Zlotnikov, K.M. (2005) Application of biostimulant Albit for reduction of nitrates accumulation
and yield increase of lettuce in greenhouses. Gavrish. Nr. 1 p.16-19.
Influence of Albit on lettuce was examined in trials of All-Russia Institute of Vegetable
Selection and Seed Breeding on lettuce varieties Svetlana, Novogodniy, Kucheryavets
gribovskiy, and Moskovskiy parnikovyy both in field (2001-2003) and in
greenhouse (2004) conditions. Independently of the way of lettuce growing, Albit demonstrated
growth stimulating activity on this culture. Averagely, according to results of trials,
treatment with Albit increased yield of lettuce leaves by 230 kg/m²
(12.7% over control).
Besides increase of green biomass yield, Albit increases turgor, improves quality and
marketability, increases average lettuce head weight and content of ascorbic acid in
leaves, decreases content of nitrates, shifts vitamin C/nitrates ratio towards
safe values for human health. Ability of Albit to improve lettuce yield quality
is especially pronounced under greenhouse conditions. In trials on lettuce, effectiveness
of Albit was not inferior to that of standard formulation based on epibrassinolide.
Treatment of lettuce should be performed accordingly to general
application recommendations for vegetables.
