The objective of this work was to evaluate the performance of soybean cultivars as a function of the application of organomineral fertilizer via foliar, to obtain high yields. The study was conducted at the municipality of Mineiros-GO, Brazil. The soil is classified as neosol quartzeneic ortic typical, with medium texture. The experimental design was a 5x3 factorial, totaling 15 treatments, corresponding to five doses of Potamol Plus® (0, 0.25, 0.5, 0.75 and 1 L ha-1) and 3 cultivars of (M7739, M8372 and TMG7062) in 4 replications. The data obtained was submitted to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model, for these were performed single and multivariate analyzes. The analysis of variance showed that the cultivar factor was significant for all variables. Significance was also observed in the dose factor for APR, LUG, LQG, REN, LDG, GTP and GCP. Interaction between factors (C x D) occurred in APR, LUG, LDG, LQG, LTG, GTP and GCP. Potamol Plus® organomineral fertilizer applied foliar at 30 (50%) and 45 (50%) days after sowing did not increase the productive performance of soybean cultivars M7739, M8372 and TMG7062. The cultivars M7739 and TMG7062 presented high yields (yield ≥ 70 bag ha-1).

Freshwater, an essential asset for the life of living beings and one of the main resources for the development of nations. About 70% of the freshwater on the planet is used by irrigated agriculture. In view of the increasing population density for food production, considering the limitations of agricultural processes, countless producers are looking for viable alternatives that provide them with greater production, irrigation being one of them. This bibliographic review aims to summarize information on the topic: Rationalization of Water Resources and Environmental Impacts in Irrigated Agriculture, based on searches in books, scientific articles, and publications by reputable organizations related to the topic. In these, aspects related to water scarcity, the challenges of irrigated agriculture, contamination of water resources, the reuse of water for irrigation, the quality of reused water, and adequacy of water for irrigation are dealt with. The need for conservation of water resources and awareness of the irrigator regarding the rational use of water and the environmental impacts inherent to the irrigation process is evident, therefore, the intention is to consolidate increasingly sustainable agriculture.

Brazilian agribusiness is heavily influenced by beef export. Thus, it is important to evaluate the quality and growth rate of forage species used as cattle food. Given that the structural organization of leaf cells and tissues is directly related to forage-plant growth, we aimed to analyze the foliar anatomy of Urochloa brizantha and U. ruziziensis subjected to different fertilization management practices. Experimental design was completely randomized split-split-plots. Plots were allocated to fertilization strategies, namely single and split fertilizer application. Subplots were allocated to two fertilizer doses for the carrying capacities of 7 and 10 head of cattle per hectare (AU ha-1). Sub-subplots were distributed to the forage plant species U. brizantha and U. ruziziensis. Three leaves were collected from each treatment for the anatomical processing of cross-sections, epidermal imprints and diaphanizations. Based on a parsimonious model, U. brizantha showed thicker leaf tissues than U. ruziziensis. Split fertilizer application increased thickness of the adaxial and abaxial cuticle and of bulliform cells. Fertilizer dose of the higher carrying capacity determined increased thickness of the leaf blade, bulliform cells, and regular homogeneous parenchyma on both studied species. We concluded that increased fertilizer dose and split application interfere with the leaf anatomy of U. brizantha and U. ruziziensis, providing both species with enhanced growth and yield.

Due to its important participation in the agribusiness model worldwide, soybean actively drives national economies in producing countries. However, biotic and abiotic factors caused by pests and climate changes, respectively, can disrupt its productivity and consequently the business market. For this reason, the development of plants more tolerant to these negative environmental elements has been frequently one of the goals of scientific research. In the pipeline to obtain genetically improved plants, tissue culture protocols often represent a bottleneck, since the efficiency at this stage can be genotype-dependent. Therefore, the objective of this work was to evaluate the root regeneration process of two soybean genotypes (BRS 283 and BRS 537) in four different substrates (vermiculite, sand, medium containing activated charcoal and, control – MS medium and glucose). The rooting development was measured by the root’s length (cm²), dry mass (mg), volume (mm³), surface area (mm²), and diameter (mm). Results showed that in the activated charcoal medium, for both soybean genotypes, roots grew longer and presented a higher dry mass of roots, and root length when compared to vermiculite and sand substrates. We concluded that the efficiency of tissue culture is genotype-dependent since assayed genotypes presented phenotypical responses significantly different. The supplementation of tissue culture medium with active charcoal improved root growth for both genotypes. Therefore, it is likely that this medium can be also successfully applied to other soybean genotypes, or to other crops with similar tissue culture procedures to promote better rooting and plant establishment in further developmental stages.

