Orobanche cumama wallr. is the sunflower root parasitic weed with special life stage in which seed germination and parasitism take place soil. In practice, applying microbial agents trapping crop rotation are utilized separately, or just one of them selected to control O. cumana. The development industry severely constrained on farmland, where there high density cumana’s banks. this study, two ...

The wild sunflower, an invasive alien species, is known to affect the performance of field crops. A experiment was conducted estimate effects different levels sunflower and common bean densities on yield components grain yield, as well quantify loss due their competition at varying densities. laid out in a randomized complete block design factorial arrangement with four replications. Hence, com...

Living roots and their rhizodeposits can stimulate microbial activity and soil organic matter (SOM) decomposition up to several folds. This so-called rhizosphere priming effect (RPE) varies widely among plant species possibly due to species-specific differences in the quality and quantity of rhizodeposits and other root functions. However, whether the RPE is influenced by plant inter-species in...

Four sunflower accessions were compared with a susceptible check, hybrid '894', in the greenhouse to determine their resistance to the banded sunflower moth, Cochylis hospes Walsingham, and their interaction with Bacillus thuringiensis Berliner variety kurstaki. Antibiosis, expressed as lower larval weight, was detected in all of the accessions. In addition to being antibiotic, sunflower access...

Sunflower (Helianthus annuus L.), belonging to the family „Asteraceae‟ is a diploid species (2n = 2x = 34). Sunflower is an important oilseed crop and is the preferred source of oil for domestic consumption and cooking worldwide (Hu et al., 2010). In the oilseed scenario, sunflower competes with other three major oilseeds, i.e. soyabean, groundnut and rapeseed mustard at global level. Sunflower...

Due to the pollutant regulations of Directive (EU) 2015/2193, need reduce emissions compounds such as NOx is a great importance for industrial boilers. This study was performed determine effect primary measures in reducing said pollutants by mixing or secondary air with FGR and supplying mixture combustion. The studies were conducted on low-scale biomass grate-firing furnace boiler stand 25 kW....

The effect of long term conservation tillage (CT) application on soil organic carbon (SOC) concentration, and on stratification ratios (SR) of SOC, soluble organic carbon (SOCs), microbial biomass carbon (MBC) and protease activity (PA) has been studied. The SR was established dividing values of these variables at 0-5 cm depth by values at 10-25 cm depth. The results were compared with those ob...
