The objective of this study was to characterize the physical and chemical attributes of Argissolo and Gleissolo in areas under different uses and landforms in the municipality of Areia, PB, Brazil. Areas with different uses were selected, such as banana (Musa parasidiaca), pasture (Brachiaria brizantha), reforestation with ‘sabiá’ (Mimosa caesalpiniaefolia), and open tropical forest, as well as two relief positions (foothill and mid-slope). Samples were taken from the 0.00-0.20 and 0.20-0.40 m layers. The samples were then air-dried, crumbled, and passed through a sieve with a 2 mm mesh to obtain fine air-dried soil. Physical, chemical, and fertility analyses were carried out and cation exchange capacity, sum of bases, and base saturation were calculated. According to the results, in general, the soil physical and chemical attributes were altered by land use and landforms. Soil organic matter levels in the surface layer were higher in the deposition foothills, while in the mid-slope the forest environments (natural or forested) showed higher levels of organic matter.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41620099","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}

Only mother and daughter plants were treated twice with the rhizobacteria. Plants not treated with rhizobacteria constituted the control treatment. Our results show that rhizobacteria affect different underground tissues and nematodes in third-generation banana plants. Helicotylenchus spp., Meloidogyne spp., Pratylenchus spp., Radopholus similis, and Rhabditis spp. were the nematodes found in banana roots. R. similis population and the damage in the root system of banana plants were reduced significantly by the rhizobacteria edaphic application.

These effects can be mitigated with the cultivation of salinity-tolerant varieties. The objective of this study was to evaluate the effect of salinity on the water imbibition curve during the germination process in cowpea seed and the response of different cultivars. An experiment was conducted in a factorial scheme, composed of three cultivars (BRS Marataoã, BRS Pajeu and BRS Tumucumaque) and four levels of salt stress, obtained by NaCl solutions at concentrations of 50, 100 and 150 mM and control, distilled water. The treatments were arranged in a completely randomized design, with four repetitions. The variables analyzed were the pattern of imbibition curve and final seed water content. It was found that the evaluated cultivars do not present the three-phase pattern for the seed soaking curve, in the absence or presence of salinity. There is variability for the pattern of the seed soaking curve among BRS Marataoã, BRS Pajeu and BRS Tumucumaque cowpea cultivars. Salinity acts by reducing the water content of cowpea seeds during the germination process and causes alteration in the pattern of the water soaking curve by the seeds. The cultivar BRS Tumucumaque shows higher tolerance to the reduction of seed water content under salt stress conditions when compared to the cultivars BRS Pajeu and BRS Marataoã.","PeriodicalId":55957,"journal":{"name":"Revista de Agricultura Neotropical","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49509404","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}

Research in this area has increased recently, bringing new information and guidelines to support national production and provide a technical basis for improving planting and cultivation techniques. The present study aimed to evaluate the influence of different light supplementations (Control - environmental condition, 400 µmol m-2 s-1, 600 µmol-2 m s-1, and 800 µmol m-2 s-1 ) on the production of hops seedlings in a greenhouse. We found that the responses are distinct among the cultivars used, but light supplementation increases variables related to physiological processes and seedling growth. Thus, we conclude that light supplementation with photosynthetically active radiation is advantageous for the production of hops seedlings since positive effects were found on the physiological characteristics of gas exchange related to photosynthesis and plant development when 400, 600, and 800 µmol m-2 s-1 were applied.
