EFFECT OF Fusarium solani, Rhizobium leguminosarum, BENOMYL AND NITROGEN FERTILIZATION ON CERTAIN CHARACTERS OF LENTIL

Abstract

The effect of seed inoculation with Rhizobium leguminosarum, Biavar viciae, seed treatment with benomyl, nitrogen fertilization and Fusarium solani (Mart.)Synder et Hansen on three lentil (Lens culinaris medic) cultivars were studied. In the presence of mixed inoculum (3 isolates) of the pathogen, the lentil cultivar IPA-98 was more resistant than IPA-2000 and Barka. It was superior into response to inoculation with a mixture of three races of R. leguminosarum and nitrogen fertilization in addition to into high production. Nitrogen fertilization decreased severity and improved plant growth, including production of three lentil cultivars, lentil yield and number of root nodules were increased when seeds were inoculated with R. leguminosarum. Yield increase and improvement of studied characters were recorded in the treatment which involved nitrogen fertilization, seed dusting with benomyl and inoculation with Rhizobium bacteria. This study constitutes the first of its kind, in which the effect of these factors on three cultivars was recorded in Iraq.
