Influence of Albit on cucumbers was examined in 4 field trials in 2 regions of Russia
(Moscow and Leningrad oblasts). Trials were performed in 2001-2003 on the following
cucumber varieties: Izyashchnyy, Elektron, Marinda, and Zozulya
by All-Russia Institute of Vegetable Selection and Seed Breeding and Leningrad Regional
Plant Protection Station. High efficiency of application of Albit on cucumbers was also
proven in farms of Krasnodar krai and Saratov oblast and in small private plots all
Averagely, according to average results of all performed trials, treatment with Albit
increased the yield of cucumbers by 116.6 centners/hectare (24.0%).
Depending on region and year, yield increase over control varies from 50 to 270
centners/hectare (0.5-2.7 kg/m2). Besides yield increase, Albit increased
germination of cucumber seeds, number of pistillate flowers, turgor of cucumbers;
improves drought resistance and decreases content of nitrates. In the conducted
field trials economical or biological effectiveness of Albit was not inferior to that
of standard formulations based on Pseudomonas aureofaciens and epibrassinolide.
Treatment of cucumber plants should be performed in
accordance with general application recommendations for vegetables.
Full treatment cycle (presowing seed treatment + two foliar sprayings) takes
61 ml of Albit per hectare; it costs about 135 roubles/hectare (based on
all trials conducted in Russia in 2001-2006: to calculate equivalents in
Euros, please use 2004 exchange rate of 1 Euro = 35 Rubles). Economical
Albit on cucumbers as well as on other vegetables is extremely high. According
to available data of field trials (the minimal yield increase is 50 centners/hectare),
each litre of Albit is able to provide not less than 820 centners
of additional yield. Possibly, ability of Albit to increase yield of cucumbers
is overestimated (due to small number of trials), but anyway, the fact of considerable
cucumber yield increase due to application of Albit is undoubted.
