Abstract
Rice grains of the studied cultivar (Giza 178) and (Egyptian Hybrid 1) were obtained from Agricultural Cooperation Rice Research section Agricultural Research station, El-Gemmiza, Gharbia Governorate.
1. Yield and its components:
1.1- Effect of cultivars:
As seems to appear from obtained data, the two tested cultivars significantly differed in all studied characters in both seasons. Egyptian Hybrid 1 rice cultivar significantly produced the highest number of tillers /m², number of panicles /m², Plant height (cm), panicle length (cm), number of total grains/ panicle, number of filled grains /panicle, 1000- grain weight, grain yield (t/fed) and Straw yield (t/fed). While Giza 178 rice cultivar produced the lowest values in both seasons.
1.2- Effect of seedling age:
The statistical analysis of obtained results manifested that seedling age had a significant effect on all studied characters in both seasons. The highest values of these traits were produced when using the youngest seedling 15 day old. On the other hand the oldest seedling age 25 day old gave the lowest values of these traits.
1.3- Effect of transplanting spaces:
Transplanting spaces exhibited significant effect on all traits study in both seasons. The highest values of these traits were produced when using the widest spacing between hills (30×30 cm) in both seasons. While the lowest values were obtained when using the closest spacing between hills (20×20 cm).
