Effects of phosphorus fertilization and Pseudomonas fluorescens strain on the growth and yield of faba bean (Vicia faba L.)

Abstract

Volumen 33, Nº 4. Páginas 15-21 IDESIA (Chile) Septiembre-Noviembre, 2015 Effects of phosphorus fertilization and Pseudomonas fluorescens strain on the growth and yield of faba bean (Vicia faba L.) ABSTRACTA field experiment was conducted in Lihijan, Iran in 2013 to evaluate the effect of phosphorus fertilization (P) and Pseudomonas fluorescens strain on the growth and yield of the faba bean. The experiment used a randomized complete block design with a factorial treatment arrangement and three replicates. The experimental factors were phosphorus application (0 and 25 kg ha -1 ) and P. fluorescens strains (non-inoculated, strain 136, and strain 168). ANOVA showed a significant interaction effect of P and P. fluorescens strain on plant height, pod number per plant, 100 grain weight, pod length, and pod and grain yield. ANOVA also showed that grain number per pod was significantly affected by P application and P. fluorescens strain, while haulm yield was significantly affected only by P. fluorescens strain. In the absence of P, the grain yield of inoculated plants was not significantly different from that of non-inoculated plants. In the presence of P (25 kg ha -1 ), strain 168 showed an increase in grain yield of 42% and 65% over strain 136 and non-inoculated plants, respectively. The results indicated that application of phosphorus (25 kg ha -1 ) and seed inoculation with P. fluorescens strain 168 can be recommended to increase grain/pod yield significantly.

Influence of Phosphorus Fertilizer Rates on Yield and Yield Components of Faba Bean (Vicia faba L.) Varieties in Lemu Bilbilo District of Arsi Zone, Southeastern Ethiopia

“…Mean thousand seed weight of faba bean was non-significant (P>0.05) affected by main effect of different rates of P fertilizer and its interaction with varieties ( Table 2). This result is in line with [34] who suggested that effect of phosphorus application on 1000 grain weight was not significant. As [40] suggested application of P at 0-60 kg ha -1 contributes to nutrient absorption (phosphorus, potassium, magnesium and zinc) caused by the increase in soluble phosphorus and assimilation of nutrients to the grain, resulting in larger grains.…”

“…The effect of different levels of phosphorus fertilizer on the number of pods plant -1 was not significant (P>0.05) ( Table 2). This result was disagreeing with [34] who reported that, the number of pods per plant was significantly influenced by application of P. In contrary, on common bean [35] who indicated that all applied P fertilizer rates significantly increased pods per plant over the control and significantly higher number of pods per plant was recorded with P rates of 20 kg ha -1 over rest of the levels. Similarly, [36] also found that faba bean did not respond to phosphorus application in terms of pod number plant -1 .…”

“…Increased soluble P content increased the amount of phytin stored in the seeds. Phytin serves as the main source of stored P in most grains and is an important compound for germination and seed growth with a significant contribution to seed size and weight [34]. According to [31] phosphorus being responsible for good root growth directly affected the thousand grain weight because P at the rate of 0 kg ha -1 (control plots) resulted in the least thousand grain weight.…”

Response of Faba Bean to Phosphorus Fertilization and Zinc Application under Inoculation with Psb

“…These results are consistent with those of other researchers. A similar positive effect was observed by (Rakha and El-Said 2013;Nikfarjam andAminpanah, 2015 andAkl andAbdel-Fattah, 2019).…”

The effect of inter cross-inoculation host group rhizobia on the growth and nitrogen fixation of Faba Bean (Vicia faba L.) varieties in North Showa, Amhara Regional State, Ethiopia

“…Faba bean (Vicia faba) is one of the major cold season food crops grown in Ethiopian Highlands (CSA, 2005). Faba bean has different functions such as providing food and feed that is rich in protein improve soil fertility by symbiotic N 2 fixation with Rhizobium, diversifying the cropping system with crop rotation by reducing constraints on growth and yield of other crops (Nikfarjam and Aminpanah, 2015).…”
