Background: In Tunisia, faba bean (Vicia faba L.) is the first major food legume. The development of faba bean production is facing several biotic constraints. Faba bean Ascochyta blight caused by Ascochyta fabae is one of the most destructive diseases of faba bean and can cause significant yield loss under favorable conditions. As only incomplete resistance ABL varieties are available, some agronomic practices should be applied to control and reduce Ascochyta blight incidence wherever possible. Therefore, this work was undertaken to evaluate the effect of spacing row and seed rate on ABL severity, growth and yield of faba bean. Methods: A split-plot design with three replications was adopted to carry out this study during 2018 and 2019 cropping seasons. ‘Bachaar’ faba bean variety was sown at 40 and 60 cm row spacing and at three seed rates (100, 140 and 200 kg ha-1). ABL severity was assessed visually on a 0-9 scale and agro-morphological traits were measured. Analysis of variance was used to analyze the data. Correlations between agronomic traits, row spacing, seed rate and ABL severity were investigated. Result: Results showed that seed rate has a larger effect on yield than row spacing. In both cropping seasons, the highest grain yield was recorded in 60 cm row spacing and 140 kg ha-1 seed rate treatment. So, this treatment is recommended for obtaining high yield of faba bean. Most of the variation in disease severity was associated with seed rate (r=0.62). The highest ABL score severity was noted at 200 kg ha-1 rate. Over both years, wide row spacing and low seed rate reduced ABL severity. In this study, the small amounts of ABL disease (which reached a score of 5.3 and 4.7 in 2018 and 2019, respectively) had little or no effect on yield.

A field study was conducted in the fall of 2019 to investigate the potential of Arugula (Eruca sativa Mill) aqueous extract as a growth stimulant in enhancing the growth and yield of Fa- ba Bean (Vicia faba L). The study was conducted using sandy soil at a farm in Abo Esaa town in a plot size of 3X5 m2 with a row spacing of 25cm,which based on a complete randomized design (RCD) with four replications, three treatments were carried out, including no foliar spray with E. sativa extracts (control) and foliar sprayed with 20% and 40% aqueous extracts of E. sativa. Ac- cordingly, Faba Bean (Vicia faba L) plants were foliar sprayed six times with the aqueous extracts of E. sativa at rates of 20 and 40% at vegetative and reproductive stages. The result showed that among these concentrations, the foliar spray of faba bean plants with 40% of E. sativa extracts po- tentially were increased all measured growth and yield traits. The results pointed out that plant height increased by 32%, number of branches by 73%, number of leaves by 95%, number of seeds plant by 89%, leaves, stems, pods and roots dry weight by 92%, 80%, 74%, and 89%, respectively. Thus, the study concluded that E. sativa aqueous extracts could potentially be used efficiently by crop producers as a growth enhancer for faba bean crops because of their productivity, great nutri- tive value, low cost, and environmentally friendly nature.

Faba bean (Vicia faba L.) represents a major source of protein for animal and human nutrition, and provides several benefits such as improved soil quality. The Giza cultivar 87 (Vicia faba L.) was evaluated in three different salinity levels (6.9, 8.7 and 14.8 dSm-1) during two successive cropping seasons (2016-2017 and 2017-2018). The experiment was designed to analyze effect of soil salinity on nitrogen fixation, protein, chemical composition and crop productivity (for both grain and straw). Three phosphorus levels and inoculation with Rhizobium leguminosarum bv. viciae were investigated to improve the growth of Vicia faba L under these conditions. Soil salinity levels reduced the grain number and straw weight of plants. Moreover, yield reductions were associated with increasing soil salinity levels confirming salinity effects on faba bean productivity. Salinity induced a significant decreased in all plant growth parameters, plant chlorophyll and grains proteins, as well as increased Na% of faba bean plants. The plants treated with R. leguminosarum bv. viciae showed significant increase in growth traits such as plant length (%), plant fresh weight (%), protein, N-content and dry weight. On the other hand, the dual treatments with R. leguminosarum bv. viciae plus phosphorus gave a great results compared with inoculation or phosphorus alone. Symbiotic nitrogen fixation inoculation enhanced the growth and yield parameters.
