Bayesian ratemaking procedure of crop insurance contracts with skewed distribution
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2009)
Over the years, crop insurance programs became the focus of agricultural policy in the USA, Spain, Mexico, and more recently in Brazil. Given the increasing interest in insurance, accurate calculation of the premium rate ...

Modelling water productivity for ecological intensification of crop sequences in the Inner Argentinean Pampas
(Elsevier, 2021-09)
The design of crop sequences based on ecological intensification (EI) may help to restore lost agroecosystem services and to increase resource use efficiency. Our aim was to evaluate, using a modelling approach, the impact ...
Metaheuristics for a crop rotation problem
(2014)
This paper presents a mathematical model adapted from literature for the crop rotation problem with demand constraints (CRP-D). The main aim of the present work is to study metaheuristics and their performance in a real ...
Sustainable vegetable crop supply problem
(ELSEVIER SCIENCE BV, 2010)
We consider an agricultural production problem, in which one must meet a known demand of crops while respecting ecologically-based production constraints. The problem is twofold: in order to meet the demand, one must ...
Development and validation of a simulation model for hairy vetch (Vicia villosa Roth) self-regeneration under different crop rotations
(Elsevier, 2019-04)
Hairy vetch (HV, Vicia villosa Roth) is a winter annual legume cultivated for pasture grazing, in crop rotations with cereal crops under semi-arid conditions. The inclusion of HV increases soil nitrogen, thus contributing ...
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 ...
FUZZY MODELING OF THE EFFECTS OF DIFFERENT IRRIGATION DEPTHS ON THE RADISH CROP. PART I: PRODUCTIVITY ANALYSIS
(Associação Brasileira de Engenharia Agrícola, 2021-06-25)
The productivity of a crop is related to the water demand inserted in its development. The measurement of water and its optimization directly influences the final costs of crop production for agricultural producers. In ...
Estimation of the genetic coefficients of the ceres-maize model for the simulation of yield by non-destructive methods
(Colegio de Postgraduados, 2023)
