Abstract
The response of three flax genotype, i.e. Sakha 1 , strain 402112 and strain 399121113 to nitrogen fertilizer levels (45,67.5 and 90 kg nitrogen 1 faddan ) ., blofertilizer and compost were studied concerning growth, groW'r.h analys s as well as physiological growth parameters of flax plants .
Experiment was conducted at Ismalla AgrIc. Res. Station season 1998 11999 and 1999 1 2000 to study effect of biofertiIizer inoculation ( Biofertan ) as N2 fixers bacteria and VAM fungi and organic manure ( compost) on growth and growth parameters of flax genotypes compared with three levels of nitrogen fertiliZer. Growth measurements were recorded at 60,90,120 days after sowing. The resu ts revealed that plant height, number of leaves 1 plant and dray weight for man of growth parameters continued to increase until the last sampling dates. Flax genotypes showed significant effect on growth attributes i.e. leaves area, leaves weight, stem weight and number of leaves per plant to the age of plant and growth characters of genotype.
Sakha 1 superiority the strain 402/12 and 399/21113 in crop growth rate (C.G.R.), relative growth rate (R.G.R.) and Net assimilation rate (N.A.R.) . Biofertan exceed organic matter in most of growth attributes. The highest relative fontribution for yield was obtained from plant height and root weight 34.2 and 13.2% re pectively.
The highest positively and significantly correlated between plant height and most of growth characters were obtained from Sakha 1 for straw yield. On the other hand there was appositive and significant correlated in strain 402112 betwe n weight of fruiting zone and most of growth attributes for seed yield. It mean that sakha 1 tend to be dual purpose and strain 402/12 type seed.
This results are of great interest to increase seed and straw yield 1 fad through selectioll 01 the 'Yield character which have large direct effect of both three genotypes under study using biofertliZer as well as the indirect effects through the attributes that have big indirect in flax genotypes under study.
