Based on cool weather, UC recommends changes in N, pest strategies

seed rot

• By Bruce Linquist and Luis Espino • Earlier this week, I sent out a blog discussing N management during a wet year. In the blog, one scenario (Scenario 2) mentioned was, “I decided not to apply aqua but just go ahead and flood field when the rains started.” I was traveling around the valley yesterday looking at fields, and ...

3 ways to manage nitrogen fertilizer when it rains during planting

aqua N application rig

• By Bruce Linquist • Rain in May, especially in the amounts we have seen this year, are far from ideal for rice growers. It makes establishing seedling, nitrogen management and weed control extra challenging. Rain in May is not new. In 1995, 1996, 1998 and 2005, average May rainfall in the Sacramento Valley was 2.3 inches and average statewide ... 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

fertilizer spreading

• By Trent Roberts • With current Mississippi River levels above flood stage along all of Arkansas’ eastern border, there are increasing concerns that limited barge traffic combined with reduced access to Arkansas ports may tighten fertilizer stocks during periods of high use. Current river depth at Memphis is at 30 feet and falling: however, there is still a significant ... Read More »

Consider a seed treatment to boost seedling vigor

seedling disease

Early season disease management is becoming increasingly important as Texas rice farmers trend toward planting earlier at lower seeding rates (about 50 percent of Texas rice acreage is planted to hybrids). Clearly, the earlier plantings have a better chance of producing both high-yielding main and ratoon crops. But planting earlier means exposing seed to lower temperatures and possibly wetter soil, ...

Growers have new tools in their toolbox for 2019

texas pesticide collection

We have been fortunate to see new products on the market for rice over the past few years. These products have put more tools in the toolbox for us to use to manage our rice crop. In 2018, we saw three new herbicides (Loyant, Gambit and Provisia), one new herbicide premix (RiceOne), one fungicide (AmistarTop) and of course, the new ... Read More »

Researchers: Fertilizer choice can affect methane-producing organisms in soil

sampling rice fields for methane

University of Arkansas System Division of Agriculture rice research may lead to more sustainable crop production in the state and around the world. The quest for increased sustainability in agriculture and other industries includes examining greenhouse gases and how they’re generated. In the United States, only a small fraction of greenhouse gases are attributed to agriculture – 8.6 percent, according ... Read More »

Dustin Harrell answers common N management questions

fertilizer

Nitrogen is one of the largest expenses in a rice production budget. Efficient use of fertilizer N not only helps maximize grain yield, but it also helps lower fertilization rates, lower fertilizer expenses and minimize negative effects on the environment. There are a handful of questions that I get asked annually regarding N fertilization, and I thought I would take ... Read More »
