] except buckwheat indicated significant decrease of yield productivity in organic agricul‐
ture compared it with the conventional one. It is generally known that yield productivity is
principally higher in conventional agriculture, because of its industrialization, however, in
some crops we received even double size differences. The productivity of organic spring oats
was acceptably lower by 23.6% compared it with the conventional oats. Hence, the yield
productivity of organic compared it with the conventional winter rye, spring and winter
triticale, spring barley, winter and spring wheat was even lower by 61.6%, 75.2%, 84.1%, 102%,
107.5% and 121% respectively. Just average productivity of buckwheat was higher by 20% in
organic agriculture compared it with the conventional farming (Table 1).

The oilseed rape growing is still a problem in organic agriculture. The confirmation of this
phenomen is three times less average productivity of organic spring rape and two times less
average productivity of organic winter rape compared it with the conventionally grown rapes
(Table 2). However, some Lithuanian organic farmers already are producing the organic
oilseed rape alimentary oil. The leguminous cereals have high importance in agriculture and
especially in organic agriculture because of symbiotic nitrogen fixing bacterium. In this
segment of agricultural crops the average yield productivity was higher in conventional than
in organic agriculture by 21%-36% and in vetch crop even by 137.5% (Table 2).
Organically grown vegetables need more hand work and request new mashinery and growing
technologies, therefore area of organic vegetables are still insignificant (Table 3, Figure 11-15).
Difficulties in growing of organic vegetables are reflected on their average productivity. In
organic agriculture average productivity of total vegetables is even more than two times lower
than in conventional one. The average productivity of organic potatoes in 2011 was 1.5 times
lower compared it to the conventional agriculture (Table 3).
