| dc.description.abstract | Lupinus is a diverse genus in the legume family (Fabaceae).Its common name used in Europe and Australia lupin for both native and domesticated species, while the common name for native Lupinus in North America is lupine.Taxonomically,lupins are classified within the order fabales,family Fabaceae,trible Geniseae and genus lupinus and the number of species in this genus is expected to be over 1000.However ,the commonly agreed number of the existing lupin species is around 280. The present study was undertaken to evaluate the effects of compost on growth and yield of L. albus in pot experiment. A total of 100 plastic bags (depth 20cm, diameter 10 cm) were filled using, 50 bags contained 1kg of vertisol, and 50 contained soils mixed with compost. The study found out that vertisol mixed with compost at rates of 120 quintal ha improved the vegetative growth of L.albus by 51% and yield increased by68 . In contrast, no significant difference in seed germination (p < 0.05) was observed between the two treatments for all the germination parameters measured. In particular, differences in mean germination time and germination vigor were not significant between seeds germinated in vertisol mixed with compost (VR+Comp) or in vertisol only. Maximum mean plant height (cm), internodes length (cm), branches/plant, leaf number, leaf area (mm2), root collar diameter (RCD) (cm), number of capitulae/plant, number of seeds, 1000 seeds weight (gm) and total dry weight (gm) were41.5, 11.9, 7, 26, 43.2, 1.3, 8, 164, 0.5, 2.2, and 1.9, respectively, for plants grown in VR+comp.The corresponding measurements for the control plants were25, 5.3, 3.0, 19.2, 26.2, 1.2, 4, 90, 0.3, 1.8, and 1.2, respectively. Based on the results obtained it is concluded that application of compost significantly (p< 0.01) improved almost all the growth and yield components of L. albus. | en_US |
