The main features of the methods used in agriculture should be sustainable, human and animalfriendly and harmless to the environment and natural
resources. Usage of green manure instead of synthetic fertilizers are becoming prominent due to their
eco-friendly effects but allelopathic interactions
among the plants should be used as a criterion to select the effective green manure plants. In the research, germination and seedling growth of some
green manure plants (narbon vetch, forage pea, alfalfa, and soybean) were examined through allelopathy in differently concentrated aqueous leaf extracts
of three different apple cultivars which are chosen
according to their harvest time (Summer Red-Early,
Mondial Gala-Middle, Fuji-Late). The results
showed that increasing concentrations had an inhibitory effect on the growth of green manure plants
prognosticatively but stimulatory effects were also
observed in different concentrations of some cultivars. Mondial Gala (MG) showed a stimulatory effect on germination of alfalfa and soybean but the
slowest germination for soybean (2,97 days) was
recorded at 5 % concentration of the cultivar (MG5). Fuji (F) caused an increment only on the root
growth of soybean and Summer Red (SR)stimulated
the shoot growth of forage pea while it caused a decrement on the root and shoot growth of soybean.
Fresh seedling weight (FSW) of forage pea primarily
increased for all apple cultivars but than, a decrement observed in higher concentrations. SR increased the FSW of soybean but contrarily decreased
the dry seedling weight. If apple gardens were laid
out with SR and MG cultivars, alfalfa and forage pea
could be used as green manure but if the gardens laid
out with Fuji, forage pea, narbon vetch and soybean
could be recommended as green manure plants with
regard to their allelopathic interactions.
