Introduction. Reducing the distance of throwing soil into zone around bushes and maintaining a leveled surface between rows berry crops are urgent scientific problems. Aim Article. To identify basic parameters for interaction spherical disk with waterlogged on this basis to develop technical solution reducing away in space crops. Materials Methods. The object research is an orchard disc harrow ...

In the Siberian Arctic, worldwide largest forest mortality was caused by chronical (since 1940s) influence of SO2 emissions on larch-dominant communities. We hypothesized that warming might mitigate increasing trees’ vigor and growth. studied trees (larch, Larix sibirica; spruce, Picea obovate; birch, Betula pendula) bushes (willow, Salix sp., alder, Duschekia fruticosa) growth dependence SO2, ...

Abstract The European Turtle Dove (turtle dove) is globally threatened after undergoing a sustained and generalised decline across its breeding range, with habitat loss suggested as the main driver. Here, we reviewed scientific literature on associations in relation to distribution, numbers, nesting substrates, food foraging habitats, identify optimal management measures. Large-scale distributi...

In this paper, we study the almost sure scattering for Klein–Gordon equations with Sobolev critical power. We obtain random initial data in Hs×Hs−1,3d−14(d−1)<s<1 4≤d≤6. use induction on scales and bushes argument Bringmann (2018) where model equation is wave equation. For d=5,6, mass term of to control increment energy process scales.

this study was aimed to the examination of the effect of tillage row spacing and bush spacing on the performance and components of phaseou vulgaris var. (line: cos16). the investigation was conducted as cut terraces and in terms of complete random blocks in three replicates at brujerd agricultural research and natural resources in the agricultural year 2009-2010. here, the main terraces with th...

cumin is an annual plant suitable for dry and semi-dry regions. it is harvested at two stages to prevent seed shedding. first, the cumin bushes are harvested by hand or using a scythe. after drying, the cumin bushes are beaten with a stick or trampled using animals or a small tractor. this harvesting method is time consuming, requires intensive labor and is an incomplete threshing process resul...
