On-Farm Research: It’s been fun discussing on-farm research projects and putting together protocols with growers the past few weeks! Some have asked if there’s already projects for which we need cooperators. We do have those and we also custom develop protocols depending on the question(s) you wish to look at. For those curious about protocols developed, you can view some at: https://cropwatch.unl.edu/farmresearch/extensionprotocols.
One question I’ve received quite a bit the past few years is about establishing cover crops into V5-6 corn. We don’t have on-farm research data yet for this study topic, but perhaps this year a few of you will consider it! The thought is to get the cover established, even though it won’t grow much during growing season, and hopefully provide for faster growth after harvest. I have developed an on-farm research protocol if growers are interested in trying this (it can be found at the same website listed above). In our brainstorming session, growers talked about interseeding via retrofitting equipment to put seed on similar to Y-drops, using a coulter, or seeding during cultivation. There is also a field day on March 21 to discuss what one farmer has tried the past three years regarding different seeding mixes and ways of establishing the cover at V6. If you’re interested in attending, it will be held at 4th Ave and 1/4 mile north on Arthur Road near St. Libory, NE from 1:30-3:30 p.m. The following website has more information regarding this field day: http://cpnrd.org/wp-content/uploads/2018/03/Cover-Crop-Field-Day-Flyer-March21.pdf. If you’re interested in attending, please RSVP Dean Krull: email@example.com. Please let me know if you’re interested in the V6 cover crop protocol as well! Also just a note, this protocol can also be adapted for any of you looking at applying nutrients during that V5-V6 time-frame. The plot pattern would be the same; the objective and perhaps some of the data collection would change.
Soil Moisture Status in Non-Irrigated Fields: This week I plan to install soil moisture sensors into some non-irrigated fields in the southern area of counties I serve. I’m just curious where we’re truly at for soil moisture deeper in the soil profile knowing Kansas is in drought and moisture this winter has been spotty. I did this in 2013 as well to see where we were at after the drought of 2012; it showed we didn’t have a full soil profile going into the growing season. If you have moisture sensors, you may wish to consider doing this as well for your fields or pastures to know where you’re at. It may influence cropping decisions for 2018. If you connect sensors to dataloggers, you will want to also install a temperature sensor to allow the datalogger to base the moisture readings on the current soil temperature.
Check out this week’s UNL CropWatch at http://cropwatch.unl.edu for information on averaged land values dropped by 3% from 2017, negotiating fair leases, assessing alfalfa winterkill, interseeding into thin alfalfa stands, and more.
Innovative Youth Corn Challenge: Nebraska Extension and the Nebraska Corn Board are offering the seventh Innovative Youth Corn Challenge contest. This contest, open to 4-H members (age 10 & older as of Jan. 1st) or FFA members (in-school members), guides participants through all aspects of corn production, as well as agricultural careers related to corn production. As a team (2 or more participants), youth will be challenged to implement a production practice different than normal to determine if they increased their yield. Economics and sustainability of the practice will also be considered. Yields, cropping history, and production information will be collected in the Corn Yield Challenge management summary. Cash prizes and plaques are given. First place receives $1,000, second place receives $500, and third place receives $250. Sustainability, crop scouting and “extra mile” awards are also given as cash awards. To participate in 2018, youth must complete and return an entry form by APRIL 1st to the Fillmore County Extension Office in Geneva, NE. Forms can be downloaded at https://cropwatch.unl.edu/youth/cornchallenge. For more information, contact Brandy VanDeWalle at firstname.lastname@example.org.
Horticulture Information from Kelly Feehan, Platte County: “Interested in getting an early start on vegetable gardening? You don’t need a greenhouse; just check out row covers that can be placed over plants to provide some protection from cold temperatures. Row covers are spun-bonded or woven polyester or polypropylene material that can be placed over plants to extend the growing season by retaining heat. Row covers are permeable and allow in light, water and air for plant growth. Depending on the weight of material used, between 2 and 8 degrees of frost protection can be gained, allowing earlier planting in spring or later planting in fall to move the harvest season up by a week or two or extend it a week or two later in the fall. Row covers can be draped over plants and secured with bricks; or they can supported by hoops, in which case they’re called low tunnels. Low tunnels are an easy and good season extender for home gardeners to use.
Rhubarb is a perennial that can live for years; however, plants should be dug and divided every 5 to 10 years. This is best done from late March into early April. Dig rhubarb plants, then use a sharp knife or axe to cut crowns into sections, each containing two pinkish buds. Incorporate organic matter into soil; then replant divisions 2 to 3 feet apart. Plant shallow so buds are only one-half to one inch below soil. Do not harvest newly divided or planted rhubarb the first year to allow plants to establish roots and recover from division or transplanting. During the second season, harvest only a few stalks to allow plants to continue to build up energy reserves. For three year or older plants, the harvest season can last up to 8 weeks. Harvest the largest rhubarb stalks by pulling them slightly to the side so they break away from the plant. Avoid harvesting more than one-third of rhubarb stalks at one time so plants are not weakened.”
