Effect of Bio_fertilizers on Growth and Medicinal active compounds Content of Olive Transplants

Abstract

A study was carried out in central nursery in Kut affiliated to Wasit Agriculture Directorate on 18/09/2020 to study effect of adding Azotobacter chroococcum and Bacillus megatherium on growth, leaf mineral content and medicinal compounds of “Qaisi” olive transplants. This experiment was carried out on 81 olive transplants with homogeneous vegetative growth as much as possible. Two factors were used in experiment; first factor is addition Azotobacter chroococcum bacteria (A) with three levels: no addition (A0), addition of 30 ml.pot-1 (A30) and addition of 60 ml.pot-1 (A60) and second factor is three levels of Bacillus megatherium (P) is without addition (P0), adding 30 ml.pot-1 (P30) and adding 60 ml.pot-1 (P60).Treatments were replicated three times (three transplants in experimental unit) at factorial experiment in a RCBD. experimental results showed; adding Azotobacter chroococcum to soil at 60 ml.pot-1 (A60) significantly increased in transplant height of 5.78 cm, highest leaf area of 8.99 cm2, highest Branches number of 10.67 branches transplant-1, highest Leaves Carbohydrates content of 4.54 %, highest leaf Caffeic acid content of 14.63 mg.g-1 and highest leaf Vanillic Acid content of 16.90 mg.g-1, also results shows that adding Bacillus megatherium to soil at 60 ml.pot-1 (P60) gave highest increased in transplant height of 5.64 cm, highest leaf area of 8.84 cm2, highest Branches number of 9.78 branches transplant-1, highest Leaves Carbohydrates content content of 4.62 %, highest leaf Caffeic acid content of 15.59 mg.g-1 and highest leaf Vanillic Acid content of 17.89 mg.g-1,

Response of Olive Trees (Olea europaea L.) cv. Zaity to Bio health and Foliar Spray of Tecamin max and Boron

“…Pulp: stone ratio: As can be seen from table (8), there was no discernible impact of pulp: stone ratio when bio health was applied to the soil and tecamin max and boron were sprayed onto the leaves. The interaction between bio health + tecamin max and bio health + boron displayed that there was no significant effect of pulp: stone ratio, while the interaction between tecamin max + boron, the highest value (3.08) was obtained at 0 ml.…”

“…The plant is also found most probably growing wild in MAM: Dihey village, about 65 km North Duhok, altitude 985m; Bekhair mountain, West Duhok altitude about 130m, North West facing, near Syria frontier (31). In 2020, estimated number of olive fruitful trees growing in Iraq, including nearly 1329191 tree produces up to 33912 tons, and average production per tree 25.51 kg (8). While acreage of olive in the world reached about 10578246 hectares, with production of 19464495 tons (5).…”
