- Abstract
A field experiment was conducted in one of the private farms located in the Abi Gharq area - Babylon province for the autumn season of 2021 to grow the potato crop, Burren cultivar. The study included two factors, the first factor was different levels of bio-health fertilizer at three levels (0, 4 and 6) kg.ha-1 which are symbolized by symbols (D0, D1 and D2). While the second factor represented phosphorous additives at three levels (0, 5, and 100) kg.ha-1 symbolized by symbols (P0, P1, and P2) sequentially. The experiment was conducted in the Randomized complete block design (RCBD). The results showed that adding Bio health fertilizer treatment (D2) gave the highest growth indicators for potato crops, which did not differ significantly from the treatment of adding biofertilizer (D1) for some indicators. Also, treatment (D2) achieved the highest concentrations of nutrients N, P and K in the tubers and the concentration and quantity of nutrients available in the soil after extraction, which was 1.74% N, 0.386% P, 2.63% K, 47.46 mg N, 28.61 mg P and 226.56 mg K and the highest indicators of the qualitative traits of starch in tubers were 12.60%, 12.31% for protein, and 17.60% for the percentage of dry matter in tubers. While the addition of phosphate fertilizer to the treatment (P2) led to an increase in all study indicators of indicators (plant height, number of main stems, leaf area, percentage of chlorophyll) amounting to 54.23 cm, 2.89 stems.Plant-1, 5880 cm². plant, 58.81 spad unit. The treatment of adding phosphate fertilizer to the (P2) treatment achieved the highest yield of tubers, which amounted to 41.07 tons.ha-1.
