The Lajas Valley is a semiarid region located in the southwestern corner of the Island. Annual rainfall fluctuates from 40 to 60 inches with rather prolonged dry spells. Guinea grass is the prevailing and most important pasture forage. Very little or no fertilizer at all is used and, generally speaking, the grazing management is poor. In 1952, an experiment was started with Guinea grass submitted to different fertilizer treatments, under rotational grazing. A randomized-block design already described in another paper (3) was used and each treatment of 0, 40, and 80 pounds of nitrogen per acre was applied as ammonium sulfate every 4 months was replicated three times. Results obtained indicate that fertilization pays even in this relatively dry section of the Island.

Comparisons are made concerning labor required and profitability associated with continuous grazing at three stocking rates and rotational grazing at a high stocking rate in the U.S. Gulf Coast region. A unique data set was collected using a time and motion study method to determine labor requirements. Profits are lowest for low stocking rate–continuous grazing and high stocking rate–rotational grazing. Total labor and labor in three specific categories are greater on per acre and/or per cow bases with rotational-grazing than with continuous-grazing strategies. These results help to explain relatively low adoption rates of rotational grazing in the region.
