Effect of Early Harvest and Variety Difference on Grain Yield and Pasting Properties of Brown Rice

Green grains that are harvested before maturity and dehulled have been reported to higher nutritional value than fully matured brown rice. Two years of aerobic field experiments were conducted determine the effect variety, early harvest their interaction, on grain yield pasting properties Eight varieties grown under well-watered or water deficit conditions between 15–35 days after flowering (DAF). The maximum green rice was obtained when crops 20–25 DAF for condition 15–20 condition. paddy these dates average 66% mature yield. Varieties consistent in at with correlation coefficient being 0.897 ** two years. Rapid visco-analysis (RVA) showed developing had lower viscosities grains. However, variety difference a greater time. characteristics harvests, growing seasons. Water reduced but did not significantly affect flour gel, amylose protein content.
