Performance of Marsh Seedless cultivar of grapefruit (Citrus paradisi Macf.) on different rootstocks

Indian Journal of Horticulture (1999)

N. K. Mehrotra V. K. Vij Harish Kumar P.S. Aulakh Raghbir Singh

A rootstock trial was conducted on Marsh Seedless cultivar of grapefruit, using Jatti Khatti, Kharna Khatta, Troyer and Carrizo as rootstocks. The results of 20-year trial revealed that the trees budded on Troyer and Carrizo (citranges) rootstocks produced 100% survival with all the trees in healthy condition; whereas Jatti Khatti and Kharna Khatta showed only 50 and 17% survival of the trees respectively. Both the citranges also showed significantly more stock or scion girth and tree volume than Jatti Khatti rootstock. Significanlty more mean fruit yield from 1986–87 to 1996–97 was observed on Troyer and Carrizo rootstocks than on Jatti Khatti. Mean results of fruit-quality attributes showed that TSS percentage was more on Troyer than on Jatti Khatti root-stock. Heavier fruits with less peel percentage were also recorded on Troyer and Carrizo citranges than on Jatti Khatti rootstock.

Wheat Response to Zinc and its Critical Level in Alluvial Soils of Uttar Pradesh

Journal of the Indian Society of Soil Science (1977)

S. C. Agarwala N. K. Mehrotra R.K.S. Rathore

A pot culture experiment was carried out to determine the critical Zn concentration in soils and plants for predicting response to its application. Performance of wheat plants raised on soils of varying Zn status with and without Zn amendment indicated that for alluvial (Gomti) soils of Lucknow district in central Uttar Pradesh, 0.53 ppm neutral N NH4OAc-dithizene extractable Zn represented critical value for avail, soil Zn and at the tillering stage 36 ppm tissue Zn in the middle leaves represented the critical concentration of Zn in wheat var. Kalyansona. In soils low in Zn status, its addition favoured the up$$ of soil P.

Essential Oils as Potent Source of Nematicidal Compounds

Journal of Phytopathology (2000)

Rakesh Pandey Alok Kalra Shishir Tandon N. K. Mehrotra H. N. Singh

Bioassay tests were conducted to find out the nematicidal activity of eight essential oils against Meloidogyne incognita (Kofoid and White) Chitwood at four concentrations. Maximum activity was recorded in oils of Eucalyptus citriodora , Eucalyptus hybrida and Ocimum basilicum followed by Pelargonium graveolens , Cymbopogon martinii, Mentha arvensis, Mentha piperita and Mentha spicata oils, respectively. The eucalyptus ( E. citriodora and E. hybrida ) and Indian basil ( O. basilicum ) oils were highly toxic to M. incognita even at the lower concentrations, namely 500 and 250 ppm. The remaining oils were also toxic to the nematode but at different amounts.

Molecular and intramolecular relaxation in some substituted anilines

Transactions of the Faraday Society (1969)

N. K. Mehrotra T.C. Pant Madhukar Saxena

The present communication reports the relaxation times of 2,4,6-tribromo-, 2,4-dibromo-, 2,4,6-trichloro, 2,4-dichloro, 2,4,6-trimethoxy and 2,4-dimethoxy anilines in dilute solutions of benzene at wavelength 3.13 cm (9585 Mc/sec) in the microwave region. The measurements have been made at 20°, 30° and 40°C, in order to calculate the free energies of activation for the process of dipole orientation and viscous flow. It is concluded that the dipole orientation is contributed by both molecular as well as intramolecular rotations.
