Abstract
Rice root activiators (phthalamic acid (PA) and p-chlorophenyl PA (PCPPA) were tested in pot culture for their effects on yield of IR667-Suwon 214 weak in root activity. The results were as follows: 1) Maximum percentage yield increase was 36.7% with organic matter applied and 13.3% without organic matter in 100 ppm (90ml/0.05
