Productivity and quality of seeds of the alfalfa variety ‘Gyuzel’
Abstract
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.
