A sensitivity analysis of the responses of crops to the chosen production adaptation options under regional climate change was conducted in this study. Projections of winter wheat production for different sowing dates and cultivars were estimated for a major economic and agricultural province of China from 2021 to 2080 using the World Food Study model (WOFOST) under representative concentration...

In order to compare  the seed production of Vicia villosa under different cultivation seasons and methods, the seeds were initially collected from natural habitats similar to the m...

Hybrid seed set on the female line depends primarily its flowering synchronization with restorer (R), therefore, sowing of male and lines must be planned properly to achieve this. Field experiments different dates (May 1st, May 15th, 30th) R (Giza 178R, Giza 179R, 181R) cytoplasmic sterile (CMS) (IR69625A, IR70368A, IR58025A, K17A, G46A) were carried out at farm Sakha Agricultural Research Stat...
