ABSTRACT Agriculture needs to supply food for a growing population whilst also minimising the environmental impact, and the adoption of sustainable agriculture systems has been proposed as a solution to achieve this. The objective of this study was to evaluate the effects of seven fertilisation treatments (FT1-FT6 organic fertilisers, FT7 conventional fertiliser) and two irrigation methods (drenching

Agricultural land management may influence crop nutritional quality. However, few studies have explored potential connections between crop quality with different land management strategies. We analyzed mineral and crude protein concentrations in spring wheat grain (Triticum aestivum L.) samples from a study in Mandan, North Dakota conducted from 2006–2014. The study introduced a perennial forage phase

Orchardgrass (Dactylis glomerata L.) could serve as a cool‐season perennial in southeastern production systems, but often does not behave as a true perennial under high temperature stress conditions of the region. This work sought to develop heat tolerant orchardgrass germplasm through recurrent phenotypic selection (RPS) that would both reduce secondary seed dormancy caused by high soil temperatures

Tomato fruit represent a valuable but perishable commodity due to postharvest fungal spoilage. In the present investigation, greenhouse-grown tomatoes were analysed, particularly for the contamination by mycotoxigenic fungi. Collected isolates were characterized by morphological features and sequencing of barcoding genes. Alternaria, Aspergillus, and Penicillium proved to be the most represented genera

Abstract Soil aggregates and associated carbon (C) and nitrogen (N) stocks are important for soil organic matter (SOM) consequences and quality. The study is meaningful to understand the mechanisms of how fertilization management affect C and N stocks. Tobacco monocropping systems with four fertilizer treatments (0, 75, and 112 kg N ha−1, and 60 kg N ha−1 + Manure) were established in 1998. After 19

Nitrogen (N) fertilizer is commonly applied to wheat crops (Triticum aestivum L.) during the vegetative growth to meet crop requirements. Current decision rules for N application result in N losses to the environment, and thus to low N use efficiency, due to excess of N fertilizer and/or poor synchrony between soil supply and crop N demand. Despite existing tools and methods to manage N fertilization

Drought stress affects yield formation of sugar beet. Under climatic changes with longer periods of drought, the development of sugar beet varieties with a higher drought stress tolerance is gaining importance.

The common potato, Solanum tuberosum L. (2n = 4x = 48), has 100–200 related wild taxonomic species endemic to the Americas, which constitute invaluable sources of genetic diversity. They form a polyploid series with 2n = 2x‐6x (x = 12), and can reproduce asexually by tubers and stolons and/or sexually by seeds. Information is scarce on their preponderant mode of reproduction, and its consequences on

Accurate estimation of the spatial pattern of annual soil erosion and sediment yield is of paramount importance in watershed conservation measures, design of sedimentation dams, reduction of reservoir storage capacity, integrated watershed management, flood problems, and alteration of ecosystems’ locations. One of the most widely used empirical/ conceptual methods for estimating soil erosion and the

ABSTRACT Dicyandiamide (DCD) has been extensively used to retard nitrification process and decrease nitrogen (N) losses. However, its efficacy is variable and inconsistent depending upon the environmental conditions. The effects of temperature and moisture on DCD degradation and carbon dioxide (CO2) release from calcareous soil are not well-known. Therefore, an incubation experiment comprising three

To this end, this research was carried out with the aim of evaluating whether Si

ABSTRACT The accumulation of radiocaesium in the grains of 15 rice cultivars was monitored in 2014 and 2015. The study area was a local paddy field with low soil potassium concentrations, where highly radiocaesium contaminated rice had been commercially harvested because of the Fukushima Daiichi Nuclear Power Plant accident. The concentrations of radiocaesium in the resulting brown rice were all high

Among abiotic stressors, cold is one of the most harmful for the cultivated potato, a frost‐sensitive crop. RNAseq profiling of two different clones of S. commersonii contrasting in their capacity to withstand low temperatures revealed a higher number of differentially expressed genes (DEGs) under non‐acclimated (NAC) conditions in tolerant clone cmm1T compared to the susceptible cmm6‐6 (1,002 and

Previous results from our lab have shown that optical sorter‐based indirect selection reduced deoxynivalenol (DON) accumulation in soft red winter wheat (SRWW). In this paper we evaluate the efficacy of optical sorter‐augmented genomic selection (OSA‐GS) for lower DON accumulation at three selection intensities across two years. In total, 758 SRWW breeding lines were genotyped and then phenotyped in

Hard fescue (Festuca brevipila Tracey, 2n = 6x = 42) is a cool season turfgrass with a fine leaf texture that performs well under low‐input management. Breeding and genetics studies of F. brevipila have been limited due to the complexity of its hexaploid genome. To advance our knowledge of F. brevipila genomics, we used PacBio isoform sequencing to develop a reference transcriptome for this species

Drought stress is one of the most important factors limiting soybean (Glycine max [L.] Merr.) productivity and reducing yield stability. Soybean breeders need phenotypic and genotypic tools to improve the drought stress tolerance but most of available strategies are expensive and unaffordable for small‐scale public breeding programs. In this context, elite germplasm of a locally adapted breeding population

A critical step towards the success of the doubled haploid (DH) technique is the haploid identification within induction crosses. The R1‐nj marker is the principal mechanism employed in this task enabling the selection of haploids at the seed stage. Even though it seems easy to identify haploid seeds, this task is performed manually by visual classification, which becomes an inefficient process in

Four ecotypes

From ancient times, the economic growth of India is mainly based on agricultural output. Agriculture is demographically the broadest economical sector and acts as an important part in the entire socio-economic fabric of India. Nearly half of the population of our country are connected to agriculture as their industry and make a livelihood out of it. At the same time, the crop productivity depends upon

Abstract Synthetic chelating agents have high cost and low biodegradation in the environment; thus, the use of natural complexing agents for iron increases the sustainability in crop production. The aim of this study was to verify the efficiency of natural organic acids added to the nutrient solution on the Fe acquisition. For that purpose, two experiments were carried out using soybean and maize.

Developing more sustainable forage systems requires efficient decision support tools for fertilization management. Soil phosphorus (P) tests have long been used as decision support tools for fertilization management but, more recently, plant nutrition indices using the P concentration of shoot biomass were developed to assess the P nutrition status of grasslands. The objectives of this study were to

Phosphorus fertilization and liming are alternatives used to increase forage production in Southern Brazil grasslands (Pampa grasslands) and to avoid its replacement by cultivated exotic crops. However, changes in natural soil fertility can significantly affect the equilibrium of natural vegetation communities. We hypothesized that triple and simple superphosphate and limestone using would lead to

Mepiquat chloride (MC) is essential to reduce shoot growth and improve cotton harvest index, but the effect of high rates on cotton root growth is not known yet. The objective of this study was to evaluate the effect of different rates of MC application on root and shoot growth of different cotton cultivars. Two studies were conducted in a greenhouse with the following objectives: i) characterize the

Trinexapac‐ethyl (TE) is a plant growth regulator commonly used in cereal production systems. It retards plant growth by inhibiting gibberellin (GA) biosynthesis, thereby reducing the risk of stem lodging. Lodging at the latter stages of crop development can compromise grain yield and quality. Thus, application of TE may protect yield and quality in winter cereals. A field study was conducted from
