Most African countries struggle with food production and food security. 6 These issues are expected to be even more severe in the face of climate change. Our 7 study examines the likely impacts of climate change on agriculture with a view to 8 propose directions to adapt especially in regions where it might be crucial. 9 We use a crop model to evaluate the impact of various sowing decisions on ...

> Sowing crops following cover crops on forage may cause injuries andproductivity reduction, due reasons as allelopathy or glyphosate residues. Theobjective of this study was to evaluate the influence of differing periods betweencover crop (Urochloa ruziziensis) desiccation with glyphosate and sunflower(Aguará 4) sowing in a no-tillage system on crop development and productivity.Two assays were...

To study the effect of sowing date on quantitave and qualitative traits of soybean in Shahrekord region, an experiment was performed as split plot based on randomized complete blocks design with four replications at Agricultural and Natural Resources Research Centre of Chaharmahal-va-Bakhtiari, Shahrekord, in 2008. Four sowing dates (May 5, May 20, June 4 and June 19) and four varieties (M9, M7...

Wheat (729.8 million tons) is second to rice as the main human food crop (FAO, 201415). In India, wheat is cultivated extensively in North-Western and Central zones. The area, production and productivity of wheat in India and Haryana during 2014-15 is 31.46 mha, 86.53 mt, 2749 kg ha -1 and 2.60 mha, 10.35 mt, 3980 kg ha -1 , respectively (Anonymous, 2014-15). Late sowing of wheat is a major pro...

Background & aim: Saline lands can be utilized by planting native medicinal plants tolerant to salinity. The quantity and quality these plants are changed during various seasons in agriculture systems. Thus, this study carried out under salinity stress in order to examine the effect of sowing in two seasons on growth characteristics and essential oil  components of ajowan (Carum capticum </...

Transplanting or pot culture has been mentioned as a promising approach to increase crop yield and decrease irrigation water use in recent years. Using simulation models to assess pot culture is a valuable way in investigating the effect on yield, water consumption and other properties of crops such as soybean. For this purpose, several pot culture levels (seedling sizes) plus direct sowing wer...

The positioning of pods in common bean directly affects grain losses mechanized harvesting. However, only few studies have assessed facttors that can affect positioning. objective this work was to determine the effect plant density, nitrogen fertilization, and fertilization depth on distribution bean. field experiments were carried out two cropping seasons, 2017 2018, during winter period Cerra...

Soybean (Glycine max (L.) Merr.) may contribute to the agro-ecological transition of cropping systems in Europe, but its productivity is severely affected by summer drought. New drought-avoidance strategies, such as early sowing, require cultivars with high plant growth under suboptimal conditions. This study aims at phenotyping early-stage root and shoot traits 10 commonly grown Europe. Cultiv...
