Effect of Row Spacing and Plant Density on the Yield of Faba bean L. Under Very Differentiated Humidity Conditions

Abstract

The research covered Polish low-tannin Faba bean ‘Albus’, and its yielding depending on the row spacing and plant density under very different humidity conditions across the research years. The mean multi-year faba bean seed yield was 4.01 t ha-1 and it was most correlated with the total rainfall in August and in June-August. Due to a considerable variation in the total rainfall and air temperature, the faba bean seed yield ranged from 0.69-2.14 t ha-1 in dry years (2018-2019) with high air temperature, from 6.64 to 6.59 ha-1 in humid years (2016-2017) with a considerably higher total rainfall and lower air temperature in June-August. There was no significant effect of the row spacing and plant density on the faba bean yielding, except for a significantly lower seed yield in 2019 following the application of the lowest plant density. Out of all the yield structure components, only the number of pods per plant for 60-75 plants per m2 was significantly lower than for 45 plants. The other yield structure components did not differ significantly due to the factors studied either, except for the LAI, the value of which for a narrow row spacing was significantly higher. There was found a significant correlation between all the plant traits and with the faba bean yield.

“…Stated differently, the optimal plant density in terms of the number of shoots per plant in both seasons was found to be 20 kg/fed. The present results is confirmed with those obtained by [28][29][30][31][32][33][34].…”

Effect of Weed Control Treatments and Row Spacing on the Yield and its Components of Faba Bean and Companion Weeds

“…The reason for the decrease is due to the increase in the number of plants per unit area and thus the increase in competition between the crop plants for light and nutrients, which led to a decrease in the chlorophyll index in the leaves (Table 3), and their low efficiency in absorbing light, and then the decrease in the effectiveness of photosynthesis and the transmission of its products to the emerging flowers, which reduced the proportion of fruit set in them and thus the decrease in the number of pods in the plant. This result agrees with [11][12][13][14], they found that higher plant densities resulted in fewer pods per plant. No statistically significant interaction was found between the study parameters and this characteristic, either.…”

“…The planting population of crops is important for large-grained seed varieties and it has been recognized as the main determinant of crop yield (Janusz, 2022). Optimal plant density (that is, the smallest population that produces the highest yield) and the appropriate design of plants per area allow crops to use resources in the best way and produce maximum grain yields (Kebede, 2020).…”
