Evaluating the Adapt‐N model for dynamic nitrogen recommendation in Brazilian maize (Zea mays L.) systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Several nitrogen rate recommendation methods have been developed to help farmers fertilize close to the economic optimum N rate (EONR). The objectives of this study were to (i) evaluate a dynamic method (Adapt‐N) for N rate recommendations for maize (Zea mays L.) in Brazil relative to EONRs determined specifically for each trial and (ii ...

Preliminary Functional Group Patterns of Arthropods in a Maize Field and Adjacent Cultivated Refuge Strip in South Africa

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Agricultural intensification is a major driver of global arthropod declines. Habitat management strategies, such as cultivated refuge strips (CRS), can counteract these effects by enhancing biodiversity, promoting conservation biological control and improving agroecosystem resilience.

EFEKTIFITAS KOMPOS TANAMAN Crotalaria juncea PADA KETERSEDIAAN DAN SERAPAN N, P, K SERTA PERTUMBUHAN TANAMAN JAGUNG MANIS (Zea mays saccharata Sturt) PADA ENTISOL WAJAK, MALANG

JTSL (Jurnal Tanah dan Sumberdaya Lahan), 2018
The problem of Entisol used for agricultural land is the loss of nutrients due to leaching and evaporation. It is thus necessary to keep the nutrients available in the soil.

Structural Quality of an Ultisol Under Long‐Term Different Tillage Systems and Cover Crops With Corn in Northeast Brazil

Soil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Dual‐purpose corn cropping is a widespread and economically important agricultural activity in Brazilian rural areas. The objective of this work was to study the structural quality of a dystrophic Red‐Yellow Ultisol under different tillage systems, previous crops and inoculant treatments, and its relationship with corn yield.

Time of harvest and storability of Crotalaria juncea L. seeds

REVISTA CIÊNCIA AGRONÔMICA, 2018
ABSTRACT Although used as green manure, one of the challenges the cultivation of Crotalaria juncea is the low availability of quality seeds in the market. The harvest at the right time contributes to the achievement of better quality seeds. The objectives of this study were to evaluate the storability and characterize the physical and physiological ...

Initial insights into sunn hemp–corn intercropping for forage production and nitrogen reduction

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Corn (Zea mays) is a globally important crop to produce grain and silage for livestock systems. However, corn generally requires high levels of nitrogen (N) fertilizer. Introducing sunn hemp (Crotalaria juncea L.; SH), an annual legume, is a potential option for reducing N inputs.
