The critical period of weed control in faba bean and chickpea in Mediterranean areas
2013
Weeds are often the major biological constraint to growing legume crops successfully, and an understanding of the critical period of weed control (CPWC) is important for developing environmentally sustainable weed management practices to prevent unacceptable yield loss. Therefore, we carried out two field experiments to identify the CPWC for two grain legume crops traditionally grown in Mediterranean areas: chickpea and faba bean. The experiments were conducted at two sites both located in the Sicilian inland (Italy). In chickpea, when weeds were left to compete with the crop for the whole cycle, the grain yield reduction was on average about 85% of the weed-free yield, whereas in faba bean…
The onset of the rainy season and farmers’ sowing strategy for pearl millet cultivation in Southwest Niger
2011
A multi-year (2004-2009) field survey of on-farm sowing practices in 10 villages located in south-west Niger close to Niamey, is analysed to investigate the relationships (i) between rainfall and the sowing date of pearl millet and the risk of sowing failure, (ii) between sowing and meteorological/agro-climatic onset dates, (iii) between sowing/onset dates, and simulated and observed yield/biomass at the end of the season. Even if some villages sow without any synchronous or anterior rainfall, most parcels (73% out of the 1551 available cases) are sown during and just after a 2-day wet spell receiving at least 10 mm. In fact, there is a strong correlation (r = 0.82-0.95 depending on onset d…
Analysis of the relationship between start of the rainy season and farmer's sowing strategy in the Niamey area and its impacts on the pearl millet yi…
2009
International audience; Relationship between start of the rainy season and farmer's planting date have been analysed at local scale through in situ daily rainfall records and agronomical measurement provided by on-farm survey at plot scale for 10 villages network located on the mesoscale AMMA-CATCH Niger site during the 2004-2007 rainy seasons. Many classical empirical methods of monsoon onset dectection (e.g. Benoit, Kowal, Sivakumar, Ati, Marteau, Balme, Sultan) and numerical methods based on crop model SARRAH have been compared to the observed farmer's sowing date. Results show that SARRAH and Balme mean onset date are close to sowing date. But spatial and temporal variability of the sow…
Efficacy of spot form of net blotch suppression in barley from seed, fertiliser and foliar applied fungicides
2022
Abstract Spot form of net blotch (SFNB), caused by Pyrenophora teres f. maculata is a prevalent and damaging foliar disease of barley (Hordeum vulgare). Fungicides are commonly used to manage SFNB infection and reduce production loss in susceptible varieties. This study determined the efficacy of suppression of SFNB and associated grain yield and quality improvements from application of fungicides to seed, fertiliser and/or foliar treatments. Eight field experiments were conducted in south-eastern Australia during 2016–2018. Two experiments compared single applications of different commercially available seed, fertiliser and foliar fungicides. Six experiments evaluated different growth stag…
Association of SNP markers with pea grain protein and grain yield traits in Italy : preliminary results
2013
Grain yield and quality are the main economically important traits in breeding of field pea (Pisum sativum L.). The objective of our work was investigating trait-marker associations in elite pea germplasm, with the final aim to develop marker-assisted selection procedures for these traits. The genetic base for this study was represented by three connected recombinant inbred line (RIL) populations obtained from paired crosses between three genotypes (the varieties Attika, Isard and Kaspa) which featured different geographical origin and outstanding adaptation to Italian cropping environments. At least 86 F7 lines per RIL generated by single-seed descent were evaluated for grain yield, plant …
Ex situ evaluation of grain yield in local landraces of faba bean (Vicia faba L.) from Serbia
2013
International audience; Faba bean (Vicia faba L.) originated in Central Asian centre of diversity. Faba bean is one of the most ancient cultivated plant species in the world, along with several other grain legumes, and cereals. Numerous archaeobotanical fi ndings, supported by rich linguistic evidence (1), witness its early and rapid distribution during Neolithic from Near East to Europe, North Africa and Central and East Asia and an important role it had in everyday diets of the ancestors of modern Old World nations. Today, faba bean is one of the most important annual legume crops for human consumption, animal feeding and for non-food purposes. Conservation and sustainable utilisation of …
