Abstract

The yield of seven medium-grain rice varieties was determined in bimonthly plantings at Gurabo. Chontalpa 16, Brazos, and Vista were the highest yielding varieties averaging 5,700 kg of rough rice/ha, but yields of Brazos varied more with season of the year. Yields were highest for February plantings and lowest for October plantings, followed by those for August. Similar yields for all seven varieties averaging about 5,100 kg/ha, were produced when the rice was planted in April, June or December. Varieties and season of the year affected the time required from planting to harvest, which averaged from 101 to 125 days. Lodging was most prevalent in the August plantings, averaging 34%. Nato and Saturn were the most prone to lodging, averaging 21 and 43%, respectively.
