33 g/m2) in the late and early 2015 and 2016 cropping seasons respectively. The interaction effect further showed  that the highest fresh pod yield  was obtained from  plant  spaced at 60 cm x 15cm with weekly weeding (3.02 t/ha and 2.26 t/ha)  followed by  60 cm x 15 cm  with twice weeding  at 3 and 7 WAP (2.96 and 2.22 t/ha). While, plant spaced at 60 cm x 30 cm with no weeding had the lowest fresh pod yield (0.08 t/ha and 0.03 t/ha). Since, the yield obtained from 60 cm x 15 cm with twice weeding (3 and 7 WAP) was not statistically different from 60 cm x 15 cm weekly weeding, for economic considering the former could be recommended.

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
