Sorghum and pearl millet are two important dry land crops that provide grain and fodder. India is the largest pearl millet producer and second largest producer of sorghum in the world. The productivity of these crops has been low due to various reasons such as unavailability of quality inputs to the farmers, lack of access to improved technologies for crop production, unavailability of credit o...
Rapeseed needs a sufficient amount of nitrogen for optimal seed yield, but the efficiency of this plant in using nitrogenous (N) fertilizers is low, which causes an increase in N consumption in the cultivation of this plant. The need to maintain a high grain yield necessitates the use of a suitable timely program and manage the consumption of N fertilizers. Thus, a field experiment was conducte...
To determine the relationships between agronomic and physiological characteristics of soybean, 30 soybean genotypes in factorial experiment based on a randomized complete block design were planted in Sari of Agricultural Sciences and Natural Resources University (SANRU). Correlation coefficients between traits showed positive and significant correlation between the considered traits and grain y...
in order to study the effects of different nutrition systems (organic, chemical and integrated) and biofertilizer (pgpr) on phenology period, grain yield and its component in sunflower (helianthus annuus l.) an experiment was conducted using alestar cultivar at the research farm of college of agriculture, tarbiat modares university in 2007. five levels of nutrition systems including f1 (100% or...
The microstructure, phase composition, and microhardness of both gas-atomized and mechanically milled powders of the Al7075 + 1 wt % Zr alloy were investigated. The gas-atomized powder exhibited a cellular microstructure (grain size of a few µm) with layers of intermetallic phases along the cell boundaries. Mechanical milling (400 revolutions per minute (RPM)/8 h) resulted in a grain size reduc...
Nanotendril "fuzz" will grow under He bombardment under tokamak-relevant conditions on tungsten plasma-facing materials in a magnetic fusion energy device. We have grown tungsten nanotendrils at low (50 eV) and high (12 keV) He bombardment energy, in the range 900-1000 °C, and characterized them using electron microscopy. Low energy tendrils are finer (~22 nm diameter) than high-energy tendrils...
A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
In order to assessment of grain yield and some of morphological characters in safflower genotypes under irrigated and rainfed conditions fifteen spring safflower genotypes were studied using two separate experiments based on randomized complete block design with three replications in 2010-2011 growing season at Miandoab Research Station, Iran. Analysis of variance for each conditions revealed s...
Introduction: Among circumstellar grains produced around O-rich evolved stars, silicate grains are the most abundant [1]. Until recently, the identification of presolar silicate grains in extraterrestrial materials proved difficult due in part to their destruction by parent body processes, requiring analysis of very primitive samples, and to the experimental challenge presented by their submicr...
