Introduction
The history of long term experiments began in 1843, when John Lawes, the owner of a fertilizer factory, together
with Henry Gilbert started doing research on the influence of fertilizers on plant growth. They conducted the first
long-term experiment with fertilizers, laid the groundwork for modern scientific agriculture, set the principles of
crop plants nutrition and founded Rothamstead Research. In Romania the first long-term experiments were
conducted by C. Hera and Z. Borlan in 1966, at ICCPT Fundulea, on cambic chernozem.
In time, researchers proved the favourable effects of crop rotation (Ciontu et al., 2010; Ciontu et al., 2011),
whereas Budoi and Penescu (1996) stated that “crop rotation is the only agrotechnical measure with no material
costs, it only requires that the farmer possesses skills”.
The present paper assesses the financial efficiency when applying rotation and fertilization, in the Crop Rotation
Field at Moara Domneasca Experimental Farm, which was founded in 1981.
