Organic amendments for the management of Meloidogyne incognita in tuberose

Abstract

The efficacy of three oil seed cakes viz., neem, castor and mahua were evaluated against root knot nematode, Meloidogyne incognita in tuberose under glass house conditions. There was a significant increase in plant growth and decrease in root knot damage in all the treatments compared to control. Among the treatments combination of neem cake with carbofuran recorded the highest flower yield (5.4g) with maximum reduction in nematode population (78 nematodes / 200 cc soil). The next best treatment was mahua with carbofuran (114 nematodes / 200 cc soil) for the management of M. incognita and improved the flower yield (4.6g) of tuberose.
