Abstract
A field experiment was carried out at the Rice Research Station in Al-Mishkab during 2008 and 2009 seasons to study the effect of transplanting space on yield of three rice varieties. A split plot in RCBD with four replicate was used . Varieties (Anber 33, Yasmine, and Fourat-1) were assignad in the main plots, while transplanting spaces (20×10), (20×15), (25×10), (25×15), (30×10) and(30×15) cm occupied the sub- plots. The results showed that the wide transplanting space (30×15) cm population of (22.2) hill.m-2 gave highest number of panicles.hill-1, number of grains. Panicle-1, weight of 1000 grains and paddy yield.hill-1. While the narrow transplanting space (20×10) cm population of (50) hill,m-2 gave significant increments in the number of panicles.m-2. The ather two transplanting spaces (30×10)and (20×15) cm which attained population (33.3) hill.m-2 were superior in the paddy yield.m-2,because they gave the best combine of wide and narrow spaces as they gave the highest paddy yield.hill-1, high number for panicles.hill-1 and panicle.m-2, grains. panicle-1and less sterility percentage. This means that the highest paddy yield in the hill of wide transplanting space will not compensate the decreae in number of plants.m-2. Cultivars showed significant differences in most studied characters. Fourat1 was superior paddy yield but not significant differences with Yasmine due to its highest number of panicles.hill-1 and panicles.m-2, weight of 1000 grains and paddy yield.hill-1 .
