POTATO YIELD INCREASE METHOD Russian patent published in 2008 - IPC A01C1/00 A01N61/00 A01N63/00 A01N65/00 

FIELD: agriculture.

SUBSTANCE: potato tubers are greensprouted at light during 20-25 days, at a constant temperature of +12÷14°C. After the greensprouting a solution with the following composition is applied to the tuber surface while mixing tubers vigorously: fundasol (WP) at a rate of 1.0 kg/t, Gumi-30 (flowable paste) at a rate of 0.6 kg/t, and arachidonic acid (EC) (Immunocitofit, 5 l/ha) at a rate of 2 ml/t of tubers. Treated tubers are sown no later than 2 days after the treatment. During the potato vegetation period two-fold vegetation treatment of the plants is carried out while fighting the Colorado beetle, using Gumi-30 at a rate of 0.3 kg/ha or 2.5% bischofite solution of the initial brine, at a consumption rate of 300-400 l/ha of the working solution.

EFFECT: yield increase up to 23-29%; enhances product quality; accelerates commercial tuber ripening from 5 to 7 days and decreases pesticide load on agrocenosis.
