In this study, the performance of two empirical models i.e. AquaCrop and artificial neural network models for simulating the grain yields of two most cultivated varieties including the Shirudi (high-yielding) and Tarom (low-yielding) in three contrasting soil series with different fertilizer managements, were calibrated and validated during 2016 and 2017 rice growing seasons for 459 paddy fields in Mazandaran province, northern Iran. Both models were tested by correlation (R2 ), normalized root mean square error (nRMSE) and coefficient of residual mass (CRM). Results indicate that the performance of both models were affected by the rice cultivar, soil type and soil fertilizer management for both calibration and validation datasets. The ability of both models proved to be satisfactorily applicable for spatial simulation of rice yields in northern Iran, but AquaCrop model was superior. The higher accuracy was observed in AquaCrop for the Shirudi cultivar (R2 =0.89; nRMSE=5.87%; CRM=0.03) compared to the Tarom (R2 =0.67; nRMSE=10.41% and CRM=0.04) for 2017 dataset demonstrating that the AquaCrop has more performance for high-yielding cultivar. Two models had lower accuracy in Esmaeilkola soil series with deep clay soil texture. The best accuracy was observed in paddy fields with optimum fertilizer managements for both models. Overall, it is possible to suggest that AquaCrop model could be used to simulate the spatial distribution of rice grain yield with an acceptable accuracy at province-scale and is applicable for local climate change related scenarios.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71120156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to assess the relationship between climatic factors and maize yield, grain moisture at harvest and resistance of plants to broken and stalk lodging, with reference to maize hybrids created at the Agricultural Research and Development Station Turda (ARDS), in the centre area of Romania. The purpose of this study was to detect trends in the yield ability of 35 maize hybrids (18 historical and 17 recently released) and the possible association with weather trends. A significant increase in temperature both during vegetative growth and grain filling was observed, while rainfall presented a decrease in the critical period of flowering and grain-filling, during the last two decades (2000-2020), with large year to year variations. During the analyzed period, yields of the historical hybrids showed a reduction trend from -72 kg/ha/year for FAO groups 210-300, to -272 kg/ha/year for FAO groups over 300. The average yield of recently released hybrids showed an increasing trend from +91 kg/ha/year for FAO 300-hybrids, to +215 kg/ha/year for FAO groups 210-300. This suggests that genetic progress reflected in the release of new maize hybrids was able to counteract the negative effect of climate change seen on the yield of the historical hybrids. The yield difference between recently released hybrids and the historical ones showed the rate of genetic progress of +171 kg/ha/year for very early hybrids, +116 kg/ha/year for early hybrids, and +275 kg/ha/year for semi-early hybrids.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71119984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stability of grain yield performance of 18 barley genotypes was evaluated at 5 locations for 3 years in the rainfed conditions and it was studied through 25 nonparametric stability methods. Four nonparametric tests indicated highly significant GE interaction due to differential performance of genotypes across fifteen environments. Regarding mean yield and six Hühn’s statistics, genotype G12 (1946 kg ha-1) was the most favorable genotype while based on the RN1, G4, G10 and G11 were the most stable genotypes. Genotypes G4, G8 and G10 were the most favorable genotypes according to rank-sum while genotypes G2, G13 and G18 were the most favorable genotypes based on nonparametric superiority. The relative interactivity index identified G4, G16 and G8 as the most stable genotypes while the genotypic classification identified G1, G2, G13 and G18 as the most stable genotypes. Clustering of the nonparametric stability methods indicated that there were two groups with different static and dynamic characteristics. In this study, five nonparametric stability methods as GC, FM, PA, RN2 and KR2 were associated with high grain yield and reflected the dynamic concept of stability, but the other twenty nonparametric stability methods were not positively correlated with yield and characterized a static concept of stability. Finally, genotypes genotype G13 (2114.13 kg ha-1) and G18 (2062.69 kg ha-1) were found to be the most favorable genotypes and are thus recommended for commercial release in semiarid areas of Iran.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71119990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In present research have been assessed 8 yield related traits at 25 sunflower hybrids, in two growing season (2019, 2020), under different weather conditions in Soroca district from the northeast of the Republic of Moldova. The principal component analysis, correlative and multicollinearity statistics highlighted their clustering according to different categories: commercial, experimental and in testing phase for hybrid performance, indicating the diverse nature of hybrids. The correlation profile of yield related traits at the commercial hybrids contrasts with that of the tested and experimental hybrids which in both evaluated years, is more heterogeneous in context of the strength and direction of correlation. The parameters achene weight per head and number of achene per head, followed by seed yield and head diameter have the highest degree of variation related to growing season. Most negative correlations are found for correlation pairs with variables 1000 seed weight and hectolitre mass of seeds, which are moderate and high for the tested and experimental hybrids, and predominantly low for the commercial ones. The commercial hybrids were more sensitive to the drought stress of the 2020 growing season, responding by a greater decrease of the majority of analyzed agronomic indices. At the same time the correlations between different traits indicated a pattern similar to previous year. Contrary, the experimental hybrids and those in the testing phase showed small changes in the values of agronomic traits that suggest a greater tolerance to drought conditions, as well as less correlations between different indices.
