Orobanche spp. (broomrapes) are holoparasites lacking in chlorophyll and totally dependent on their host for their supply of nutrients. O. crenata is a severe constraint to legumes cultivation and breeding for resistance remains as one of the best available methods of control. However, little is known about the basis of host resistance to broomrapes. It is a multicomponent event, and resistance...
Recent field studies in rice paddy fields in Japan and China have shown that N2O is emitted to the atmosphere not only after the application of nitrogen fertilisers under flooded conditions but also in a period from the final drainage to submergence in the following rice-growing season through nitrification or denitrification. Those results clearly indicate that CH4 and N2O emissions in rice pa...
Integrating cover crops (CC) in rotations provides multiple ecological services, but it must be ensured that management does not increase pre-emptive competition with the subsequent crop. This experiment was conducted to study the effect of kill date on: (i) CC growth and N content; (ii) the chemical composition of residues; (iii) soil inorganic N and potentially mineralizable N; and (iv) soil ...
Legume–grass mixture can greatly improve soil fertility to support the sustainable productivity. Root litter is an important source of organic matter, but its link with nutritional status in forage mixtures not clear. This study was aimed uncover whether relationship carbon (C) and nutrients between root would change mixing ratio. Changes C, nitrogen (N), phosphorus (P) were studied a 2-year ex...
Weeds not only cause yield and quality losses in cultivated plants but also hinder harvesting. To effectively reduce these negative effects, it's crucial to identify the weed species choose most appropriate control method. Conducting regular surveys areas where crops are grown is essential for this purpose. This study was carried out determine types, densities, frequency of occurrence barley, w...
The ongoing climate change, coupled with the transformations of cultivation practices and land use in sole crop production, may cause a significant decline sunflower yield stability. Considering that is third oilseed world market, 45 million tons grain per year, it takes fourth position vegetable oil implementation sustainable growing technology production necessity. above, goal research was to...
Cover crops (CC) have great potential to enhance the sustainability of agroecosystems. However, wide range possible rotations CC and cash (CaC) means that important knowledge gaps persist on how affects CaC. We investigated legacy effects five common (three monocultures: vetch, melilotus, barley, two mixtures: barley-vetch barley-melilotus) most CaC, maize wheat. A microcosm, semi-controlled ex...
Objective: To study plants purification capability of Cu on two cultivars of vetch plant (Vigna Radiata) in contaminated soils and their effects on morphological characteristics. Methods: we conducted a completely randomized trial as factorial. Different concentrations of Cu (0, 150, 300, and 400 mg/ Kg of dried soil) were used. After four weeks growth on contaminated soil, parameters such as...
Background and Objectives: Quality evaluation of the food proteins is important due to their biological and economical aspects. Among existing methods, True Protein Digestibility (TPD), Apparent Digestibility (AD), Net Protein Ratio (NPR), Protein Efficiency Ratio (PER) and Food Efficiency Ratio (FER) are suggested for evaluation of proteins quality. The present study was conducted to biologi...
