SummaryMaize (Zea mays L.) and common bean (Phaseolus vulgaris L.) were each sown at four plant densities, including zero, in a bivariate factorial design at Kiboko Rangeland Research Station, Kenya during the long and short rains of 1990. The design gave nine intercrops with different proportions of maize and beans, and six sole crops, three of maize and three of beans. Seed yields in both the sole crops were not significantly affected by plant density, so the mean yield was used to calculate the Land Equivalent Ratio (LER), which averaged 1·09 in the long rains but only 0·87 in the short rains. These low values were apparently due to the fact that beans failed to nodulate and fix nitrogen in the study area. The difference in LER between seasons was probably caused by differences in the amount and distribution of rain in relation to crop growth. Maize was more competitive than bean, each maize plant being equivalent to between 0·7 and 3·4 bean plants depending upon the treatment and the season.

Summary. Legumes have become common rotation crops in cotton cropping systems in northern New South Wales. Levels of nitrogen fixation and yield achieved on-farm were measured in commercial faba beans and other winter and summer legume crops sown after cotton over 3 years to assess the relative inputs of fixed nitrogen (N) into this system. Faba bean crops fixed up to 350 kg N/ha, removed up to 160 kg N/ha in harvested grain and contributed up to 270 kg fixed N/ha to soil N after harvest. Grain yields, N2 fixation and dry matter production were reduced in late-sown crops and those water-stressed during pod-filling, but most faba bean crops fixed almost 3 times as much N as was removed in grain. Below-ground legume N, determined with 15N shoot feeding techniques, accounted for 40% of the total crop N at peak biomass, or about 100 kg N/ha for the average faba bean crops. Residual fixed N after harvest was predicted from crop dry matter and grain yield, and this could be used to assess the contribution to soil N from faba beans. Amounts of nitrogen fixed by other legume crops ranged from 20 kg N/ha for adzuki bean and droughted lablab to more than 450 kg N/ha by irrigated soybean. Soybean, peanut and Dolichos lablab contributed more fixed N to the soil than adzuki bean, mung bean or pigeon pea under irrigated conditions. Winter crops including field peas, lentils and lupins and green-manured pasture species fixed up to 240 kg N/ha.

Nitrogen (N), a mineral element required in greater quantity by plants, has a low efficiency use in agriculture, resulting in economic and environmental problems. N enhanced efficiency fertilizers use is one of the strategies to increase N fertilization efficiency. Polymer urea coating has been used to produce enhanced efficiency fertilizers. However, there are a lot of polymers for this type of coating, which may lead to divergence of results. Validation of this technology to guarantee its viability in agriculture is necessary. This study aimed to evaluate rice, common bean and corn morphological characteristics, foliar N contents and yields and N fertilization efficiency in response to N rates and sources. Field experiments were carried out on these crops, comparing N fertilizers performance. Each experiment was formed by a factorial design comparing N sources (urea and Policote coated urea) and rates, besides Control. N fertilization influenced rice, common bean and corn morphological characteristics, foliar N contents, yields and N fertilization efficiency. Increasing N rates increased rice, common bean and corn morphological characteristics and yields. Policote coated urea showed higher agronomic efficiency of nitrogen fertilization and higher yields than urea in rice, common beans and corn crops.

Two research fields were conducted on a Haplohumox from 1998 and to 2005. The study aimed to evaluate the strategies for starter fertilizer application on corn, soybean and common bean yield as well as the accumulation of earlier dry matter for corn in a no-tillage crop rotation system in south of Brazil. There was no increase in the yield of soybean with phosphorus and potassium application for at least seven seasons, while corn and common bean showed increased yields with phosphorus, potassium and nitrogen application. For soybean, corn and common beans in no-tillage systems with high levels of phosphorus and medium of potassium, the starter fertilizer can be applied in any of the methods evaluated and in any of the period considered. The presence or absence of potassium in the furrow, phosphorus sources and row preparation components provided similar yields to corn, soybean and common bean.

The use of adequate management practices and high nitrogen fertilizer rates have contributed to increase the common bean grain yield, however, the application of nitrogen fertilizer at sowing still requires evaluations for irrigated crops in the Brazilian Cerrado biome region. Thus, the objective of this work was to evaluate the effect of application of different rates of controlled-release nitrogen fertilizer—dimethylpyrazole phosphate (DMPP)—at sowing and as top-dressing on agronomic performance and leaf area index of irrigated common bean crops grown in the Brazilian Cerrado biome region. A randomized block design in a 4×3 factorial arrangement with four replications was used. The treatments consisted of four nitrogen rates (0, 60, 120, and 180 kg ha-1) and three application forms (100% at sowing, 100% as top-dressing, and 50% at sowing + 50% as top-dressing). Irrigation was managed with class A tanks and two-day intervals. The nitrogen applied at the different stages of the crop did not affect the production components of the common bean plants. The highest grain yields were found with the nitrogen rates of 180 kg ha-1 in 2015 (1,756.37 kg ha-1), and 123.98 kg ha-1 in 2016 (1,799.63 kg ha-1).

