Investigation of nitrogen fertilizer requirement of pearl grass (Axonopus Compressus (Sw.) P. Beauv.)
In this study, three concentrations of N (0 ppm, 25 ppm and 50 ppm) were applied on A. compressus (Pearl grass) to investigate which one is suitable to support the grass to grow well. The experiment was arranged following a randomized complete design of five replicates per treatment. The N was appli...

| Summary: | In this study, three concentrations of N (0 ppm, 25 ppm and 50 ppm) were applied on A. compressus (Pearl grass) to investigate which one is suitable to support the grass to grow well. The experiment was arranged following a randomized complete design of five replicates per treatment. The N was applied every two weeks after grass planting. Pearl grass under 25 ppm and 50 ppm N application were found to be closely similar in term of dry matter (16.92 g vs. 22.57 g), leaf surface area (5.14 sg. cm vs. 5.05 sg.cm), root length (34.62 cm vs. 35.92 cm), stolon length (11.72 cm vs. 12.23 cm), shoot density (37 shoots/sg. cm vs. 37.4 shoots/sg. cm), coverage (75.67% vs. 89.10%) and colour canopy (108.98 hue vs. 105.50 hue). Hence, 25 ppm was suggested as the suitable N application to support the grass to grow well at least when planted in trays. This suggestion was proposed partly because of the lower cost to use lower concentration of N. |
