Coexistence via resource partitioning fails to generate an increase in community function. [PDF]

PLoS ONE, 2012
Classic ecological theory suggests that resource partitioning facilitates the coexistence of species by reducing inter-specific competition. A byproduct of this process is an increase in overall community function, because a greater spectrum of resources

Biomass and protein in ruzigrass intercropped with maize subjected to plant densities and nitrogen fertilization

Pesquisa Agropecuária Brasileira, 2023
The objective of this work was to evaluate the impacts of nitrogen topdressing fertilization and plant density of second-crop maize on the biomass and crude protein production of ruzigrass (Urochloa ruziziensis) grown in intercropping. The experiment was

Impact of elevated CO2 on high temperature induced effects in grain yield of chickpea (Cicer arietinum)

The Indian Journal of Agricultural Sciences, 2016
High temperature and increasing atmospheric CO2 are debatable issues under climate variability and of major concern for agricultural productivity. Field experiments were conducted with two chickpea (Cicer arietinum L.) genotypes, viz.

Carbon budget of the vineyard \u2013 A new feature of sustainability [PDF]

, 2015
Vineyards received scarce attention in relation to the continuous monitoring of carbon fluxes and the assessment of their overall budget, as a common believe is that agricultural crops cannot be net carbon sinks.

Supplementary Light with Increased Blue Fraction Accelerates Emergence and Improves Development of the Inflorescence in Aechmea, Guzmania and Vriesea

Horticulturae, 2021
In protected cultivation, increasing the light level via supplementary lighting (SL) is critical to improve external quality, especially in periods with low light availability.

Simulating Organ Growth in Wheat Based on the Organ–Weight Fraction Concept

Plant Production Science, 2002
Quantifying dry matter partitioning into individual organs of plants is a key component for simulating crop growth and yield formation. This study was undertaken to develop a dynamic module of biomass partitioning over the entire duration of growth in ...

Nitrogen balance and gap of a high yield tropical soybean crop under irrigation

Frontiers in Plant Science, 2023
Nitrogen (N) is the most extracted and exported element by the soybean crop. In high yield tropical environments with irrigation, little is known about N accumulation in different soybean plant organs as well as the N balance. The objective of this study

A manipulation of carotenoid metabolism influence biomass partitioning and fitness in tomato

Metabolic Engineering, 2022
Improving yield, nutritional value and tolerance to abiotic stress are major targets of current breeding and biotechnological approaches that aim at increasing crop production and ensuring food security. Metabolic engineering of carotenoids, the precursor of vitamin-A and plant hormones that regulate plant growth and response to adverse growth ...

Fruiting, Morphology, and Architecture of ‘Arbequina’ and ‘Calatina’ Olive Branches

Horticulturae, 2022
Two different olive cultivars grown under a high-density hedgerow system were studied to compare their fruiting and branch architecture features and to determine the possibility to use ‘Calatina’ olive trees for intensive plantings, as a local ...

Comparison of Microbial Communities in the Sediments and Water Columns of Frozen Cryoconite Holes in the McMurdo Dry Valleys, Antarctica

Frontiers in Microbiology, 2019
Although cryoconite holes, sediment-filled melt holes on glacier surfaces, appear small and homogenous, their microbial inhabitants may be spatially partitioned. This partitioning could be particularly important for maintaining biodiversity in holes that
