The trials trying to create optimal feed regime for fruit formation of the new variety ‘Gyuzel’ have been carried out on a grey forest, heavy loamy granulometric soil of Predkamie Area of the Republic of Tatarstan with a deficit of balance of exchangeable potassium (35%). The soil of the experimental plot is characterized with such agrochemical indexes as humus content of 2.6-2.8%; the sum of absorbed basis of 33.6-35.7 mg per 100g of soil; phosphorus content of 129-131 mg; exchangeable potassium content of 86-90 mg per 1 kg of soil (according to Tyurin); pH of salinity of 5.4-5.8. There has been determined a positive effect of root top-dressing on general growth of alfalfa, on formation of generative organs, on seed productivity of variegated alfalfa variety ‘Gyuzel’. The increase of seed productivity was a result of the increase of beans on alfalfa inflorescences and an amount of well-developed seeds compared with an amount of bad-developed and hollow seeds.
