Abstract:

Extension of the commonly used spring wheat (Triticum aestivum L.)-fallow rotation to include broadleaf crops requires information on their effects on a following wheat crop. We grew a spring wheat test crop on the stubbles of wheat and seven broadleaf crops: desi chickpea (Cicer arietinum L.), dry bean (Phaseolus vulgaris L.), dry pea (Pisum sativum L.), lentil (Lens culinaris L.), mustard (Brassica juncea L.), safflower (Carthamus tinctorius L.), and sunflower (Helianthus annuus L.).

Abstract:

Field studies undertaken at Armidale in 1982-84 demonstrated that the principal factors determining the effect of retained stubble on the growth and yield of wheat were the species of the crop from which the stubble had been derived, the amount and distribution of rainfall and the degree of decomposition that the stubble had undergone prior to the next crop. Stubbles were phytotoxic only prior to leaching by rain or decomposition, with unweathered sorghum stubble proving more inhibitory to wheat than unweathered sunflower, field pea, wheat or oilseed rape stubble.

Abstract:

Grazing crop stubbles affects soil structure, groundcover, and the productivity of subsequent crops, but the cost of this practice is highly variable and not easily compared against the value of feed provided to livestock. To compare with and without grazing stubbles in terms of whole-farm profit and water-use efficiency we created a mixed enterprise farm model using the Agricultural Production Systems Simulator and GRAZPLAN biophysical simulation submodels, and the Model of Integrated Dryland Agricultural System linear programming model. We hypothesised that grazing crop stubbles would increa

Abstract:

Use of urea fertiliser for cereal cropping in south eastern Australia has increased rapidly in recent years to arrest a general decline in grain protein and to increase yields. In conservation cropping systems, crop stubbles provide a source of carbon, which has the potential to retain a portion of the fertiliser nitrogen in the soil. The impact of fertiliser nitrogen was compared under 4 stubble management regimes for efficiency of nitrogen uptake by a wheat crop in a long-term cereal–grain legume rotation. The experiment was established on a duplex red-brown earth in 1985 to compare stubble

Lack of suitable machinery is a major constraint to direct drilling into combine-harvested rice residues due to the heavy straw load, and the presence of loose tough straw deposited by the harvester.

As well as loss of organic matter and nutrients, rice stubble burning causes very serious and widespread air pollution in the north-west Indo-Gangetic Plains, where rice–wheat systems predominate.

Protein modifications by ubiquitin and small ubiquitin-like modifier (SUMO) play key roles in cellular signaling pathways. SUMO-targeted ubiquitin ligases (STUbLs) directly couple these modifications by selectively recognizing SUMOylated target proteins through SUMO-interacting motifs (SIMs), promoting their K48-linked ubiquitylation and degradation. Only a single mammalian STUbL, RNF4, has been identified. We show that human RNF111/Arkadia is a new STUbL, which used three adjacent SIMs for specific recognition of poly-SUMO2/3 chains, and used Ubc13–Mms2 as a cognate E2 enzyme to promote nonpr

Abstract:

Responses of cattle to urea and molasses supplements while grazing cereal crop stubbles were studied in two experiments.In experiment 1,2.5-year-old Friesian cows in early pregnancy grazed an oat stubble (6800 kg DM ha-1) for 12 weeks at a stocking rate of 3.8 cows ha-1. In addition, some were offered liquid supplements of molasses, or urea-molasses. Liveweight gain (mean 18 kg) was not significantly different between treatments during the first 6 weeks. Thereafter, unsupplemented cows lost weight at 1.6 kg day-1 compared with 0.5 kg day-1 for supplemented cows (P(0.05).In experiment 2, 1.5-ye

Abstract:

The Slx5/Slx8 heterodimer constitutes a SUMO-targeted ubiquitin ligase (STUbL) with an important role in SUMO-targeted degradation and SUMO-dependent signaling. This STUbL relies on SUMO-interacting motifs in Slx5 to aid in substrate targeting and carboxy-terminal RING domains in both Slx5 and Slx8 for substrate ubiquitylation. In budding yeast cells, Slx5 resides in the nucleus, forms distinct foci, and can associate with double-stranded DNA breaks. However, it remains unclear how STUbLs interact with other proteins and their substrates. To examine the targeting and functions of the Slx5/Slx8

Abstract:

