Description
This study was conducted to determine the effect of planting density on silage corn production and silage quality. Dent corn cv. Pioneer 3424 was planted at different or the same densities by changing row width or intrarow spacing or the both. The dry matter yield and silage quality were determined at different stages of ripening and the results are summarized as follows: When intrarow spacing was changed (under different intrarow spacings), the rate of increase of dry matter per plant was high at the low and intermediate planting densities and the dry matter yield per 10 are was high at the intermadiate planting density. When both the row width and intrarow spacing were changed to give different densities, the dry matter yield at the yellow-ripe stage was definitely high at the intermediate density. The ratio of ear dry matter to total dry matter observed at the intermediate planting density was essentially the same to that obtained at low planting density when the densities were adjusted by changing the intrarow spacing. The silage quality was excellent in most cases irrespective of planting densities. The digestible crude protein (DCP) and total digestible nutrients (TDN) were significantly lower at the high planting density than those at other densities. Both the DCP and TDN yields per 10 are were higher at low and intermediate densities. TDN yield was highest when planted at a 80 X 15 cm density. These results indicate that, when planting densities were adjusted by changing the row width and/or intrarow spacing, low and intermediate planting densities were favorable for silage corn to produce higher dry matter and nutritional quality.
