Influence of micronutrients on dry matter yield and interaction with other nutrients in annual crops.
(Pesquisa Agropecuária Brasileira, Brasília, v. 37, nº 12, p.1765-1772, dez. 2002., 2011)
Parametric and nonparametric statistical modelling of crop yield: implications for pricing crop insurance contracts
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2008)
This article considers alternative methods to calculate the fair premium rate of crop insurance contracts based on county yields. The premium rate was calculated using parametric and nonparametric approaches to estimate ...
Inclusion of cover crops in cropping sequences with soybean predominance in the southeast of the Humid Argentine Pampa
(2013)
The incorporation of a cover crop (CC) may be an alternative to increase soil carbon (C) and nitrogen (N) supply in crop sequences with a high frequency of soybean. The aims of this study were (i) to determine shoot biomass ...
A systems-level yield gap assessment of maize-soybean rotation under high- and low-management inputs in the Western US Corn Belt using APSIM
(Elsevier, 2019-08)
Quantifying yield gaps (potential minus actual yield) and identifying management practices to close those gaps is critical for sustaining high-yielding production systems. The objectives of this study were to: 1) calibrate ...
Functional crop types are more important than diversity for the productivity, profit and risk of crop sequences in the inner Argentinean Pampas
(Elsevier, 2022-02)
CONTEXT: Over the last 250 years, many natural ecosystems in South America, including the Inner Pampas of Argentina, evolved into extremely simplified agroecosystems. In the last 25 years, simplified soybean-based crop ...
Projected climate change threatens pollinators and crop production in Brazil
(Public Library of Science, 2017-08-09)
Animal pollination can impact food security since many crops depend on pollinators to produce fruits and seeds. However, the effects of projected climate change on crop pollinators and therefore on crop production are still ...

Lime and gypsum combination improves crop and forage yields and estimated meat production and revenue in a variable charge tropical soil
(2019-12-01)
In tropical integrated crop-livestock under no-till (NT) systems, the surface application/reapplication of lime and/or gypsum can reduce re-acidification rate of the soil and improve plant nutrition, crop yields, and ...
