Comparative study of body composition of four fish species in relation to pond depth
Abstract Fish specimen of Labeo rohita, Cirrhinus mrigala, Hypophthalmicthys molitrix and Catla catla were sampled from three ponds of different depths (152 cm, 122 cm and 76 cm) to compare the body composition of these species in relation to ...

Environmental monitoring of economically important invertebrate pests in Bramley apple orchards in Northern Ireland
Abstract: Apple orchards are host to many species of both pest and beneficial invertebrates. Many of the pest species can cause severe economic damage if populations are left unchecked. Within Northern Irish Bramley apple orchards only four species ...

Effect of exo-polysaccharides producing bacterial inoculation on growth of roots of wheat (Triticum aestivum L.) plants grown in a salt-affected soil
Abstract: Effect of soil salinity on physico-chemical and biological properties renders the salt-affected soils unsuitable for soil microbial processes and growth of the crop plants. Soil aggregation around roots of the plants is a function of the ...

Effect of aluminum and chromium on the germination and growth of two Vigna species
Abstract: The study deals with the effect of metal toxicity (aluminum, chromium and combination of both the metals) on seed germination, root length, shoot length, seedling length and dry biomass of Vigna radiata and V. sinensis. Chromium adversely ...

Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system
Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds ...

Germination and seedling growth of corn (Zea mays l.) under varying levels of copper and zinc
The heavy metal tolerance in corn (Zea mays L.) var. ‘Neelum’ was assessed at germination and seedling growth after having subjected it to different concentrations of CuSO4 and ZnSO4. Germination was not affected by any of the metal tested, whereas ...

European red spider mite - an environmental consequence of persistent chemical pesticide application
The European red spider mite, Panonychus ulmi, is a major pest in almost all fruit growing regions of the world (Hardman et al., 1985). Spread of P. ulmi to most apple-growing areas has probably been caused by the distribution of nursery stock ...

Spatial pattern of variation in populations of Acacia nilotica in semi-arid environment
Variability among populations was analyzed in five provenances of Acacia nilotica from spatially variable habitats. Populations of A. nilotica developed in response to their habitat conditions. The level of variability was significantly high among ...
