The Orchidaceae family stands out when it comes to the commercialization of pot flowers, this is due to their flowers being widely attractive and have variability of colors, size and shapes according to the species; this results in plants with high relevance to the economy in the floriculture sector. The goal of this study was to elucidate questions about the effect of micronutrients on initial growth, the influence of electrical conductivity and frequency of fertilizer application, and the efficiency of organic fertilization with castor bean cake, on the growth and nutrition of Brassia verrucosa Lindley orchid. Studies with mineral fertilization involving nitrogen (N), phosphorus (P) and potassium (K) in Cattleya and Phalaenopsis seedlings allowed to obserevar that the N increment increased the number of flowers in Cattleya, while P and K did not affect this variable. The salinity of irrigation water also has an effect on growth and flowering. The electrical conductivity, the sources of fertilizers, their interaction with the substrate, the balance between the nutrients, the quantities and frequencies to be used, in addition to the different phenological requirements and characteristics intrinsic to the species, are important aspects to be considered in fertirigation.

Bromeliads are used in landscaping due to the beauty of their leaves and flowers. The use of plant regulators such as nitric oxide (NO) promotes the stimulus of germination and it has been a way out to enhance production and reduce the search for plants in nature and nanoencapsulation aims to optimize its effect. The objective of this work was to evaluate the effect of using free and nanoencapsulated NO donor on the germination of D. excelsa. The treatments consisted of soaking the seeds for 5 minutes with s-nitrosoglutathione (GSNO), chitosan/sodium tripolyphosphate nanoparticles containing GSNO (NP CS/TPP-GSNO) and empty (NP CS/TPP) at doses: 15 mM and 20 mM. The control consisted of imbibition in distilled water. For each treatment, 4 replications of 50 seeds were used. The following variables were evaluated: percentage of germination (GER), first germination count (FGC), germination speed index (GSI), mean germination time (t) in addition to the length (SL) and seedling dry weight (SDW). To characterize the seeds, water content and viability were evaluated. D. excelsa seeds had 9.9% water content and 64% viability. For GER, treatments with GSNO ranged from 43 to 60%.

The present work aimed to select populations for the breeding of common bean targeting fusarium wilt resistance and grain yield. Twelve carioca bean lines, which mainly differ in fusarium wilt resistance and grain yield, were crossed in a 6x6 partial diallel scheme. The parents and their 36 F1’s hybrids were evaluated for fusarium wilt severity caused by FOP isolate UFV 01 (FWS), and grain yield (YIELD). 34 F4’s populations, 12 parents and three other lines were also evaluated for grain yield per plant. The data of F1's parents and hybrids were submitted to diallel analysis. Using the grain yield data per plant, the potential of the 34 F4’s populations was predicted by the Jinks and Pooni method (1976). In the diallel analysis, BRSMG Talismã, CVIII 8511, BRS Pérola, VC 25 and VC 13 stood out in terms of the frequency of favorable alleles for FWS. Except for BRSMG Uai and IAC Formoso, these lines presented the most dominant genes associated in Fusarium wilt resistance. For YIELD, there was a predominance of dominant genes determining higher yield. The 20 F4’s populations with the highest potential included the best 12 of the 20 populations, based on diallel analysis for YIELD. Thus, the 12 populations received the addition of four that were highlighted only by the methodology of Jinks and Pooni (1976), and four based on diallel analysis, which totaled 20 populations. The use of information from more advanced inbreeding generations in complementarity with those of diallel is a promising strategy.

Sorghum (Sorghum bicolor [L.] Moench), a main food for more than 500 million impoverished and food insecure people in arid and semi-arid regions of Sub-Saharan Africa (SSA) and South Asia, is an important crop for food and nutritional security (SA). Sorghum has the most acceptance in these drought-prone areas due to its good tolerance to harsh settings, high yield, and use as a good source of forages. In this review, the objective of this study is to document the production and use Sorghum in improvement programmed through a literature review, we used publications from journals to explore gene families, how they evolved, gene family theories, how gene families influenced agronomic features in sorghum, and in-depth studies of the key ten gene families in sorghum. The future prospects on sorghum enhancement include genomic selections and gene families, as well as comparative genomic selections. Furthermore, understanding the mechanism of these gene families is important for addressing problems that plague sorghum production, including as infections, drought, and heat stress. We can accurately improve traits using modern techniques such as marker-assisted selection, Genomic selections (GS), Marker-assisted backcrossing (MABC), Marker-assisted recurrent selection (MARS), Marker-assisted selections (MAS), and Genome-wide selections (GWAS) if we have the above gene families of interest (GWAS). Sorghum as a desirable breed: future paths and prospects.

