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.

Over two cropping seasons, 2017/18 and 2018/19, an experimental trial was conducted in a typical cereal-growing environment of the Calabrian hills (southern Italy) to study seeding rate (D) and nitrogen fertilization (N) effects on two barley F1 hybrids (Zoo and Jallon) compared to those of a traditional variety (Lutece), assessing the bio-agronomic response. Barley hybrids, gradually introduced into the principal European countries starting in 2010 as winter forage, currently represent a significant part of the EU internal market. Productive performance was evaluated as grain yield for feed and total biomass for silage and/or biogas production. Research results pointed out the greater performance of barley hybrids compared to conventional varieties in terms of both grain and biomass production. On average, barley hybrids vigour mainly manifested itself through a high tillering and a greater number of ears m−2 compared to those of the conventional variety (+24 and +23%, respectively). Furthermore, barley hybrids were characterized by a greater 1000-kernel weight and hectolitre weight than those of the Lutece variety (conventional variety). A significant increase in grain production was observed, increasing density from D150 to D225 rates (+35% and +33%, respectively) which was followed by a decrease in production shifting from D225 to D300 doses. A significant increase in biomass production was as well highlighted for the two hybrids, shifting from D150 to D225 rates (+26% and +27%, respectively). The applied nitrogen dose highlighted a different behaviour between the hybrids and the conventional variety; in particular, the lowest nitrogen dose (N80) negatively influenced the Lutece variety both in terms of grain and biomass production (−9% and −16%, respectively) while the hybrids showed the best agronomic response even at the lowest dose. On average, with the N80 dose, grain yield of Zoo and Jallon was greater than 20% and 16%, while with the N120 dose grain yield was 9% and 7%, respectively. A similar behaviour was found for biomass yield. It should therefore be emphasized that barley hybrids possess high yielding capacities and that such higher grain production can be achieved in a Mediterranean environment by using a lower seed rate (approximately −25%) and a reduced nitrogen dose (approximately −33%) compared with those commonly applied to conventional varieties.

The objective of this work was to evaluate the efficiency of nitrogen fixing inoculum associated with Co + Mo leaf spray on the common bean grain yield and grain nutrients, cv. FT Nobre. Three dosages of the inoculant (0, 200 and 400 g/50 kg seeds), combined with four Co + Mo leaf spray levels (T0=0,0; T1=4.9,49; T2=7.3,73; and T3=9.7,97 g ha-1 of Co and Mo, respectively) were tested. The grain yield with the use of the inoculant (400 g / 5O kg seed-1) associated with the higher level of Co+Mo (T2 and T3) was very similar to the mineral nitrogen condition fertilizer recommended for the bean (70 kg ha-1 of N). With the increased inoculant dosage, an increase of the protein content and of P and Mg in the grain was also observed. The results indicated that the mineral nitrogen source could be replaced by inoculation of the seeds with Rhizobium tropici combined with Co + Mo leaf spray.

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.

Maize inoculation with bacteria of the genus Azospirillum can reduce the consumption of nitrogen fertilizers to obtain maximum grain yield. In this context, the aim was to evaluate the effect of inoculation with Azospirillum brasilense associated with nitrogen fertilization on the maize agronomic performance. A randomized block design was used in a split-plot scheme with four replicates. Four inoculation managements with Azospirillum brasilense (T0 - control without inoculation; TC2 - seed box inoculation, 200x108 viable cells ha-1; TC3 - seed box inoculation, 400x108 viable cells ha-1; TS1 - previous inoculation of the seeds, 600x108 viable cells ha-1) associated with four top-dressing N doses (0, 60, 120 and 180 kg ha-1), applied at maize stage V6 by urea. Inoculation with Azospirillum brasilense associated with top-dressing nitrogen fertilization increases the number of grain rows per ear, number of grains per row, number of grains per ear and grain yield of maize, mainly due to its positive effects on plant nutrition. Managements with seed box inoculation with 400x108 viable cells per ha (TC3) and inoculation in seed pre-treatment (TS1) are the most recommended for maize.

RESUMO – O sistema plantio direto é uma estratégia sustentável de produção que preconiza a manutenção da cobertura vegetal como prática conservacionista do solo. Objetivou-se avaliar o efeito de plantas de cobertura sobre atributos fisiológicos e agronômicos do milho na região sudoeste da Amazônia. Foram avaliadas 15 estratégias de sucessões de culturas com o milho e a influência sobre o rendimento de biomassa, de grãos, altura de plantas e inserção da espiga, índice de espiga, massa de 100 grãos, teor foliar de nitrogênio e clorofilas total, a e b em plantas de milho. Observou-se efeito das plantas de cobertura sobre o rendimento de grãos, de biomassa fresca e seca, na massa de grãos e nos teores de clorofila. Os efeitos sobre os teores de clorofila foram mais pronunciados na clorofila b e nos estádios fenológicos finais da cultura. O feijão-de-porco promoveu as maiores produtividades de grãos (7.539,3 kg ha-1) e potencial de silagem (16,2 Mg ha-1 de biomassa seca). A adequada escolha das espécies que compõe um sistema de plantio direto é preponderante para o apropriado desempenho agronômico do milho na região sudoeste da Amazônia.Palavras-chave: Zea mays, intensificação ecológica, sustentabilidade, integração lavoura-pecuária, plantio direto.CROPPING SYSTEMS ON THE PERFORMANCE OF CORN PLANTS IN THE SOUTHWESTERN AMAZONABSTRACT- A sustainable strategy for agricultural systems is the use of cover crops in no-tillage systems, as a conservationist soil practice. This paper aimed to evaluate the short-term effects of different cover crops on some physiological and agronomic attributes of corn crop in the Southwestern Amazon region. The effects of 15 cover plants on the biomass and grains yield, plant height, ear insertion height, ear index, mass of 100 grains, leaf nitrogen content and a, b and total chlorophyll levels of corn plants were evaluated. A randomized complete block design was used with four replications. Grain yield, fresh and dry biomass yield, mass of 100 grains and chlorophyll content were affected by some cover crops. Jack bean promoted the highest grain yield (7,539.3 kg ha-1) and biomass yield (16.2 Mg ha-1 dry matter) among the options assessed. Cover crops provided different levels of total, a and b chlorophyll levels, on the corn plants. Some cover crops presented the potential to improve the agronomic performance of the succeeding corn crop in the Southwestern Amazon region. The proper agronomic performance of corn in a no-till system depends on the adequate choice of cover plants to compose the system.Keywords: Zea mays, ecological intensification, sustainability, crop-livestock system, no-till.

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.

Snap Beans

Snap beans (Phaseolus vulgaris L.) belong to the same species as common beans and require similar management practices. Studies aimed at nitrogen fertilization in pod beans are scarce, but necessary, considering the demand from farmers for greater productivity of these beans. The objective of this study was to evaluate the effects of nitrogen fertilization in various doses and times of application on the snap beans production. The experimental design was completely randomized in a factorial scheme (2×7) + 1, represented by two doses of nitrogen (30 and 60 kg ha-1) and seven fertilization strategies (100% of the dose provided at sowing or phenological stages V3, V4, or R6; split, with 50% at sowing and 50% at V3, 50% at sowing and 50% at V4, or 50% at sowing and 50% at R6), plus a control (no added N). We analyzed stem length, stem basal diameter, number of trefoils, number and mass of commercially viable pods, and number and mass of total pods. Nitrogen fertilization with 30 kg ha-1 N divided 50% at sowing and 50% at V4 or 50% at sowing and 50% at R6 yielded larger and more numerous pods from plants with greater stem diameters.
