The overall objective of the agronomy project at the Rice Research Station is to enhance rice production in Louisiana by evaluating and improving nutrient and cultural management practices. In the 2006 growing season, the agronomy project had over 62 field plot experiments in the ground at the Rice Research Station as well as at several off-station sites in producer fields throughout Louisiana.
One of the most important nutrient management studies undertaken every growing season by the agronomy project is the evaluation of nitrogen fertilizer requirements for soon-to-be-released rice varieties and experimental hybrids. Other essential fertilizer nutrients, such as phosphorus, potassium, sulfur and zinc, are also evaluated. The resulting data are then used to update and improve soil testing and fertilizer recommendations for Louisiana rice farmers.
Cultural management practices evaluated by the agronomy project include seeding rate, tillage systems, planting methods and crop rotation systems. In addition, several research studies are focused on cultural and nutrient management practices that have the potential to improve the productivity of the ratoon crop, i.e. the second rice crop, for the Gulf Coastal Plains rice-producing areas.
The agronomy project also participates in the LSU AgCenter’s statewide variety testing program for soybeans, grain sorghum and wheat. Results and recommendations from all studies are published in LSU AgCenter publications and scientific journals and are presented at several regional, state and national meetings annually.
