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...

Sugarcane (Saccharum officinarum L.) is a multi-purpose crop, mainly planted in South-western (SW) parts of Iran. However, the capability of sugarcane farms to sequestrate carbon into soil and plant is not well documented. In this research, the carbon sequestration in sugarcane plant and soil in a ratooning traditional cultivation system at the Amirkabir Sugarcane Agro-Industry Complex...

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...

Yield loss of ratoon crops caused by the rolling damage to left stubble from mechanically harvesting main has been reported in previous studies. However, limited attention paid identify effect mechanical crop on yield a non-rolled zone (NRZ) crop. A two-year field experiment rice with two harvest methods (mechanical harvesting: MEH; manual MAH) was conducted whether there is border NRZ, and eva...

Ratooning is an important cultivation practice in sugarcane production around the world, with underground buds on remaining stalk acting as source for establishment of a subsequent ratoon crop. However, optimal depth cutting during harvest terms yield and root growth remains unknown. We carried out two-year field study to determine effects three depths (0, 5 10 cm below surface) cane yield. Res...
