|Title:||The effect of soil pH on chickpea ('Cicer arietinum') genotype sensitivity to isoxaflutole||Contributor(s):||Datta, Avishek (author); Sindel, Brian Mark (author) ; Kristiansen, Paul (author) ; Jessop, Robin Stephen (author); Felton, Warwick (author)||Publication Date:||2008||DOI:||10.1007/s11104-007-9430-2||Handle Link:||https://hdl.handle.net/1959.11/3590||Abstract:||A glasshouse experiment was conducted to investigate the effect of soil pH on chickpea ('Cicer arietinum') tolerance to isoxaflutole applied pre-emergence at 0, 75 (recommended rate) and 300 g a.i. ha⁻¹. For this study, the variables examined were two desi chickpea genotypes (97039-1275 as a tolerant line and 91025-3021 as a sensitive line) and four pH levels (5.1, 6.9, 8.1, and 8.9). The results demonstrated differential tolerances among chickpea genotypes to isoxaflutole at different rates and soil pH levels. Isoxaflutole applied pre-emergence resulted in increased phytotoxicity with increases in soil pH and herbicide rate. Even the most tolerant chickpea genotype was damaged when exposed to higher pH and herbicide rates, as indicated by increased leaf chlorosis and significant reductions in plant height, and shoot and root dry weight. The effects were more severe with the sensitive genotype. The susceptibility of chickpea to this herbicide depends on genotype and soil pH which should be taken into account in breeding new lines, and in the agronomy of chickpea production.||Publication Type:||Journal Article||Source of Publication:||Plant and Soil, 303(1-2), p. 49-54||Publisher:||Springer||Place of Publication:||Amsterdam, The Netherlands||ISSN:||0032-079X||Field of Research (FOR):||070308 Crop and Pasture Protection (Pests, Diseases and Weeds)||Socio-Economic Outcome Codes:||829899 Environmentally Sustainable Plant Production not elsewhere classified||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 334
