Abstract


Field studies were conducted to investigate the effect of a plant growth promoting rhizobacterium, Pseudomonas fluorescens, neem cake, mustard intercrop and carbofuran 3 G, in different combinations, on potato cyst nematodes, Globodera rostochiensis and G. pallida, and yield of two potato cultivars viz., Kufri Jyoti and Kufri Giriraj. Higher tuber yields and lower nematode densities, in terms of number of females/2.5 cm root and number of eggs/g soil, were recorded for the cultivar Kufri Giriraj. In both of the cultivars, an application of P. fluorescens + neem cake + mustard intercrop + carbofuran 3 G increased the yield and reduced the potato cyst nematode population the most, followed by the application of P. fluorescens + neem cake + mustard intercrop, which was almost equally effective.
