Relationship between the Dynamic Characteristics of Tomato Plant Height and Leaf Area Index with Yield, under Aerated Drip Irrigation and Nitrogen Application in Greenhouses

The current study was undertaken to investigate the dynamic characteristics of tomato crop, such as its plant height and leaf area index (LAI), based on effective cumulative temperature. This assessed under aerated drip irrigation (ADI) conditions application a specific nitrogen (N) dose, their relationship with yield crop formulated. conducted in greenhouse located Zhengzhou, Henan province, China. assessment were two methods, ADI conventional (CK), three N rates, i.e., 0, 140, 210 kg ha−1. logistic Richards models used fit equations for LAI different treatments quantify characteristic parameters understand yield. results revealed that growth fitted well model at R2 > 0.98 (p < 0.01), regardless treatments. found significantly increase maximum rate average over rapid period LAI. They also noted reduce temperature which entered 0.05), thereby increasing time spent nutritional phase. is an essential precursor better development subsequent reproductive organs. Tomato yields confirm it: highest 85.87 t ha−1 obtained treatment, 13.8%, 12.2%, 39.6% compared CK–210 ha−1, ADI–140 ADI–0 treatments, respectively 0.05). Grey correlation analysis showed closely related all from Furthermore, it observed slow phase key affecting provides scientific basis regulating dynamics vegetables facilities application.
