Abstract

This study was conducted to investigate the effect of Polyacrylamide (PAM) on the seedling stage growth of cereal crops, soybean, maize, and barley, which are widely grown in reclaimed agricultural lands. A series of experiments were carried out using five different PAM products (A, B, C, D, E) and their various concentrations (10, 20, 30, 50, 100 mg L-1). The standardized soil pots were filled with soils collected from reclaimed lands (soybean, maize: 250 g, barley: 150 g), and three crops were planted. Each PAM solutions with different concentrations were sprayed onto the soil surface of 1.0 mm thickness. After initial full irrigation, timely-dependent amount of water was irrigated to maintain the total weight of the pots. Cereal crops were cultivated for 21 days and then compared their plant lengths and fresh weights to assess the effect of PAM. Plant lengths and weights from untreated and PAM-treated pots were not significantly different (a = 0.05). In addition, different PAM products did not also show any effects on crop growth. However, plant lengths and weights of soybean and barley from the experimental plots with different PAM concentrations showed their differences in certain levels (a = 0.05), which indicating the possibility of growth effect with PAM treatment.
