Agriculture of the inland arid region in Xinjiang depends on irrigation, which forms oasis of Northwest China. The production and water use of wheat, a dominant crop there, is significantly affected by undergoing climate variability and change. The objective of this study is to quantify inter-annual variability of wheat yield and water use from 1955 to 2006. The farming systems model APSIM (Agr...

The belt uniform (BU) sowing pattern can improve the yield of winter wheat, but whether and how BU increase under different densities is unknown. field study was conducted in Guiyang (Guizhou province) during growing season 2017–2018, 2018–2019, 2019–2020. Four wheat cultivars were used experiments to investigate changes dry matter accumulation partition, components at maturity five (75, 150, 2...

In order to evaluate the effect of biofertilizers (Rhizobium and mycorrhiza) on yield and qualitative characteristics of Pinto bean under deficit irrigation, an experiment was conducted as split plot based on a randomized complete block design with three replications in 2017. Experimental treatments included irrigation regime with two levels (normal and deficit irrigation) as main plots and bio...

The article discusses the impact of machine-tractor unit (MTU) undercarriages during soil cultivation and agricultural crops. With a movement row-crop units across field, MTU propellers repeatedly compact soil. This negatively affects production seedlings, growth development plants, yield In this regard, these studies are purposed at determining compaction effects on conducting an agroecologica...
