Identification of putative CONSTANS-like genes from the de novo assembled transcriptome of leek

open access: yesBiologia Plantarum, 2018
Leek is an economically important vegetable. In model plants, the CONSTANS (CO) and CONSTANS-like (COL) genes play central roles in plant flowering modulation.

Biodegradable plastic film mulch increases the mineralisation of organic amendments and prevents nitrate leaching during the growing season in organic vegetable production

open access: yesJournal of Sustainable Agriculture and Environment, Volume 3, Issue 3, September 2024.
Abstract Introduction Organic vegetable production relies on inputs of organic forms of nitrogen (N). This presents a challenge as it needs to be mineralised by the soil microbial community. Difficulties matching the timing and rate of organic N amendments to crop demand could potentially lead to high rates of nitrate leaching.

Insecticidal activity of a protein extracted from bulbs of Phycella australis Ravenna against the aphids Acyrthosiphon pisum Harris and Myzus persicae Sulzer [PDF]

open access: yes, 2016
Aphids cause significant losses in many agricultural crops and in many cases cause repeated insecticide sprays, which increase the risk of resistance. Therefore, other alternatives are needed to control them.

Organic farming improves soil carbon pools and aggregation of sandy soils in the Brazilian semi‐arid region

open access: yesSoil Use and Management, Volume 40, Issue 3, July 2024.
Abstract Organic agriculture can be a feasible alternative to improve soil organic carbon contents, but its effects on different carbon pools and the benefits for soil quality in sandy soils of warm climates are still poorly understood. This study aimed to assess the influence of organic and conventional farming systems on carbon pools, and its effects

Management of vegetable crop residues for reducing nitrate leaching losses in intensive vegetable rotations [PDF]

open access: yes, 2012
Crop residues of field vegetables are often characterized by large amounts of biomass with a high N-content. Despite low soil temperatures during autumn, high rates of N mineralization and nitrification still occur causing important N-losses through ...
