The increase of crop density has no influence on productive stem formation for pants of Prophet and Kenya varieties, average number of productive stems was 15 units m"Varieties Prophet and Kenya distinguished in respectively 8.4 g and 7.9 g 1000 seed weights in treatment with 200 unit m"2 crop density. No differences were investigated in first and second treatment of BGRC - 30347 equitable number - 1000 seed rate reached on average 6.4 g. Seed weight of Borowski variety decreased gradually with higher crop densities. 1000 seed weight decreased from 7.3 to 6.5 g. It was found that optimum crop density is 100 plants m"2. Yields of all three varieties were highest, compared to other treatments. Analysis of chemical composition of different Crambeabysiinica genotypes showed highest amount of fat in the seeds - 27 percent, and also highest rate of erucic acid - 57, 83 percent in equitable number BRGC - 30347.
The aim of work: Comparison of productivity of different Crambe abyssinica genotypes, investigation of fat composition in the seeds and establishment of optimum sowing rate. Trials were carried out in the experimental station of Aleksandras Stulginskis University in 2011- 2012. Three varieties of abyssinian mustard - Borowski, Prophet and Kenya and one equitable number - BGRC - 30347 were investigated. Plants were seeded in different densities: 100 units m"2, 150 units m"2 and 200 units m"2, in two replications. Plants height, number of productive stems, 1000 seed weight and fat composition in the seeds was determined after harvesting. It was found that lowest height Crambe abyssinica plants, regardless sowing rate were plants of Kenya variety. The heights of other varieties have more depended on sowing rate. The number of productive stems on the equitable number BGRC - 30347 increased gradually in crop densities from 100 to 200 units m"2, respectively average number of productive stems in the plants increased from 15 to 18.4 units. This trend wasn't evident in Borowski variety plants, where highest number of productive stems - 18.1 units m"" was investigated in 150 units m"2 density crop.
