“…In sesame a 16-day difference in sowing resulted in 14 mg kg -1 less grain Zn in the late planted, whilst a sowing difference of 8 days did not show any significant effect on grain Zn and Fe concentration (Bhardwaj et al, 2014). In wheat, a 20-day difference in sowing resulted in high grain Zn concentration in early sown wheat compared to the late sown wheat (Hussain et al, 2023). In this study, a 6-day sowing difference could have a non-significant effect on Zn and Fe grain concentration, however this needs further investigation.…”

The concentration of mineral nutrients in plants is associated with bioavailabilities of soil mineral nutrients, which are regulated by various soil physio-chemical properties. A pot experiment was conducted to investigate the effects of soil type on grain and straw zinc (Zn), iron (Fe) and selenium (Se) concentrations of wheat/Amblyopyrum muticum and wheat/Triticum urartu doubled haploid lines. A set of 42 treatments in a factorial combination with 21 genotypes and two soil types collected from Ngabu and Chitedze Research Stations in Malawi was laid in a randomised complete block design (RCBD) in three replicates. Pre-experiment soil Zn and Fe were extracted using DTPA extraction method followed by analysis with inductively coupled plasma-mass spectrometry (ICP-MS). Aqua-regia hotplate acid digestion was used to extract soil Se and analysis was done using ICPM-MS. Grain and straw samples were digested using nitric acid digestion (HNO3) and analysed using ICP-MS. Soil analysis results showed that the two soils had the same textural class (Sandy clay loam), but different mineral concentrations, pH levels and percentage organic matter. Analysis of variance revealed a ~two-fold higher Zn concentration in grains grown in low pH, high Zn soils (Chitedze soils) compared to grains grown in high pH, low Zn soils (Ngabu soils). Variation in grain Zn concentration was associated with the genotypes (p = 0002), soil type (p = <0.0001), and their interaction (p = 0.035). Grain Fe was 1.3-fold higher in low pH than in high pH soils, and it was influenced by genotypes (p = < 0.0001) and soil type (p = <0.0001). Grain Se was highly associated with soil type (p = <0.0001), and it was 30-fold higher in high pH than in low pH soils. Straw Zn was generally higher in plants grown in Chitedze soils than Ngabu soils, whilst straw Se was higher in plants grown in Ngabu soils than Chitedze soils. The findings demonstrate the significance of soil physio-chemical properties for mineral accumulation and distribution to plant parts, thus informing future breeding programs on important considerations on crop genetic biofortification with the three mineral elements.

“…Most maize harvests in Nigeria is done manually because the predominant producers are smallholder farmers with limited or no capacity to afford the application of mechanical support [35]. The harvesting can be done either when the maize is fresh or dry depending on the need [36].…”

Maize products are very significant for domestic consumption as well as industrial uses both locally and globally. For there to truly appreciate the spread of maize production in Africa, the geospatial mapping and subsequent comparison of the value chain for Nigeria and Rwanda were necessitated hence the purpose of this study. Farm mapping geospatial techniques and remotely sensed data were used for both Nigeria and Rwanda in this study. GIMMS Global Agricultural Monitoring data from United States Department of Agriculture (USDA) were adopted for Nigeria and Rwanda. The crop calendars of both countries were examined which thereafter reviewed a marked distinction among them. The results of the agroecological zones for the two countries showed a significant variation in their distribution and types, which in turn affect both the planting and harvesting of maize; storage, marketing, processing, and policy framework for maize products value chain in Nigeria and Rwanda. Mapping of the two countries was carried out and the normalized differential vegetation index (NDVI) and the policy associated with maize value chains were checked and reported.

Water and nitrogen management influence on oil and protein concentration in maize

et al. 2023

The effects of water and nitrogen management on the oil and protein concentration of maize (Zea mays L.) grown in semiarid conditions are not well documented, although it is rather important for local consumers. The objectives of this study were, therefore, to determine the interaction between different nitrogen fertilizer rates and irrigation regimes on nitrogen uptake, and oil and protein content of maize grain.The importance of this study is to understand how the interaction of nitrogen and irrigation management affects the growth of maize and, thus, identify the best management practices to attain an optimal yield. A field experiment was conducted for 2 consecutive years in 2009 and 2010 using 5 nitrogen fertilizer rates, ranging from 100 to 300 kg N ha −1 , and 3 levels of irrigation management, ranging from 375 to 525 mm ha −1 , for a total of 15 treatments. The results showed that nitrogen accumulation in the maize plant linearly increased in applications up to 300 kg N ha −1 even under deficit irrigation (375 mm ha −1 ). For the application of 300 kg N ha −1 under optimum irrigation (525 mm ha −1 ), nitrogen accumulation in the plant's aboveground canopy was significantly increased (e.g., 145.7 and 144.3 kg ha −1 during 2009 and 2010, respectively) as compared to smaller N application rates. The combined nitrogen and irrigation regimes of 300 kg N ha −1 with 525 mm of irrigation resulted in the numerically maximum grain oil concentration, that is, 62 and 65 g kg −1 during 2009 and 2010, respectively, and protein concentration in grains, that is, 116 and 120 g kg −1 during 2009 and 2010, respectively. The regression analyses showed that the protein and oil concentrations of the grain are significantly and positively correlated with total nitrogen uptake. The nitrogen concentration in maize is driven by irrigation water and nitrogen fertilizer rates. Therefore, irrigation water and nitrogen fertilizers are the major inputs for not only improving maize grain yield but also maize grain quality.
