• Canola is one of the most profitable crops available to grain growers in southern and western Australia and rotations have been adapted to accommodate it. • Canola provides large yield benefits to subsequent cereal crops by providing an effective disease break. • Canola was often grown as the first crop after pasture but now canola is often used more intensively in rotations, posing problems ...

The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama, is one of the most serious citrus pests worldwide due to its role as vector of huanglongbing or citrus greening disease. While some optimal plant species for ACP oviposition and development have been identified, little is known of the influence of host plants on ACP size and shape. Our goal was to determine how size and shape of ACP win...

Lime [Citrus aurantifolia (Cristm.) Swingle] is a Citrus species that is a popular ingredient in many cuisines. Some citrus plants are known to originate in the area ranging from northeastern India to southwestern China. In the current study, we characterized and compared limes grown in Bhutan (n = 5 accessions) and Indonesia (n = 3 accessions). The limes were separated into two groups based on...

The lime pretreatment process for rice straw was optimized to enhance the biodegradation performance and increase biogas yield. The optimization was implemented using response surface methodology (RSM) and Box-Behnken experimental design. The effects of biodegradation, as well as the interactive effects of Ca(OH)2 concentration, pretreatment time, and inoculum amount on biogas improvement, were...

A research worker in soil chemistry accustomed to cbfidk$ions in England is soon conscious in New Zealand of many anomalies in the position that liming occupies in local farming practice. In the major%y of districts in Great Britain the periodical application of lime is an establish& practice, and when this practice is neglected the failure of crops or of pasture is quickly notciceable. Moreove...

It is scarcely necessary to emphasize the .j important part played by fleas in the dissemina; tion of plague. The experimental researches of the Indian Plague Commission (1906) have definitely established the transmission of bubonic plague from rat to rat, from rat to man, and from man to man by the agency of rat fleas. Though over 25 species of Xcnopsylla are known to entomologists, only three...

This study evaluates the feasibility of using the grass species Rendlia altera, Monocymbium ceresiiforme, Cynodon dactylon, and amendments (compost and lime) for the phytostabilisation of soils contaminated by Cu in the province of Katanga (Democratic Republic of Congo). Species were grown on control and Cu-contaminated plots (artificially contaminated with 2,500 mg kg(-1) Cu) unamended (NA), a...

We analyzed the reduced-representation genome sequences of Citrus species by double-digest restriction site-associated DNA sequencing (ddRAD-Seq) using 44 accessions, including typical and minor accessions, such as Bhutanese varieties. The results of this analysis using typical accessions were consistent with previous reports that citron, papeda, pummelo, and mandarin are ancestral species, and...
