“…This finding is similar to that reported by Rosas et al, (2007) and Inostroza-Blancheteau et al, (2017) in ryegrass from Chilean Andisol. In contrast, recent studies in maize (Silva et al, 2017) and barley genotypes (Huang et al, 2015) showed that some Mn-tolerant genotypes exhibited higher Mn concentrations in shoots than in roots due to internal tolerance mechanisms.…”

“…Thus, Barke, Tatoo and Sebastian showed higher SOD production in roots at increasing Mn doses. This mechanism could be involved in tolerance against oxidative stress, to convert superoxide radicals into hydrogen peroxide and water, playing a principal role in the defense against excess Mn in tolerant plants (Sharma et al, 2012;Silva et al, 2017). Meanwhile, POD increased in the shoots of all cultivars.…”

Manganese (Mn) is an essential micronutrient for plants, and is necessary for biochemical and physiological processes. The objective of this research was to determine the early responses to Mn excess and its relation to antioxidant performance mechanisms and organic acid exudation in commercial barley cultivars. We determined early responses to Mn excess in four barley cultivars (Barke, Tatoo, Scarlett, Sebastian), which were subjected to increasing Mn concentrations (2.4-150-350-750-1500 µM Mn), pH 4.8, under nutrient solution during seven days. Results showed that plant growth parameters: biomass, length and relative growth rate (RGR) were negatively altered with the higher Mn treatments. Antioxidant performance such as antioxidant activity (AA) and antioxidant enzymes such as superoxidase dismutase (SOD) were activated in presence of excess Mn. Oxalate was the major organic acid roots exudate, and the cultivar Sebastian had the highest oxalate exudation. In conclusion, Tatoo and Sebastian are proposed as the most Mn tolerant cultivars given that the biomass parameters were not affected by increasing Mn doses, showing major oxalate exudation. It is suggested that the mechanisms associated to Mn alleviation could be attributed to SOD, AA and organic acid production, mainly oxalate, in tolerant cultivars (Sebastian, Tatoo) together to significant decrease of total phenols (TP) in shoot of sensitive cultivars (Barke and Scarlett). Non-enzymatic barriers were not related to early responses, and an enzymatic barrier and oxalate exudation were considered as early indicators of Mn stress, projecting that the tolerance of Mn-tolerant cultivars could increase under field conditions.

The present study aimed to assess the effects of combinations of doses of phosphorus and calcium on the yield characteristics of Macrotyloma axillare access NO 279 (family Fabaceae) in a Red-Yellow Argisol with average P level (24 mg dm-3). The experiment was carried out in greenhouse in Nova Odessa/SP, Brazil, from August to December 2015. A 52 fractional factorial design with 13 combinations for doses of phosphorus and calcium in mg dm-3: 0-0; 0-40; 0-80; 15-20; 15-60; 30-0; 30-40; 30-80; 45-20; 45-60; 60-0; 60-40; 60-80, in a randomized complete block design with four replications. Two cuttings were made on the plants. The phosphorus x calcium interaction and the isolated doses of calcium were not significant for the parameters assessed. The production of dry biomass of the aerial part, the leaf area, the number of leaves and the number of branches of Macrotyloma showed significant responses to the isolated doses of phosphorus applied in the primary growth. In the secondary growth, only the number of branches and the dry biomass production of the dead material responded to the doses of phosphorus. Phosphorus was a modulator of dry biomass production of roots and of the production of nodules and the number of nodules of macrotyloma. The content of calcium present in the soil, together with the increase of the value of base saturation to 50%, was sufficient for the establishment and growth of the legume. Therefore, a supplemental dose of this nutrient was not required.

The existence of genotype and environment (G x E) interaction causes difficulty in selecting suitable varieties of soybean in an agroforestry system based on kayu putih stands. This study aimed to determine the suitability of adaptive, stable and high yield soybean varieties in an agroforestry system based on kayu putih stands by using GGE-Biplot analysis. The experiment was conducted from May to August 2018 at Menggoran Forest Resort, Playen District, Gunung Kidul Regency, Special Region of Yogyakarta, Indonesia. The experiment was conducted using a randomized complete block design (RCBD) with five block as replications. The first factor was soil type in Menggoran Forest Resort, consisting of Lithic Haplusterts, Vertic Haplustalfs and Ustic Endoaquerts. The second factor was soybean varieties, consisting of Anjasmoro, Argomulyo, Burangrang, Dering I, Devon I, Gema and Grobogan. The observation was carried out on seed dry weight of soybean per hectare. The data were analyzed using Combined Analysis of Variance (ANOVA) with α = 5% and GGE-Biplot. Dering I was the most suitable varieties in an agroforestry system based on kayu putih stands and showed the mean of highest yield of 1.22 tons ha-1.
