RESEARCHES REGARDING THE PRODUCTIVITY OF OAT-LENTIL INTERCROPPING IN THE ORGANIC AGRICULTURE SYSTEM PUBLISHEDElena Mirela Duşa, Gheorghe Valentin Roman
The paper present a research on the productivity of oat-lentil intercropping, for evaluating his adaptability on natural conditions of South Romania and ecological cultivation. The experiment was carried out in the spring of 2008, in Moara Domneasca Experimental Field, on reddish preluvosoil, in randomized variants, in 4 replications. The seeds used for experiments were ecological. Oat and lentil were sown in alternating rows, in 12.5 cm distance between rows, at a 3-4 cm depth. Oat had a density of 200 seeds/m 2 and lentil of 150 germinable seeds/m 2 . It was determined productivity elements, land equivalent ratio and yields. Average grain yield for oat in monoculture was of 2386.5 kg/ha and in intercropping with lentil was of 1767.5 kg/ha. In monoculture, lentil yield was of 1403.3 kg/ha and in intercropping with oat, it was obtained 780.4 kg/ha. The value of the land equivalent ratio (LER) in the oat-lentil intercropping was 1.29, which means that it is a real advantage of this type of crop system comparatively with oat and lentil raised in monoculture.
