ABSTRACT:A vermicomposting study was conducted with different organic waste like wheat straw, cotton stubble waste and leaf litter by using five species of earthworms i.e. Eisenia foetida, Eudrilus eugeniae, Perionyx excavatus, Lampito mauritii and one local. Lowest C:N ratio was recorded in cotton waste inoculated with Eisenia foetida over all other combinations except cotton waste inoculated with Lampito mauritii and leaf litter inoculated with Eisenia foetida and Lampito mauritii.

Key words: Earthworm, C:N ratio.

ABSTRACT:The success of soil management to maintain soil quality depends on an understanding of how soils respond to agricultural use and practices over time. As a result, the important soil quality indicators were assessed under different land use systems to provide base line data for future research in Southeastern Adamawa State, Nigeria. The different land use systems were the cultivated land, natural fallow land, Gmelina plantation, pasture and the undisturbed natural forest land. One soil profile was opened in each land use system for field descriptions and laboratory studies in 2012/2013. The soil physical properties such as structure, colour, particle size distribution and soil depth characteristics showed notable variations due to different land use system, particularly in the surface horizons.

ABSTRACT: Field experiment was conducted to compare between the wheat grains produced from plants sprayed by 1% solution of irradiated Na- alginate )ISA) stored in refrigerator for 30 months with those planted recently on vitality, quality and resistance to injury by Rhyzopertha dominica invasion. It was observed that untreated stored grains T1 decreased germination percentage about 15% comparing by newly planted control (T) and the depress in the stored treated grains were 7, 2 & 3% in 80 (T2), 120 (T3), and 160 (T4) kGy, respectively.
