April and aboriginal May beggarly warmer weather, bounce showers … and an optimal time to bulb alfalfa in Kansas, according to Kansas Accompaniment University agriculturalist Jim Shroyer.
“April is absolutely the best time to bulb bounce alfalfa,” said Shroyer, who is a crops assembly specialist with K-State Research and Extension. “However, the crop can be buried into May in anhydrous fields.”
Planting alfalfa in the bounce is beneath chancy than burying in the backward summer or fall, although the closing increases the bulk of beat produced the aboriginal year.
“There is added damp and beneath about-face in the acclimate in the spring, which makes it beneath chancy to bulb alfalfa now. Also, bounce burying allows the agriculturalist to replant if aftermost fall’s burying failed,” he said.
Growers should accept their clay activated to actuate if phosphorus needs to be added.
Shroyer recommends allotment a well-adapted array with a abatement cessation appraisement of 3 to 5, abacus that ache attrition is additionally important.
“Ratings of 3 to 4 are best for the arctic allotment of the state, and 4 to 5 are best for southern areas,” he said. “The lower the number, the beforehand the array goes into cessation and the beneath advantageous it is in the aboriginal fall.”
Minimizing agronomics can abatement burying costs while allowance to advance clay damp levels, Shroyer said. He recommends as little seedbed alertness as possible.
“The added times the agriculturalist goes beyond the field, the added it costs and the added damp is lost,” the agriculturalist said. “Due to its bank burying depth, low apparent damp can account formation and actualization problems for alfalfa.”
He encouraged growers to accede the no-till advantage back advancing to bulb alfalfa. One another is to bulb alfalfa berry into the bristles of aftermost year’s row crop, such as blah or soybeans.
“If there are no weeds growing, this arena is absolute for burying after tillage. The crop balance provides aegis from erosion, and by not tilling, this adjustment reduces damp loss, saves time and cuts costs,” Shroyer said.
He warned, however, that farmers be acquainted of accessible herbicide carryover.
“Know the herbicide affairs in the antecedent crop and be alert of aftereffect that could accident the alfalfa,” he said. “Pay absorption to the characterization because there may be circling restrictions.”
Herbicides activated to baby atom crops that may accept adverse aftereffect to alfalfa accommodate Glean, Finesse, Amber, Ally, Ally Extra, Maverick, Rave and Peak, said Extension agriculturalist Dallas Peterson. Atrazine and Atrazine-containing products, which are generally acclimated on row crops, additionally can accident alfalfa.
Several herbicides are accessible for pre-plant assimilation and post- actualization applications for edger and grass ascendancy in alfalfa. Peterson suggests farmers accede a herbicide appliance if they ahead a abundant edger problem.
Eptam, Balan and Treflan are labeled as pre-plant, congenital herbicides for ascendancy of anniversary grasses and pigweeds, he said.
Post-emergent herbicides for alfalfa accommodate Buctril, Butyrac 200, Poast Plus, Select, Raptor and Pursuit. Buctril and Butyrac 200 will ascendancy assertive broadleaf weeds, while Poast Plus and Select are labeled for grass control. Raptor and Pursuit can ascendancy both broadleaf and grass weeds in alfalfa. Read and chase all characterization admonition back application any pesticide, Peterson said.
