Garlic extract improves budbreak of the 'Niagara Rosada' grapevines on sub-tropical regions Extrato de alho melhora a superação da dormência de videiras 'Niagara Rosada' em regiões subtropicais [PDF]

open access: yesCiência Rural, 2010
In the regions with mild winters, usually the chilling requirements for bud dormancy release of grapevines are not fulfilled, and only the highly toxic products CaCN2 (calcium cyanamide) and H2CN2 (hydrogen cyanamide) are recommended in conventional ...

Cyanamide route to calcium–manganese oxide foams for water oxidation [PDF]

open access: yesDalton Transactions, 2013
In nature, photosynthetic water oxidation is efficiently catalysed at a protein-bound μ-oxido Mn4Ca cluster. This cluster consists of earth abundant, non-toxic elements and serves as a paragon for development of synthetic catalysts. In this study we developed porous calcium-manganese oxides with a unique foam-like nanostructure prepared via a facile ...

Biostimulants as a Response to the Negative Impact of Agricultural Chemicals on Vegetation Indices and Yield of Common Buckwheat (Fagopyrum esculentum Moench)

open access: yesAgriculture, 2023
Weed control during common buckwheat cultivation is hindered by the crop’s high sensitivity to agrochemicals. This study evaluates whether biostimulants (Asahi SL, Kelpak SL, B-Nine) could reduce the adverse effect of abiotic stress caused by these ...

Effect of Calcium Cyanamide as an Alternative Nitrogen Source on Growth, Yield, and Nitrogen Use Efficiency of Short-Day Onion

open access: yesAgronomy, 2023
Effective nitrogen (N) management in agriculture is vital to optimize crop growth and yield while minimizing environmental impact. Conventional nitrogen (N) sources, such as urea, have limitations in promoting growth and reducing N leaching.

Managing clubroot disease (caused by Plasmodiophora brassicae Wor.) by exploiting the interactions between calcium cyanamide fertilizer and soil microorganisms [PDF]

open access: yes, 2017
Calcium cyanamide is a nitrogenous fertilizer used predominantly for over a century in field and glasshouse vegetable and salad production. This review draws together for the first time knowledge concerning the biological properties of the compound that ...

Measures to prevent foam formation in the anaerobic digestion of sugar beet in biogas plants

open access: yesLandtechnik, 2017
The occurrence of persistent foaming is observed in many anaerobic digesters that have sugar beet as their feedstock. The formation of foam entails a significant risk of damage to biogas plants, as gas pipes can become blocked.

Performance of ‘Maxi Gala’ apple trees as affected by budbreak promoters, in São Joaquim-SC

open access: yesRevista Brasileira de Fruticultura, 2018
The application of rest breaking agents to compensate the lack of chilling is a common practice in apple orchards in Southern Brazil. However, its necessity in areas of greater chilling accumulation has been questioned over the years.
