SummaryCompetitive and regulatory effects of defined inflorescences on the development of other inflorescences and subsequent yield performance of field beans (Vicia faba L.) were investigated. Genotypes differing greatly in yield performance (two inbred lines and the F1 hybrid produced from the two inbred lines) were used in both field and pot experiments. Yield was manipulated by the removal of defined inflorescences at various times and positions.In comparison with untreated control plants the removal of up to four inflorescences from basal, central or apical nodes caused a loss of yield potential of up to 65%. Nevertheless the final seed yield per plant was not reduced. This was because additional pods and seeds developed at remaining inflorescences. After the removal of inflorescences from either basal or apical regions of the plant significant overcompensation effects occurred. The effects were influenced by the growing conditions. The capacity for compensation existed at differing yielding levels regardless of different genotypes or growing conditions.The results are discussed with respect to the utilization of the initiated yield potential and to yield reliability.

SUMMARYEstimates of genotypic and phenotypic variances and covariances were determined for yield and yield components in ten field beans varieties grown at two locations over three seasons.Substantial amounts of genotypic variance were obtained for yield/plot, 1000-seed weight and number of pods/plant. Variability in number of seeds/pod and much of the variation in yield/plant was attributable to environmental effects and their interaction with the varieties. Seed yield/plot was closely and positively correlated with number of pods/plant and yield/plant, while it was closely and negatively correlated with 1000-seed weight.The implications of these correlations for selection are discussed.

SummarySelf-pollinating and cross-pollinating by hand samples of flowers in field bean crops usually gave an increased set of seed compared with control flowers left to be pollinated naturally. Hence, insect pollination of field bean crops is often inadequate. In large fields of more than 12 ha the seed yield was greater by plants near the edge than near the centre. Fewer pods were produced from nodes at the upper than the lower parts of a stem, and they contained fewer seeds which were of a smaller size.

SUMMARYEffects of inflorescence removal under different plant densities and degrees of shading on seed yield of field beans (Vicia faba L.) were investigated. Two indeterminate cultivars were used in field experiments for two seasons (1985 and 1986). The hierarchy within the generative storage system of field bean plants was manipulated by removal of inflorescences at various growth stages and nodes.Removal of the inflorescences of nodes 1–3 (counted from the base upwards) caused about 30% loss of seed yield potential compared with the control but compensatory increases in seed yield were found, differing with plant density and duration of shading. Under favourable growing conditions (no shading, 20 plants/m2), overcompensation occurred, giving a mean seed yield up to 40% more than in controls.Removal of all inflorescences above the ninth flowering node did not significantly reduce seed yield as plants completely compensated for the restriction on yield imposed.

Faba beans (Vicia faba L.), also known as fava beans, like other crops, are influenced by several factors: their genotype, environment, and management, as well as the interaction between these, have an important impact on seed yielding and seed quality traits. This study was conducted at three locations in South Italy between 2017 and 2019 to evaluate the sowing date effect on yield and yield components of three Vicia faba L., originating from cool climates. The results showed that seed yield (SY) and yield components declined with sowing delay. The crop’s environment (year × site) and management (sowing date) were found to explain 34.01% and 42.95% of the total seed yield variation, respectively. The data showed that the tested genotypes were positively influenced by the environment with sandy loam soil and early winter sowing date, resulting in either a greater number of SY and THS than in the other environment. The three faba bean genotypes showed tolerance to winter frost conditions in the two growing seasons.

SummaryFour growth regulators were tested: N-dimethylaminosuccinamic acid (aminozide); N-pyrrolidinosuccinamic acid (F529); 2-chloroethyldimethyldodecylammonium chloride (JF2579); potassium 2(3-chlorophenylcarbamoyloxy) propionate (JF3072); all shortened stems. JF2579 and JF3072 were phytotoxic and lessened yield. Aminozide and F529 (tested in 1970 only) did not affect yield in 1970 but aminozide increased yield by 28% in 1971. Seed rates and row spacings had small effects on yield which varied with season. Growth regulators did not interact with seed rates or row spacing. Plant density and growth regulators had effects on yield via the number of stems and pods per stem. The effects of season on yield were greater and were caused via 100 grain weight. Speculative hypotheses are suggested to explain the different actions of season and treatments.
