1. Khan, Habib Ur Rahman. Responses of chickpea (Cicer arietinum L.) to zinc supply and water deficits / by Habib Ur Rahman Khan.

Degree: 1998, University of Adelaide

Widespread deficiencies of mineral nutrients in soils along with limited moisture supply are considered major environmental stresses leading to yield losses in chickpea. This study was conducted to determine the zinc requirement of chickpea and the effect on plant water relations. Critical zinc concentration was estimated. It was found that high and low moisture regimes had no effect on critical zinc concentration and that the value remained almost the same in all chickpea genotypes. Sensitivity of 28 chickpea genotypes were evaluated at two zinc levels. Field studies on zinc fertilization in both Australia and Pakistan showed that the application of zinc increased grain yield in all chickpea genotypes. It was found that plants grown under zinc deficiency could not exploit available soil moisture and water use and water use efficiency was reduced, and concluded that high zinc availability may enhance the ability of plants to endure periods of drought by promoting osmotic adjustment. Advisors/Committee Members: Dept. of Plant Science (school).

2. Regmi, Basu Dev. Dynamics of zinc accumulation in wheat grains grown in biological and conventional farming systems.

Degree: PhD, 2012, University of Western Australia

[Truncated abstract] In the past, emphasis was placed on increasing grain production to feed the growing world population. The use of synthetic fertilizers, pesticides, mechanization and highyielding genotypes increased crop production and productivity after the Green Revolution. However, such practice resulted in low mineral content in edible crop parts. Among the minerals, zinc (Zn) is one of the most limiting in wheat grain. Also, more than 50 % of the world’s wheat growing areas are low in plant-available Zn, making Zn deficiency the most widespread micronutrient deficiency in crop production. Further, low plant available Zn in soils and drought resulted poor grain quality and quantity of wheat. Zinc plays a crucial role in plant metabolic and physiological processes, with low Zn not only reducing crop production but also decreasing the nutritional quality of edible plant parts. In addition, phytate in grain of cereals inhibits Zn absorption in human body. Therefore, increasing grain Zn density as well as lowering phytate concentration in wheat grain is important for increasing the bioavailability of Zn for improved human nutrition. This research provides detail information on distribution of Zn fractions in soils from biological and conventional farming systems, the role of soils in grain Zn concentration, the effects of Zn and phosphorus (P) nutrition on grain phytate and Zn concentrations, the relationship between nitrogen (N) fertilization and grain Zn concentration, and the effect of Zn nutrition on terminal drought tolerance in wheat. A sequential extraction method was used to fractionate soil Zn into water-soluble, exchangeable, specifically-adsorbed, acid-soluble, manganese-oxide-occluded, organic matter-occluded, amorphous iron (Fe)-oxide-bound, crystalline Fe-oxide-bound, and residual forms in soils from biological and conventional farming systems in Dalwallinu and Merredin, Western Australia.

An incubation study was conducted to investigate the dynamics of Zn fractions in these soils after application of two Zn fertilizers (ZnSO4 and ZnEDTA). All follow-up experiments were performed using wheat genotypes differing in tolerance to Zn deficiency (=Zn efficiency). The role of soils (biological and conventional farming systems) and Zn fertilizers in governing grain Zn concentration was assessed. Similarly, role of phosphorus (P) and Zn fertilizers in influencing Zn and phytate concentrations in wheat grain was investigated. Nitrogen (N) nutrition and the role of N in grain Zn concentration was characterized. During terminal (post-anthesis) drought, the effects of Zn nutrition and genotypic differences in Zn efficiency and drought tolerance on plant growth and Zn and protein accumulation in grain were assessed...

3. Traore, K. Effects of soil amendments and drought on zinc husbandry and grain quality in Sahelian sorghum.

Degree: 2006, NARCIS

In developing countries, short supply of Zinc is limiting both crop yield and human health. Improving Zn bio-availability in staple foods would greatly improve public health. It¿s therefore a major challenge to design cereal production techniques resulting in higher Zn mass fractions (MF) in combination with a lower phytic acid (IP-6, the main form of phosphorus accumulation in the grain) MF. In northern Burkina Faso, soil and water conservation (SWC) and soil organic amendments (SOAs) techniques adopted by farmers have improved both water and nutrient availability which consequently increased crop yields. Potentially, this improvement in yield may also improve the bio-availability of Zn from staple foods. This research investigated possible modifications of SOAs as currently practiced by farmers, which increase both the quality and the yield of sorghum in the Sahel Advisors/Committee Members: Wageningen University, Leo Stroosnijder, Paul Struik, Tjeerd-Jan Stomph.
