The effects of cropping systems (fallow, rotation with sorghum-sudangrass hybrid [Sorghum bicolor x S. sudanense], and continuous soybean [Glycine max]), nematicide (aldicarb) treatment, and soybean cultivar on yield and nematode population densities were studied in a field infested with a mixture of Meloidogyne spp. and Heterodera glycines. Soybean following sorghum-sudangrass yielded 111 kg/h...

Rainfed wheat (Triticum aestivum L.) is planted each year on 1.5 million ha in the low-precipitation region (150 to 300 mm) of north-central Oregon and south-central Washington. Precipitation occurs mostly (75%) from late autumn (October) to early spring (April) and the amount is highly variable from year to year. Winters are cold and intervals of frozen soil are common. Warm to hot days and co...

In the conditions of a small-scale experiment on natural infectious background (Belgorod, Russia), threefold excess CFU values rhizosphere Melilotus officinalis was revealed in comparison with fallow soil, but abundance typical species and control 63% 77%, respectively. The Jacquard coefficient proved high similarity mycocomplexes M. (33%). core microcomplex sweet clover is Trichoderma lignorum...

The current paper has presented the results of study conducted in southern part Rostov region by Agricultural Research Center “Donskoy” 2019–2021. purpose work was to identify how grain productivity and its qualitative indicators winter bread wheat variety ‘Yubiley Dona’ are formed under influ­ence various sowing dates after forecrops estimate economic efficiency these elements cultivation tech...

African mahoganies of the genus Entandrophragma are among the most valuable and important timber species harvested in Central Africa, representing more than 70% of total export volume from many areas. In spite of the importance of these species, relatively little is known about their regeneration ecology and little effort has gone into understanding the reasons for the consistently reported reg...

The experiment was conducted at Dobila, Tarash of Shirajgonj in chalanbeel during the Rabi seasons 2018-2019 and 2019-2020 to improve existing cropping pattern, increase intensity, yields economic return through incorporating modern crop varieties improved management practices. treatments were i) Mustard (var. BARISarisha-14)-Boro-Fallow ii) BARI Sarisha-15)- Boro-Fallow iii) Tori-7)-Boro-Fallo...

for increasing cropping intensity, improving soil quality, and controlling erosion in the conventional fallow areas For most of a century, the wide spread practice of growing only (Papendick, 1998). However, research with spring crops, one crop every other year in a tillage-based wheat (Triticum aestivum L.)–fallow rotation has degraded soils and contributed to environmenand in particular with ...

Background: The combined use of green manure and legumes in binary legume-crop mixtures allows farmers to efficiently produce a sufficient amount human food animal feed. purpose this study is examine how biologization the different soil cultivation techniques legume cropping affects chernozem fertility productivity rotation crops. Methods: studies were conducted between 2017 2019 3 crop rotatio...
