“…In the 2013/2014 season, there was smaller height of the soybean SYN 1059 plants in succession to the triticale IPR 111 culture, while the greater height occurred with the wheat BRS Tarumã crop (Table 3). These results are similar to those reported by Brandt et al (2006), who found no differences in the height of soybean plants when comparing succession systems in no-tillage, including oat and wheat. The lower height of the soybean in sucession to triticale in the 2013/2014 season can be attributed to the synergistic effects between the synchronization of the nitrogen mineralization-immobilization in the growth of soybean (Assmann et al, 2014) due to lower residual DM production provided by triticale (Table 2) (Santos et al, 2013).…”

“…Pereira (2013) found no significant effect between the predecessor cultivation of single corn and intercropping corn-brachiaria on the number of soybean pods, where single corn and intercropping provided 68 and 73 pods per soybean plant, respectively. Brandt et al (2006) evaluated the agronomic performance in soybean cultivars over predecessor crops, and found a number of 35 pods per plant. The authors claim that these values are considered normal for the good development of the crop.…”

The experiment was performed at a non-acclimatized protected screened environment. The objective of the study was to evaluate the influence predecessor crops of single and intercropping corn and brachiaria on soybean yield submitted to irrigation intervals. The experimental design adopted was in a split split-plot randomized block design with four repetitions. Two soil classes (dystroferric Red Latosol and dystrophic Red Latosol) were evaluated in the plots, three intervals between irrigations were used during the soybean flowering (each one day, two days and three days) in the subplots and three types straw in the crops autumn-winter (single corn, single brachiaria, intercropping corn and brachiaria) in the sub-subplots. The two soybean plants cultivated in polyethylene pots containing 20 liters of dystroferric Red Latosol or dystrophic Red Latosol corresponded to each repetition, according to the treatment. The irrigation intervals of three and two days, in dystroferric Red Latosol and dystrophic Red Latosol, respectively, with single brachiaria at the previous crop provided greater number and weight of pods, higher number of grains and higher soybean yield. Irrigation every three days with single corn at the previous crop in dystroferric Red Latosol and dystrophic Red Latosol, resulted in the lower soybean performance.

“…The evaluated characteristics were: a) plant height: measured using a ruler, across ten random plants in the plot in phase R5.3, according to the methods described in the study of (9,35); b) dry matter: evaluated using samples from ten plants per plot; the samples were placed in an oven with forced air circulation at 65 °C, until they reached a constant weight, according to the method of Brandt et al (2006); c) oil content: determined with 30 g (ground) of seeds from each plot using the Near Infrared Reflection (NIR) technique and expressed as a percentage (%), according to the method of Heil (2010); d) number of pods per plant: obtained by counting the number of pods per plant; e) number of grains per pod: obtained by counting the number of grains in the pods divided by the total number of pods; f) weight of one hundred seeds: determined according to the mass and total number of seeds per experimental unit; g) productivity: upon reaching physiological maturity (95% of the mature pods), the soybean plants were harvested from the two central rows of each plot, 4 m 2 , with a 0.5 m edge left unharvested. After harvesting, the plants were trailed, and the seeds were then weighed, after drying (12% humidity) and cleaning, to determine the grain yield of kg ha -1 ; (h) days for flowering: the days from emergence necessary to have an open flower in 50% of the plants of the plot; this characteristic was evaluated using ten plants chosen at random, according to the method employed by Carvalho (2014); and i) days for maturation: determined from the number of days from emergence necessary to have 95% of mature pods; this characteristic was evaluated using ten random plants in the plot, according to that method.…”

Influence of genotype-environment interaction on soybean (Glycine max L.) genetic divergence under semiarid conditions

et al. 2022

The objective of the present work was to evaluate the influence of the genotype–environment interaction on genetically divergent soybean grown under semiarid conditions. Four experiments were carried out in randomized blocks with four replicates to evaluate twenty-one soybean genotypes. The following descriptors were used to quantify divergence: plant height, dry matter, oil content, number of pods per plant, number of grains per pod, the weight of 100 seeds, yield, days for flowering, and days for maturation. The unweighted pair group method with arithmetic mean was used to group the genotypes from the Mahalanobis distance matrix estimated using the genotypic means estimated by the REML/BLUP method. The grouping of genotypes depended mainly on the effects of the interaction between genotypes and years. The joint analysis, without the effect of the interaction, allowed us to obtain two groups of genotypes. The most recommended crosses were those of the lines BRS Tracajá, BRS Pérola, BRS Carnaúba, M 8644 IPRO, BRS 8590, and BMX OPUS IPRO with the genotype BRS Sambaíba, especially the one between BMX OPUS IPRO and BRS Sambaíba. Highlights The grouping of genotypes is dependent on the evaluation conditions, mainly due to the effects of the genotype x years interaction. The use of estimates of the free genotypic means of the interaction obtained in the joint analysis may be a more adequate alternative to define the heterotic groups and, consequently, the crossings to be performed. The joint analysis, without the presence of the interaction effect, allows obtaining two groups of genotypes.
