Bugawa game da binciken lalata gidaje ya nuna isa skinset ya dogara da wasu dalilai

Ba za ku iya amfani da abin da ke faruwa a ƙasa ba a matsayin jagora ga abin da ke faruwa a ƙasa, bisa ga sabon bincike game da madadin masu lalata.

A key finding from the work is that the rate of foliage desiccation does not correlate well with that of skinset, the key to harvesting without damage. The discovery was among the key findings of a project examining the best alternative desiccants to diquat, carried out by NIAB CUF on behalf of AHDB. The research focused on the ‘hard to stop’ situations such as indeterminate varieties and seed crops.

Previous AHDB sponsored work by NIAB CUF has suggested that reducing the nitrogen rate can make desiccation easier. Dr Stalham will run further tests this year to develop a quick, quantitative, method to assess skinset in the field.

AHDB will host webinars later this year looking at in-field haulm aikace-aikacen lalata a ranar 19 ga Agusta, sannan wani a cikin filin haulm illar lalacewa akan 16 ga Satumba.
