Effect of environment friendly polymers on the growth development and yield of Piper Nigrum in Chuse, Gialai province

Abstract

Effect of superabsorbent (AMS-1) and erosion control (PAM) polymers on the growth, development and yield of Piper nigmm tree was studied at Chu Se, Gia Lai province in 2012. The result showed that AMS-1 and PAM having positive impact on the growth and development OĨ Piper nigrum tree. AMS-1 and PAM at CT-AMS-PAM-Tieu and CT AMS-Tieu treatments provided plants with better growth and higher yield than control and other treatments.
