  2. Soybean yield and water productivity gaps associate with ENSO-dependent effects of fungicide, sowing date and maturity group por Videla Mensegue, Horacio Rogelio, Cordoba, Mariano Augusto, Caviglia, Octavio, Sadras, Victor Oscar

    Publicado 2024
    “…The reported soybean yield gap calculated as the difference between water-limited potential yield (Yw) and actual on-farm yield in the Argentinean Pampas averaged 1260 kg ha−1 or 32% of Yw. Actual water productivity (the ratio between actual yield and water use), the upper limit of water productivity (WPw), and the water productivity gap (WPg) have not been quantified, and their relationships with yield gap are unknown. …”

  4. Detoxification response in honey bee larvae exposed to agricultural intensification por Macri, Ivana Noelia, Latorre Estivalis, Jose M., Nery, Denise, Derguy, María Rosa, Cristos, Diego Sebastian, Zavala, Jorge Alberto, Farina, Walter Marcelo

    Publicado 2025
    “…Hives placed in an agricultural setting located in the region of the Argentine Pampas were studied. Changes in the expression levels of insect cytochrome P450s, enzymes involved in the detoxification of xenobiotics, and the presence of pesticides in hive products at different times of crop management were evaluated. …”

  8. Do soil carbon sequestration and soil fertility increase by including a gramineous cover crop in continuous soybean? por Beltran, Marcelo Javier, Galantini, Juan Alberto, Salvagiotti, Fernando, Tognetti, Pedro Maximiliano, Bacigaluppo, Silvina, Sainz Rozas, Hernan Rene, Barraco, Miriam Raquel, Barbieri, Pablo

    Publicado 2021
    “…The effects of including a winter gramineous cover crop (CC) in continuous soybeans were evaluated in three long-term experiments (8 yr) on one coarse-textured soil and two finetextured soils in the Pampas region of Argentina. The impacts of CC on soil C sequestration, soil nutrient availability, soil organic C (SOC), and N contents of soil particle size fractions were also determined. …”
