Abstract

In this paper was examined the milling yield and the percentage of head rice yield and grain breakage in San Andrea rice variety, depending on paddy moisture content at harvest and time of storage of paddy after harvest. The influence of moisture content in paddy in the time of harvest was analyzed through representative samples of paddy harvested in three different terms in production in 2013 (24.09.2013, 04.10.2013 and 14.10.2013). In paddy harvested in the first term was measured average moisture content of 22.8 %. Moisture content in paddy harvested in the second and third terms was 19.6 % and 16.3 % respectively. The highest milling yield (74.81 %) and head rice yield (64.64 %) was obtained from paddy with the highest average moisture content at harvest time. From the same variant was received the lowest percentage of grain breakage (10.17 %). To determine the influence of paddy time of storage, paddy was processed and kept one, two and three months after harvest. The milling yield and head rice yield from all three terms of harvest was the largest in the processing of paddy one month after harvest. From this variant was obtained the lowest percentage of grain breakage. The best results from variants of factor time of storage again were associated with variant with the highest percentage of moisture at harvest. Keywords: rice, milling yield, head rice yield, grain breakage
