Effect of tolerance to Septoria tritici blotch on grain yield, yield components and grain quality in Argentinean wheat cultivars
(Elsevier, 2016-12)
Septoria tritici blotch (STB) caused by Zymoseptoria tritici (Mycosphaerella graminicola) is a major disease of wheat worldwide due to significant losses in grain yield and quality. Disease tolerance is the ability to ...
Analysis of sink/source relations in bread wheat recombinant inbred lines and commercial cultivars under a high yield potential environment
(Elsevier Science, 2018-02)
Grain yield in wheat is generally considered to be sink-limited during grain filling. But is this limitation inherent to the crop species or a consequence of the breeding process? A way to ascertain this is by using genetic ...
Estimation of irrigated oats yield using spectral indices
(2019-08-20)
Spectral indices such as normalized difference vegetation index (NDVI) and Falker chlorophyll index (FCI) are valuable tools for estimating crop yield. However, there remains a need to define the best phenological stages ...
Development and grain yield of common bean cultivars according to sowing season
(2019-01-01)
The cycle and grain yield of bean crops can be influenced by several factors, among them sowing season and bean cultivar. The objective of this work is to evaluate the development, production components, and grain yield ...
Maize grain yield components and source-sink relationship as affected by the delay in sowing date
(Elsevier Science, 2016-11)
Delaying maize (Zea mays L.) sowing date can diminish grain yields through reductions in the number, size and activity of growing grains (sink strength) and/or reductions in the assimilate supply (source capacity) to grains ...
Genotype and genotype-by-environment interaction effects for grain yield and grain size of quinoa (Chenopodium quinoa Willd.) as revealed by pattern analysis of international multi-environment trials
(Elsevier Science, 2004-10)
The size and nature of the genotype (G) and genotype×environment (G×E) interaction effects for grain yield, its physiological determinants, and grain size exhibited by the Andean grain crop quinoa at low latitudes were ...
Caracterização ontogenética e agro-fisiológica de cultivares modernas de trigo (Triticum aestivum L.)
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Ciências AgráriasAgronomiaUTFPR, 2017-11-22)
Knowing the processes responsible for high yields of grains in different genotypes available in the market is an essential step for the selection of more productive genotypes. The objectives of this study were: a) to ...
Modelled yield and water use efficiency of maize in response to crop management and Southern Oscillation Index in a soil-climate transect in Argentina
(Elsevier Science, 2012-10)
Maize responses to individual management factors have been widely investigated but studies of higher-order interactions involving multiple factors are rare. This paper investigates the responses of grain yield and water ...
Understanding grain yield responses to source-sink ratios during grain filling in wheat and barley under contrasting environments
(Elsevier, 2013-08-20)
A better understanding of the effects of different source?sink ratio during the grain filling period on grain growth may be relevant in order to further increase cereal grain yield. The main objective of the present work ...
