Background Pesticide application is the dominant control method for arthropod pests in broad-acre arable systems. In Australia, organophosphate pesticides are often applied either prophylactically, or reactively, including at higher concentrations, to control crop establishment pests such as false wireworms and earth mite species. Organophosphates are reported to be disruptive to beneficial spe...

Canola (Brassica rapa) is an oilseed crop that is related to broccoli (Brassica oleracea var Italica) and turnip (Brassica campestris var Rapifera). The name ‘canola’ actually stands for ‘Canadian oil, low acid’. Canola’s low erucic acid content differentiates it from rapeseed (Brassica napus) and is sometimes referred to as LEAR or ‘low erucic acid rapeseed.’ Canola seed contains about 40% oil...

Nutrient digestibility and the effect of high dietary inclusion of canola meals from Brassica napus black (BNB) and Brassica juncea yellow (BJY) on growing and weaned pigs performance were determined. In Exp.1, 6 ileal cannulated barrows (initial BW = 20.7 ± 1.5 kg) were used to determine the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of AA in BNB and BJY. Pig...

this study was conducted to investigate economic aspect and some soil properties in different crop rotations of wheat in dryland conditions in sararood - kermanshah during six years 2006-2012. the experiment carried out based on randomized complete block design (rcbd) with four replications in two neighbor sites. treatments were wheat-wheat, fallow - wheat, chickpea-wheat, vetch-wheat and saffl...

Boron (B) is essential to growth at low concentrations and limits growth and yield when in excess. Little is known regarding plant response to excess B and salinity occurring simultaneously. In this study, two models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB), originally proposed to explain plant response to nutrients only, were modified to evaluate canola yield response to combined le...

Irrigated winter crops can reduce input demands when compared with irrigated summer cropping systems in the Mediterranean area. The sustainability of these be further improved resorting to diverse rotations, but also fertilisation digestate, a by-product from anaerobic digestion organic waste. Post-treatments such as drying and acidifying improve fertiliser value this product. In study, we comp...

long term use of fallow in wheat-based cropping system of dry and semi-dry lands can increase erosion and decrease soil fertility. legumes as substituting crops for fallow could improve sustainability in this area. this study was conducted to evaluate the substituting of some legumes for fallow in a 2-yr wheat rotation at research stations in north khorasan province (natural resources research ...

Cover crops are promoted to increase soil organic carbon (SOC) storage and improve biological health in agricultural systems. However, cover crop effects on microbial communities – key regulators of SOC nutrients functioning not clear semiarid environments. This study investigated the response community structure enzyme activities integration under limited-irrigation winter wheat (Triticum aest...
