Effect On Yield

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.

Background: In Tunisia, chickpea (Cicer arietinum L.) is the second major food legume. The development of chickpea production is facing several biotic constraints. Ascochyta blight (ABL) caused by Ascochyta rabiei (Pass.) Labr. is the most devastating disease and can cause complete yield losses under favorable conditions. In absence of chickpea variety totally resistance to ABL, some methods should be used to control and reduce this disease effects and help for its management. Therefore, this work was undertaken to evaluate the effect of row spacing and seed rate on ABL severity, growth and yield of chickpea. Methods: A split-plot design with three replicates was adopted to carry out this study during 2018 and 2019 cropping seasons. ‘Beja1’ chickpea variety was sown at 40 and 60 cm row spacing and at three seed rates (80, 110 and 140 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 most of the variation in disease severity was associated with seed rate (r=0.61). The highest ABL score severity was noted at 140 kg ha-1 rate. Over both years, wide row spacing and low seed rate reduced ABL severity. Chickpea sown under narrow row spacing (40 cm) produced higher grain yield (1014 and 1099.7 kg ha-1 for 2018 and 2019 cropping seasons, respectively). Grain yield was tending to decrease with increasing sowing rates but at a density higher than optimal, grain yields decrease. In this study, ABL disease severity reached a score of 3.7 and 4.3 in 2018 and 2019, respectively. These disease severities levels had little 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.
