The effect of potassium humate and micronutrients on the yield of cucumber fruits in greenhouse conditions

A hybrid Svyatogor F1 of Dutch breeding was grown in a winter greenhouse for three turns. Studies have shown that pre-sowing seed soaking treatment and foliar top dressing plants with potassium humate did not affect germination, but positively affected plant growth, except lithium carbon dioxide. For PABA, the leaf area increased, while it decreased. Micro fertilizers, lithium, had positive effect on formation fruits, their weight yield. The largest yield cucumbers obtained by PABA mixed other trace elements: 33.63 34.0 kg/m 2 control indicator 30.75 . One foliage fertilization micro fertilizers also effect: terms yield, variant mixture all first place - 34.75, 33.93 second place, 30.97 were control. Lithium retarding indicators.