Beans are one of the main foods consumed in Brazil. It is considered an essential ingredient in the basic diet of Brazilians. As a management practice, aiming to supply N and increase crop productivity, producers have used the association of seed inoculation with nitrogen fertilization. Thus, the objective of this study is to evaluate the effects of split nitrogen fertilization and seed inoculation on common bean productivity. The experiment was carried out in completely randomized blocks and a 2x2x3 factorial design with four replications. The first factor was seed inoculation (presence or absence) with peat inoculant containing the strains SEMIA 4077 and SEMIA 4080 from R. tropici and the strain SEMIA 4088 from R. freirei. The second factor was the parceling of nitrogen cover fertilization (80+40 and 60+60 kg ha-1 of N at 20 and 40 days after emergence (DAE)). The third factor was time of assessment (50, 65 and 80 DAE). The inoculated bean showed a 5% higher leaf N content than non-inoculated ones. Transpiration and liquid photosynthesis rates were higher in inoculated plants and in those with 60+60 kg ha-1 of N. However, productivity was 13% higher in uninoculated beans regardless of nitrogen fertilization.

The contribution of plant residues to the soil is an essential requirement for the success of no-tillage systems, especially in areas with a tropical climate where the organic material decomposition rate is high. The type of straw present on the soil surface can influence the culture implanted subsequently, mainly with regard to the availability of nitrogen (N). The objective of this study was to investigate the effect of cultural remains of maize (exclusive or intercropped with cover crops) on the development and productivity of the common bean grown in succession and fertilized with different N doses. The experimental design was a randomized block arranged in a factorial scheme (5 × 4), with four replications. The treatments consisted of combinations of cultural remains of exclusive maize, maize + Crotalaria spectabilis, maize + Cajanus cajan, maize + Canavalia ensiformis, and maize + Urochloa ruziziensis cultivated previously and of four N rates (0, 40, 80, and 120 kg ha-1) applied to bean crops. The plots consisted of seven lines of 7.5 m length with 0.45 m spacing between the lines. The evaluated parameters were: dry matter of the plant cover, dry matter of the aerial part (beans), production components, weight of 100 grains, and grain yield. The intercropping of maize and cover crops promoted an increase in dry matter over the soil, compared to the exclusive maize crop. There was an increase in the dry matter of bean plants with the increase in N rates in the two years of cultivation; regarding productivity, there was an increment only in the first year of cultivation. The maize consortium with cover plants provided adequate soil cover, but did not influence the productivity of beans cultivated in succession in the two years of cultivation.

ABSTRACT The common bean requires high levels of nitrogen (N) to achieve high productivity, which can be supplied, at least partially, by the biological nitrogen fixation (BFN). Two field experiments were carried out in the winter season of 2015 aiming to evaluate the effects of different cover crops, desiccation times and the agronomic performance of the common bean inoculated with rhizobia. The experiments were assembled in a randomized block design with four replications, in a factorial split-plot arrangement with two additional treatments (5x4x2+2). The factors were composed of five cover crops, four desiccation times, two seed inoculation treatments and two additional controls (TN = 90 Kg N ha-1 and T0 = without N and without inoculation). The variables analyzed in the cover crops were dry mass (DM) and total nitrogen (Total-N). With the common bean, the chlorophyll content (CC), the number of nodules (NN), the nodule dry weight (NDW), the shoot dry weight (SDW), the root dry weight (RDW) and the grain yield (GY) were evaluated. The results showed that the agronomic performance of the common bean was not affected by the desiccation times of the cover crops, although the amount of Total-N accumulated by cover crops was influenced by sowing times. Inoculation of the common bean promoted an increase in the NN, NDW, CC and SDW. Higher GY of the common bean was achieved with its cropping after Brachiaria brizantha, Brachiaria ruziziensis, millet and fallow.

