Filling Stage

An experiment was carried out with common bean (Phaseolus vulgaris, L.) in a Red Yellow Latossol, sandy phase, in order to study the influence of foliar spraying of the Hanway nutrient solution (NPKS) at grain filling stage on: 1) grain yield; 2) the uptake of fertilizer and soil nitrogen by this crop through the root system and 3) the efficiency of utilization of the nitrogen in the foliar spray solution by the grain. The results of this experiment showed that the foliar application of the Hanway solution with ammonium nitrate at the pod filling period caused severe leaf burn and grain yield was inferior to that of the plants which received a soil application of this fertilizer at the same stage. These facts can be attributed to the presence of ammonium nitrate in the concentration used. The composition of final spray was: 114,28 Kg NH4NO3 + 43,11 Kg potassium poliphosphate + 12,44 Kg potassium sulphate per 500 litres. The uptake of nitrogen fertilizer through the root system and the efficiency of its utilization was greater than that through the leaves.

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.

Sole Cropping

Breeding of common bean (Phaseolus vulgaris L.) for intercropping with maize (Zea mays L.) is usually done in bean sole crop nurseries. However, bean cultivar evaluations have identified significant cultivar × cropping system interactions. The objective of this study was to determine whether intercrop and sole cropping systems have different effects on phenotypic and genetic variance components of bean populations. Unselected F2 and F3 populations of 16 crosses of common bean were evaluated in the two cropping systems at Elora and Woodstock, Ontario, Canada, in 1993 and 1994. Significant population × cropping system interaction was found for grain yield and pods per plant. Genetic correlations between cropping systems were lowest for grain yield and pods per plant and highest for seed weight and seeds per pod. There were few differences between cropping systems for genetic variances. Genotype × location variance was higher in intercrop than in sole crop. Broad-sense heritabilities and narrow-sense heritabilities for most traits were comparable between cropping systems. The exception was pods per plant, which showed greater heritability in sole crop. Realized heritability of grain yield was greater in intercrop. We conclude that single plant selection as done with the pedigree system of breeding should be effective in intercrop. Key words: Genetic variances, heritability, intercrop, Phaseolus vulgaris

Rhizobium Tropici

O uso de rizobactérias promotoras de crescimento de planta (RPCP) associado a inoculação de rizóbio pode otimizar a fixação biológica de nitrogênio (FBN), diminuindo o uso de fertilizantes nitrogenados e aumentando o crescimento da planta e o rendimento da cultura do feijão. Um estudo foi conduzido para investigar a eficácia da coinoculação de Rhizobium tropici e Azospirillum brasilense e da adubação nitrogenada em cobertura na nodulação, no crescimento e no rendimento de grãos do feijoeiro (Phaseolus vulgaris L.) cultivado em solo arenoso da região do Cerrado brasileiro, durante duas safras de produção (“safra das águas” e “safra da seca”). O delineamento experimental foi o de blocos casualizados em esquema de parcelas subdivididas, com quatro repetições. As parcelas constituíram de quatro tratamento de inoculação das sementes: controle (não inoculado); inoculação com Rhizobium tropici; inoculação com Azospirillum brasilense; e, coinoculação com R. tropici e A. brasilense; e as subparcelas por cinco doses de N em cobertura (0, 30, 60, 90 e 120 kg ha-1). A inoculação das sementes com Rhizobium tropici isoladamente ou combinado com Azospirillum brasilense melhorou a nodulação das raízes e o rendimento de grãos do feijoeiro comum quando a cultura foi cultivada durante a “safra da seca”. Portanto, a resposta positiva da inoculação das sementes com Rhizobium e Azospirillum no rendimento de grãos depende das condições ambientais durante a safra de produção, especialmente da menor taxa de precipitação pluvial por estimular a nodulação das raízes. A inoculação com A. brasilense isoladamente não foi uma prática agronômica eficiente para ser utilizada no cultivo do feijoeiro nas condições brasileiras, resultando em rendimento de grãos equivalente às plantas do tratamento não inoculado nas duas safras de produção. O aumento das doses de adubação nitrogenada em cobertura inibe a formação e o crescimento dos nódulos radiculares do feijoeiro. A dose de adubação nitrogenada em cobertura ótima para o cultivo do feijoeiro em solos arenosos da região do Cerrado brasileiro pode variar entre 80 e 90 kg ha-1 de N.
