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 (5.4 USD)/hectare. Economical efficiency of 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 (retail price is 88-100 USD) 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.