This study aimed to evaluate the effects of low and high topdressing doses of nitrogen (N) on the qualitative attributes of common beans (Phaseolus vulgaris L.) cultivars and indicate cultivars with better grain technological characteristics. The experimental design was randomized blocks in split plots, with four replicates. Plots comprised 16 common bean cultivars of the commercial grain ‘Carioca’, while subplots comprised two N doses: 20 and 120 kg ha-1 applied as topdressing. The following evaluations were carried out: sieve yield (SY), relative grain production on sieves (RGPS), crude protein content (PROT), final water volume absorbed (FVabs), time for maximum hydration (TMH), hydration ratio (HR), cooking time (CT) and resistance to cooking (RC). The results were subjected to analysis of variance by F test and means were grouped by the Scott-Knott test. Multivariate principal component analysis was used to identify processes. The grain quality of common bean is more dependent on the genotype studied than on agricultural management such as nitrogen fertilization. The increase in the N dose applied as topdressing increases the size of common bean grains and their protein content, but with little influence in grain hydration. FVabs and CT depend on the interaction between cultivar and N doses. CT had an inverse correlation with PROT, but it was little pronounced. The cultivars BRSMG Uai, IAC Alvorada, TAA Dama and TAA Bola Cheia have the best grain quality characteristics. Highlights: Cultivar interferes more in the common bean technological quality than nitrogen fertilization. Grains crude protein content had an inverse correlation with the cooking time. Nitrogen fertilization increases the grains size and crude protein content of common bean, but with little influence in grain hydration. The cultivars BRSMG Uai, IAC Alvorada, TAA Dama and TAA Bola Cheia have the best grain quality characteristics.

In field conditions, the more usual application of cytokinins is based mainly on seed treatment and foliar spraying. Nowadays, seed priming with plant growth regulators is a successful agricultural practice due to its easy application in annual crops, resulting in a higher vigor and production. In order to evaluate the effect of the treatment of common bean seeds with N6-benzyladenine (6-BA), in the morphophysiology and crop yield, an experiment was carried out in a greenhouse, in a completely randomized design with four replicates and five doses of 6-BA (0, 0.0375, 0.075, 0.1125 and 0.15 g kg-1 of seed). The growth regulator was applied to the seeds in order to cover their entire surface. At 30 days after emergence, the physiological parameters were increased as a function of the doses of 6-BA. On the other hand, at 30 and 45 days after emergence of the crop, there was a drastic reduction in nodulation with increased 6-BA doses, which resulted in the lower accumulation of leaf nitrogen, pod number, and common bean yield. The ranging doses till 0.15 g kg-1 of seed of the cytokinin 6-BA are not recommended in seed priming of common beans. However, the effective recommendation of cytokinin as a seed priming is still not determined, and studies about products and doses must be improved before recommendation.

A implantação da cultura do feijão no sistema de plantio direto vem crescendo em todo território nacional, entretanto, o plantio direto exige uma adubação nitrogenada diferenciada, tornando-se necessário buscar mais informações a esse respeito. Nesse contexto, o trabalho foi desenvolvido em um LATOSSOLO VERMELHO Distrófico (LVd), em Selvíria - MS, com o objetivo de verificar o efeito da aplicação de diferentes níveis de nitrogênio em cobertura (0, 30, 60, 90, 120 e 150 kg ha-1), na cultura do feijão de inverno em sistema de plantio direto, após diferentes coberturas vegetais (milho, milheto, arroz, mucuna-preta, soja, Crotalaria juncea e milho + mucuna-preta). O delineamento experimental foi o de blocos casualizados em um esquema de parcelas subdivididas, com 4 repetições. Foram avaliadas: cobertura vegetal da cultura anterior, matéria seca das plantas, população de plantas, componentes produtivos (número de vagens e de grãos por planta, número de grãos por vagem e massa de 100 grãos), N total na parte aérea e nos grãos e, produtividade de grãos. Concluiu-se que A Crotalaria juncea e mucuna-preta proporcionaram a melhor cobertura do solo no período avaliado, com a Crotalaria juncea apresentando a maior quantidade de matéria seca (15.201 kg ha-1), o que é um fator importante no sistema de plantio direto; as diferentes coberturas vegetais não influenciaram significativamente a produtividade do feijoeiro cultivado em sucessão; a aplicação de doses crescentes de nitrogênio em cobertura aumentou a produtividade do feijoeiro, entretanto mesmo onde não houve aplicação do fertilizante a produtividade foi superior a 2000 kg ha-1, de forma que uma análise econômica passa a ser um fator importante para a tomada de decisão.

