Abstract
The field experiments were conducted at The Experimental Farm of Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt during 2018 and 2019 seasons to investigate the effect of harvest time on grain yield and its attributes as well as grain quality characteristics of some rice cultivars at different storage periods. The experiments were laid out in a split-plot design, with three replications. The main plots were devoted to harvest time i.e. harvest after 7, 14, and 21-day after irrigation cut-off (DAIC). However, the sub-plots were assigned to rice cultivars (Sakha106, Sakha107 and Sakha 108). The grain quality characteristics were studied at 6, 9 and 12-month after harvesting. Delaying the harvest date to 21-DAIC lead to a significant decrease in number of filled and unfilled grains/panicle, panicle weight and grain yield compared with 7- and 14-DAIC. The inverse was true in 1000-grain weight. Sakha 108 was superior to Sakha 106 and Sakha 107 in grain yield and its attributes. The highest grain yield was obtained from Sakha 108 at harvest time of 14-DAIC. Moisture content, hulling, milling and head rice percentages were gradually decreased by increasing storage period from 6 to 9 and 12-month. The inverse was found in amylose, elongation percentages and gelatinization temperature (GT). The intermediate harvest time 14-DIAC registered the highest values of all grain quality characteristics. Sakha 108 registered the lowest moisture content and the highest values of other grain quality. Generally, Sakha 108 harvested at 14-DAIC achieved the highest grain yield and quality at the 9-month storage period.
