Aluminum (Al) toxicity is one of the most limiting factors for productivity. This research was carried out to assess the influence of Al nutrient solution on plant height, dry weight and morphoanatomical alterations in corn (Zea mays L.) roots and leaves. The experiment was conducted in a greenhouse with five treatments consisting of Al doses (0, 25, 75, 150, and 300 µmol L-1) and six replications. The solutions were constantly aerated, and the pH was initially adjusted to 4.3. The shoot dry matter, root dry matter and plant height decreased significantly with increasing Al concentrations. Compared to the control plants, it was observed that the root growth of corn plants in Al solutions was inhibited, there were fewer lateral roots and the development of the root system reduced. The leaf anatomy of plants grown in solutions containing 75 and 300 µmol L-1 Al differed in few aspects from the control plants. The leaf sheaths of the plants exposed to Al had a uniseriate epidermis coated with a thin cuticle layer, and the cells of both the epidermis and the cortex were less developed. In the vascular bundle, the metaxylem and protoxylem had no secondary walls, and the diameter of both was much smaller than of the control plants.

A screen house study was conducted to evaluate the effect of gemstone mining on the growth behaviour of maize Zea mays L. A completely randomized design involving two samples of soil (FUTA (control) and Ijero (mined soil)), two varieties of the maize (TMZ234 and Sammarz 39) was used. The seeds were sown into experimental pots containing the soils and the whole set up was left for eight weeks. Growth parameters (plant height, leaf area and stem girth were taken at a weekly basis up till the eight week. Eight heavy metal (Cd, Cu, Cr, Fe, Ar, Zn, Pb and Ni) concentration in the soils, roots and shoots of the plants was determined at the end of the experiment using atomic absorption spectrophotometer. Baseline data indicates that the mined soil is acidic (pH 4.12), with low organic carbon (0.92), low organic matter (1.59) and low total nitrogen (0.76). Results obtained from this study show that all growth parameters were negatively affected by the mined soil. Plant height was significantly higher in the control varieties (82.28 and 40.46, respectively) when compared with the mined soil varieties (30.5 and 29, respectively) at 8 weeks after planting (WAP). Leaf area also followed the same pattern with varieties grown on control soil having significantly higher leaf area (48.22 and 25.22, respectively) than varieties grown on mined soil (19.08 and 19, respectively). Stem girth of variety TMZ234 in control soil was also significantly higher than the rest (2.24 as against 1.68, 1.5 and 1.74). Heavy metals concentration in the soil, shoot and root of the plants grown in mined soils were all higher than in those grown on control soils. In the soil, Cr, Ni and Pb were 0.24, 0.15, 0.10 and 0.20, 0.13, 0.10, respectively, in both varieties grown on mined soils as against 0.03, 0.01, 0.00 and 0.03, 0.08, 0.00 for Cr, Ni and Pb, respectively, for both varieties grown on control soils. Bioaccumulation and translocation factors for the metals were less than 1 in all the soils except for Ni which had BCF of 2.80 and 6.90 for both varieties grown in the control soils. The results from this study has shown the negative effect of gemstone mining activities on the growth of two varieties of Zea mays.

The research was conducted in October 2016 - February 2017 at Huta Sait Buttu Saribu, Pematang Sidamanik sub-district of Simalungun district, altitude of place + 1100 m asl. The purpose of this research is to understand the critical period of corn crops (Zea mays L.) due to weed competition in various soil systems. The research implementation methodology used a split plot design (SPD) with randomized block experimental design. The treatment consists of two factors, namely the land treatment system (T) as the main plot and the weed investment period (W) as the subplot. The soil processing system consists of 3 types, i.e. without soil treatment (T0), minimum tillage (T1), and intensive tillage (T2). While the investment period of weeds is designed in 10 treatments, namely W1 = free weed for 0-15 DAP, W2 = free weed for 0-30 DAP, W3 = free weed 0-45 DAP, W4 = free weed 0-60 DAP, W5 = free weed until harvest, W6 = weeds from planting to harvest, W7 = weeds for 0-60 DAP, W8 = weeds for 0-45 DAP, W9 = weeds for 0-30 DAP, and W10 = weeds for 0-15 DAP. Each treatment was repeated 3 times. To determine the effect of the two treatments, observation towards the dominance of weeds (summed dominance ratio), the period of silk delay (day), height of plant (cm), root dry weight (g), leaf area (cm2), and dry seed production per plot (kg) is done. From the result of research data analysis, noted that soil processing system is influencing the root dry weight, plant height, total leaf area and seed production per plot, but the period of silk delay is not influenced by difference of soil processing system. The difference in weed investment time affects the period of silk delay, plant height, root dry weight, leaf area and seed weight per plot. The interaction of both treatments affects plant height, root dry weight, leaf area, and seed weight per plot. But period of silk delay is not influenced by the interaction of the two treatments. From the research results, concluded that the critical period of corn crop growth due to weed competition occurs when in the period of 0-60 DAP weeds are allowed to compete with corn crops
