Information about soil moisture in the root layer is very important evaluating water availability for plants, erosion rates and various other hydrological characteristics. Previous research has found a technology measuring dielectric properties as estimator that can be carried out quickly field. The purpose of this study was to apply dielectricity estimating characteristics situ field at North ...

Opuntia spp. plants occupy an important socioeconomic role in arid and semiarid zones where water is scarce. Irrigation increases the productivity of these plants; however, its effect on yield, composition, physicochemical properties mucilage unknown. Three irrigation regimens were tested: non-irrigated (rainwater), supplemental (irrigation between field capacity (0.28 m3 m−3) permanent wilting...

The article presents the concept of an electromagnetic circuit generator with permanent magnets mounted on the surface rotor core designed for single phase work. Computation field-circuit model was shown. The spectrum of time course of voltages in the idle work was presented. The cross section with graphically presentation of magnetic induction in particular parts of electromagnetic circuits wa...

There is considerable disagreement as to whether or not water is equally available to plants in drying soil over the entire range from field capacity to wilting percentage. Some workers have repeatedly stated that water is equally available over this range (5, 18, 23, 24) while considerable data have accumulated which indicate that physiological processes in plants are altered as a result of de...

this study is trying to exploitations view point and permanent management problems of rangeland to evaluate in ranches damavand summer rangeland in amol county. statistical society are utilizations 15 ranch that with three methods, collective property, private property and council property from rangeland utilization and randomly from among their number 88 was selected. the research tool was a q...

Recent advances in soybean breeding have resulted in genotypes that express the slow-wilting phenotype (trait) under drought stress conditions. The physiological mechanisms of this trait remain unknown due to the complexity of trait × environment interactions. The objective of this research was to investigate nitrogen metabolism and leaf and seed nutrients composition of the slow-wilting soybea...

Soil hydraulic properties are an important factor to optimize and adapt water management for a given crop. Pedotransfer functions (PTFs) present solution predict soil variables such as properties, using fundamental properties. In this research, we compared two sources of information: iSDAsoil data field data, in four regions Morocco. We then used evaluate published developed new PTFs informatio...

Senescence of carnation flowers is characterized by autocatalytic ethylene production from petals and subsequent wilting of the petals. Recent studies on the regulation of ethylene production and wilting in senescing carnation petals revealed that (1) petal senescence is triggered by ethylene evolved from the gynoecium during natural senescence, (2) ethylene production in the gynoecium is induc...

There are some plants can replaced grass among cover plants. Cover plants are obvious solution of problem in these places that the most important plant is Frankinia and Lisimakia etc. The aim of this study is to use organic wastes, biological fertilizers and moisture super absorbents in the growth media of Frankinia to increase water holding capacity, delay in permane...
