Adverse effect of root-knot nematode, Meloidogyne incognita on spinach beet Beta vulgaris bengalensis and fenugreek, Trigonella foenum graecum
Abstract
Root-knot nematode Meloidogyne incognita revealed its significant adverse effect on seed germination and seedling emergence of spinach beet at 500 J2/kg soil in both sterilized as well as in unsterilized soil. However, in fenugreek the significant inhibition of germination started at 500 J2/kg sod in both the soils but seedling emergence was inhibited at 1000 J,lkg soil in unsterilized soil while in sterilized soil it was at 500 J2/kg soil. The significant reduction in plant growth characters of spinach beet and fenugreek was revealed at 500 J2/kg soil and above levels. There was increase in number of galls and total nematode population with increase in inoculum level from 50 to 5000 nematodeslkg soil.
