Potassium is one of nutritional element that has an important effect on the quantity and quality of rice plant. Knowledge about the K critical level and plant response to different application rate of K, can effectively help with the proper use of this element. Therefore, in this study potassium (K) critical level for rice (Khazar variety) and prediction equation for grain yield were determined...
results no significant changes were observed in serum potassium, phosphorus and calcium levels at the end of the passive exercise program compared to the baseline. however, phosphorus levels were significantly decreased in the active exercise program (p < 0.05). moreover, the mean diastolic blood pressure was significantly decreased after the passive exercise (p = 0.039). passive exercise did n...
Tree uprooting creates multiple microsites that can be effective on soil heterogeneity. In order to investigate the soil features in pit and mound location, twenty hectare areas of Tarbiat Modares University Experimental Forest Station studied that is located in Mazandaran province, in the north of Iran. Numbers of thirty four uprooted trees were found in study areas. Five microsites were con...
The development of common bean cultivars with high technological quality that are biofortified with minerals, is required to meet the demand for food with health benefits. The objectives of this study were to evaluate whether common bean genotypes differ in terms of technological and mineral biofortification traits, to study the correlations between these characters, to analyze the genetic diss...
Relationship of is one of the most useful interactions in terrestrial ecosystems that its positive effects on growth, physiology and ecology of different plants has been documented. This study investigated the relationship between important physicochemical characteristics of soils such as pH, electrical conductivity (EC), soil texture, organic carbon percentage, soil potassium percentage and t...

This paper proposed a simulation model of soybean growth which is effected by major nutrient factors, nitrogen, phosphorus and potassium. A feedforward neural network is used as a basis of the modelling. The combination of different percentage of nitrogen, phosphorus, potassium, time steps and the collected height data of the soybean are used as inputs. The model can predict the height at desig...
In order to investigate the effects of phosphorous and potassium fertilizers on some important morphological traits, agronomic characteristics and yield of red bean cultivars, an experiment was conducted at Agricultural Research Farm of Islamic Azad University, Arak, in the summer of 2013-2014 and in two consecutive years. This experiment was conducted as split plot based on randomized complete...
