The Federal Experiment Station in Puerto Rico is maintained at Mayaguez for crops investigations requiring a tropical environment. When established in 1902, the station was the only institution for agricultural research on the island. The research program included all of the diverse investigations such as animal husbandry, entomology, and forestry, in addition to crops studies, required for improvement of agriculture in Puerto Rico. Today, the Agricultural Experiment Station of the University of Puerto Rico is responsible for studies related entirely to insular agriculture. Research projects at the Federal station are selected for applicability, not only in Puerto Rico, but in other tropical areas as well. The Federal station also maintains projects with temperate-zone crops when these are needed to supplement investigations at locations on the mainland. Since 1961, the station has been part of the Crops Research Division of the Agricultural Research Service, and joint projects have been maintained with various other research units in the Division.
Simazine [2-chloro-4,6-bis(ethylamino-s-triazine)] sprays (2 or 4 g·liter-1) and supplemental N fertilizer (50 or 100 kg·ha-1) were applied to 3 Brassica species. Both N and simazine treatments increased total N content of leaves, but much of the increased N was not in the protein fraction. Amino acids were not inceased by the N fertilizer in most cases and were reduced by the simazine treatments. The treatments were not useful as a method for improving nutritional quality.
