| Research Abstract |
It was studied on avoidance of lodging of paddy rice "Koshihikari" for rate of nitrogen ferilizer application.Especially it was compared rice growth on basal applocation nitrogen zero with 6kg per 10a,and responce for some silicate slags (fertilizer) with basal application on rice yield also was compared. Main result by field experiment was as follows.
For avoidance of lodging decreace to about 2kg/10a at the rate of basal nitrogen fertilizer application is desirable on well dained pakky field of sandy 10am or 10am,and the greater part of nitrogen application is desirable by topdressing.
Basal application with silicate slags fertilizer or dressing hill soil from the Teriary is available to rice plant with strong stem and high yield.
