Studies concerning the yield/M2 of some paprika pepper varieties cultivated in solarium

Abstract

History of pepper culture begins with 3000 – 4000 years ago, in Peru, in the ancient Inca Empire. The fruits
of bell/chilli pepper are consumed at technical or physiological maturity, fresh or processed. Some varieties
with small, sharp and erect fruits are used as ornamental plants. In Europe, the main producing countries are
Spain, Italy, Hungary, Romania and Serbia.
In Romania, pepper was cultivated from the 19th century. The first fruits were set up around Timisoara
(Cenadul Mare, Tomnatic, Lovrin), around year 1923.
The experiment developed during the year 2011, at the Didactic and Research Base of the Faculty of
Horticulture and Forestry, from B.U.A.S.V.M. Timisoara.
The biological material used in the trials was represented by 5 cultivars (hybrids and lines): Délibáb F1,
Sláger F1, Bolero F1, SJD 5 and SJN 5. The experience was set up according to the monofactorial method
with randomised blocks and four replicates.
Hybrid Délibáb obtained the highest yield for the planting scheme 80/40x20 cm, with yield increases between 18% from Bolero and 38% from SJN 5. The yield/m2, registered a gradual decrease by reducing the plant density per row from 20 to 30, 40, 50 cm, to all five genotypes.