Because of a lack of direct measurements, the presence and persistence of glyphosate and its main metabolite aminomethylphosphonic acid (AMPA) in agricultural soils of Brazil remains unknown. This paper aims at reporting glyphosate and AMPA contents in Brazilian field crop soils at the country scale from southern states to eastern Amazon. Brazilian field crop farmers are among the highest users of glyphosate-based herbicides (GBH) in the world. Soybean and corn field crop soils from 17 sites were collected at two depths (i.e. 0-20 cm and 20-40 cm) in 2016 and 2018. The study area encompasses three regions of Brazil: southern Brazil, central-west Brazil and eastern Amazon, all having in common intensive, conventional, large-scale grain farming. ßGlyphosate and AMPA contents were measured using a GC-ECD following soil extraction. Both chemicals were ubiquitously detected in soils cultivated under various agricultural practices ranging from ploughing to no-till ones. Average measured glyphosate and AMPA contents were 0.08 ± 0.09 µg/g and 0.17 ± 0.16 µg/g respectively with maximum values of 0.57 µg/g and 0.98 µg/g. Glyphosate plus AMPA contents in the top 40 cm of soils presented cumulated amounts exceeding the annual glyphosate inputs via GBH. This is interpreted as a multiannual persistence of these chemicals in Brazilian agricultural soils. Downward migration of glyphosate and AMPA is also suspected with regard to the vertical distribution of these chemicals along with deeper soil horizons. This study highlights the backlash of conservation agriculture as far as glyphosate and AMPA presence in agricultural soils are concerned. These compounds persistence in Brazilian soils appear to be longer than what is usually reported in the literature, especially so for tropical environments. The worldwide concern about the ubiquitous presence of glyphosate and AMPA in the environment needs a broader screening in Brazilian field crop soils since the majority of the available data comes from Argentina, Europe and to a lesser extent North America.

It is essential to select soybean genotypes with high yield and adaptability to the Cerrado Biome, mainly related to the supply of phosphorus. In soybeans, studies on correlations involving their characters with phosphate fertilization are insipient. The objective of this work was to evaluate the phenotypic correlations of soybean under different concentrations of phosphorus, aiming to improve the selection and identification of the most promising characters regarding the possibility of gains in grain yield. The study was conducted in Mineiros, Goiás, Brazil. The experimental design used was in randomized blocks in factorial corresponding to four soybean genotypes in five levels of phosphorus. The soil tillage system was carried out conventionally. The crop treatments relevant to the control of weeds and pests were carried out following the best practices of integrated pest management. At the end of the experiment, the data were submitted to multivariate analysis of variance. The treatments differed, mainly due to the number of grains per plant, where their similars were grouped in clusters. The correlations between the characters were significant and pointed to affinities, in addition to the potential explanation for the yield. It is concluded that genetic factor is largely responsible for the soybean yield indices, however, this was also influenced by the concentrations of triple super phosphate as a phosphate source. And that in order to increase the yield of the soybean crop it is necessary to reduce the stand and plant height, as well as to increase the average of pods with three grains, pods per plant and grains per plant.

The use of foliar fertilizers has become the main innovation in the field of plant mineral nutrition. And the use of these micronutrients associated with multivariate tools can contribute to the technical development of agribusiness, especially in soybean. Therefore, the aim of this study was to verify the possible correlations between morpho-agronomic characters of soybean supplemented via leaf with micronutrients. The study was conducted under field conditions in the county of Mineiros, GO, Brazil. The experimental design used was in randomized blocks in a 3x5 factorial scheme corresponding to three soybean genotypes (Anta82, CD2737 and N7902) and five concentrations of leaf supplement, Triplus Anuais® with its guarantees of phosphorus 2%, boron 3.4%, molybdenum 1% and 0.35% nickel. The leaf supplement was applied in a single dose during pre-flowering (0, 300, 600, 900 and 1200 ml ha-1). The highest yield potential was observed in the NS 7209 IPRO genotype at doses of 300 and 600 ml of leaf supplementation via Triplus Anuais. In addition, field adjustments to increase the averages of pods with two grains, grains per plant and mainly pods per plant, can increase the yield of genotypes.

The nutritive value of a dual purpose forage, its structural and morphological composition, seed production capacity are determining characteristics in the selection of a genotype. The objective of this work was to evaluate the effect of cutting management on yield components, physiological quality of the seeds in the subsequent generation. Experiment I: the field cutting management was performed, and the yield components and the physiological quality of the seeds were evaluated. Experiment II: where the components of plant yield and physiological quality of the seeds were evaluated. The cutting managements affect the components of yield, such as thousand seed weight and seed mass per cob, as well as germination, first germination count and seedling dry mass of dual purpose wheat. In the generation that evaluates the quality of the seeds produced, the cuts do not influence the physiological quality of the seeds, however, they affect the yield components, number of cobs per plant, one thousand seed weight and seed mass per cob.

