The effect of multifunctional biological products for soil improvement on the height of the main stem of peanutsThe height of peanut plants in both the control model and the model using biological products to improve soil increased during the growth and development of peanut plants. The plant height reached its maximum at harvest (Table 3). However, at each growth stage, the height of peanut plants varied between the two models, which followed different cultivation practices. At harvest, the average height of peanut plants in model 1 was 38.7 %u00b1 0.78 cm, while model 2, which incorporated the use of multifunctional biological soil improvement products, achieved a higher average plant height of 46.3 %u00b1 0.89 cm. This suggests that the application of soil-improving biological products in model 2 positively impacted peanut plant growth compared to Model 1.Table 3.
