ABSTRACT
Root-knot nematodes cause significant yield losses in tobacco (Nicotiana tabacum). Their management is essential for the grower to maximize production. Nematodes migrate up and down the soil profile in response to host availability. The objective of the study was to evaluate the effect of tobacco rotations on the spatial and temporal distribution of nematodes. Sampling was done every month from September 2010 to April 2011. The experimental design was a split-plot in a randomized complete block design. The main plot factor was fumigation and subplot factor was rotation. The rotations were sugar beans- tobacco, sunn hemp- tobacco, winter katambora - tobacco (all winter crops) and a fallow –tobacco. In each of the 8 treatments sampling was done at three different positions. At each sampling position sampling was done to a depth of 45cm at intervals of, (0-15 cm), (15-30 cm), (30-45 cm). Data was transformed and analysis of variance ANOVA was done using the statistical package Genstat (Version 7.22). No interactions were found between fumigation and rotations in all three depths (p>0.05). Significant differences (p
