Ants in tropical irrigated rice: distribution and abundance, especially of Solenopsis geminata (Hymenoptera: Formicidae) por Way, M.J., Islam, Z., Heong, K.L., Joshi, R.C.

“…This ant was scarce or absent in relatively undisturbed well-vegetated bunds where Pheidole spp. were sometimes common and where up to 14 different species were recorded in bunds of a single field. Colonies were spaced out along the bunds where foraging territories sometimes overlapped, except for those of the competing dominants S. geminata and Pheidole spp. …”

Geographic Distribution of Common and Dwarf Bunt Resistance in Landraces of Triticum aestivum subsp. aestivum por Bonman, J. Michael, Bockelman, Harold E., Goates, Blair J., Obert, Don E., McGuire, Patrick E., Qualset, Calvin O., Hijmans, Robert J.

“…Wint. and T. laevis Kühn, and 8167 to dwarf bunt (DB) caused by T. controversa Kühn with respect to geographic origin, relationship to color of awn, glume, and kernel of accessions, and phenotypic variation within areas of high frequency of resistance. A clear center of concentration was evident for CB resistance extending from Serbia and Montenegro through Macedonia, Turkey, and Iran with the highest frequency of resistance occurring in Kosovo province in Serbia and Montenegro (36%) and Bakhtaran province in Iran (40.8%). …”

Role of organic acids in phosphate mobilization from iron oxide por Johnson, Sarah E., Loeppert, Richard H.

“…At 3/4 of the adsorption maximum, ligand exchange contributed to a greater extent to P release. Under low P‐fertility conditions, organic‐acid exudation would be more effective at increasing P availability in soils dominated by poorly crystalline than well‐crystalline Fe oxides.…”

Global Millet Trends, Outlook, Challenges, and Opportunities por Deevi, Kumara Charyulu, Swamikannu, Nedumara, Padmanabhan, Jyosthnaa

“…The major socio-economic challenges in case of pearl millet are follows: farmers grow it for self-sufficiency purpose rather than for market, thinly traded globally, low market demand, and lack of sufficient value addition opportunities, etc. Millet farming has a significant role in tackling the challenges of climate change, environmental degradation, and malnutrition due to its low water requirement and reduced dependency on synthetic fertilizers, etc., 2023 being the “International Year of Millets” (IYM) creating awareness among consumers about its nutritive value and other health benefits globally.…”
