Establishment of Some Technological Sequences for Medium-Long Fruit Cucumbers Cultivated in Greenhouses

摘要

In the experiment effectuated in 2007, at the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, in a “Venlo” type greenhouse, the plant density and fructification managing on half long fruit cucumbers yield were studied. Observations regarding early and total yield as well as fruit commercial quality have been done. In the experience was used Alamir F1, a cucumber hybrid produced by Dutch Nunhems company. A bifactorial experience was organized: Factor A – plant density with 2 graduations: a1 – 16000 plants/ha; a2 – 24000 plants/ha; and Factor B – fructification managing with 2 graduations: b1 – fructification on main steam; b2 – fructification on main steam and on fruit bearing springs. Variants with 24000 plants/ha density recorded yield increases about 52.4% for early yield and 44.3% for total yield comparative with variants with 16000 plants/ha density
