Abstract

Field experiments were conducted to determine the optimum application rate of sunn hemp Crotalaria juncea leaf residue in the management of Meloidogyne incognita on tomato. Sunn hemp applied at rates of 0 (control), 2, 4 and 6 kg/ha showed a varied effect on second stage juveniles of M. incognita. There were no differences in plant height and stem girth. The 6 kg/ha treatment reduced the M. incognita population by 94% compared with the control. The highest yield of tomato (168.7 kg/ha) was recorded in 6 kg/ha treatment of sunn hemp.
