“…This is contrary to the findings of other studies [28], which indicated that application of P alleviated the adverse effects of water deficit stress by increasing root dry weight, length and surface area. The high available soil P might have offset this contribution of P for plants grown under water deficit conditions.…”

“…Cellular water deficit mostly result in a concentration of solutes, loss of turgor, denaturation of proteins, disruption of membrane integrity, decrease in cell expansion and failure of photosynthetic process [28]; these might interfere with the formation of dry matter in the source tissue and its further accumulation in the sink. [34] also reported reduced grain weight of faba bean cultivars due to water deficit stress.…”

A green house experiment was conducted at Dejen, Northwest Ethiopia, with the objective of quantifying the critical soil water deficit and P levels that affect yield and yield components of soybean, and determine the critical soil water deficit levels influencing P uptake in soybean. The treatment consisted of factorial combination of four available soil water (ASW) deficit levels (0%, 25%, 50% and 75%) and four levels of phosphorus (0, 10, 20, and 30 kg•ha −1 ) laid out in RCBD with four replications using soy bean variety Jalale as a planting material. The experiment was conducted under green house condition at Dejen, South Ethiopia during the 2011 academic year. Air dried soil was filled in the pots and seeds were sown on May 13, 2011. Four plants were maintained on each pot after thinning till flowering but after flowering, the total number of plants per pot was reduced to three as one plant which was used for measurement of root biomass. The water deficit treatments were imposed after the plants have been fully established 2 weeks after emergence just before branching stage. The water deficiency was imposed through maintaining the soil moisture content below field capacity at the deficit levels of 25%, 50% and 75%. The 75% of ASW deficit resulted in the longest days (45) to flowering and maturity (99) compared to the 0%, 25% and 50% deficit levels. Also, the 75% of ASW deficit level resulted in shorter plants (55 cm), the lowest leaf area (82.6 cm 2 ), the highest root to shoot ratio (0.0168) and the lowest DM accumulation (161.3 gm −2 ) compared to the other ASW deficit levels. Likewise, the 75% of ASW deficit level gave the lowest number of pods per plant (4.13), seeds per pod (1.69), 100 seed weight (2.54 g), seed yield (13.4 g•m −1 ), above ground biomass (174.6 g•plant −1 ) and harvest index (0.08) compared to the other ASW deficit treatments. The degree of sensitivity to drought increased dramatically (from 0.0423 at 25% to 0.9604 at 75%) with increase in water deficit level. Tissue analysis results indicated that the highest seed P concentration (1.285%) and uptake (432.5 g•plant −1 ) were ob-M. Getachew 1890 tained at the 0 ASW deficit and 30 kg•P•ha −1 and the lowest were obtained at 75% ASW deficit and all rate of applied P. On the contrary, the highest straw P concentration (1.88%) and uptake (552.7 g•plant −1 ) were recorded at 75% and 25% of ASW deficit levels and 30 kg•P•ha −1 , respectively. However, the total P uptake was influenced only by ASW deficit levels in that the relatively minimum and maximum values were observed at 75% and 0% of ASW deficit levels, respectively. It can be concluded that the critical ASW deficit levels that affect yield and yield components of soybean and uptake of total P lie between 25% and 50% of available water deficit levels. The parameters started to decline significantly from the 50% of ASW deficit onwards. As it is a green house experiment, further study on more number of ASW deficit levels and soil types under different field conditions needs to be ...

“…This indicates that soil solarization had provided a very good control of O. crenata because the experimental field was naturally infested with parasite seeds. The experimental data obtained from the control plots describing the effects of temperature and soil moisture on faba bean root and shoot growth have been reported elsewhere (Manschadi et al ., 1998a,b). In this paper, we present the results of O. crenata infested plots.…”

Quantitative aspects of Orobanche crenata infestation in faba beans as affected by abiotic factors and parasite soil seedbank

The interactions between the root parasitic weed Orobanche crenata Forsk. and its host plant faba bean (Vicia faba L.) were quantified under controlled and field conditions at ICARDA’s Tel Hadya research station. In the field experiments conducted in 1993–94 and 1994–95 faba beans were sown on two dates, in plots with 0, 50, 200 and 600 O. crenata seeds kg–1 soil, under both limited and sufficient moisture supply. The effects of temperature on the duration of the early developmental stages of O. crenata were investigated in a growth chamber. The extent of O. crenata infestation was closely related to the number of parasite seeds in the soil. The seed‐density treatment with 600 seeds kg–1 soil resulted in complete crop failure. Furthermore, O. crenata infestation was higher under sufficient than under limiting water supply conditions, irrespective of sowing date. Only in the moderately infested plots, did shifting of the planting time of faba bean result in a significant decrease in parasite dry weight and an increase in crop seed yield. The timing of germination, attachment and further developmental stages of O. crenata was not related to faba bean growth stage and was affected primarily by soil temperature. The duration of O. crenata developmental stages was estimated using the thermal time concept. The relationship between total number of parasite attachments at the harvest of the faba bean crop and O. crenata seed density was dependent on maximum faba bean root‐length density measured by the start of pod‐filling in each treatment combination of sowing date and moisture supply. The results are discussed with reference to implications for the development of a dynamic simulation model for the prediction of faba bean yield losses caused by O. crenata.

“…Their mean bulk density was 1.49 g cm -3 ; OM was 2.8%, and AWC 5.65 cm (Table 1). Soil depth differed between these soils (40 and 70 cm, respectively) but broad bean is a shallow rooted crop with 60% of its roots in the top 15 cm of soil; therefore, the 40 cm soil depth of TLG was not considered to be a limitation (Manschadi et al, 1998) , 1997). Soil at TCA was an Ochreptic Haploxeralf, a deeper soil with higher organic matter content due to its volcanic origin (Table 1).…”

Broad bean (Vicia faba L. [unranked] major (Harz) Beck) is usually consumed dry. In Chile, however, broad bean is grown as a vegetable crop with indeterminate genotypes. The new 'Alargá', 'Retaca' and 'Verde Bonita' broad bean genotypes, which have a determinate growth habit, were evaluated in six irrigated environments in central Chile at three locations (Rancagua, Talca, and Talagante) and on two planting dates (F1 and F2; 1-mo apart). The aim was to characterize their yield and select the best-yielding genotypes in terms of pod yield (PY) and fresh grain yield (GY). The best location(s) to produce fresh pods and fresh grain were also identified and described. Fresh grain yield and components were measured and the genotype × environment interaction (G×E) was analyzed. Pod yield differed among genotypes; 'Verde Bonita' and 'Retaca' had the highest PY (15 500 kg ha -1 , 8% higher than 'Alargá'). There was a G×E interaction for GY and 'Retaca' had its highest yield in Talca on the two planting dates and in Rancagua when planted late (F2). Mean GY of 'Retaca' was 3900 kg ha -1 with the highest number of grains per 1 m 2 (NG). The best GY was related to a higher seasonal photothermal quotient (ranging from 1.15 to 1.82 MJ m -2 d -1 °C -1 , r = 0.90, P ≤ 0.001). The lowest GY was in Talagante on F1. Genotypes differed in yield composition; 'Retaca' had many small pods giving many seeds per unit area and 'Verde Bonita' had large pods yielding fewer grains per unit area. The 'Retaca' genotype is preferred by the frozen broad bean industry, whereas 'Verde Bonita' is preferred by the fresh broad bean market.
