To date, there have been no examples of large-scale control failures due to resistance selected directly by commercial transgenic crops, but resistance to conventional Bt sprays (selected in either the laboratory or the field) has been reported in more than a dozen species of insect. Research ...
When properly understood, these factors can serve as biomonitoring tools to predict system gaps and failures while sustaining functional stability and ensuring the microbial ecosystem [67,75]. For instance, an ecosystem with high richness and evenness (relative abundance) can be an indicator of ...
Cooling from nuclear wars causes temperature limitations for crops, leading to delayed physiological maturity and additional cold stress14. Calorie reduction from agriculture and marine fisheries shows regional differences (Supplementary Fig.4), with the strongest percentage reductions over high latitudes in ...
Let U the random variable be defined by \(n-S\) the number of failures. In the case where S represents the number of infections, U represents the number of uninfected places. The probability to get k infections is given by: $$\begin{aligned} P(S = k) = {n \atopwithdelims ()k...
crops in the European Union. However, the high and persistent level of expression also introduces a considerable risk of pests adapting rapidly to resist genetically engineered toxins. To date, there have been no examples of large-scale control failures due to resistance selected directly by ...
At present, mechanized planting is widely used, but planting failures are frequent in this system, despite advances in mechanization and planting methods. In an attempt to avoid yield reduction, planting density was increased from 24 to 60 buds m−1 of planting furrow, which increased the ...
(direct drilling) and strip-tillage showed that difficulties can gradually be reduced through site-specific technology solutions. The need for subsoiling is not a matter of debate nowadays but rather the timing of operation and the investigation of the duration of the effects. Due to its complex...
4. Changing planting dates results in significant positive yield change in all agro-ecological zones except for the Sahelian zone where delaying planting to late planting date (D3) leads to crop failures. In addition, changing crop cultivar results in significant positive yield change in all agro...
