Abstract:
Potential consequences of climate change on crop production can be studied using mechanistic crop simulation models. While a broad variety of maize simulation models exist, it is not known whether different models diverge on grain yield responses to changes in climatic factors, or whether they agree in their general trends related to phenology, growth, and yield. With the goal of analyzing the sensitivity of simulated yields to changes in temperature and atmospheric carbon dioxide concentrations [CO2], we present the largest maize crop model intercomparison to date, including 23 different models. These models were evaluated for four locations representing a wide range of maize production conditions in the world: Lusignan (France), Ames (USA), Rio Verde (Brazil) and Morogoro (Tanzania).
While individual models differed considerably in absolute yield simulation at the four sites, an ensemble of a minimum number of models was able to simulate absolute yields accurately at the four sites even with low data forcalibration, thus suggesting that using an ensemble of models has merit. Temperature increase had strong negative influence on modeled yield response of roughly 0.5 Mg ha1 per °C. Doubling [CO2] from 360 to 720 lmol mol1 increased grain yield by 7.5% on average across models and the sites. That would therefore make temperature the main factor altering maize yields at the end of this century. Furthermore, there was a large uncertainty in the yield response to [CO2] among models. Model responses to temperature and [CO2] did not differ whether models were simulated with low calibration information or, simulated with high level of calibration information. MenosAbstract:

Abstract. The aim of this study was to evaluate the effect of different aminoethoxyviniglycine (AVG), thidiazuron (TDZ) and prohexadione calcium (P-Ca) rates sprayed at different timing on fruit set, yield, and fruit quality of 'Rocha' pear trees in different climatic conditions of Sothern Brazil. The study was performed in two commercial orchards located in Sao Joaquim, SC, (2015/2016) and Antonio Prado, RS (2016/2017). Plant material consisted of 'Rocha' pear trees grafted onto Pyrus calleryana and quince roorstock 'BA29' in Sao Joaquim and Antonio Prado, respectively. Treatments consisted of AVG, TDZ and P-Ca sprayed at different rates and timins. Truk cross-sectional area increase, fuit set, thinned fruit length, fruit diameter, L/D ratio, seed number, flesh fimmess, and soluble solids content were assessed. Fruit set and yield were consistently increased by AVG in all experiments. Fruit set was not affected by P-Ca 100 mg L-1 Sprayed at full bloom + 7 days after full bloom and TDZ 10mg-1 at full bloom. Fruit size was consistently incrased by TDZ. |
