How have foreign exchange market distortions and conflict affected agricultural production incentives in Myanmar? by Myanmar Agrifood Program for Strategy and Analysis

“…. • Despite the significant disincentives brought about by conflict, the agricultural sector has shown surprising resilience over the recent conflict period, seemingly linked to advantageous international price developments for farmers: international rice prices increased by 27 percent while urea prices decreased by 52 percent between August 2022 and May 2024. • While these international evolutions have partly mitigated the impact of the conflict on farmers’ profitability, the impacts of these price developments on consumers in Myanmar have, however, been severe. …”

Inoculation with Azospirillum brasilense as a strategy to reduce nitrogen fertilization in cultivating purple maize (Zea mays l.) in the Inter-andean valleys of Peru by Condori Ataupillco, Tatiana, Alarcón Romani, Susan, Huasasquiche Sarmiento, Lucero, García Blásquez, Cayo, Padilla Castro, César, Velásquez Mantari, José, Solórzano Acosta, Richard Andi

“…Treatments comprised two inoculation levels (control without inoculation and inoculation with A. brasilense) under five nitrogen doses (0, 30, 60, 90, and 120 kg・ha−1, applied as urea). Inoculation with A. brasilense resulted in a 10.5% increase in plant height, a 16.7% increase in root length, a 21.3% increase in aboveground fresh biomass, a 30.1% increase in root fresh biomass, and a 27.7% increase in leaf nitrogen concentration compared to the no inoculated control. …”

Ecophysiological traits in maize hybrids and their parental inbred lines: Phenotyping of responses to contrasting nitrogen supply levels by D'Andrea, Karina Elizabeth, Otegui, María Elena, Cirilo, Alfredo Gabriel, Eyherabide, Guillermo

“…Phenotyping included the evaluation of 26 morpho-physiological attributes for 6 maize inbred lines and 12 derived hybrids, cropped in the field at contrasting N supply levels (N0: no N added; N400: 400 kg N ha−1 applied as urea) during three growing seasons. Tested genotypes differed in the response to reduce N supply for most measured traits. …”
