Knowledge of complex relationships between soils, crops, and management practices is necessary to develop sustainable agricultural production systems. Objectives were to determine how maize (Zea mays L.) would respond to monoculture (C-C), 2-yr rotation (C-S) with soybean [Glycine max (L.) Merr.], or 4-yr rotation (C-S-W/A-A) with soybean, wheat (Triticum aestivum L.), and alfalfa (Medicago sativa L.) under different N input levels. We evaluated N fertilizer input (8.5 or 5.3 Mg/ha yield goal…

Soil Attributes, Soybean Mineral Nutrition, and Yield in Diverse Crop Rotations under No‐Till Conditions

Development of sustainable crop rotations depends on understanding complex relationships among soils, crops, and yield. Our objectives were to measure how soil chemical and physical attributes as

Row and forage crop rotation effects on maize mineral nutrition and yield

Abstract: Diverse crop rotations are an integral component of sustainable agriculture. The objectives were to investigate row and forage crop rotation effects on stover biomass, grain yield, and

Rotation and Fertilization Effects on Soil Quality and Yields in a Long Term Field Experiment

Understanding the complex relationships among soil quality, crop productivity, and management practices would help to develop more sustainable agricultural production systems. In this study, we

Agronomic Performance of Cropping Systems with Contrasting Crop Rotations and External Inputs

Cropping systems with less reliance on external inputs could improve agricultural sustainability if they can produce high and stable crop yields over time. A 16-yr experiment was conducted in

Agronomic productivity of conventional and low-external-input cropping systems and their effect on giant foxtail (Setaria faberi) population dynamics

Low-external-input (LEI) cropping systems that include forage legumes and small grains in addition to corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] can achieve similar or higher crop

Comparison of crop management strategies involving crop genotype and weed management practices in conventional and more diverse cropping systems

The results indicate that more diverse crop rotation systems can be as profitable as conventional corn–soybean systems and can provide farmers with greater flexibility in crop management options.

Hybrid Selection and Agronomic Management to Lessen the Continuous Corn Yield Penalty

Yield reductions occur when corn (Zea mays L.) is continuously grown compared to when it is rotated with soybean [Glycine max (L.) Merr.]; primarily due to soil nitrogen availability, corn residue

Nitrogen fertilizer applications to maize after alfalfa: grain yield, kernel composition, and plant mineral nutrients

Nitrogen (N) is often applied to first year maize (Zea mays L.) after alfalfa (Medicago sativa L.) at rates greater than needed to attain maximum yields. This study explored other potential benefits

Soil residual nitrogen under various crop rotations and cultural practices

Crop rotation and cultural practice may influence soil residual N available for environmental loss due to crop N uptake and N immobilization. We evaluated the effects of stacked vs. alternate-year

Highly Arid Oasis Yield, Soil Mineral N Accumulation and N Balance in a Wheat-Cotton Rotation with Drip Irrigation and Mulching Film Management

Nitrogen inputs need careful reconsideration, especially the initial soil Nmin, fertilizer N inputs, dry and wet deposition, and appropriate organic and straw inputs which are all factors that must be taken into account under very arid conditions.



Corn and Soil Fertility Responses to Crop Rotation with Low, Medium, or High Inputs

It is suggested that the level of inputs provided for corn can affect the crop rotation response, and grain yield responded differently to input levels within the two rotations.

Soil Nitrogen Mineralization Influenced by Crop Rotation and Nitrogen Fertilization

An estimate of soil mineralizable N is needed to determine crop needs for N fertilizer. The objective of this research was to estimate soil net N mineralization in soils maintained in continuous corn

Corn Yield, Nitrogen Use, and Corn Rootworm Infestation of Rotations in the Northern Corn Belt

Crop rotation may improve production efficiency and reduce fertilizer N requirements for corn (Zea mays L.). Objectives were to determine effect of rotation and N on corn yield, efficiency of water

Crop Rotation and Soil Amendment Alters Sorghum Grain Quality

Soybean [Glycine max (L.) Merr.] rotation enhances grain sorghum [Sorghum bicolor (L.) Moench] yield, but influence on grain quality has not been measured. The objective was to determine the effect

Uptake of Nitrogen from Soil, Fertilizer, and Crop Residues by No-till Corn and Soybean

The relative availability of nitrogen (N) from indigenous soil organic N, immobilized fertilizer N, currently applied fertilizer N, and crop residues is largely unknown. A nonirrigated experiment was

Crop Sequence Affects Nutrient Composition of Corn and Soybean Grown under High Fertility

It was hypothesized that the rotation effect observed in longterm sequences of corn and soybean might be due to an increased nutrient concentration, not just an increased accumulation, and a positive effect of rotation on yield was observed in both crops.

Monoculture and rotation system effects on precipitation use efficiency of corn

Development and utilization of cropping systems in rainfed areas are highly dependent on their water use efklciencies, especially in subhumid areas. The objective was to evaluate the effect of crop

Crop Yield as Affected by Rotation and Nitrogen Rate. III. Corn

Corn (Zea mays L.) is a widely grown crop in the USA that re-sponds positively to crop rotation. This study compares yields of corn grown in continuous monoculture with that of a (i) 2-yr soybean

Crop rotation is reported to increase grain sorghum [ (L.) Moench] yield in some, but not all cases. This study compares yield of continuous grain sorghum with that of sorghum grown (i) in a 2-yr
