Implications of quality deterioration for public foodgrain stock management and consumers in Bangladesh por Dorosh, Paul A., Farid, Naser

“…Analysis of the costs and benefits of alternative stock targets based on calculations of the minimum age of stock on a monthly basis indicates that moderate increases in the size of stock (e.g. 200 thousand tons), lead to only small net marginal outlays. However, unless procurement and distribution are also raised, the age and quality of the stock for distribution deteriorates, resulting in significant losses to program recipients.…”

Transdisciplinary research approaches for crop science research: theory, practice, and implications for research design por Amoak, Daniel, Najjar, Dina, Belcher, Brian

“…Success needs to be measured in gains from multiple traits, including climate resilience (drought or heat tolerance), nutritional value, value to women farmers or the marginalized, and market traits valued by a range of consumers, as well as the necessary attention to productivity and income-generation (De Grandis & Efstathiou, 2016; FAO, 2023). …”

Interactions between rodents and weeds in a lowland rice agro‐ecosystem: the need for an integrated approach to management por Htwe, Nyo Me, Singleton, Grant R., Johnson, David E.

“…In temperate cereal systems, seeds of grass weeds can be an important food source for rodents and weed cover along crop margins provides important refuge for rodents. In 2012 and 2013, a replicated study (n = 4) in Bago, Myanmar compared 4 treatments (rodents and weeds; no rodents and weeds; rodents and no weeds; no rodents and no weeds) each of 0.25 ha in transplanted rice. …”

Global nitrogen budgets in cereals: A 50-year assessment for maize, rice, and wheat production systems por Ladha, J.K., Tirol-Padre, A., Reddy, C.K., Cassman, K.G., Verma, Sudhir, Powlson, D.S., van Kessel, C., de B. Richter, Daniel, Chakraborty, Debashis, Pathak, Himanshu

“…Crop residues and seed contribute marginally. Our scaling-down approach to estimate the contribution of non-symbiotic N2fixation is robust because it focuses on global quantities of N in sources and sinks that are easier to estimate, in contrast to estimating N losses per se, because losses are highly soil-, climate- and crop-specific.…”
