Sage and mountain sage belong to Lamiaceae family which have commercial importance from medicinal and aromatic plants in Turkey. The aim of this study was to evaluate the effects of different doses of selenium in salinity conditions on the morphological characteristics of sage (Salvia officinalis L.) and mountain tea (Sideritis sp.). Four different doses of selenium (5, 10, 20, 40 mg/l) were applied in without salinity (0) and salinity (250 mM NaCl/l) medium. The experiment was carried out in the split plot design with three replications in the climate chamber room of the department of field crops. When the examined properties were evaluated; plant height changed between 15.56-23.85 cm, number of branches 10.50-12.78 number/plant, number of leaves 52.78-92.00 number/plant, fresh leaf weight 2.48-7.51 g/plant, dry leaf weight 0.48-3.32 g/plant, fresh root weight 1.52-7.16 g/plant, dry root weight 0.19-1.24 g/plant, root length 26.18-36.07 cm, fresh shoot weight of 1.13-7.15 g/plant and dry shoot weight 0.13-0.38 g/plant. In mountain tea, the properties were determined for plant height as 3.26-5.93 cm, for number of branches as 2.50-6.33 number/plant, for number of leaves as 28.22-91.14 number/plant, for fresh and dry leaf weights as 2.42-11,03 and 0.45-1.91 g/plant, for fresh and dry root weights as 0.71-3.97 and 0.18-0.74 g/plant, for root length as 14.78-33.26 cm, for fresh and dry shoot weights as 0.29-2.28 and 0.12-0.41 g/plant were determined. As a result of this study, 5 mg/l selenium application in salinity conditions in both plants has reached high values in terms of fresh leaf weights. In addition to this, it was found that selenium applications in salinity conditions had positive effects on dry leaf weight in sage and fresh root and fresh shoot weights in mountain tea. As a result of correlation analysis, positive correlations were found between dry leaf weight and other characteristics especially in mountain tea in terms of traits examined in both plants.

Abstract Sorghum is a cereal crop that has the potential to be developed as animal feed. Sorghum plant experiencing drought stress will decrease their productivity. Efforts to overcome this problem are by adding mycorrhizae. Mycorrhizae increase the ability of plants to adapt to the environment in the form of absorption of water and nutrients. This study aimed to determine the productivity of sorghum (plant height increase, plant length increase, number of leaves and stem diameter) and fresh weight of sorghum plant. The research treatments were mycorrhizal levels and watering frequency using a completely randomized design with a 3x3 factorial pattern. The mycorrhizal fungi provision consisted of three levels, namely without mycorrhizal (M0), mycorrhizal 10 g/polybag (M10), and mycorrhizal 20 g/polybag (M20). The frequency of watering consisted of watering everyday (A1), watering every four days (A4), and watering every eight days (A8). The provision of mycorrhizae significantly affected the productivity of sorghum and fresh weight of sorghum (p<0.05). The difference in watering frequency affected the increase in sorghum plant height (p<0.05). However, it did not significantly affect the increase in length, stem diameter, number of leaves, and fresh weight of sorghum. In conclusion, mycorrhizae can significantly improved the productivity of sorghum plants developed in areas with high drought levels.

Silicon is a beneficial nutrient that has the potential to alleviate the abiotic stress of bok choy grown under salinity stress on entisols. Indonesia has wide areas of entisol soils along its coastline, which could be planted with bok choy. However, salinity conditions pose a problem in entisol soils. The objective of this research was to evaluate the effect of silicon on the agronomic performance of bok choy grown on an Entisols under salinity stress conditions. This research was conducted at the screen house of the Faculty of Agriculture, Jenderal Soedirman University, from May to August 2019. The experimental design was a completely randomized completely block design (RCBD) consisting of 16 treatments with three replications. The treatments comprised two factors: the dosage of silicon fertilizer, which was 0, 5, 10, or 15 g pot-1; and salinity stress, with a level of 0, 1, 2, or 3 dS m-1 pot-1. Observed variables included plant height (cm), number of leaves (strands), leaf area (cm2), fresh shoot weight (g), dry shoot weight (g), fresh root weight (g), dry root weight (g), fresh plant weight (g), and dry plant weight (g). The results showed that the provision of silicon (Si) fertilizer from zeolite and sugarcane bagasse compost (SCB) improved plant height, number of leaves, leaf area, fresh plant weight, and dry plant weight of bok choy plants under salinity stress conditions on entisol soil. At a silicon dosage of 10 g pot-1, fresh plant weight (production of bok choy) was 64.18% greater compared to the control. Increasing soil salinity up to 3 dS m-1 of soil decreased the plant height and number of leaves but did not significantly affect fresh shoot weight, dry shoot weight, fresh plant weight, dry fresh plant weight, fresh root weight, or dry root weight.

Rice (Oryza sativa L.) is a staple food crop in many countries in Africa. Africa consumes 11.6 million tons of rice per annum and out of 39 rice-producing countries, 21 import 50% to 99% of their rice requirements. The inability to reach the yield potential that would sustain Africa’s need for rice is due to many biotic and abiotic constraints that rice production faces. In lowland grown rice, one of the abiotic factors hindering rice production is iron toxicity. Excess uptake of ferrous (Fe2+) ions leads to a physiological stress, which results, into poor production. The current study aimed at selection of varieties tolerant to iron toxicity and assessment of the genetic diversity linked to this trait. In a hydroponic experiment conducted in a screen house at Africa Rice Centre in Dar es Salaam, 32 rice varieties were evaluated for tolerance to iron toxicity. The experiment was laid out in a split plot design with iron concentration as the main plot factor and variety as the sub plot factor. Two levels of iron concentration were used: 2 ppm and 300 ppm of Fe2+ as control and test concentrations, respectively. Traits observed to gauge tolerance were leaf bronzing (an indicator of iron toxicity), plant height, tillering, number of leaves, shoot weight (above ground), root length and root weight. The varieties ARICA8, and CK801 were found to be tolerant due to low bronzing indices, higher shoot weight, more number of leaves and lack of significant variation in morphology between the two Fe treatments except for the plant height. Correlation analysis depicted negative correlation between leaf bronzing and the other traits measured especially shoot biomass.
