Using the hybrid population Donskaya Ostistaya X Mironovskaya 808 (F6) and a chemically induced mutant (M6) of Mironovskaya Yubileinaya, positive selection was made for grain weight/plant and positive and negative selection for grain weight/main e...

In trials in 2000-2001, winter wheat cultivars Iwainodaichi and Chikugo were treated with a sidedressing of 500 kg N/ha applied on one of 10 dates between 5 January and 17 April. The latest sidedressings gave high levels of grain protein. In all t...

Iwainodaichi and Chikugoizumi were given basal NPK fertilizer and 50 kg sidedressed N/ha on one of 10 dates from 5 January to 17 April. Yields of cv. Chikugoizumi were highest with sidedressed nitrogen appl...

Germination and vigour were highest in seeds from the main stem of pla...

Currently, economic, agronomic and environmental concerns, lead to reduce use of herbicides. This reduction can be help by cultural measures like delay of the sowing date. Four sowing dates of winter wheat from 15th of October to 26th of November...
