Crystallization of Aluminum fluoride at atmospheric pressure has been considered. Structure, size and shape of crystals formed during the crystallization process have been investigated. By applying the direct analysis method for the existed aluminum in solution, the aluminum fluoride nucleation process has been detected as a concentration valley at the outset of crystallization process. The...
This research was carried out to determine nutritive value of Medicago polymorpha and Malva parviflora in various growth stages. The study was conducted at three rangelands during December 2013 to May 2014. The samples of plants were randomly taken in three stages including vegetative growth, flowering and maturity (seed production). Samples of each stage and place were analyzed for DM, CP, EE,...
In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different s...
Introduction: Assessment of national children growth has shown children‘s growth failure in a large percentage of them in Iran. Growth failure is easily diagnosed by growth monitoring card .On the other hand, mothers’ Knowledge of Nutritional development stages can help them to modify their practice in this field .In this case, conducting educational and interventional programs play a key role ...
In Guilan province, Sefidrud River, as the main source of irrigating rice in Guilan province, has been subjected to increasing salinity and a decreasing discharge because of decreasing in the volume of sefidrud dam, diverting water upstream and entering different sewages into the river. This research tries to determine optimum irrigation depth and intermittent periods in proportion to salinity ...
the objective of deficit irrigation is to increase water use efficiency by reducing of water quantity or wave off further irrigations that have not necessary. cotton plant is sensitive to irrigation timing and quantity through different growth stages. the field trail was conducted at hashemabad cotton research station (gorgan) to determine water consumption and cotton sensitivity to deficit irr...
Parameters that show a significant genotypic variation at early growth stages and are associated with salt tolerance at later stages may be used as rapid and economic screening criteria in breeding programs. The objective of this study was to test growth parameters at early growth stages for evaluating the salt tolerance of wheat genotypes. Ten wheat genotypes that differ from their salt tolera...
A standard description of growth stages for crops/plants is necessary not only for determining and improving cultural practices, but also to facilitate enhanced communication among producers, researchers, and educators. It also could help in unifying experimental results. Many different descriptions of growth stages are currently available for many crops, but there are no codes for sesame (Sesa...
