| Abstract | ||||
| This study was conducted during the two successive seasons of 2016and 2017 at khamisa research station farm of Desert Research Center, under Siwa Oasis – Matrouh Governorate – Egypt on Conadria fig cultivar grown under salinity stress to study the effect of some biological compounds (biomagic, yeast and biovite) on improving productivity. Four treatments of foliar applications :(T1): tap water, biomagic at 7.5% (T2), yeast extracts at 5g/l (T3), and biomgic7.5% + yeast extracts 5g/l (T4) sprayed once every two month starting from January until the harvest time. In addition, soil inoculated twice at (January and March) in the rizosphere area with irrigation water by three treatments (control 0 (B1), 100 ml/tree (B2) and 200 ml/tree (B3) of biovite suspension 1%. The obtained results revealed that all treatments were very effective on growth parameters, yield (fruits number and weights) for etch of ―boni-crop‖, ―main-crop‖ and final crop in addition to fruit physical and chemical characteristics. Generally, T4 under B3 increased shoot length, leaves number /shoot, leaf area, leaf total chlorophyll, number of fruits (boni-crop), number of fruits (main-crop), total number of fruits, weight of fruits (boni-crop), weight of fruits (main- crop), total yield, fruit weight, fruit height, fruit diameter, total soluble solid, reducing sugars, non- reducing sugars, total sugars and decreased total acidity in both seasons. It is also clear that B3 increased total microbial account with plant growth reaching their highest figures after 90 days from inoculation. In addition, B3 decreased EC, pH, Na, and Cl in soil at the end of each seasons. | ||||
