Forage quality is one of the most important factors that is necessary for proper nutritional management of livestock from rangelands. The most important quality factors of plants are crude protein, ADF, crude fiber, metabolic energy and digestible dry matter. The present study was conducted to evaluate the forage quality of high-yielding herbaceous species (Astragalus brevidens and Astragalus v...
Dry direct-seeded rice (dry-DSR) is an efficient, resource-saving and environmentally friendly cropping system. The employment of water-saving drought-resistant (WDR) for dry direct-seeding can better meet the needs dry-direct seeding systems. However, decline in seedling emergence rate poor growth are main bottlenecks under current production. Seed treatment a sustainable effective technique t...
agroforestry is one the aspects of sustainable agriculture in which multiple cropping of perennial trees in mixture with crops guarantees the environmental, economical and social sustainability in rural communities. high demands for forage in northern provinces of iran lead to agroforestry in citrus orchards as a potential mean for forage production through agroforestry systems. this research w...
Significant reduction of the breakdown threshold in a DC microdischarge via seeding metal nanoparticles has been demonstrated. Compared to standard Paschen curves in dry air, reductions in the breakdown voltage of 5% to 25% were obtained for PD values (the product of pressure and electrode gap distance) ranging from 20 to 40 Torr-cm by seeding aluminum and iron nanoparticles with mean sizes of ...
Dry direct-seeding of rice is rapidly increasing in China, but variable planting depth associated with machine sowing can lead to low seedling emergence rates. Phenotype analysis of 621 rice accessions showed that mesocotyl length (ML) was induced by deep soil covering and was important in deep-sowing tolerance in the field. Here, we performed and compared GWAS using three types of SNPs (non-sy...
The objective of the work was to provide a method to predict CO2 and NH3 yields during composting of the biodegradable fraction of municipal solid wastes (MSW). The compostable portion of MSW was simulated using three principal biodegradable components, namely mixed paper wastes, yard wastes and food wastes. Twelve laboratory runs were carried out at thermophilic temperatures based on the princ...
Elemental sulfur (ES) fertilizers have high S content but may not be effective in the year of application due to time required oxidize. Rapid oxidation possible if ES has a large surface area contact with soil. We evaluated efficacy Sulgro 70, micronized fertilizer that is sprayed onto soil surface, eight field trials southern and central Alberta over 2 yr period. Under dry conditions Alberta, ...
یکی از مهمترین علت های ایجاد کننده درد، اختلالات اسکلتی-عضلانی می باشد، که حدود یک سوم آنها دارای سندرم میوفاشیال همراه با نقاط ماشه ای می باشند. وجود نقطه ماشه ای در عضله تراپز فوقانی یکی از یافته های شایع در افراد مبتلا به اختلالات ناحیه گردن و پشت است. اخیرا استفاده از dry needling به عنوان یکی از روشهای جدید درمانی جهت درمان نقاط ماشه ای مطرح شده است. هدف از این مطالعه بررسی اثرات دو روش در...
