Grain quality of irrigated lowland rice varieties as affected by season and crop establishment
2015
Bandonill, E.H. | Corpuz, G.G.
Four irrigated lowland rice cultivars were grown during dry and wet season to determine the effect of crop establishment (transplanting and direct-seeding) on the grain quality parameters milling potential, chalkiness, and amylase content. NSIC Rc138 had significantly higher milling recovery, chalky grains, and amylose content followed by PSB Rc18 and PSB Rc82. NSIC Rc122 had significantly the least amount of milled rice recovered. Grains harvested during dry season had lower chalky grains but higher head rice recovery than wet season. Grains harvested from transplanted (TPR) rice had higher brown and head rice recovery than direct-seeded (DSR)rice but not differ in terms of milling recovery. The TPR samples had significantly lesser chalky grains and lower apparent amylose content. The results initially showed that transplanting produces better quality rice than direct-seeding. Follow up studies should be conducted to confirm and further explain in the findings.
