Effect of bio-organic fertilizers on faba bean growth, yield and soil health

الملخص EN

Field experiments were carried out during two successive winter seasons of2018/2019 and 2019/2020 in a sandy soil to evaluate the effect ofbio-organic fertilizers on growth, yield of faba bean varieties cultivated in a newly reclaimed and soil health.

Varieties of three faba bean were used as main plot, compost and Rhizobium leguminosarium were used individually or mixed as sup plot, recommended nitrogen rate (RN) used as control.

The obtained results revealed that a significant variance among varieties with all parameters investigated, Nobaria 3 recorded the highest values of plant height in the two seasons.

On the other hand, Giza 843 variety recorded the lowest values at the two seasons.

The highest values of plant height were recorded by using mixed fertilizers plus 75% MF.

Likewise, Giza 716 give the highest values in chlorophyll content in two seasons.

Nobaria 3 give the highest yield 1297Kg/ fed followed by Giza 843 then Giza 716, and the highest values were obtained with mixed amendments of 2.5 compost +R.

leguminosarium + 75% MF.

Soil health was determined by dehydrogenase activity and CO₂ evaluation in the Rhizosphere soil.

The highest values were obtained with mixed amendments compared to control and other treatments
