Abstract:
... The introgression of awns as a source of photoassimilates during grain filling has received has long been of particular attention in wheat. Although the benefits for average grain weight (AGW) seem consistent, those for yield still remain unclear, and the causes for the improved AGW have not been examined. In this study we carried out three field experiments. In two of them, one in CIMMYT (Mexico) ...

Abstract:
... Large databases containing producer field-level yield and management records can be used to identify causes of yield gaps. A relevant question is how to account for the diverse biophysical background (i.e., climate and soil) across fields and years, which can confound the effect of a given management practice on yield. Here we evaluated two approaches to group producer fields based on biophysical ...

Abstract:
... Phosphorus (P) deficiency is a major yield constraint for lowland rice production on highly weathered soil in Sub-Saharan Africa. To overcome this constraint, we examined the effect of dipping seedling roots into a P-enriched slurry before transplanting (P-dipping) on yield and P use efficiency in the typical P-deficient lowlands in the central highlands of Madagascar. Experiment 1 was conducted a ...

Different fertilisers were field tested to investigate whether they (1) suppress the obligate parasitic weed Striga asiatica and the facultative parasitic weed Rhamphicarpa fistulosa, and (2) favour rainfed rice yields under parasitic weed infestation. Four years of experiments were conducted in southwest Tanzania, in a S. asiatica-infested rainfed upland and a R. fistulosa-infested rainfed lowlan ...

Abstract:
... The impact of fertilisation strategies on bread-making quality of wheat has been investigated extensively, while only few studies have been carried out on minor supply-chains, such as the biscuit production chain, whose products require a low protein content (< 10.5 %) and weak gluten strength (< 110 J 10⁻⁴). The aim of this work was to obtain insight into the effect of N fertilisation strategies ...

Abstract:
... Crop production in Sub-Saharan Africa (SSA) is constrained by rainfall variability and declining soil fertility. This has over time led to a decrease in crop yield, among them also maize. This decrease is also experienced in the sub-humid and semi-arid locations of Kenya. Among the commonly used soil and water management practices in SSA are Conservation Agriculture (CA) and integrated soil fertil ...

Abstract:
... Maize is one of the three major grain crops in China; it is widely planted in Northeastern China (NEC), Northern China (NC) and Northwestern China (NWC). However, large regional variations in maize yield using the same cultivar and management measures occur due to climate diversity. It is important to clarify the differences in regional maize production and climate resources in order to improve re ...

Abstract:
... Growing interest in soybean (Glycine max (L.) Merr.) cultivation, especially in the temperate climate zone, necessitates the search for high-yielding varieties with an optimal growing period. In Europe, it is recommended to cultivate early (00) and very early (000) varieties, which due to their biology form the first pair of pods very low, just above the ground. This unfortunately generates losses ...

Sub-surface fertilizer application at planting (i.e., starter fertilization) is a common practice in U.S. corn (Zea Mays L.) production to improve early-season nutrient uptake, nutrient use efficiency, and plant growth, especially under cool and moist spring soil conditions. However, yield increases from starter applications can vary across production systems and environments. Here, we use a meta- ...
