The effect of mycorrhizae fungi، bacillus bacteria with some organic fertilizers on (Solanum lycopersicum var. cerasiforme) grown in unheated greenhouses

The field experiment was conducted in the demonstration farm in Al-Mahnawiyah area-Al-Saddah district, affiliated to Babylon province, which is 20 km east of the province center during the fall season 2024-2025. The study included two factors: the first is adding bio-fertilizer (mycorrhizal fungi and Bacillus bacteria) at levels (without adding, 5 g, 10 g) which is symbolized by (A0, A1, A2) respectively, and the second factor is adding organic fertilizers, including (Vermicompost, poultry waste, mushroom waste, and palm frond waste) at levels (10 tons. ha-1 for all types of fertilizers) which is symbolized by (B0, B1, B2, B3, B4) on the growth and productivity of cherry tomato plant. The experiment was conducted using the split plot system within the randomized complete block design (RCBD), where the land was divided into three terraces, each terrace was replicated and contained 15 experimental units. Cultivation was conducted on both sides of the terrace and drip irrigation was used. The averages of the treatments were analyzed using the least significant difference (L.S.D) test at a probability level of 0.05. The results showed that the biofertilization with mycorrhizal fungi (A1) had the highest significant increase in chlorophyll, which reached 51.86 Spad, the highest average stem diameter of 15.623 mm, the highest percentage of dry matter of the vegetative group of 24.61%, the highest percentage of nitrogen, phosphorus and potassium elements of 3.772%, 0.5246%, 1.5419% respectively, and the highest yield per plant, which reached. The treatment with Bacillus bacteria (A2) recorded the highest average leaf area of ​​3229 cm.plant-1. The results showed a significantly excelled in organic fertilization treatments, where the treatment with palm frond waste (B4) was excelled in giving the highest rate of chlorophyll 51.67 Spad and the percentage of dry matter in the vegetative group 24.50%. The treatment with poultry waste (B2) gave the highest rate of stem diameter 15.188 mm and leaf area as it reached 2781.7 cm. plant-1 and the percentage of N element 3.648%. The treatment with vermicompost (B1) was excelled in the percentage of phosphorus element 0.4983% and the highest yield per plant. The results of the interaction between the factors indicated a significantly excelled, as treatment A1B2 achieved the highest rate of stem diameter 16.313 mm, percentage of dry matter of the vegetative group 27.14%, leaf area 3918.1 cm.plant-1, nitrogen percentage 4.237% and the highest yield per plant. Treatment A2B4 achieved the highest rate of chlorophyll content of leaves, reaching 52.62 Spad, and treatments A1B1 and A1B4 recorded the highest percentage of phosphorus 0.5907%.
