Agronomic bio-fortification is one of the main approaches for mitigation of micronutrient shortage in human populations and endorses sustainable production of food and feed. Studies related to agronomic bio-fortification of crops are mainly focused on single or rarely two micronutrients application, and no attempt has made to study the combined effect of zinc (Zn), iron (Fe) and selenium (Se) on forage sorghum. Therefore, this research was accomplished to evaluate the effect of Zn, Fe and Se bio-fortification on diverse sorghum accessions. The field experiments were conducted in a randomised complete block design with a split-plot arrangement. The treatments comprised of Zn (10 mg/L as ZnSO<sub>4</sub>∙5H<sub>2</sub>O), Fe (7 mg/L as FeSO<sub>4</sub>∙7H<sub>2</sub>O), Se (3 mg/L as SeSO<sub>4</sub>) and CK (control) were applied to five sorghum accessions: G<sub>1</sub> (Y-16), G<sub>2</sub> (YSH-166), G<sub>3</sub> (YSH-134), G<sub>4</sub> (YSS-98) and G<sub>5</sub> (YSH-132). According to our results, the sorghum accession G<sub>5</sub> showed superiority over all other accessions and produced maximum values of all growth and quality traits except grains number per panicle and 1 000-grain weight. All applied micronutrients (Zn, Fe and Se) enhanced the growth, quality and uptake of nutrients in sorghum accessions. However, Se recorded the highest plant height, stem diameter, 1 000-grain weight and Zn produced the maximum protein, oil and starch contents. Conclusively, it can be concluded that G<sub>5</sub> with Se must be used to achieve the optimum values of agronomic traits, while G<sub>5</sub> with Zn found more effective to improve the quality traits of sorghum.
Camelina sativa (L.) Crantz is an emerging oil seed crop and research information on its response to different levels of phosphorous (P) fertilizer is lacking. The two years study was performed to investigate the response of C. sativa to various rates of P fertilizer. The experiments were laid out in Randomized Complete Block Design (RCBD) with factorial arrangement having four replications. The P was applied in soil at the rate of 0, 30, 40 and 60 kg ha-1 to two C. sativa accessions namely Canadian and Australian. Soil applied phosphorus rates had significant effects on the growth, yield and quality of C. sativa and two accessions were varied to each other. Australian accession performed better in terms of quality traits and Canadian was superior in terms of seed yield. An increase in P rate improved growth, yield and quality and 60 kg P ha-1 resulted in maximal crop growth rate (6.79), seed yield (1239 kg ha-1), total P uptake (0.67%) and oil contents (39.8%). The regression model estimated that each increment in P rate increased the seed yield by 11.5 and 11.2 kg ha-1 in Canadian and Australian accessions, respectively. Conclusively, increases in P rates (0 to 60 kg ha-1) impart a positive impact on C. sativa accessions and 60 kg P ha-1 was most effective to achieve optimum yield and profitability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
