O feijão comum é uma planta exigente em nutrientes, principalmente em relação ao N. A adoção de um sistema de preparo que possibilite melhorar as condições do solo, associada ao fornecimento adequado de N pode ser de suma importância no sentido de aumentar a eficiência da planta na utilização dos recursos disponíveis. Assim propôs-se o estudo com o objetivo de avaliar o efeito de diferentes preparos do solo, inoculação de sementes com Rhizobium tropici e doses de N em cobertura no desenvolvimento e produtividade de grãos do feijão comum, cultivar Pérola, no período de inverno e irrigado. O experimento foi desenvolvido no município de Selvíria (MS) nos anos de 2006 e 2007. O delineamento estatístico foi blocos casualizados disposto em esquema fatorial 3 x 2 x 4, envolvendo três modalidades de preparo do solo (escarificador + grade niveladora, grade pesada + grade niveladora e plantio direto), inoculação ou não de sementes com estirpes de Rhizobium tropici (presença e ausência) e aplicação de N em cobertura aplicadas por ocasião da fase V4-5 (0, 60, 120 e 180 kg ha-1 ), com quatro repetições. Concluiu-se que o preparo do solo, com grade pesada, escarificador ou plantio direto e o uso de inoculação de sementes com Rhizobium tropici não alteram a produtividade de grãos da cultura e, a adubação nitrogenada em cobertura proporciona incremento na produtividade de grãos superior a 17% na dose de 180 kg de N ha-1 em relação ao tratamento testemunha. ABSTRACT Common bean is a demanding plant in nutrients, mainly in relation to nitrogen. The adoption of a management system that improves the soil conditions, associated to the appropriate nitrogen supply can be very important to increase the plant efficiency in the use of the available resources. This study aimed to evaluate different combinations of soil management, seed inoculation and nitrogen doses in the growth and yield of irrigated common bean plant in winter period. The experiment was conducted in Selvíria county (MS) in years of 2006 and 2007. A randomized completely blocks design in a factorial scheme 3 x 2 x 4, constituted by three soil management (chisel ploughing + leveling disk, heavy disk + leveling disk, and no till), seed inoculation with Rhizobium tropici ( with or without inoculation) and nitrogen doses at sidedressing on stage V4-5 (zero, 60, 120 and 180 kg ha-1), with four repetitions, was used. The soil management with chisel ploughing, heavy disk, or no till, and the use of seed inoculation with Rhizobium tropici does not interfere in the irrigated common bean yield; the nitrogen fertilization at sidedressing provides increment above 17% at dose of 180 kg ha-1 of nitrogen in relation to control.

Aims: This study aimed to evaluate the influence of nitrogen fertilization and inoculation of seeds with Rhizobium tropici on the agronomic performance of common bean (Phaseolus vulgaris L.). Study Design: The experimental design consisted of a randomized block in a 4x2 factorial layout, with 4 replicates, the first factor referring to inoculant doses (0, 50, 100 and 200 mL for each 25 kg of seed), while the second refers to nitrogen fertilization (0 and 40 kg ha of N). Place and Duration of Study: The study was conducted to the field in a no-till system area, in the southwestern region of Paraná, Brazil. The soil is classified as a Purple Latosol, with a clayey texture. Methodology: The adopted spacing was 0.45 m between rows, and the seeding density used was 12 seeds per furrow meter. The inoculants NITRO 1000 Rhizobium tropici SEMIA 4077 and SEMIA 4088 were applied, varied according to the treatments. The cultivar used was IPR – Tangará. Results: As for grain yield, it was observed that nitrogen fertilization did not contribute to the increase in grain yield, and higher productivity was obtained in the absence of N. This was probably due to the high content of organic matter present in the soil. Conclusion: Nitrogen fertilization at sowing and seed inoculation with Rhizobium tropici did not influence the plant population and the 1000-grain mass. In the absence of nitrogen fertilization at sowing, pods with a longer length and higher grain yield were obtained. Inoculation of the seeds with Rhizobium tropici exerts a positive influence on plant height, number of nodes of the main stem, number of pods per plant, and number of beans per pod, the dose recommended by the manufacturer (100 mL) being efficient, with the possibility of applying a dose of 50 mL, to satisfactory results.

Liquid Fertilization

The common bean production system is majorly based on the use of granular fertilizers to provide nutrients for the crop. Studies on the use of liquid fertilization at an appropriated depth and, seed inoculation with Rhizobium tropici can provide significant increases in the grain yield of the common bean. The objective of this study was to determine the growth and productivity of common bean as affected by N-P formulations, application depths and the inoculation with R. tropici. Field experiments were carried out in 2015 and 2016 cropping years using a complete block design, in a 2x2x2 factorial arrangement, with four replicates. The treatments involved the combination of N-P formulation (granular and liquid), two application depths of the N-P formulation (6 and 12 cm) and with or without rhizobia inoculant. The plant density (PD), number of pods (NP), number of grains (NG), mass of 100 grains (M100) and grain yield (GY) were determined. The granular and liquid N-P formulations provided similar results for PD, NP, NG, and GY of common bean. Similarly, the application depth of the N-P formulations did not affect GY. Inoculation of the seed with R. tropici stimulated NP and NG, increasing GY. Growth and productivity parameters were equally affected by the type of formulation and application depth; however, GY was greater with rhizobial inoculant. Thus, the liquid N-P formulation, applied at 6 cm depth, associated with rhizobial inoculant can improve the crop management providing better control of application uniformity, minimal soil mobilization, less fuel consumption, and increased grain yield.

