Response of soil physical properties and onion seed germination to irrigation methods
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 6
Abstract
Mainly, final yield product depends on growth factors such as soil, irrigation and kind of seed. Aggregate collapse and crust formation due to drying prevent germination and reduce the population of vegetation. Greenhouse experiments were conducted to evaluate the effect of irrigation method on physical properties of seedbed and its outcome on the germination and establishment of onion. For this purpose, in 2 soil with different structure (weak and strong), onion cultivated and irrigated with 3 methods (surface flooding, sprinkler and subsurface). Soil physical parameters such as bulk density, saturated hydraulic conductivity and soil penetration resistance, and plant parameters such as mean of emergence date, seedling diameter, fresh and dry yield were measured. Statistical analysis showed that, the irrigation method, soil type, and interaction between them had significant effect on the physical properties and the only factor that affected plant parameters was irrigation method. Because of providing optimal physical conditions in the topsoil, reducing mean of emergence date, increasing diameter, fresh and dry yield, the subsurface irrigation method was selected as the preferred irrigation method.
