In search of techniques to reduce irrigation water use in the Ogallala Aquifer region, several deficit irrigation techniques were evaluated in corn and cotton production. Several iterations of deficit irrigation (based on ET), including partial root-zone deficit (PRD) and regulated deficit irrigation (RDI) treatments, were implemented in the 2021 and 2022 summer season. Corn and cotton did respond to the different deficit irrigation treatments. Significant yield advantages were observed in fixed PRD on both crops while RDI also showed some yield advantage for corn.

Effect Of Defoliation At Different Stages On Grain Sorghum, K. L. Roozeboom, B. Owuoche
Kansas Agricultural Experiment Station Research Reports
Loss of leaf area usually results in yield loss in grain crops, but the amount of yield loss varies with extent and timing of defoliation. Grass crops, such as corn and grain sorghum, are particularly sensitive to leaf area loss near the time of seed set because there is little opportunity for the plant to compensate. An experiment to quantify yield reductions associated with various levels of defoliation imposed at different stages of grain sorghum development was conducted at Manhattan, KS, in 2022. Target defoliations of 0, 33, 66, and 100% were imposed at 5-leaf, flag-leaf-appearance, half-bloom, and hard-dough stages. …

Kansas Agricultural Experiment Station Research Reports
Weaning is a stressful event for calves. Various management practices have been suggested to reduce weaning stress. The purpose of this study was to evaluate three different weaning management practices on calf gains at weaning. Eighty-eight bull and heifer calves were assigned to one of three weaning treatments at two research locations. The weaning management options were abrupt weaning, fence-line weaning, and use of a nose-flap weaning device. Calves were weighed at the start of the measurement period and then two weeks later after weaning was completed. Calves that were weaned using the nose-flap method had significantly lower gains than …

Kansas Agricultural Experiment Station Research Reports
The objective of this research was to determine application variable influence on Plainview SC (aminocyclopyrachlor/imazapyr/indaziflam) efficacy in an industrial setting. Plainview SC was applied at three rates and three application timings using two nozzle types to compare season-long weed control in noncropland. Late-season kochia control was best when Plainview SC was applied at 48 or 64 oz/a using flat-fan nozzles. Application timing did not affect these treatments. Similar control using the boomless nozzle required 64 oz/a of Plainview SC be applied either in fall or winter.

Source-Sink Manipulation And Its Impacts On Canola Seed Filling Period, D. Ricciuto, M. A. Secchi, A. J. P. Carcedo, L. Nieto, J. Lacasa, M. Stamm, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Canola yield production is driven by the balance between source (leaves) and sink (pods and seeds) activity during the reproductive period of a crop. However, previous literature has not reported the impact of source-sink limitations under different nitrogen (N) supplies, and its effect on seed filling. Therefore, the objectives of this study were to 1) explore the impact of source-sink manipulations during the seed filling period and its main parameters: duration and rate; and 2) understand the interactions between N supply and source-sink manipulations to explain variations in seed weight. With these objectives, a field experiment was conducted during 2019–2020 …

Nitrogen And Phosphorus Rates’ Impact On Different Varieties Of Alfalfa In Central Kansas, Mariana O. Mota, Luiz O. Pradella, Wallas M. Da Silva, Romulo P. Lollato
Kansas Agricultural Experiment Station Research Reports
The United States is the largest producer of alfalfa (Medicago sativaL.) in the world, with a vast area grown under rainfed conditions. Under these conditions, and especially in a transition state such as Kansas, the alfalfa crop often suffers from water deficit stress. Environments under water-limited conditions promote a decrease in crop yield when inadequate water leads to an nitrogen deficiency and reduces crop biomass. This research aimed to investigate the production of different alfalfa varieties under different nitrogen and phosphorus rates in a rainfed environment. Three nitrogen application rates (0 lb/a; 200 lb/a; 400 lb/a) and three …