AbstractIn different parts of the world, the increasing agricultural practice of retaining crop stubble in fields across seasons has led to population increases of soil-dwelling arthropods, primarily detritivorous species. These species typically play a beneficial role in the ecosystem, but some, including the Portuguese millipede (Ommatoiulus moreleti (Lucas)) can be sporadic pests. To assist in better understanding of pest risk, this study examines why O. moreleti feeds on crop seedlings. For lupin, seedling susceptibility appears to be related to plant properties, with greatly different lev

Bacteria were consistently isolated from the root and crown xylem of symptomless field-grown alfalfa plants. Most of the plants tested contained more than one bacterial genus. Pseudomonas spp. accounted for 52% of the 387 isolates identified and the fluorescent pseudomonads were the most frequent bacteria isolated. About 23% of the isolates were Erwinia-like bacteria. Bacterial population ranged from 6.0 × 103 to 4.3 × 104 CFU/g of fresh xylem, and was not affected by plant age or cultivar or by the sampling locations.

Abstract:

In semiarid sandy soil environments there is a dual challenge of carbon and nitrogen (N) limitation that needs to be managed to ensure timely supply of N to crops. Management of N inputs to soil using combinations of legume stubble addition and fertiliser N in cereal systems is essential to meet crop demand and maintain N in soil organic matter. The aim of this study was to assess soil mineral and biological N pools that influence N supply and N uptake of wheat at early growth stages. The recovery of 15N-labelled fertiliser by wheat was evaluated using a factorial combination of either wheat,

Abstract:

Subsoil constraints present a substantial problem for crop production in many agricultural regions. In particular, soils in temperate grain production areas of Australia are often poorly structured due to high content of sodic clay. An alternative to the standard practice of addition of gypsum is to incorporate organic amendments deep into the subsoil. An incubation experiment was performed for 174 days using several organic amendments. These consisted of wheat shoots, lucerne pellets, canola and chickpea stubbles, chicken manure, peat, and sawdust. Gypsum, an inorganic amendment commonly appl

The organic residue position and C/N ratio regulate decomposition rate and, therefore, nitrogen (N) release to the soil. The N<sub>2</sub>O emission from soil is produced by nitrification and denitrification processes. These processes are affected by the mineral N concentration, water filled pore space (WFPS) and soil temperature. The N<sub>2</sub>O emission from soils covered by corn and soybean residues has been little studied so far. The aim of the present study was to evaluate the C/N ratio of corn and soybean residues and their contact degree with the soil on soil

Abstract:

The soil biota consist of a large number and range of micro- and macro-organisms and are the living part of soils. They interact with each other and with plants, directly providing nutrition and other benefits. They regulate their own populations as well as those of incoming microorganisms by biological control mechanisms. Microorganisms are responsible for organic matter decomposition and for the transformations of organically bound nitrogen and minerals to forms that are available to plants. Their physical structure and products contribute significantly to soil structure. Management practice

Comparative studies of drainage and leaching in irrigated cotton (Gossypium hirsutum L.) based cropping systems in Australian Vertosols are sparse. Our objective was to quantify soil water storage, drainage, and leaching in four cotton-based cropping systems sown on permanent beds in an irrigated Vertosol with subsoil sodicity. Drainage was inferred using the chloride mass-balance method, and soil water storage and leaching were measured with a neutron moisture meter and ceramic-cup water samplers, respectively, from September 2005 to May 2011 in an ongoing experiment.

Four field experiments investigated strategies to reduce the negative effects of surface-retained wheat stubble on the emergence, growth, and yield of canola. All experiments compared 3 stubble treatments: (1) no stubble (stubble removed or burnt); (2) stubble-spread (6 t/ha wheat stubble evenly distributed on the surface); and (3) stubble-inter-row (6 t/ha stubble distributed on the inter-rows only). Seedling emergence was reduced in the presence of evenly spread stubble compared with no stubble, and the emerged seedlings had longer hypocotyls, reduced leaf number, and reduced biomass. Reduce

Abstract:

Microtubules and microtubule-associated proteins are fundamental for multiple cellular processes, including mitosis and intracellular motility, but the factors that control microtubule-associated proteins (MAPs) are poorly understood. Here we show that two MAPs—the CLIP-170 homologue Bik1p and the Lis1 homologue Pac1p—interact with several proteins in the sumoylation pathway. Bik1p and Pac1p interact with Smt3p, the yeast SUMO; Ubc9p, an E2; and Nfi1p, an E3. Bik1p interacts directly with SUMO in vitro, and overexpression of Smt3p and Bik1p results in its in vivo sumoylation. Modified Pac1p is
