6 considerations for preflood nitrogen for rice

Preflood application of urea+NBPT to rice.

• By Trent Roberts, Rick Norman and Jarrod Hardke • Preflood nitrogen (N) applications in rice are very important for setting yield potential in rice as two of the three yield components (tiller number and seeds per panicle) are set by the preflood N. The efficiency of preflood N uptake in rice is influenced by many factors including N source, ... Read More »

Consider these management tips for late-planted rice

fertilizer spreading

• By Jarrod Hardke • Rice drills continue to roll up and down eastern Arkansas. I think most are very aware we’ve been on the slowest planting pace in 25 years to get us here focusing on late May to early June planted rice.

This production practice is finding a substantial rotational fit for growers to save on land management costs, primarily associated with expenses related to tillage. Ultimately, there are some important management considerations that go with this unique and evolving production practice compared to our traditional delayed-flood rice management. ... Read More »

Delay nitrogen, delay yield

aerial fertilizer applicatioin

The hot, dry conditions of 2018 were the poster child for difficulty establishing a timely flood to incorporate nitrogen (N) fertilizer. To achieve consistently high yields, timely application and incorporation of preflood N is the most critical input in rice. Luck always helps, of course. The DD50 Rice Management Program (http://DD50.uaex.edu) is critical for timing preflood N. Originally developed to ... Read More »

Take these steps to prepare for possible fertilizer shortages
