In order to study the genetic and environmental variability of morphological and phenological characteristics and also to gain a better understanding of the morphological basis of yield variation in soybean, an experiment was conducted at Research Farm, College of Agric., Isfahan University of Technology, in 1996. The experiment was arranged in three augmented designs with 285 lines and 5 contr...
In the case of delayed planting of cotton, using cotton plantlets may lead to a better acquisition of light and water throughout the plant growth and hence an enhanced plant growth and yield. Therefore, in order to evaluate the effect of transplanting method on cotton quantitative and qualitative traits, a 2-year field research was carried out using a split plot design experiment with different...
Rotating soybean (Glycine max cv. Kirby) with peanut (Arachis hypogaea cv. Florunner) for managing Meloidogyne arenaria race 1 was studied for 3 years (1985-87) in a field near Headland, Alabama. Each year soybean plots had lower soil numbers of M. arenaria second-stage juveniles (J2) at peanut harvest than did plots in peanut monocnlture. Peanut following either 1 or 2 years of soybean resulte...
A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...
Southwest of China is one of the major soybean (Glycine max L.) production regions in China with low availability of soil phosphorus (P). Whereas little information is available on P-efficient soybean genotypes in this region, even though using P-efficient soybean genotypes is a sustainable P management strategy for enhancing yield and P use efficiency. To assess the genetic variation on P use ...
The effect of3levels of methionine (NRC recommended, 5 percent more than NRC recommended and 10 percent more than NRC recommended) and 2 levels of fat (0 and 5 percent) on some economical traits (performance and carcass) of broilers using a 2x3 factorial experiment with completely randomized design based on two rearing stages, starter (0-3 wk) and grower (4-6 wk) was studied. ANOVA of the effec...
The condensation of acetone using anhydrous hydrogen chloride results after three weeks at room temperature, in a 1 5 % yield of phorone (4) and a 7 5 % yield of mesityl oxide (5). In the presence of one weight percent of the Lewis acid, aluminium chloride, the yield of 4 is increased to 3 9 % . An increase in the amount of the Lewis acid, aluminium chloride, to ten weight percent results in a ...
Contrast degradation is a critical problem in ultrasound plane wave imaging (PWI) resulting from signals leakage from the sidelobes. An ideal sidelobe reduction method may enhance the contrast without remarkably increasing computational load. To this end, we introduce a new singular value decomposition (SVD) sidelobe reduction beamformer for coherent plane wave compounding (CPWC) based on a pre...
crop rotation is one of the essential practices in sustainable agricultural systems, be-cause of its effects on soil fertility and other benefits including a reduction in weed compe-tition. a field experiment was conducted at chaparsar rice research station, tonekabon, iran, from 2002 to 2003 to assess the influence of crop rotation, time of planting, and till-age depth on rice (oryza sativa l....
in order to investigate antioxidant and antimicrobial effects of pomegranate peel powder (ppp), this research was conducted as completely randomized design arranged in a 2 × 2 factorial experiment using pomegranate peel powder (0 and 2 percent) and soybean oil (so, zero and six percent in growing period; zero and eight percent in finishing period). one hundred and sixty 11-day-old ross 308 broi...
