Potassium is the most abundant nutrition element in the surface soil but most of the potassium is unavailable to the plants. The present study was conducted with the aim of isolation of potassium solubilizing bacteria from rhizosphere soil and evaluation of quantitative ability of released potassium from different sources of silicate by strains. For this propose, laboratory and greenhouse evalu...
Soilless culture (hydroponic) and timely supply of plants’ essential nutrients will increase their quantitative and qualitative performance. To assess the impact of N, K and Mg on yield and fruit quality of strawberry (Fragaria×ananasa cv. Sun Rise) an experiment was performed which included control treatment (no fertilizer application), two levels of urea (100 and 200 mg/L per pot), two levels...
Diatoms of the iron-replete continental margins and North Atlantic are key exporters of organic carbon. In contrast, diatoms of the iron-limited Antarctic Circumpolar Current sequester silicon, but comparatively little carbon, in the underlying deep ocean and sediments. Because the Southern Ocean is the major hub of oceanic nutrient distribution, selective silicon sequestration there limits dia...
Rice is a rich accumulator of silicon and its supply essential for the growth economic yield rice. Hence, field experiment was conducted in sandy clay loam soil belonging to Padugai series (Typic ustifluvent) at farmers holding Kuttalam block, Mayiladuthurai district, Tamil Nadu assess role improving agronomic characters rice ADT 43, Oryza sativa. The treatments included T1 - Recommended dose f...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
The structure of weeksite, K1.26Ba0.25Ca0.12[(UO2)2(Si5O13)]H2O, orthorhombic, a 14.209(2), b 14.248(2), c 35.869(4) Å, V 7262(2) Å3, space group Cmmb, has been solved by direct methods using data collected with MoK X-radiation and a CCDbased detector and refined by full-matrix least-squares techniques, on the basis of F2 for all unique reflections, to an agreement factor (R1) of 7.0% and a goo...
Photosystem II is extremely susceptible to environmental alterations, particularly high temperatures. The maintenance of an efficient photosynthetic system under stress conditions one the main issues for plants attain their required energy. Nowadays, searching alleviators goal maintaining productivity and, thereby, crop yield global climate change. Potassium silicate (K2SiO3, 1.5 mM) and silico...
To investigate the effects of silicon on the growth characteristics and the reduction of the powdery mildew damage to Zinnia (Zinnia elegans Jacq. ʻMagellanʼ), an experiment was carried out as a factorial experiment in the form of a randomized complete block design with two factors including eight treatments and three replications. The first factor included silicon concentrations at four levels...
abstract in order to study the effects of salinity and silicon application on biomass of leaves and root of purslane (portulaca oleracea l.), a greenhouse experiment was conducted at research greenhouse of ferdowsi university of mashhad using completely randomized desgin with three replications. employed two factors consisted of three levels of salinity using nacl (0.6, 11, 22 ds/m) and two lev...
In a field experiment, the effects of foliar application of silicon (sodium silicate 6mM) on yield and yield components of wheat cultivars (Shiraz, Marvdasht, Sirvan and Chamran) and also canopy temperature depression (CTD) under water stress conditions (F.C, 60 and 40% F.C.) were investigated during 2012- 2013 growing season using a split split plot as randomized complete block design with thr...
