Climatic gradients along the windward slopes of Mount Kenya and their implication for crop risks. Part 2 : crop sensitivity.
2016
16 pages; International audience; Mount Kenya is an equatorial mountain whose climatic setting is fairly simple (two rainy seasons in March–May, the Long Rains, and October–December, the Short Rains) though concealing significant spatial variations related to elevation and aspect (part I, Camberlin et al., 2014). This part II is dedicated to the sensitivity of sorghum yields to climate variability in space and time, with a focus on the intra-seasonal characteristics of the rainy seasons. To that aim we use the crop model SARRA-H calibrated for the region and fed with rainfall, temperature, wind speed, humidity and solar radiation data over the period 1973–2001 at three stations located on t…
Implémentation et évaluation du modèle de culture de pois (Pisum sativum L.) AFISOL sous la plate-forme logicielle RECORD
2013
The pea crop is very beneficial since it fixes atmospheric nitrogen and protein source for animals as well as humans. To overcome the deficiency of performance which it suffers, research aims to develop new varieties tolerant to stress (biotic and abiotic). A numerical model of the functioning of the Pea "AFISOL" was designed in Excel. However, the model in EXCEL does not help the use of the model and its accessibility to a large number of people. The objective of this internship is: - To implement the model AFISOL in the platform modeling RECORD developed by INRA. This platform uses the VLE software based on C + + language. - To make a study of sensitivity analysis showing the effect of th…
GeneSys-Beet: A model of the effects of cropping systems on gene flow between sugar beet and weed beet
2008
A weedy form of the genus Beta, i.e. Beta vulgaris ssp. vulgaris (hence ''weed beet'') frequently found in sugar beet is impossible to eliminate with herbicides because of its genetic proximity to the crop. It is presumed to be the progeny of accidental hybrids between sugar beet (ssp. vulgaris) and wild beet (ssp. maritima), or of sugar beet varieties sensitive to vernalization and sown early in years with late cold spells. In this context, genetically modified (GM) sugar beet varieties tolerant to non-selective herbicides would be interesting to manage weed beet. However, because of the proximity of the weed to the crop, it is highly probable that the herbicide-tolerance transgene would b…
