Using childhood landscape memories to uncover the dynamics of Anthropocene in African Urbanscapes

People and Nature, EarlyView.
Abstract This perspective provides a reflective account of our personal experiences as African professors and lecturers in diverse fields of environmental sciences encountering the urban Anthropocene. Here, we explain the nature of the unprecedented, potent and hidden changes in our lived environments.

Effects of Irrigation and Nitrogen Levels on the Yields of Guinea Grass, Para Grass, and Guinea Grass-Kudzu and Para Grass-Kudzu Mixtures in Lajas Valley

The Journal of Agriculture of the University of Puerto Rico, 1965
A field experiment was conducted at Lajas Substation in order to study the effects of three irrigation and three nitrogen levels on dry-matter yields of Para grass, Guinea grass, and the mixtures of these grasses with tropical kudzu. Some plots were frequently irrigated when the average soil-moisture suction in the active root-zone reached 0.7 atm. and

Differential vegetative and reproductive performances among fifteen guinea grass hybrids [PDF]

Pesquisa Agropecuária Brasileira, 2002
The main scope of this work was to detect (Panicum maximum Jacq.) genotype differences as to morphoagronomic and seed quality indices, and to establish character correlations useful for determining vegetative and reproductive trends. Besides the flowering cycle, eight phenological and two seed quality traits were scored in a greenhouse randomized ...

Polycyclic Aromatic Hydrocarbons in Soil and Vegetation of Niger Delta, Nigeria: Ecological Risk Assessment

Journal of Toxicology, 2023
The Niger Delta, Nigeria, is noted for crude oil exploration. Whereas there seems to be a handful of data on soil polycyclic aromatic hydrocarbon (PAH) levels in this area, there is a paucity of studies that have evaluated soil and vegetation PAHs ...

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Rubisco small subunits of C4 plants, Napier grass and guinea grass confer C4-like catalytic properties on Rubisco in rice

Plant Production Science, 2019
Overexpression of Rubisco small subunit (RbcS) of C4 plant, sorghum (sorghum bicolor) was shown to enhance the catalytic turnover rate (kcat) of Rubisco in rice (Oryza sativa).

VEGETATIVE DEVELOPMENT AND GROWING DEGREE-DAYS OF TROPICAL AND WINTER FORAGES [PDF]

Engenharia Agrícola, 2019
One of the limitations to producing irrigated forages is setting suitable biometric parameters to establish the entrance of animals to grazing areas. Such parameters can be measured or even estimated.

Effects of intensity and frequency of defoliation on a mixture of guinea grass (Panicum maximum cv. Coloniao) and Verano stylo (Stylosanthes hamata cv. Verano) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Plant Science at Massey University [PDF]

, 1985
A study was conducted in a glasshouse to determine the effect of defoliation treatments comprising combinations of two intensities (7.5 cm and 15.0 cm cutting height) and three frequencies (2, 3 and 6 weeks) on production, botanical composition and crude
