The purpose of this factorial field experiment was to investigate the influence farming systems (FS) and intercropping patterns (IPs) on physiological aspects safflower bitter vetch. Treatments included high low-input various IPs that exchanged vetch with row ratios 2:2, 2:3, 2:4, 2:5, while sole cropping (SS) (SB) were used as control. highest grain yield both plants obtained from input system...

I have measured acetylene diffusion through plant tissues including nodules from several species of legume-vetch, peas, soybeans, and Sesbania rostrata. The observed half-time for reequilibration of internal and external concentration is less than 1 minute for typical nodules. Inward diffusion of acetylene in air is rapid relative to the use of acetylene by nitrogenase so that diffusion of acet...

In south-western France, sunflowers are usually grown in short rotations and after a long fallow period during which soils left bare. This practice can favour diseases, caused by soilborne fungi, such as sunflower verticillium wilt (SVW), well nitrate leaching, both of decrease yields. Growing cover crops is an agroecological that could provide ecosystem services mitigate SVW. A Brassicaceae cr...

Two new species of Hyalella S.I. Smith, 1874 are described from state Jalisco, Mexico. marysolae sp. nov. can be identified by the presence small projections or carinae on pleonites 1−2, with first antenna being composed 12 articles and second 15 articles. The maxilla bearing 2−3 distal pappose setae, propodus in male gnathopod is hammer-shaped. Conversely, H. morronei nov., dorsal absent 10 14...

common vetch ( vicia sativa l.) an annual forage, belonging to the fabaceae family is one of the highly cultivated forage legumes in iran. drought stress is a serious adverse factor that limits plant growth and productivity, inducing a range of physiological as well as biochemical responses in plants. it may also lead to generation of oxygen activated species which in turn result in cell destru...

this study was conducted to investigate economic aspect and some soil properties in different crop rotations of wheat in dryland conditions in sararood - kermanshah during six years 2006-2012. the experiment carried out based on randomized complete block design (rcbd) with four replications in two neighbor sites. treatments were wheat-wheat, fallow - wheat, chickpea-wheat, vetch-wheat and saffl...

increases forage production and economic production in rainfed condition requires attention to agricultural issues such as determination of appropriate sowing depth. so in order to determine the effect of different sowing depths of vetch this experiment was conducted in agricultural research station of maragheh as strip plot based on randomized complete block design with three species of vetch ...
