determination of the response of differentcrop varieties to environmental variables from planting to harvest is one of the fundamental pillars of agriculture planning to achieve maximum yield and desirable quality. changing planting date by effect on vegetative and reproductive growth period and balance between them, will affect yield and product quality. in order to study the responses of four...

to determine the best planting date and irrigation schedule in a cotton field (gossypium hirsutum var.varamin) in garmsar region an experiment was conducted in 2011. the experimental design was splitplot based on randomized complete block with three replications. three irrigation termination dates (2011sep 11th, 2011 sep 21st and 2011 oct 2nd) arranged in main plots as main factor and three pla...

Corn (&a mays L.) growth has been shown to be affected by planting date and amount of residue on the soil surface. The objective of this study was to determine if the adverse effects of cool soil temperatures on early seedling growth often associated with surface residues can be overcome by planting at later dates. Corn was planted at several planting dates (late April through early June) into ...

Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...

Temperature changes occur in nature faster than other stressors. Plants due to inability to move and change their position, are exposed to extensive variations in daily or seasonal temperature, and therefore, should quickly and effectively adapt to temperature stress. In order to study the effects of heat stress on physiological traits of forage maize hybrids, a factorial split plot experiment ...
