Root-knot nematodes are believed to be amongst the biological constraints causing severe damage and a great reduction in the productivity of okra. The purpose of this study was to apply organic matter and non-symbiotic nitrogen-fixing bacteria to minimize the addition of chemical fertilizers that constantly pollute the environment. Experimental stu...

The latex bearing botanicals of Nerium indicum, Thevetia peruviana, Calotropis procera, Euphorbia hirta were assessed for their efficacious nature against plant-parasitic nematodes and soil-inhabiting fungi infesting chickpea Cicer arietinum (L.) and also on the succeeding crop, okra Abelmoschus esculentus (L.) Moench. in field condition in terms o...

A field experiment was conducted during 2009-2011 at the Aligarh Muslim University Agricultural Research Farm, India, to evaluate the efficacious nature of some oil-seed cakes such as neem cake and castor cake, a botanical Calotropis procera and phosphate solubilizing bacteria (PSB) Pseudomonas fluorescens singly and in various combinations, on the...

Soil application of organics has been explored as an alternative means of organic management of plant-parasitic nematodes. Efficiency of different oil-seed cakes of neem (Azadirachta indica), castor (Ricinus communis), groundnut (Arachis hypogaea), linseed (Linum usitatissimum), sunflower (Helianthus annuus) and soybean (Glycine max) were evaluated...

An experiment was conducted during 2007-09 to eplore addition of organic matters and phosphate-salubilizing bacteria (PSB) to soil as an alternative means of organic management of nematodes under field condition at Aligarh, Uttar Pradesh. Organic matters in the form of oilseed cakes of neem (Azadirachta indica Adr. Juss.), castor (Ricinus communis...

A field experiment was conducted during 2009-2011 at the University Agricultural Research Farm to evaluate the efficacious nature of some botanicals such as Argemone mexicana, Calotropis procera, Solanum xanthocarpum, and Eichhornia echinulata in combination with normal as well as deep ploughing against plant-parasitic nematodes and soil-inhabiting...

Efficacy of some botanicals such as Calotropis procera, Calotropis gigantia, Thevatia peruviana, Euphorbia neriifolia, Argemone mexicana, Solanum xanthocarpum, Eichhornia echinulata, Nerium indicum and Pedilanthus tithymoides were evaluated against root-knot nematode, Meloidogyne incognita under field conditions. Significant reduction was observed...

Plants can be used to remove heavy metal from the environment and hence reduce the toxic effect of heavy metal on health of all living organism. Cadmium is a non-essential heavy metal that does not have any metabolic use and can be harmful even at low concentrations. Fenugreek (Trigonella foenum-graecum L.) and Blackgram (Vigna mungo L.) are two im...

The addition of organic matters to soil has been explored as an alternative means of nematode control under field conditions. Several oil-seed cakes of neem (Azadirachta indica), castor (Ricinus communis), groundnut (Arachis hypogeae), linseed (Linum usitatissimum) and sunflower (Helianthus annuus) were found to be highly effective in reducing the...

Leaf extracts of two latex-bearing plants such as Calotropis procera and Thevetia peruviana were used as bare-root dip treatment for the management of phytonematodes, Meloidogyne incognita and Rotylenchulus reniformis infecting tomato (Lycopersicon esculentum) and eggplant (Solanum melongena) plants. Significant reduction was observed in the root-k...

Different concentrations, viz. 5, 10 and 25 ppm of aldicarb, carbofuran, phorate fensulfothion and fenamiphos were observed for their pesticidal effects on chickpea plant in terms of various plant growth parameters such as plant length as well as weight, pod numbers, root-nodulations and chlorophyl content. Significant improvement in plant growth w...

Fly ash emanating from the thermal power plant, Kasimpur, India, influenced various physicochemical properties of the soil, which were found favourable to the plant-growth parameters such as plant length, fresh as well as dry weights, net primary productivity, leaf area and photosynthetic pigments of bottlegourd and subsequently checking the root-r...
