Simulation model for maize crop growth based on acquisition and allocation processes for carbohydrate and nitrogen

Autor: Bonato, O. Schulthess, F. Baumgaertner, J.U.

A population model for maize growth and development driven by temperature, solar radiation, soil water and soil nitrogen is presented. A time-varying distributed delay model is used to describe the dynamics of the attributes number, biomass and nitrogen belonging to leaf, root, stem, grain, rachy...

Soil improvement by trees in sub-Saharan Africa

Autor: Buresh, R.J. Tian, G.

Trees can influence both the supply and availability of nutrients in the soil. Trees increase the supply of nutrients within the rooting zone of crops through (1) input of N by biological N2 fixation, (2) retrieval of nutrients from below the rooting zone of crops and (3) reduction in nutrient lo...

Nitrogen effects on Striga hermonthica infestation, grain yield and agronomic traits of tolerant and susceptible maize hybrids

Autor: Kim, S.K. Adetimirin, V.O. Akintunde, A.Y.

phytoparasite, Striga hermonthica (Del.) Benth., infests millions of hectares of cultivated fields of cereal crops in sub-Saharan Africa. Yield losses are often 70 but can be as high as 100% and farmers often abandon infested fields and move to new areas. The objectives of this study were to inve...

Nitrogen and phosphorous uptake by potato (Solanum tuberosum L.) and their use efficiency under potato-legume intercropping systems

Autor: Gitari, H.I. Karanja, N. Gachene, C.K.K. Kamau, S. Sharma, K. Schulte-Geldermann, Elmar

Competition for nitrogen (N) and phosphorous (P) under potato-based intercropping systems decreases the level of nutrients available for potato and subsequently influences nitrogen and phosphorous use efficiency. A field trial was conducted for four consecutive seasons between 2014 short rains an...

Root adaptations to soils with low fertility and aluminium toxicity

Autor: Rao, Idupulapati M. Miles, John W. Beebe, Stephen E. Horst, Walter J.

BACKGROUND Plants depend on their root systems to acquire the water and nutrients necessary for their survival in nature, and for their yield and nutritional quality in agriculture. Root systems are complex and a variety of root phenes have been identified as contributors to adaptation to soils w...

Influence of plant density and growth habit of common bean on leaf area development and N accumulation

Autor: Clavijo Michelangeli, José A. Ricaurte Oyola, José Jaumer Sinclair, Thomas R. Rao, Idupulapati M. Beebe, Stephen E.

Crop yield requires leaf area to intercept solar radiation and to undertake photosynthesis, both of which depend on nitrogen (N) accumulation. Further, the amount of accumulated plant N at the beginning of seed fill serves as the reservoir for N required in synthesizing the proteins in developing...

Genotypic differences in symbiotic nitrogen fixation ability and seed yield of climbing bean

Autor: Barbosa Torres, Norma Constanza Portilla, Elizabeth Buendía Castellanos, Hector F. Raatz, Bodo Beebe, Stephen E. Rao, Idupulapati M.

Symbiotic nitrogen fixation (SNF) contributes to improve grain yield under nitrogen (N) deficiency. Climbing beans are known to be superior to bush beans in their potential for SNF. The main objectives of this study were to: (i) quantify genotypic differences in SNF ability of climbing beans usin...

Increasing nutrient use efficiency in West-African agriculture: The impact of micro-topography on nutrient leaching from cattle and sheep manure

Autor: Brouwer, J. Powell, J.M.

In African agriculture, availability of nutrients for crop production can be increased using external inputs such as mineral fertiliser. However, for many African farmers the large scale use of external inputs will remain beyond reach for the foreseeable future. There is, therefore, also a need f...