In the generation that evaluates the quality of the seeds produced, the cuts do not influence the physiological quality of the seeds, however, they affect the yield components, number of cobs per plant, one thousand seed weight and seed mass per cob.","PeriodicalId":297313,"journal":{"name":"Agronomy Science and Biotechnology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115103156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soybean is currently the main crop in national agribusiness. Phosphorus is a limiting nutrient in obtaining high yield, especially in the soil conditions of the Brazilian Cerrado. Thus, the objective was to analyze the effect of triple superphosphate doses on the yield of soybean genotypes under Cerrado conditions. The study was conducted in Mineiros, GO, Brazil. A randomized block design was used, in a 4x5 factorial scheme, corresponding to four soybean genotypes (AS3680, NA5909, NA7337 and TMG1180), in five levels of phosphorus (0, 100, 200, 300 and 400 kg ha-1 of P2O5) using Triple Superphosphate (41% P2O5 and 9% Ca), in 4 repetitions. The variables related to yield were evaluated at 146 days after sowing. Statistical analyzes were performed on the R Core Team (2019). The study revealed a significant interaction (p≤ 0.05) between soybean genotypes and phosphate doses, in addition to the significance (p≤ 0.05) in the main effects. The regressions were adjusted and estimated with optimal points close to 100 kg ha-1 of P2O5 for the different characters. Positive and negative correlations and their trends were considered among the variables for each soybean genotype, in addition to grouping the interaction of factors. The characters with the greatest contribution to raising yield levels were the thousand grain mass, plant stand and pods per plant. Using triple superphosphate as a phosphate source, it is recommended to grow the AS3680 genotype, which showed the highest yield (91.57 bag ha-1) with a dose of 95.65 kg of P2O5 ha-1, corresponding to 21.57% increments in yield.
大豆是目前我国农业的主要作物。磷是获得高产的限制性养分，特别是在巴西塞拉多的土壤条件下。因此，目的是分析三倍过磷酸钙剂量对塞拉多条件下大豆基因型产量的影响。这项研究是在巴西米内罗斯进行的。采用随机区组设计，4个基因型(AS3680、NA5909、NA7337和TMG1180)在5个磷水平(P2O5用量为0、100、200、300和400 kg ha-1)下，采用三磷酸(41% P2O5和9% Ca)，重复4次。播种后146天对产量相关变量进行评估。对R Core Team(2019)进行统计分析。结果表明，除主要效应显著(p≤0.05)外，大豆基因型与磷剂量之间存在显著交互作用(p≤0.05)。对不同性状的回归进行了调整和估计，最佳点接近100 kg ha-1 P2O5。分析了各大豆基因型变量之间的正相关和负相关关系及其趋势，并对各因素的相互作用进行了分组。对产量水平提高贡献最大的性状是千粒重、单株林分和单株荚果。以三元过磷酸钙为磷肥源，推荐种植AS3680基因型，当P2O5添加量为95.65 kg ha-1时，产量最高(91.57袋ha-1)，增产21.57%。

Although Brazil is one of the main agricultural countries in the world, it is historically an importer of wheat. For this reason, strategies aimed at the expansion of wheat in the country, to areas that are not traditionally producing (warmer), are of paramount importance. In wheat breeding, phenotypic values are usually used in simultaneous selection, however, they do not always correspond with genetic superiority. Therefore, the objective of this work was to evaluate the efficiency of five selection indexes applied to the genotypic values of wheat, the coincidence between the indexes and to select the most promising lines. For this, we evaluated a panel with 41 genotypes of tropical wheat, for the traits: days for flowering, disease note, plant height, hectoliter weight and grain yield. Data were submitted to REML/BLUP analysis to estimate genetic parameters and genotypic values. We applied on the BLUPs the rank summation index, multiplicative index, genotype- ideotype distance index, additive index and FAI-BLUP index. There is a genotypic variation shown by analysis of deviance for all evaluated traits. We presented different estimates of gains from selection according to the selection index applied. We observed higher estimates of gains from selection for additive and genotype-ideotype distance indexes. High similarity was observed in the selection of genotypes through the coefficient of coincidence between the indexes. Eight lines were selected simultaneously by three or more indexes. Lines VI 14047, VI 14774 and VI 14980 showed the best performance among the eight lines evaluated by the Z index.
