Photosynthetic activity and productivity of potato plants when using foliar dressings with complex micronutrients and humate

The article presents the results of many years research on effect foliar dressing with complex fertilizers and humate photosynthetic activity productivity potato plants Gala Latona varieties. following options have been studied: 1) without treatment (control); 2) Ekorost at a dose 0.2-0.4 l/ha; 3) micronutrient Strada N 3-5 4) R l/ha. was carried out twice during growing season: when full shoots appeared 14 days after first one. Determination leaf area calculation potential were according to VNIIKH method (1967) three times season in phases: budding, flowering, beginning withering away lower leaves. crop harvested by continuous harvesting accounting plots weighing. effectiveness studied agrotechnical methods has proved. best variant investigated ones is use R. this formed more powerful assimilation apparatus had highest potential, which ultimately affected yield tubers. increase two varieties potatoes 21.8-23.1 % relation control. variety turned be responsive action vegetative treatments comparison variety.
