Plant Growth Enhancement Techniques

Abstract Experiments were conducted in 1979 and 1980 to evaluate anticrustant (H 3 PO 4 and Nalco 2190) effects on stand establishment, growth, and yield of chile pepper ( Capsicum annuum L.). While plant stands and fruit yield were not increased by applying H 3 PO 4 over the seeded row in 1979, hypocotyl stress of germinants was reduced. Stands and P content in 1980 were not increased by H 3 PO 4 or Nalco 2190 treatments 1 month after emergence, but plant height was increased significantly by both anticrustants. Yields of fresh green chile peppers were not enhanced by treatments. While germinant stress could be reduced by using anticrustants, it was concluded that a factor other than crusting was limiting chile seedling growth in southern New Mexico.
