Different responses of plant genotypes to the change of environmental conditions have been the most important and challenging issue for plant breeders and agronomists for the selection of superior genotypes. Cumin is one of the most important medicinal and aromatic plants in Iran that are strongly affected by varying environmental conditions. This study was aimed to investigate E×SD interaction...

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...

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 </...

to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...

to evaluate the effects of on-farm seed priming treatments and sowing dates on rate and percentage of seedling emergence, biological yield and some physiological indices of corn hybrid (sc. 260) an experiment was conducted in hamedan, iran in 2010. a split plot in a randomized complete block design with three replications was conducted. main plots include three sowing dates (early, on-time and ...
