Rice Cultivar Response to Seeding Date
Linscombe, S.D. and Levy, R.J.
New rice, Oryza sativa L., cultivars are continuously developed and released. To determine optimum seeding dates, new and existing cultivars (12-15) are planted each year over a broad range of seeding dates. Seeding normally begins in mid-late February and continues approximately every 15 days until late June. These studies have been conducted over the previous thirty plus years at the H. Rouse Caffey Rice Research Station near Crowley, Louisiana, USA.
The research has shown that in the Southwest Louisiana rice production region, optimum planting dates for most lines are late February through early April. However, some lines yield very well at earlier planting dates, but yields fall off significantly as planting is delayed to later dates. In contrast, for some lines, while yield is reduced at later dates, the falloff is not as significant. Ratoon cropping is important in Southwest Louisiana as in most years approximately 50% of the crop is ratooned. All planting dates that are harvested by the end of April are also ratoon cropped in these studies. This research has shown that some lines will produce excellent ratoon yields at earlier harvest dates, but ratoon yields are significantly reduced at later harvest dates. Conversely, some lines have much more consistent ratoon yield performance ranging across harvest dates. In addition to yield, milling performance is also evaluated in these studies.
This research is critical to assist rice producers in Southwest Louisiana in deciding on which cultivars to use depending on planting date and whether they will attempt to produce a ratoon crop. These studies also provide information on the impact of planting date on cultivar milling performance.