The Impact

Strategic tillage describes the occasional use of tillage in an otherwise no-till system. The practice can provide a pragmatic solution to emerging agronomic issues in no-till systems but raises concerns about prolonged or irreversible soil damage. We investigated the impact of a single tillage event at a long-term no-till experiment under treatments with retained or annually autumn-burned crop residues. One half of each residue-treatment plot received a single pass of a rotary hoe (ST) 4 weeks before sowing in 2011, the first year of the experiment; the other half of each plot remained unchanged (NT). Soil physical, chemical and biological fertility in the surface layers (0–20 cm), as well as crop growth and yield were monitored for 5 years (2011–15). Following the ST treatment, soil bulk density and strength were initially reduced to the depth of cultivation (~15 cm) irrespective of residue treatment. Water-stable macroaggregates in the surface 0–5 cm were also reduced but recovered to pre-tillage levels within 1–2 years after ST treatment. Soil pH, total carbon (C), total nitrogen (N), and fine-fraction C and N were all initially stratified in the surface layer (0–5 cm) of the NT treatment but were redistributed more evenly throughout the 0–10 cm layer of the ST treatment and remained so throughout the 5-year period. With ST, there was an initial loss in total C stocks in the 0–10 cm layer of 2.2 t/ha, which recovered within 2 years; however, total C stocks remained lower in plots with stubble retained than with stubble burnt after 5 years. Soil Colwell P levels were not stratified and not influenced by tillage treatment, presumably because of the annual additions in the starter fertiliser at sowing. ST had no impact on crop establishment or grain yield in any year but increased the early biomass of wheat at Z30 compared with NT in the first 2 years. Annual stubble retention reduced the early growth of crops in all years, and yield of wheat in the first 3 years, consistent with long-term effects of retained stubble at the site, but there was no interaction between stubble retention and tillage treatments on soil conditions or crop growth. Crop yields of long-term, annually cultivated treatments were also similar to those of ST and NT treatments during the 5 years of the experiment. Overall, the minor short-term negative impacts on soil physical conditions, the persistent and arguably beneficial effects on soil chemistry and biology, and absence of impacts on crop production suggest that strategic tillage can be a valuable agronomic tool in sustainable production in this region.

The Impact

To date, few attempts have been made to assess the impact of Rhizobium inoculation on N2 fixation and plant yield in soilless cultivations of common bean. In the present study, common bean (P. vulgaris L.) grown on an inert medium (pumice) was inoculated with either Rhizobium tropici CIAT899 or a commercial product containing a mix of N2-fixing bacteria, specifically rhizobia, and Azotobacter sp. The plants treated with both inoculants were supplied with nitrogen (N)-free (0% N) nutrient solution (NS) throughout the cropping period. A third treatment with non-inoculated plants, which were supplied with a standard (100% N) NS was applied as a control. Inoculation with R. tropici significantly increased the total number of root nodules (80 nodules per plant on average) in comparison with the other two treatments (nine nodules per plant on average). The supply of N-free NS restricted markedly both total plant biomass and pod yield, whereas the inoculation with R. tropici mitigated this effect. The aboveground tissues of plants fed with N-free NS contained appreciably less N than those fed with standard solution when they were inoculated with the commercial inoculant (1.7 vs. 29 mg·g−1 dry weight, respectively). The shoot total N concentration 45, 65, and 90 days after transplanting (32, 31, and 29 mg·g−1 dry weight, respectively) was not reduced by the supply of N-free NS when the plants were inoculated with R. tropici. This finding indicates that, at least from the first sampling date onward, the tissue N level was not a limiting factor for growth and yield in plants inoculated with R. tropici. The supply of N-free NS restricted appreciably the potassium (K), magnesium (Mg), and zinc (Zn) levels in the aboveground plant biomass, regardless of inoculation treatment. The impaired growth and yield in plants fed with N-free NS and inoculated with R. tropici is ascribed to both a N shortage at early growth stages and a reduced K+ uptake aimed at electrochemically balancing the anion-to-cation uptake ratio under conditions of no external NO3– supply.

