A total of 360 pigs (200 × 400 DNA) were used in a 43-d nursery trial (initially 12.4 ± 0.37 lb) to evaluate multiple strategies for allotting pigs to pens in swine research trials. At placement, the population was split into 3 cohorts with similar average weight and standard deviation. Each cohort was randomly assigned to 1 of 3 allotment strategies. Strategy 1 (random) utilized a simple randomization strategy with each pig randomized to pen independent of all other pigs. Strategy 2 [body weight (BW) distribution] sorted each pig within the cohort into 1 of 5 BW groups. One pig …

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 …

Could The Use Of Nitrification Inhibitor Optimize The Nitrogen Use Efficiency Of Corn Production?, Pedro Morinigo, Dorivar A. Ruiz Diaz

Kansas Agricultural Experiment Station Research Reports

Nitrogen (N) is an essential nutrient for corn production, higher grain yields are depen­dent on N fertilizer application. Substances like the nitrification inhibitors (NI) were created to increase yields, promote nitrogen use efficiency (NUE), and reduce N losses. The study was carried out in ten site-years in Kansas from 2017 to 2021, with the objec­tive of evaluating the nitrogen agronomic efficiency (NAE) in corn with and without the use of NI and comparing corn grain yield, grain N uptake, and soil mineral nitrogen content with the use of the NI. Nitrogen fertilizer at the rates of 100, 150, and 200 …

Phosphorus (P) fertilizer additions are often required to meet crop nutrient demands, but over-fertilization can have economic consequences, as well as environmental consequences from agricultural P loss. Therefore, we require management strategies that balance crop P demand and the need to minimize environmental P loss. The objective of this study was to investigate the effect of cover crop addition and P fertilizer management strategy [build and maintain (BM), sufficiency (SF), and a zero-P control (CN)] on crop yield of a no-till, corn-soybean system for 2020, 2021, and 2022 crop years for a site near Manhattan, KS. The addition of a …
