Abstract Land degradation by deforestation adversely impacts soil properties, and long-term restoration practices have been reported to potentially reverse these effects, particularly on microorganisms. However, there is limited knowledge regarding the short-term effects of bacterial community in semiarid areas. This study evaluates soils experiencing (due slash-and-burn deforestation) (utilizing stone cordons revegetation), comparison a native Brazilian region. Three areas were selected:...
This study aimed to estimate genetic and phenotypic parameters provide knowledge for breeding programs aiming at the selection of main characters assessment in soybeans. The experiment was installed Sabia farm, located ‘Serra das Laranjeiras” , municipality Currais, Piaui, Brazil, during 2011/2012 crop year using a randomized block design with 27 genotypes three repetitions. evaluated variables were: height flowering (APF), maturity (APM), pod insertion (AIV), grain yield (PG), number nodes...
Extreme weather events, such as severe droughts, pose a threat to the sustainability of beef cattle by limiting growth and development forage plants reducing available pasture for animals. Thus, search species that are more tolerant adapted soil water deficit conditions is an important strategy improve food supply. In this study, we propose utilizing mathematical concept Manhattan distance assess variations in morphological variables tropical grasses under water-limited conditions. This...
Silicon (Si) fertilization is widely recognized to improve the development of crops, especially in tropical soils and cultivation under dryland management. Herein, our working hypothesis was that Si stoichiometry favors efficient use carbon (C), nitrogen (N), phosphorus (P) sugarcane plants. Therefore, a field experiment carried out using 3 × factorial scheme consisting three cultivars (RB92579, RB021754 RB036066) forms application (control without Si; sodium silicate spray at 40 mmol L-1...
The Metarhizium anisopliae complex consists of 34 formally described phylogenetic species. sensu lato has been used for decades in Brazil as a biological control agent controlling spittlebugs sugarcane plantations. We investigated the identities isolates mycoinsecticide formulations through multilocus analyses and morphological characterization species delimitation. A well-supported clade containing only from this study formed sister group with M . stricto, which we new taxon, mendonceae sp....
Searching for crop cultivars that are resilient to environmental stresses is crucial maintaining global agricultural production. Our study aimed screen semiarid-adapted cotton performing well under water-restricted conditions. Trials were conducted in a greenhouse involving six (FM 911, FM 912, 970, 974, 978, and 985) subjected four water levels (100, 80, 60, 40% field capacity—FC). At 20 days post-drought imposition, the growth, leaf succulence, osmotic potential, gas exchanges,...
Soil biological properties are sensitive indicators of land use changes. In particular, they have been widely used to assess the effects degradation and restoration. this study, we evaluated soil in degraded short‐term (<5 years) restored lands Brazilian semiarid region determine whether restoration efforts can enhance these properties. This study assessed three scenarios: native vegetation, land, land. Land resulted from deforestation, which exposed erosion, while involved constructing...
ABSTRACT Plant growth-promoting bacteria (PGPB) are found in plant tissues and promote growth by secretion of hormones enzymes, or facilitating the nutrient uptake. This study assessed forty PGPB isolates to determine their effects on maize sorghum growth. These were also compared with uninoculated plants, as negative (-N; without N fertilization) positive (+N; controls. height, stem diameter, shoot root dry mass, leaf accumulation chlorophyll content evaluated. For both sorghum, diameter...
Identifying cultivars of leguminous crops exhibiting drought resistance has become crucial in addressing water scarcity issues. This investigative study aimed to select soybean and cowpea with enhanced potential grow under restriction during the vegetative stage. Two parallel trials were conducted using seven (AS3810IPRO, M8644IPRO, TMG1180RR, NS 8338IPRO, BMX81I81IPRO, M8808IPRO, BÔNUS8579IPRO) (Aracê, Novaera, Pajeú, Pitiúba, Tumucumaque, TVU, Xique-xique) four levels (75, 60, 45, 30%...
Abstract A high frequency of plants showing symptoms wilting and root rot has been observed in tomato‐producing areas Santarém Belterra, Pará, Brazil. These showed ranging from yellowing to wilting, with roots displaying reduced development darkening the xylem. Four fungal isolates, derived a collection 12 obtained symptomatic plants, were chosen for identification using both morphological phylogenetic species concepts. To determine identity fungi, DNA was extracted used PCR reactions....
Objetivou-se, com este trabalho, avaliar a interação física entre misturas em tanque de diferentes classes defensivos agrícolas. O experimento foi conduzido no laboratório Química da Universidade do Estado Mato Grosso, período junho agosto 2010. Os tratamentos foram constituídos pelas seis herbicidas (glyphosate SC, glyphosate WG, lactofen CE, fomesafen haloxifop-R CE e fluazifop-pbutil EW) inseticidas (methomyl CS, clorpirifós teflubenzuron triflumuron cipermetrina tiametoxam +...
ABSTRACT Cowpea is broadly cultivated worldwide, especially in semi-arid or arid regions where soil irrigation water salt contents can negatively influence the species’ productive capacity. The objective of this study was to evaluate morphophysiological responses cowpea genotypes salinity. experiment conducted a greenhouse, under completely randomized design with nine replications and 5x3 factorial scheme. Treatments consisted five levels electrical conductivity - EC (EC0: 0.55; EC1: 1.60;...

We used temperature and precipitation data 4,942 cities collected NASA / POWER platform 1990 2020 elaborate current scenario. The scenarios were obtained using CHELSA (Climatologies at high resolution earth's land surface areas) corresponded periods 2041-2060 2061-2080 associated with four scenarios. spatialization...
The Caatinga biome in Brazil is renowned for its rich aboveground biodiversity. However, approximately 19% of this has experienced desertification, severely affecting the soil microbiome. Monitoring these microbial communities essential to understanding impacts desertification and potential outcomes restoration efforts. Microbiome Initiative aims assess microbiome areas undergoing those under Brazilian drylands. This initiative seeks explore core their functions, including overlooked groups...
