The effect of mechanical weeding and fertilisation on perennial weeds, fungal diseases and soil structure were evaluated in two different experiments in spring cereals. Experiment I included six strategies. The first strategy was (1) without

Impact of crop production system on the content of macronutrients in potato tubers Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-03-04 Bogumił Rychcik; Jadwiga Wierzbowska; Milena Kaźmierczak-Pietkiewicz; Arkadiusz Światły
The content of macronutrients in potato tubers arouses interest because of their substantial consumption in the world and significant role in elements' budget in human diet. The research objective has been to evaluate the content of macronutrients in tubers of potatoes grown in different systems of crop production in Poland. In 2012–2014, an experiment was conducted to test potato cultivation in three-crop

Soil and crop responses to controlled traffic farming in reduced tillage and no-till: some experiences from field experiments and on-farm studies in Sweden Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-02-28 Ararso Etana; Lena Holm; Tomas Rydberg; Thomas Keller
ABSTRACT The purpose of this study was to investigate the impact of controlled traffic farming (CTF) with respect to soil physical properties and crop yield for Swedish conditions. Three field trials were conducted for six growing seasons in central and southern Sweden. In two of the trials, we compared CTF with random traffic farming (RTF) in deep chiseling (DC, 15–20 cm), shallow cultivation (SC

Response of hydroponic lettuce to aeration, nitrate and potassium in the nutrient solution Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-02-20 Daniela Alvarado-Camarillo; Luis Alonso Valdez-Aguilar; José Antonio González-Fuentes; Emilio Rascón-Alvarado; Fidel Maximiano Peña-Ramos
Purpose: Floating hydroponic system for lettuce greenhouse production consists of plants inserted in styrofoam platform floating in a 15 cm-tall nutrient solution, which is aerated by some growers while others maintain the solution static. The present investigation had the objective of determining the effect of NO3−-N and K in Romaine lettuce cultivated in floating hydroponic system and the impact

Response of oat-triticale mixture to post-emergence weed harrowing Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-02-18 Piotr Sobkowicz; Ewa Tendziagolska; Agnieszka Łagocka
In experiments with weed harrowing crops are negatively affected by competing weeds but also by the destructive effect of used implement. This research was carried out to find growth stages during which mixture of oat (Avena sativa L.) and triticale (× Triticosecale Wittm.) was resistant to harrowing and was able to effectively recover from this physical disturbance. Plots were harrowed 1–3 times on

Non-destructive estimation of winter wheat leaf moisture content using near-ground hyperspectral imaging technology Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-02-18 Zhen Zhu; Tiansheng Li; Jing Cui; Xiaoyan Shi; Jianhua Chen; Haijiang Wang
Accurate monitoring of crop moisture content is very important for irrigation scheduling and yield increase. This study aims to construct an optimal estimation model of winter wheat leaf moisture content (LMC) through spectral data processing and feature band selection. LMC and spectral reflectance were measured in 2017-2018 to construct models using simple linear regression (SLR), principal components

Screening for pre- and post-anthesis drought responses in selected bread wheat (Triticum aestivum L.) genotypes Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-02-12 Sibusiswangaye Yolanda Mdluli; Hussein Shimelis; Jacob Mashilo
Wheat genotypes with pre- and post-anthesis drought tolerance offer enhanced yield gains under water-limited environments. This study determined pre- and post-anthesis drought responses of selected bread wheat genotypes in order to identify and select candidate genotypes for breeding. Fifteen genetically differentiated wheat genotypes were evaluated under non-stressed (NS), pre-anthesis drought stress

Maize grain production, plant nutrient concentration and soil chemical properties in response to different residue levels from two previous crops Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-02-11 Juan Hirzel; Pablo Undurraga; Lorenzo León; Marcelo Panichini; Jorge Carrasco; Jorge González; Iván Matus
The incorporation of previous crop residues in agricultural management benefits soil fertility, crop production, and environment. However, there is no enough information about maximum residue application level without negative effect over next crop yield. To evaluate maize (Zea mays L.) yield under short-time conservation management with incorporation and/or importation of different residue levels

Diversity analysis of provitamin A maize inbred lines using single nucleotide polymorphism markers Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2020-01-29 Aleck Kondwakwenda; Julia Sibiya; Assefa B. Amelework; Rebecca Zengeni
The success of a breeding programme can be determined by the level of genetic diversity that exists among breeding materials. This study was carried out to (i) determine the level of genetic diversity that exist among the collection of tropical provitamin A maize inbred lines and (ii) evaluate the genetic structure and divergence of provitamin A maize inbred lines. Forty-six advanced provitamin A inbred

Changes in soil organic carbon fractions and bacterial community composition under different tillage and organic fertiliser application in a maize−wheat rotation system Acta Agric. Scand. Sect. B Soil Plant Sci. (IF 1.092) Pub Date : 2019-12-13 Daijing Zhang; Xueqian Yang; Yanjie Wang; Jiejing Zong; Jianhui Ma; Chunxi Li
The objective of this study was to assess the impact of different tillage and organic fertiliser regimes on soil carbon fractions and bacterial community composition within a maize–wheat cropping system. We conducted a six-year experiment on the Huang-Huai-Hai Plain of China. Six treatments were established: deep tillage (DT), shallow tillage (ST), no-tillage (NT), deep tillage with organic fertiliser
