Abstract
Determination was made of the recovery of slurry nitrogen (N), mineral content, fermented quality and nutritional yield of rice based on rate and timing of fermented dairy cow waste application. Rice with V-type leaves was cultivated at higher dosage of N (1.5 or 3 times the normal) using slurry as basal or split at 80 kg N ha^<-1>. The recovery of N ranged from 8.8% to 30.9%, and was higher by split application. The K/(Mg+Ca) equivalent ratio was less than 2.2 subsequent to the milk-ripe growth stage. Fermented quality of rice plant improved with maturity and nutritional value was greater cultivated plots subject to split application. The recovery of N and nutritional yield was thus superior with split application.
