Boron deficiency was first recorded in Australia in the 1930s in apple trees growing in Tasmania and New South Wales. Subsequently the deficiency was found in a wide range of pasture and crop plants. Crops with higher boron requirements such as lucerne, sunflowers, rapeseed, cauliflower and apples are most likely to respond to boron. Pine trees, which are commonly used in tree lots and as windb...

Soldier fly, Inopus rubriceps (Macquart), larvae suck nutrients from the roots of ryegrass, ‘reducing root growth, tiller and foliage production, and probably plant survival. Accurate placement of insecticide with the seed killed larvae, and en’hanced establsishment of the seedlings. The use of minimum cultivation, paraquat, and fertilizer sown with the seed, ‘all made larvae move on to the row...

Grazing management is a key factor in pasture-based dairy systems, which can be improved given advanced knowledge of the effects of pregrazing pasture mass (PM) on the performance of dairy cows. The aim of this study was to quantify the effects of PM on the pasture intake, milk production, milk composition, and grazing behavior of strip- or rotational-grazing dairy cows, based on a meta-analysi...

1. In endangered wooded pasture ecosystems established tree saplings are frequently found in spatial association with protective structures, suggesting nurse effects. This associational resistance is thought to be a driving force behind tree regeneration in wooded pastures. Experimental evidence for associational resistance is, however, scarce. We studied the effects of unpalatable plants on tr...

The possible effects of seed priming on mitigating the effects of drought stress on germination and early seedling growth of two rangeland plants were evaluated in a laboratory research during 2015-16 growing season. The research was conducted as a 2×3×3 factorial experiment based on completely randomized design with three replications. The first factor was plant type (Festuca ovina and Bromus ...

Warming due to global climate change is predicted to reach 2°C in tropical latitudes. There is an alarming paucity of information regarding the effects of air temperature on tropical agroecosystems, including foraging pastures. Here, we investigated the effects of a 2°C increase in air temperature over ambient for 30 days on an established tropical pasture (Ribeirão Preto, São Paulo, Brazil) do...

The objective of the study was to characterize annual ryegrass seed population dynamics, managed for natural re-sowing, in no til systems in rotation with soybean, in different chronosequences An area was cultivated for two years with soybean, left as fallow land for the next two years and then cultivated again with soybean for the next two years. The four chronosequences represented different ...

Nitrification, a key process in the global nitrogen cycle that generates nitrate through microbial activity, may enhance losses of fertilizer nitrogen by leaching and denitrification. Certain plants can suppress soil-nitrification by releasing inhibitors from roots, a phenomenon termed biological nitrification inhibition (BNI). Here, we report the discovery of an effective nitrification inhibit...

abstract in iran, border regions are considered as strategic and critical locations. potential, natural, and economic constraints as well as being away from the capital, and consequently from power and decision-making centers are some of the main features of these regions. in this regard, the establishment of border markets is one of the most recognized methods for the economic development of b...
