Zinc is an essential micro-nutrients for humans and plants. Zinc on humans is obtained from food, especially rice. This research studied the effect of zinc sulfate heptahydrate spraying application, the effect of zinc sulphate heptahydrate enriched urea application, and the interaction of both, on yield and rice zinc grain concentration in Ciherang varieties. The research was carried out by RCBD. The first factor was without spraying zinc sulfate, spraying 75 g ha-1 zinc sulfate heptahydrate and spraying 150 g ha-1 zinc sulfate heptahydrate. The second factor was without zinc sulfate enriched urea, urea enriched by 7.5 kg ha-1 zinc sulfate heptahydrate, and urea enriched by 15 kg ha-1 zinc sulfate heptahydrate. The parameters observed were grain yield, grain zinc concentration, and rice plant growth. Data were analyzed by analysis of variance at 5% and DMRT test at 5%. The results indicated that spraying 75 g ha-1 zinc sulfate heptahydrate increased yield of rice up to 13%, urea enriched by 7.5 kg ha-1 zinc sulfate heptahydrate increased grain yield zinc concentration up to 33%, Combination of spraying  75 g ha-1 zinc sulfate heptahydrate and urea enriched by 7.5 kg ha-1 zinc sulfate heptahydrate can’t increased the yield and zinc grain concentration.<br /><br />Keywords: rice, urea, zinc, zinc sulfate heptahydrate<br /><br />

AbstractFoliar application of micronutrient is a rapid and promising strategy to enhance the concentration and bioavailability of micronutrients in wheat grain. To explore the effects of foliar application of micronutrients on the concentration and bioavailability of zinc and iron in grain in wheat cultivars and landraces, field experiments were carried out using 65 wheat cultivars and 28 landraces to assess the effects of foliar application of zinc (iron) on phytic acid concentrations, zinc (iron) concentrations and their molar ratios. The results indicated that mean grain zinc concentration of landraces (44.83 mg kg−1) was 11.13% greater than that of cultivars (40.34 mg kg−1) on average across seasons, while grain iron concentration did not differ significantly between landraces (41.00 mg kg−1) and cultivars (39.43 mg kg−1). Foliar zinc application significantly improved the concentration and bioavailability of zinc in grains in both cultivars and landraces, while landraces had almost two-fold more increase in grain zinc and also greater improvement in zinc bioavailability compared to cultivars. While foliar iron application did not significantly affect iron concentration and bioavailability in grains in either cultivars or landraces. Our study showed that, with foliar application of zinc but not iron, wheat landraces had better performance than cultivars in terms of the increases in both concentration and bioavailability of micronutrient in grains.

Rice (Oryza sativa L.) is the source of energy and nutrition for more than half of the world’s population hence it is a crop of global significance. Breeding of mineral dense rice varieties is the main target of biofortification strategy to address micronutrient malnutrition globally. Landraces and local genotypes are proven sources of novel alleles and are a promising donor for high grain mineral. A parental polymorphism survey is a prerequisite of any QTL mapping experiment. Present study consisting of SSR markers based parental polymorphism survey at IRRI South Asia Hub ICRISAT, Hyderabad. Parents of mapping population viz Rajendrakasturi (short grain aromatic rice variety with low grain zinc content) and URG-30 (a local genotype from Eastern Uttar Pradesh with high grain zinc content) were screened with 1013 microsatellite markers covering the entire length of all 12 chromosomes to study allelic variation at genome-wide SSR loci. The geographical diverse origin of parents is reflected in genotypic variations in terms of polymorphism. Out of 1013 whole genome wide SSR markers screened, 294 were found to be polymorphic which resulted in 29.02% polymorphism between the two parents. The highest polymorphism was observed with chromosome 4 (40.96%) whereas the lowest polymorphism was observed in chromosome 9 (16%). Based on the outcomes of the present study, a set of genome-wide polymorphic SSRs will be selected for genotyping of mapping population, preparation of linkage map and QTL analysis for high grain zinc content, iron content, grain quality and yield traits.
