Influence of methods of sowing on productivity and quality of seeds spring rape in the Middle Urals |
|
|
This article presents results of researches about influence of methods of sowing on productivity and biochemical structure of seeds of spring rape of the Russian and German selection. Data are presented in the form of the values average in two years. The greatest productivity has been received at perhaps early sowing time and seeding rate of 1,5 million viable seeds sowed on 1 hectare. Grades reacted to the studied methods of crops equally that is confirmed by the level of productivity and gross collecting fat per 1 hectare. Comparison of a grade Ratnik and hybrid Smilla on biochemical structure of seeds has revealed advantage of the German hybrid on the content of nitrogen, phosphorus and cellulose.
The largest content of fat in seeds is noted at seeding rate 1,5 million/hectare at a grade Ratnik (41,5%) and 2,0 million/hectare at Smill's hybrid (40,4%). Gross collecting fat from 1 hectare was more influenced by productivity size.
