Effect of harvesting time on the quality of milled rice of three paddy varieties (BR 11, BR 22 and BRRI dhan31) were studied in the BRRI farm. The results showed that milling yield was highest at optimum maturity level, while decreasing after optimum maturity irrespective of the varieties under test. Total milling yield recovery was higher in BR 11 (73.0 %) than those of other two varieties.

To find out the optimum time of harvesting for obtaining the good quality of milled rice

Three paddy varieties (BR 11, BR 22 and BRRI dhan 31) were grown in the BRRI field. The date of sowing and transplanting were same for all these three varieties. Paddy was harvested at weekly interval for 28 days. The first harvest was done one week before maturity. After harvesting, paddy was threshed by pedal thresher. Then threshed paddy was cleaned and sun dried at 11.6 - 13.8% moisture content. The paddy samples were milled by laboratory Satake husking and milling machines for analyzing milling yield (MY), head rice (HR) and broken rice (BR) recovery.
