Farm results yield

Conventional breeders often think that organic farmers require an absolute disease resistance, but in many cases tolerance or partial resistance can be sufficient. Organic farmers are used to searching for ways to reduce risks by an array of solutions at different levels (farm, crop, variety) and also adopt such a strategy in their search for appropriate combinations of supporting variety characteristics. There are different variety characteristics that support yield and yield stability through optimal plant health (Table 5.2). Plant health can be defined as a result of the following components ... 

A general picture emerges of lower yields and productivity per farm, lower input costs and higher output prices on organic farms than those on conventional comparisons. The results in the different studies included in Lampkin and Padel (1994) ranged from lower net returns in the studies in the USA, UK and Switzerland, similar in Australia and higher in studies from Germany, Denmark and Wales.
