1998
Im I.B. | Beack N.H. National Honam Agricultural Experiment Station, Iksan 570-080 (Korea Republic)
This experiment was conducted to investigate the response of the fertilizer three factors on the growth of Alopeuclus aequalis Sobol. var. amurensis(Kom.) Ohwi. The growth of Alopeuclus aequalis Sobol. var. amurensis(Kom.) Ohwi. such as plant height, tiller number and dry matter production were vigorous on the plot fertilized with phosphate(P, NP, PK, NPK). The main effect of plant height elongation and dry matter production were significant for phosphate and nitrogen, and their interaction effect was recognized, too. Tiller growth and panicle number were mainly affected by phosphate. The growth of Alopeuclus aequalis Sobol. var. amurensis(Kom.) Ohwi. depended mostly on phosphate among the fertilizer three factors. The effect of nitrogen fertilizer was very different according to phosphate fertilizer treatment.
