Understanding spring wheat growth and development is essential to achieving optimum productivity. Spring wheat proceeds through a sequence of easily recognizable growth stages that are described by several staging schemes, the most comprehensive being the Zadoks system. Growing conditions and management decisions at any stage can impact the crop’s . Hard red spring wheat, durum wheat and oats all had lowest yields in the s and highest yields in the s, with increases in yield averag 24 and 58 bu/ac respectively (Fig. 3, 4 and 5). Statistically speaking, average barley and spring wheat yields were consistent through the s and 50s, increased in the 60s, and then increased.
average precipitation and remained in severe to exceptional drought conditions. In contrast, Nebraska through the upper Great Plains and across the Pacific Northwest entered the winter with very good soil moisture conditions throughout the soil profile which extended into the spring. The wheat crop in parts of southern Kansas, Oklahoma. At least 80% of the more than 7 M ha of spring wheat grown each year is planted to CWRS varieties (Statcan ), regardless of the fact that Canadian prairie spring wheat has a 15–20% higher yield potential than CWRS (Campbell et al. ). In semi-arid regions, spring wheat is traditionally grown in cropping systems that include summer Cited by:
Wheat accounts for around 20% of the calories that humans consume and as such is the leading source of plant protein. It is well-known that wheat productivity is sensitive to both natural climate Author: Ehsan Najafi.

Climate change, meanwhile, is worsening and threatening our current food supply, particularly wheat.

To evaluate dependence of spring wheat grain yield on temperature and precipitation, coefficients of correlations were calculated for the means of on-station grain yield and weather parameters in June, July, and April-August (Table 4). The month of June demonstrated the highest correlation with yield for all three weather by: 1.

Optimum population is a function of the production of environment, the yield goal, and the planting date.
A higher seeding rate is required by low tillering varieties. Seeding rates should be increased by 1% for each day planting is delayed up to a maximum rate of million seeds per acre. Delay in planting reduces yield potential and tiller.Precipitation in June was very critical for spring wheat, with significant positive correlations with grain yield at 6 of 19 sites.
Higher dependence of yield on June precipitation was related to the amount of rainfall received during April-August: at drier sites the response was much more pronounced (S1 Fig).Cited by: 1.Much of this wheat, due to unfavorable moisture and temperature conditions (during the growing season), is even in an average year, below the standard expected of hard red spring wheat.
