Abstract

Paddy harvest time (PHT) and its moisture content at milling process (MCMP) are two major factors determining the milling quality of rice. In this regards, a field research was conducted to study the effect of these factors on milled rice breakage (MRB) and ratio of cracked kernels (RCK) of Hashemi paddy cultivar in north of Iran. Five harvest times of 24, 27, 30, 33, 36 days after fifty percent flowering (DAFPF) and four milling moisture contents of 8-9, 10-11, 12-13, and 14-15% dry basis (d.b.) were considered for the research. Results showed that the effects of PHT and MCMP were significant on the MRB and RCK (P < 0.01). The lowest (16.32%) MRB was recorded at 30 DAFPF; however there was no significant difference between values at 27 and 30 DAFPF (17.02 and 16.32%, respectively). Results also indicated that the lowest (9.84%) MRB mean was obtained at 8-9% d.b. of MCMP. The least (1.813%) RCK was obtained at 27 DAFPF; however there was no significant difference between the RCK at 27 and 30 DAFPF (1.813 and 1.750%, respectively). Besides, the lowest mean values of RCK (1.048 and 1.288%) were determined at 8-9 and 10-11% MCMP. As a final conclusion, in order to gain the least MRB and RCK, the most suitable situations for harvesting and milling the ‘Hashemi’ cultivar in north of Iran were determined to be harvesting at 30 DAFPF and milling at PMC of 8-9% d.b.
