Lodging control through variety choice and management

摘要: Summary Lodged crops are common in most summers and the consequent reductions profit known to be large, yet methods for control poorly understood qualitative. This paper describes how a recently developed model of lodging has been used quantify variety other management factors affect risk. shown that there two types failure mechanism, STEM ROOT lodging, different husbandry practices needed reduce risk each type failure. It is about 50% varieties more prone one form than therefore varietal standing powers should separated stem root lodging. estimated some would differ by as much 3 Stem best reduced avoiding early drilling, high residual N sites delaying spring fertilizer, whereas avoided reducing number plants established rolling consolidate soil. New 5C Cycocel was found equally effective at The quantitative investigation an increase power equivalent sowing weeks, or establishment 100 m -2 (within range 400 200 ), single application Cycocel.
