چکیده

The article is devoted to determining the optimal sowing time for soybeans with stable warming of soil, considers processing a stratifier PRSM-5 and chisel against background pre-sowing rolling. Using soil-cultivating units three types, an analysis was made effectiveness various methods basic cultivation agricultural practices. timing soybean determined heating soil 8–10 o С when treated up 10–12 during obtained results research showed that density depends primarily on method cultivation. indicators as whole after treatment it somewhat less averaged 1.04 g/cm3 , – 1.09 . structural composition best structure noted due removal most agronomically valuable lumps from lower layers surface, here coefficient high reached 2.36, 2.08. An reserves productive moisture at end growing season they were used more rationally, significantly decreased in phase full ripeness amounted 57 mm, 69 mm. experimental data indicate under dry weather conditions, yield formed second date, loosening - first Key words: soybean, tillage, PRSM-5, density, structure, yield.

Different sowing dates affected cotton yield and yield components

This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

Influence of herbicides on yield stability of winter wheat cultivars under different sowing rates

Yield variability of selected winter wheat cultivars under different sowing rate and selected application, was investigated during 2006-2008, in the Lower Silesia region (South-West Poland). Experiments with two varieties, two levels of sowing rate and seven herbicides, including untreated object were set up on the same field, using split-plot method. For evaluation of yield stability Kang'...

Developing scenarios to assess sunflower and soybean yield under different sowing dates and water regimes in the Bekaa valley (Lebanon): Simulations with Aquacrop

In a semi-arid environment, the main challenge for crop production is water limitation in space and in time. Considered as appropriate tools, models are used to evaluate the effects of water deficit on crop productivity for better irrigation planning and sustainable yield. The AquaCrop model was tested using data collected during a 4-year experiment on soybean (Glycine max L. Merril) and s...