The used design consisted of randomized blocks in a split-plot scheme and four replications. Crop residues, number of days to the bloom, dry matter weight, stand, number of pod and seeds per plant, number of seeds per pod, weight of 100 seeds, N in leaves and seeds and yield were evaluated. The results showed that: the Crotalaria juncea and black velvet bean provided the most crop residue, and the Crotalaria juncea with a highest dry matter weight (15.201 kg ha-1), it is a important factor on the no tillage system; there was not crop residues influence under common bean yield; the sidedressing nitrogen application increased the production, however where there was not N application the yield were higher to 2000 kg ha-1, with the economic analysis is the important to decision.

The association between root-nodulating bacteria and leguminous plants is advantageous due to their ability to alter atmospheric nitrogen into a useful form in a process known as biological nitrogen fixation (BNF). Research has shown that BNF is the most efficient way to supply the large amounts of nitrogen needed by plants to produce high-yielding crops. As a result, there have been numerous studies into the diversity and identity of the associated nitrogen-fixing bacterial symbionts. Recent advances in molecular microbiology together with the isolation of rhizobia from previously uninvestigated legumes have led to major revisions of rhizobial taxonomy, most notably the inclusion of bacteria from the ß-Proteobacteria in the genera Burkholderia and Ralstonia. In this study, the diversity of root nodule bacteria associated with Phaseolus coccineus and Phaseolus vulgaris species in South Africa was investigated. A selection of rhizobial isolates were characterised by SDS-PAGE of whole cell proteins and rep-PCR DNA fingerprint analyses. These results were supplemented by partial 16S rDNA sequencing of a select number of isolates to confirm their identity. Where isolates displayed unexpected genus associations, partial nodA sequencing was performed to determine whether these were incidental contaminants or true nodulators. Based on 16S rDNA sequence analysis, the majority of isolates investigated were fast-growers belonging to the genus Rhizobium. A few isolates showed close relationship to species of the ß-Proteobacteria genus, Burkholderia. Both the SDS-PAGE analyses and the combined rep-PCR analyses were able to resolve isolates down to strain level, but the comparison of the SDS-PAGE and 16S rDNA sequencing data confirmed that bacterial discrimination using SDS-PAGE is not useful at the genus level and higher, as isolates showing affinity to Burkholderia were mingled with isolates showing similarity to Rhizobium. These isolates were separate from the Rhizobium isolates in the combined rep-PCR dendrogram. While there were discrepancies between results obtained from SDS-PAGE and rep-PCR analyses, results from the combined rep-PCR analysis correlated with many of the results obtained in the SDS-PAGE analysis. Both geographic location and host plant species appear to have affected the grouping of isolates. Many clusters consisted of isolates from the same location or the same host plant species in both the SDS-PAGE dendrogram as well as the combined rep-PCR dendrogram. The nodA sequencing demonstrated that the majority of isolates tested contain the nodA gene indicating that they are capable of nodulation. There was a large strain diversity observed for the isolates of this study and a number of the root-nodulating bacteria of the Phaseolus spp. appear to constitute several novel nodulating genotypes.Dissertation (MSc (Microbiology))--University of Pretoria, 2007.

The ecological significance of leguminous crops grown in modern intensive crop rotation in Ukraine is considered. In particular, the sown areas of common leguminous crops in Ukraine and the level of their productivity have been analyzed. A comparison is made with the acreage of common field crops in Ukraine. The volume of accumulation of by-products in the form of their straw and stubble is calculated. A comparison is made for these indicators with the most widespread grain crops grown in Ukraine. The data on the content of the main nutrients in the by-products of leguminous crops – nitrogen, phosphorus, potassium are given. On the basis of these indicators, a calculation was made of the accumulation of the main nutrients in the soil, which can come with by-products of leguminous crops at their average yield. We also compared the obtained indicators with the input of nitrogen, phosphorus and potassium into the soil with by-products of the most common grain crops. Calculated symbiotic nitrogen fixation by leguminous crops. Based on this, a conclusion was made about the most effective leguminous crops, the cultivation of which in the modern intensive crop rotation of Ukraine will more contribute to the stabilization of the agroecological state of the soil. It is proved that an increase in the areas of leguminous crops in the intensive crop rotation of Ukraine will have a positive effect on the agroecological state of the soil. In particular, growing beans allows you to get the highest mass of by-products, which can be buried in the soil – 3.5 t/ha. Also, the by-products of beans provide the input into the soil of all mineral phosphorus – 12.6 kg/ha of all leguminous crops, as well as potassium – 16.5 kg/ha. By-products allow to accumulate more mineral nitrogen in the soil with by-products – 38.4 kg/ha. Also, soybeans are characterized by a high symbiotic nitrogen-fixing ability among all leguminous crops – 120 kg/ha.
