Zinc deficiency in crop plants has been recognized as a worldwide nutritional constraint. A greenhouse experiment was conducted with the objective of developing a screening technique to evaluate lowland rice genotypes for zinc use efficiency. Ten lowland (Oryza sativa L.) genotypes were tested at low (0 mg Zn kg) and high (10 mg Zn kg) zinc levels applied to an Inceptisol. Genotypes differed si...

grasspea (lathyrus sativus) is a protein-rich forage legume that contains a neurotoxin (beta-odap) that causes severe malformation of the body’s extremities when eaten in large quantities. various low-toxin lines of grasspea have been developed to reduce the toxin’s concentration in the grain, i.e. to below the 0.2% critical value, but there are indications that zinc (zn) can also reduce the to...

Seventy-six farmers' varieties of sorghum from Benin were distinguished by amplified fragment length polymorphism (AFLP) and clustered into 45 distinct genotypes. The genotype clusters were evaluated for their Fe, Zn, and phytate concentrations to assess the impact of genetic and environmental effects on the composition of the grains and to identify farmers' varieties with high potential Fe and...

A field experiment was carried out in the Light village of Netrokona Sadar during the period from December 2010 to March 2011 to study the performance of some wheat varieties in terms of nutrient contents and their uptake. The experiment comprised of five varieties of wheat viz. BARI Gam 25, Shatabdi, BARI Gam 26, Prodip and Bijoy. The experiment was laid out in a randomized complete block desi...

Background: Vitamin A (VA) and zinc deficiencies are prevalent. Maize is a common staple, and milling affects nutrient and nutrient-modifier profiles.Objective: We investigated the interaction of maize milling methods (i.e., whole grain compared with refined) in male Mongolian gerbils aged 29-35 d with conventionally bred provitamin A-biofortified (orange) or white maize on VA and zinc status.M...

Zinc (Zn) de®ciency is a critical nutritional problem for plants and humans in Turkey. About 14 Mha of cropped land in Turkey are known to be Zn de®cient, particularly cereal growing areas of Anatolia. In 1993, a joint research project was started in Turkey with the ®nancial support of the NATO-Science for Stability Programme to select and characterize cereal genotypes with high yield and/or hi...

This study was conducted to determine status of heavy metals in agricultural soils under different patterns of land use. A total of 38, 40 and 45 soil samples for bare vegetable field, greenhouse vegetable field, and grain crop field were respectively taken from surface layer (0-20 cm) from selected experimental areas away from suburbs of ten counties (or districts or cities) in four provinces ...
