BACKGROUND With the goal of preventing open neural tube defects (NTDs), recommendations for folic acid supplementation before conception were introduced in Canada in 1994, and by November 1998 Canadian grain products were being fortified with folic acid. We wished to determine whether the annual incidence of open NTDs in Nova Scotia, including those in stillbirths and terminated pregnancies, ch...

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...

This experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. The experiment was a factorial design with three replications. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate  biofrtilizers (Phosphate barvar2, Biozarr and Superplass) with control for them and yield components we...

genetic variation is necessary factor for continued breeding and increasing genetic gain from selection in crop plants. to evaluate genetic variation and genetic gain from selection in bread wheat, 45 genotypes consisting of 9 cultivars and their 36 crosses were grown in a randomized complete block design with three replications in research farm of isfahan university of technology. the phenotyp...

to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...

Rice grain yield and quality are two major foci of rice breeding. In this study, Chinese regional rice test data provide us the unique opportunity to analyze the relationship between yield and quality in rice, because China has an unusually wide range of rice cultivars. We analyzed the relationships between grain yield, yield components, and grain quality of 300 rice germplasms. Japonica was su...

Systematic experiments have been performed to investigate the rate sensitivity of deformation in fully dense nanocrystalline Ni using two different experimental techniques: depth-sensing indentation and tensile testing. Results from both types of tests reveal that the strain-rate sensitivity is a strong function of grain size. Specifically microcrystalline and ultra-fine crystalline pure Ni, wi...
