This study wanted to clarify the impact of silicon (Si) fertilization on nutrient uptake, use efficiency, yield and quality rice detect rate mode application Si fertilizer in deficient soil. The field experiment was conducted with ten treatment combinationsof100% NPK,100% NPK + potassium silicate (PS)@ 0.25%,0.50% 1.0% Foliar spray (FS) at tillering stage,100% PS@ 0.25% ,0.50% 1.0%FS panicle in...
Axillary meristems (AMs) are secondary shoot meristems whose outgrowth determines plant architecture. In rice, AMs form tillers, and tillering mutants reveal an interplay between transcription factors and the phytohormones auxin and strigolactone as some factors that underpin this developmental process. Previous studies showed that knockdown of the transcription factor gene RFL reduced tillerin...
Heterosis is a common phenomenon in which the hybrids exhibit superior agronomic performance than either inbred parental lines. Although hybrid rice is one of the most successful apotheoses in crops utilizing heterosis, the molecular mechanisms underlying rice heterosis remain elusive. To gain a better understanding of the molecular mechanisms of rice heterosis, comparative leaf proteomic analy...
A greenhouse experiment was conducted to evaluate the effect of nitrogen (N) and salinity on dry matter yield, N uptake, nitrate (NO3-) concentration, agronomic efficiency (AE), physiologic efficiency (PE), apparent nitrogen recovery (ANR) and chlorophyll content of spinach shoots (cv. Viroflay), and also total N, NO3-N and electrical conductivity of post-harvest soil. The experiment was factor...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...
Extended Abstract Introduction and Objective: In order to investigate the effect of foliar application of main elements and micronutrients on morpho-physiological and yield traits of rice plants with the aim of increasing yield and reducing the use of chemical fertilizers, experiments in the cropping years 2015-2016 and 2016-2017 in the research farms of Nowshahr city (Mazandaran) was implemen...
Diagnosis of large discrete event systems leads to combinatorial explosion. We propose to solve this issue by ignoring some connections on the system and using a junction treebased approach. Removing connections reduces both the cost and the accuracy of the diagnosis. Therefore, we perform an off-line analysis to determine which connections can be safely ignored.
The effects of goitrogens on the thyroid gland have been much studied and calcium is considered as a goitrogen in some cases. Since the level of calcium is high in drinking water of some cities of Khozestan province, the effects of high calcium intake on the function of thyroid gland is investigated in this study. For this purpose the concentration of thyroid hormones is measured in rats. The s...
