    Bare-root dip of brinjal seedlings in phytochemicals for the management of root-knot nematode (Meloidogyne Incognita)
    (Kerala Agricultural University, 2000) Asha John; Hebsy Bai
    Aqueous ncem leaf extract, neem oil and marotti oil at different concentrations were tested as bare-root dip treatments for their efficacy in containing root-knot nematode [Meloidogyne incognita (Kofoid and White, 1919) Chitwood, 1949] infestation in brinjal. Root-dip in neem leaf extract for 1 h resulted in significantly better height and number of leaves in the treated plants than neem oil and marotti oil. Among the different concentrations of nccm leaf extract tested, 6.25 and 25 per cent extracts proved more effective. Significant reduction in gall index was also seen in neem leaf extract treated plants. Higher concentrations of the extract (50 and 25 per cent) significantly reduced the number of egg masses produced. But none of the phytochemicals had any adverse effect on the hatching of the egg masses. All the three phytochemicals irrespective of the doses reduced population of the nematode in the soil. An overall assessment of the result established the superiority of neem leaf extract (25%) among the different phytochemicals in checking nematode infestation.

    Evaluation of brinjal varieties for yield and resistance to bacterial wilt (Ralstonia solan acearum)
    (Kerala Agricultural University, 2000) Gopalakrishnan, T R; Sally, K Mathew; Singh, P K; Peter, K V
    Comparative performance of brinjal varieties and lines over five years revealed the superiority of SM-141 (Haritha) in terms of yield, quality and resistance to bacterial wilt (Ralstonia solanacearum). This culture produces long, light green and glossy cylindrical fruits, with a mean wilt incidence of 9.38 per cent. SM-141 has non-prickly stem and leaves with white flowers and has a mean productivity of 13.5 t ha"1. Considering its performance in the research stations and in farmers' fields, SM-141 has been released as Haritha for the State of Kerala

    Two new wilt resistant f1 Hybrids in brinjal (Solanvm melongena L.)
    (Kerala Agricultural University, 2000) Gopalakrishnan, T R; Narayanan Kutty, C; Singh, P K
    Ten wilt resistant and divergent genotypes of brinjal (five purple fruited and five light green / white fruited) were crossed separately and the resulting eight Fj hybrids were evaluated for their performance in a bacterial wilt sick plot at Vellanikkara, Trichur. All the F, hybrids showed high yield potential with resistance to wilt. Based on over all superiority in terms of yield, consumer acceptability and resistance to wilt, two purple fruited hybrids viz., Surya x SM-116 (purple, round to oval) and Arka Keshav x SM-71 (purple, long) were selected and evaluated further for two more seasons. Both the hybrids were resistant to wilt and had a yield potential of 91.31 and 89.07 t ha"1 respectively.
