Irrigation quota and organic fertilizer application had a highly significant impact on pumpkin vine length and stem diameter (P < 0.01), with a significant interaction between the two factors (P < 0.05).
Irrigation quota and organic fertilizer application had a highly significant impact on pumpkin vine length and stem diameter (P < 0.01), with a significant interaction between the two factors (P < 0.05).
Conversely, the relationship between organic fertilizer amount applied and pumpkin yield exhibited an initial increasing trend, followed by a decreasing trend, indicating the existence of an optimal fertilization level.
