EFFECT OF HARVESTING TIME ON MILLING YIELD AND GRAIN BREAKAGE FOR EGYPTIAN PADDY RICE

The effect of harvesting time on rice sensory and physio-chemical properties not well understood. Timing of harvesting rice with meteorological conditions can allow growers to gain more for high head rice yield. Three of Egyptian varieties Sakha 106, Giza 179 and Hybrid1 were grown during 2015 to estimate the total milling yield and grain breakage at five different harvest times {22, 25, 28, 31 and 34 days after 50% of flowering (DAF)}.It was concluded that the highest total milling yield and lowest grain breakage was obtained at the 28, 25 and 31 day after 50% of the flowering for Sakha 106, Giza 179 and Hybrid1 respectively. So harvest management preserves rice quality that contribute directly to profit, and then rice growers must harvest rice as carefully as they grow it. Although this study showed that harvesting time is very important, there are many factors have effect on milling quality. Among of these that were investigated is the harvesting time.
