Subject(s): Online resources: In: Journal of Agricultural Research Tanta Univeristy 2004.v.30(3)Summary: Two field experiments were conducted at Sakha Agriculture Research Station Kafr EI-Sheikh Egypt during 2002 and 2003 growing seasons. The aim of this investigation was to study the effect of row spacing (60 and 70 cm.), number of plantslhill (one plantlhill and two plantslhill) and spacing between hills (30 and 40 cm.) on some agronomic traits, yield and its components of six maize crosses i.e. SC10, SC 122, new SC II, TWC 310, TWC 324 and new TWC 327, the results of the combined analysis for the two growing seasons showed the following: -Differences between two seasons were significant for all traits. Mean values for the second season 2003 were higher than the first season 2002 for all traits except silking date. - Spacing between rows had a significant effect on all studied traits except silking date, grain yield and number of rows/ear. The highest mean values were obtained when spacing between rows was 70 cm. apart for all traits except silking date, plant and ear heights. - The number of plants per hill had a significant effect on all traits. The highest values were recorded when one plantlhill was left for all traits except silking date. - All traits were significantly affected by spacing between hills except plant height, grain yield and number of rows lear. The highest mean values were obtained when spacing between hills were 40 em. apart for all traits except silking date and ear height.
