Morphological Characteristics:
After 70 days from sowing, the response of faba bean plants growth to the foliar application of amino and
humic acids and its combination was determined by means of measuring height and branches and leaves
number per plant. Data of table (2) revel that, the majority of all amino and humic acids treatments
significantly increased growth parameters with different extent. In this respect, application of HA at 2000+ AA
at 2000 ppm came in the top of other treatments in increasing plant height as well as branches and leaves
number per plant. On the other hand, no significant differences was observed in all faba bean growth
parameters with the fungicide kocide 101 application as compared to check treatment.
Yield Parameters of Faba Bean:
Data of Table (3) show that treatments of tested amino and humic acids had direct effect on faba bean
net yield. Spraying faba bean plants with HA (2000 ppm) + AA (2000 ppm) significantly improved pods no.
plant-1 and 100-seed weight (192.94 and 25.94%, increase respectively). Both treatments of AA at 3000 and
2000 ppm cam next in increasing 100-seed weight to be 21.51 and 20.24%, respectively. On the other hand,
application of amino and/or humic acids or one of fungicides to faba bean plants have no significant effect
on number of seeds plant-1 as compared to check treatment.
Effect of Amino and Humic Acids on Macronutrients of Faba Bean Plant:
Data in Table (4) show that high significant increase of nitrogen content in seed and straw of faba bean
was observed as response to amino and humic acids applications. In seed, the highest increase was recorded
either with AA (2000 ppm) or with HA (2000) + AA (2000 ppm) while the highest increase of nitrogen in
straw was recorded with A.H. (2000) + A.A. (2000 ppm) treatment.