Wheat represents an important staple food for human and animal nutrition. However, it constantly suffers from the incidence of biotic and abiotic stresses which reduce yields and kernels quality. The goal with this study was to use the elicitors Acibenzolar-S-Methyl and Carrageenan to elicit the mechanisms of defense of wheat to increase kernels quality and yields. The work was conducted as a random block design with six treatments and two wheat cultivars (TBIO Audaz and TBIO Noble) in Chapecó, SC, Brazil during the harvest season of 2020. Parcels had a size of 5.0 m2 and were spread apart by 80 cm of distance. The incidence of foliar/ear diseases, seed pathological and mycotoxicological (deoxynivalenol - DON) analyses were performed. The best dosage of carrageenan (Algomel PUSH®) for wheat plants has been accessed during this work. The use of the elicitors combined with the time of application, the proximity of the parcels and the drastic climatic conditions encountered in 2020 for the area of study did not result in significant yield gain nor in kernels quality. A weak correlation between Fusarium Head Blight and DON accumulation was observed. The elicitors showed to be a great tool for the suppression of foliar diseases for a period of roughly 20 days. The best dose-response of carrageenan is of 1.21 L ha-1.
小麦是人类和动物营养的重要主食。然而，它经常受到生物和非生物胁迫的影响，从而降低产量和籽粒质量。本研究的目的是利用激发子酸苯并- s -甲基和卡拉胶来揭示小麦防御机制，以提高籽粒品质和产量。该试验采用随机区组设计，于2020年收获季节在巴西南卡罗来纳州Chapecó采用6个处理和2个小麦品种(TBIO Audaz和TBIO Noble)进行。包裹大小为5.0 m2，间隔80 cm。进行叶面/穗部疾病发生率、种子病理和真菌毒理学(脱氧雪腐镰刀菌醇- DON)分析。在此过程中，我们确定了小麦植株的最佳卡拉胶(Algomel PUSH®)用量。使用诱导剂，结合应用时间，地块的邻近以及研究区域在2020年遇到的极端气候条件，并没有导致显着的产量增加或籽粒质量。赤霉病与DON积累呈弱相关。在大约20天的时间里，激发子显示出对叶面疾病的抑制是一个很好的工具。卡拉胶的最佳剂量效应为1.21 L ha-1。

Sweet sorghum is a special purpose sorghum with a sugar-rich stalk, almost like sugarcane. The objective of this work was to evaluate the phenotypic stability and adaptability of sweet sorghum genotypes, in different Brazilian regions, for the production of bioethanol. Twenty-five sweet sorghum genotypes were evaluated in 10 environments distributed in the Southeast, Midwest, Northeast, and Southern regions of Brazil. The experimental design was a randomized complete block design with three repetitions. The following agroindustrial traits were evaluated: fresh biomass yield (FBY), total soluble solids content (TSS) and tons of Brix per hectare (TBH). The adaptability and stability analyzes were performed with the methods GGEbiplot and Annicchiarico methodologies. The Annicchiarico and GGEbiplot adaptability and stability study methods presented satisfactory and consistent results and can be used separately or together in sweet sorghum breeding programs, and B005 and B008 sweet sorghum genotypes presented superior performance, with similar classification in both methods studied.

The objective of this work was to evaluate the performance of soybean seedlings in different seed treatments. The experiment was conducted in the municipality of Mineiros, GO. The soil was classified as Quartzarenic Entisol. The experimental design was randomized blocks in factorial 5x4, corresponding to seed treatments (Water, Cruiser, Fipronil Alta, Fortenza and Standak Top) in four soybean cultivars (Bonus, Ultra, Extra and BKS7830), in four replications. Before planting, pre-planting desiccation was performed. The fertilization used was 450 kg ha-1 of fertilizer 05-25-15 applied in the furrow and in a single dose next to the sowing. During the conduction of the experiment the control of pests, diseases and weeds were carried out as necessary, respecting the best practices and integrated management. The data obtained were subjected to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model. Uni and multivariate tools were applied. The analysis were performed at the interface Rbio and R. The interaction of soybean cultivars and types of seed treatment showed variations in all analysis evaluated in soybean seedlings. The best performances were verified among the cultivars BKS7830 that expressed the largest shoot fresh matter when submitted to Cruiser seed treatment, while the highest root length was expressed in the cultivar Ultra in the Fortenza seed treatment.

The GxE interaction is one of the major difficulties of plant breeding programs, both in the selection phase and in the recommendation of cultivars. To assess adaptability and stability, various statistical methods are used. The simultaneous use of some methodologies, using multi-information criteria for cultivar’s recommendation, can extract information that cannot be observed using each methodology separately. The aim of this work was to perform a large description of the behavior of flooded-irrigated rice genotypes, responding to environmental variations, using methods already established in the literature, but exploring the particularities of each methodology that together establish an information criterion for cultivar recommendation. To this end, 18 rice genotypes belonging to flood-irrigated rice breeding program were evaluated over four agricultural years, 2012/2013 to 2015/2016, totaling 12 environments (3 sites × 4 years). Multi-information estimates were performed to adaptability and stability analysis. There was no sign for the effect of the genotypes, and there was the significance of the effects of environment and GxE interaction. The aggregation of information and the large description of the behavior of the flooded rice genotypes demonstrated to be an efficient tool for studies of adaptability and stability.

This study aimed to evaluate the effect of biostimulant positioning on common bean cultivars in the southwestern Goiás conditions. The experiment was conducted in the municipality of Mineiros-GO. The experimental design was a randomized block in factorial 6x3, corresponding to the positioning of the Triplus® biostimulator (R5, R5 + R8 and water) in six common bean cultivars (BRS Campeiro, BRS Esteio, BRS Estilo, BRS Marfim, BRS Notavel and BRS Perola) in 4 replicates. The following productive attributes were evaluated: number of pod, number total of grains, number of commercial grains, number of non-commercial grains, mass of commercial grains, thousand grains mass. There was a significant interaction between cultivar x biostimulant as well as the factors alone. At the end of the experiment, it was concluded that the positioning of the biostimulant via foliar in the R5 phenological phase provided the highest yields for all common bean cultivars, especially BRS Estilo (43.87 sc ha-1) and BRS Notavel (43.02 sc ha-1). Biostimulant applications at stage R5 promoted the best results for number of non-commercial grains, mass of commercial grains, thousand grains mass. In the three stratifications used in the dendrogram, it was possible to form two groups of genotypes. Number total of grains, number of commercial grains and number of pod positively correlate with yield.
