ON APPROACHES AND APPLICATIONS OF THE WAGENINGEN CROP MODELS
TLDR
An overview of the Wageningen crop and crop-soil modelling approaches is presented and it is concluded that focus is required on a limited number of modules in a more integrated modelling framework for the benefit of analysing, evaluating and designing cropping systems.
Ratio between virtual and visual lesion size as a measure to describe reduction in leaf photosynthesis of rice due to leaf blast.
TLDR
The effect of Pyricularia oryzae, the causal organism of blast in rice, on net photosynthetic rate of rice leaves was measured in the field and in a greenhouse experiment to relate the net photosynthesis rate of diseased leaf area to the photosynthesis of comparable healthy leaf area and disease severity.
Ecological weed management by cover cropping: effects on weed growth in autumn and weed establishment in spring
TLDR
Although a poor competitor in the fall, after incorporation in spring, lucerne had the strongest inhibitory effect on seedling establishment, followed by winter oilseed rape and white lupin, which was strongly correlated to early light interception.
Developing selection protocols for weed competitiveness in aerobic rice
TLDR
Regression analysis revealed that yield and early vigor under weed-free conditions in a single three-replicate trial could be used together in an indirect selection index, explaining 89% and 48% of variation for yield under weed competition and weed biomass, respectively.
RAAIS: Rapid Appraisal of Agricultural Innovation Systems (Part I). A diagnostic tool for integrated analysis of complex problems and innovation capacity
This paper introduces Rapid Appraisal of Agricultural Innovation Systems (RAAIS). RAAIS is a diagnostic tool that can guide the analysis of complex agricultural problems and innovation capacity of
How can field selection for Striga resistance and tolerance in sorghum be improved
TLDR
It is expected that clarification of the relation between Striga infection level and yield loss, provides a solid basis for the development of unambiguous tolerance measures in the field.
Field weed population dynamics : a review of model approaches and applications
TLDR
It is hoped that the overview provided by this review will inspire weed modellers and that it will serve as a basis for discussion and as a frame of reference when the modelling of weed populations to a new level, developing new approaches and tackling new application domains.
Cultivar weed-competitiveness in aerobic rice : heritability, correlated traits, and the potential for indirect selection in weed-free environments
TLDR
Indirect selection on these two traits was predicted to be efficient for improving yield under weed competition and weed-suppressive ability of aerobic rice.
Focus on ecological weed management: what is hindering adoption?
Despite increased concerns regarding the heavy reliance of many cropping systems on chemical weed control, adoption of ecological weed management practices is only steadily progressing. For this
Comparing rice germplasm groups for growth, grain yield and weed‐suppressive ability under aerobic soil conditions
TLDR
Indica germplasm seemed to be most suitable for breeding high-yielding and weed-suppressive aerobic rice for the tropics, and the relationship of WSA with various traits within tropical japonica germ plasm revealed that fast early growth, rather than plant erectness, is crucial to WSA.