ABSTRACT Knowledge of the interactions between soil physical properties and yield performance in agricultural crops is very important for the adoption of appropriate management practices. This study aimed to evaluate the linear and spatial correlations between some soil physical attributes, straw production in the palisade grass (Urochloa brizantha), and grain yield of winter common bean in succession to the grass under an irrigated no-till system in an Oxisol Haplorthox in the Cerrado lowlands region of Brazil. The plant attributes determined were dry matter yield of U. brizantha (DMY), and grain yield (GY) and final plant population (PP) of winter common bean. The soil physical attributes, evaluated at 0.0-0.10 m and 0.10-0.20 m, were soil bulk density (BD), macroporosity (MA), microporosity (MI), total porosity (TP), penetration resistance (PR), gravimetric water content (GW), and volumetric water content (VW). A geostatistical grid with 124 sampling points was installed to collect the soil and plant data in an area of 4000 m2. The remaining straw amount of palisade grass exhibited an inverse linear correlation with bean yield and bean plant population when the bean was cultivated in succession. However, no spatial correlations were observed among the attributes. The common bean yield had a direct linear correlation with gravimetric water content in the 0.10-0.20 m soil layer. From a spatial point of view, winter bean yield showed a strong dependence on the distribution of the volumetric water content in the 0-0.10 m soil layer.

Soil salinity and sodicity are among the main problems for optimum crop production in areas where rainfall is not enough for leaching of salts out of the rooting zone. Application of organic and Ca-based amendments have the potential to increase crop yield and productivity under saline–alkaline soil environments. Based on this hypothesis, the present study was conducted to evaluate the potential of compost, Ca-based fertilizer industry waste (Ca-FW), and Ca-fortified compost (Ca-FC) to increase growth and yield of maize under saline–sodic soil conditions. Saline–sodic soil conditions with electrical conductivity (EC) levels (1.6, 5, and 10 dS m−1) and sodium adsorption ratio (SAR) = 15, were developed by spiking soil with a solution containing NaCl, Na2SO4, MgSO4, and CaCl2. Results showed that soil salinity and sodicity significantly reduced plant growth, yield, physiological, and nutrient uptake parameters. However, the application of Ca-FC caused a remarkable increase in the studied parameters of maize at EC levels of 1.6, 5, and 10 dS m−1 as compared to the control. In addition, Ca-FC caused the maximum decrease in Na+/K+ ratio in shoot up to 85.1%, 71.79%, and 70.37% at EC levels of 1.6, 5, and 10 dS m−1, respectively as compared to the control treatment. Moreover, nutrient uptake (NPK) was also significantly increased with the application of Ca-FC under normal as well as saline–sodic soil conditions. It is thus inferred that the application of Ca-FC could be an effective amendment to enhance growth, yield, physiology, and nutrient uptake in maize under saline–sodic soil conditions constituting the novelty of this work.

Enrichment of staple food with zinc (Zn) along with solubilizing bacteria is a sustainable and practical approach to overcome Zn malnutrition in human beings by improving plant nutrition, nutrient use efficiency, and productivity. Common bean (Phaseolus vulgaris L.) is one of a staple food of global population and has a prospective role in agronomic Zn biofortification. In this context, we evaluated the effect of diazotrophic bacterial co-inoculations (No inoculation, Rhizobium tropici, R. tropici + Azospirillum brasilense, R. tropici + Bacillus subtilis, R. tropici + Pseudomonas fluorescens, R. tropici + A. brasilense + B. subtilis, and R. tropici + A. brasilense + P. fluorescens) in association with soil Zn application (without and with 8 kg Zn ha−1) on Zn nutrition, growth, yield, and Zn use efficiencies in common bean in the 2019 and 2020 crop seasons. Soil Zn application in combination with R. tropici + B. subtilis improved Zn accumulation in shoot and grains with greater shoot dry matter, grain yield, and estimated Zn intake. Zinc use efficiency, recovery, and utilization were also increased with co-inoculation of R. tropici + B. subtilis, whereas agro-physiological efficiency was increased with triple co-inoculation of R. tropici + A. brasilense + P. fluorescens. Therefore, co-inoculation of R. tropici + B. subtilis in association with Zn application is recommended for biofortification and higher Zn use efficiencies in common bean in the tropical savannah of Brazil.

Given the high costs of agricultural production, especially due to the price of fertilisers, particularly nitrogen, the use of inoculants to supply nitrogen to soybean crops is a widely recommended practice. The objective of this study was to evaluate the feasibility of applying inoculants through seed and planting furrow in soil previously cultivated with soybean and Brazilian native “cerrado” biome soil under greenhouse conditions. Seven treatments were tested: 1) inoculation via seed (inoculant + fungicide + micronutrient), 2) treatment via seed (fungicide + micronutrient), 3) control (only seed), 4) inoculation via furrow-dose 1 (recommended dose), 5) inoculation via furrow-dose 2 (twice the recommended dose), 6) inoculation via furrow-dose 3 (three times the recommended dose) and 7) inoculation via furrow-dose 1 + seed inoculation. We evaluated plant height, fresh and dry matter weight of the aerial part and nodules, number of total, viable and non-viable nodules, number of pods per plant and grain yield. Inoculation was more effective when used in cerrado soil, but soybean performance in treatments without inoculation was higher in previously cultivated soil. Application through furrow proved to be a viable practice due to the similarity of the results obtained with the traditional application by seed.
