Sustainable agriculture relies on effective soil management, making it crucial to assess health, especially in areas of agricultural expansion, such as the Cerrado MATOPIBA region. strategies, integrated production systems (crop–livestock–forestry), are essential mitigate these impacts. However, little is known about effects microbial communities. The objective this study was evaluate bacterial communities associated with soils under different Soil samples from 0–10 cm depth layer were...
Conservation systems involving trees enhance the sustainability of tropical soils. However, little is known on effect integrated with native and exotic soil chemical quality in eastern Amazon. We aimed to measure changes production Pindaré-Mirim, Maranhão, Brazil. This study was carried out 2017 2018, evaluating (i) perennial pasture; (ii) crop–livestock–forest integration-I (CLFI-I)—eucalyptus rows interspersed maize + Urochloa brizantha intercropping; (iii) CLFI-II—babassu palm (Attalea...
ABSTRACT The aim was to evaluate the productive performance and nutrient export of maize intercropped with drought-tolerant forage grasses. experimental design a randomized blocks in 2x2x2+1 factorial scheme (two grasses species – Massai Buffel; two sowing methods - furrow broadcast; times anticipated simultaneous; monoculture as an additional control), three replicates. maize+forage intercropping promoted greater competition for resources, especially water, limiting N uptake, chlorophyll...
The savanna (Cerrado) of northeastern Brazil has undergone significant transition in land use to expand agricultural activities. In this region, soils are highly weathered, with phosphorus (P) commonly bound aluminum (Al) and iron (Fe), creating conditions that demand the supply P fertilizers build soil fertility. Conservation systems, such as integrated agroforestry, can increase inorganic lability. aim study was evaluate availability components an agroforestry system. Four systems were...
No sistema de produção plantas, incluindo a melancia, o substrato tem importância considerada no desenvolvimento mudas, que vai influenciar não só na germinação, mas em um aumento considerável produção. Por esta razão com presente trabalho objetivou-se avaliar utilização do caule decomposto babaçu como mudas melancieira, cultivar Crimson Sweet. O experimento foi conduzido Centro Ciências Agrárias e Ambientais (CCAA), da Universidade Federal Maranhão (UFMA). Foi adotado delineamento...
Objetivou-se com este trabalho avaliar a germinação e biometria de mudas açaizeiro em substratos diferentes proporções caule decomposto babaçu (CDB).Em delineamento inteiramente casualizado foram testados os tratamentos: S1= 100% solo; S2= 80% solo 20% CDB; S3= 60% 40% S4= S5= S6= 4 repetições plantas por parcela.Foram avaliados: o percentual (G%); tempo médio (TMG); número folhas (NF); altura da planta (AP); diâmetro do (DC).Os dados obtidos submetidos à análise variância pelo teste "F"...
The objective of this study was to evaluate the biological rhythm vegetative growth and nutrient content yellow passion fruit seedlings produced in substrates with different levels based on decomposed stem babassu (DBS): S1 – 20%, S2 40%, S3 60%, S4 80%, S5 100% DBS S6: commercial. Were investigated plant height (PH), diameter (SD), emergency speed index (ESI), germination (%G), leaves number (NL), root length (RL), volume (RV), dry mass shoot (SDM), system (DMRS), Dickson quality (DQI)...

Phosphate fertilizers when applied to the soil, besides being harvested by crops, promote a residual effect that can be offered subsequent crops. The objective of this research was evaluate phosphate fertilization maize cultivation on successor crop, cowpea, in Cerrado region Maranhao. carried out experimental area Federal University Maranhao (UFMA), located city Chapadinha, MA (3°44'30"S, 43°21'37''W). design randomized blocks, with six treatments and four replications. were composed...
In Maranhão babassu forest, the decomposed biomass (DBB) has been used empirically by several farmers for production of Jacaranda mimosifolia seedlings. This study aimed to evaluate potential DBB as a substrate. The substrate compositions were S1: 100% soil (control); S2: 20% DBB; S3: 40% S4: 60% S5: 80% and S6: DBB. experiment was carried out from October December 2019 at Federal University Maranhão, Chapadinha, Brazil. It observed use enhances emergency speed index germination percentage,...
In the cassava (Manihot esculenta Crantz) cultivation system, planting seedlings directly in field is widely used. However, establishment of plants by this method slow, taking about 15 days to start formation shoots and roots. The plant phase not very competitive, which leads uneven low-productivity areas. Production on substrates an alternative that can improve uniformity stand, as well allow more careful selection best propagules. Viability propagation depends substrate, must have ideal...
ABSTRACT In the Amazon-Cerrado ecotone, increased costs from non-organic inputs and transportation render substrates more expensive, prompting use of decomposed biomass native palm stem for seedlig production. The study was carried out with objective evaluate physicochemical characteristics babassu palms (BDB), carnauba (BDC), buriti (BBU) compared to commercial substrate (SC) via multivariate analysis. This employed a database comprising 90 substrates, obtained Maranhão, Brazil farms. These...
High rates of limestone have been increasingly utilized in newly converted areas for grain production agricultural frontier regions to expedite the short-term correction soil fertility, leading compensatory yields. However, there is a lack information about different doses lime and gypsum soils Cerrado Matopiba, especially state Piauí, Brazil. The aim this study was evaluate effects soybean Southwest Piauí. carried out 2019/2020 2020/2021 crop years, on yellow Oxisol soil, randomized block...
