Abstract
Field evaluation of subsoiling and liquid fertilizer injection under minimum tillage practice of sugarcane planter has been tested. This experiment has been conducted at the field of National Agricultural Machinery Center (NAMC), Kasetsart University and Flying Training School, RTAF, Khampaengsaen in 2010. The seeding of the field performance was done with three models of sugarcane planter including a conventional sugarcane planter (CP), subsoiling sugarcane planter (SP) and combination of subsoiling with liquid fertilizer injection sugarcane planter (SFIP). Significant of the three different models of the sugarcane planter, soil types and seeding depths has been discussed. Comparative study on this experiment under rain-fed condition found that the significant of soil types and different models of sugarcane planter were found in the germination percentage under this specific field trial. These come from the fact that subsoiling and liquid fertilizer injection can improve areration, infiltration, drainage rate, the moisture in soil and subsoil improvement lead to increase the germination of seeding under minimum tillage practice.
