abstract soil compaction is a main factor that reduces the cane yield in sugarcane fields, in southwest of iran, especially in ratoon cropping system. therefore, sub-soiling practices could alleviate adverse effects of compaction and increased yield. in according to this aim, a study was to evaluate the effect of  ratooning practice systems consisting of control (no subsoiler), two and four sha...

Rice (Oryza sativa L.) ratooning has attracted attention due to its higher yield potential compared with conventional methods. Here, field experiments were conducted in southwestern Japan 2019 and 2020 determine the effects of cultivar (‘Takanari’, an indica cultivar, ‘Koshihikari’, a japonica cultivar) harvest time first crop (early late) on grain yields second crops rice ratooning. For Koshih...

Rhizomes are organs of fundamental importance to plant competitiveness and invasiveness. We have identified genes expressed at substantially higher levels in rhizomes than other plant parts, and explored their functional categorization, genomic organization, regulatory motifs, and association with quantitative trait loci (QTLs) conferring rhizomatousness. The finding that genes with rhizome-enr...

Positive plant-soil feedback depends on beneficial interactions between roots and microbes for nutrient acquisition; growth promotion; and disease suppression. Recent pyrosequencing approaches have provided insight into the rhizosphere bacterial communities in various cropping systems. However; there is a scarcity of information about the influence of root exudates on the composition of root-as...
