The model was evaluated using historically recorded temperature data (20 years, 1999鈥 2018) to simulate harvest date, which was within the range of observed harvest dates. The interannual range of estimated harvest dates is 7鈥 10 days for spring barley and 5鈥 10 days for winter wheat. ...
Research was conducted during 20072008 to determine if vegetation indices could be used as indicators of winter wheat maturation. The cultivar Jingdong 12 was planted under four nitrogen treatments, and reflectance and agronomy parameters were measured on five different harvest dates. In maturation ...
Wheat plants lose hardiness when warm temperature occurs followed by cold fronts. Planting dates determine the growth and development patterns of wheat. In Kansas, planting dates are from September 10 to October 25 for optimal yield outcomes and to take advantage of the weather. Much earlier ...
The aim of this research was to determine the effect of different sowing dates on growing period, yield and some yield components of three bread wheat (Tri... T Dokuyucu,A Akkaya,D Yigitoglu - 《Journal of Agronomy》 被引量: 16发表: 2004年 Effect of Sowing Date and Weed Control on Gra...
Predictions of the date of harvest of vining peas (Pisum sativum L.) were performed by means of statistical models. Simple models based on sowing-to-harvest prediction criteria and two-component models based on a combination of sowing-to... E.,Friis,and,... - 《Field Crops Research》 被...

The forecast model for the winter wheat harvest period considered the sowing date as the first day of calculation, with the dates of the different phases of the winter wheat growing period converted into growing days to facilitate statistical analysis. Based on the remote sensing data of the sate...
A Leap Day is added to the calendar every four years (an extra day on February 29) to keep the equinox and solstice dates lined up with the seasons. The day that the winter solstice occurs is the shortest day and the longest night of the calendar year. After the winter solstice, the ...
“We are now into the ideal planting dates which as you know are from 1 May until 15 May. “Deliveries have now been fast-tracked with a substantial amount of inputs being delivered over the weekend to ensure that the remaining farmers can plant their winter wheat crop in time. ...
