تأثير مستويات مختلفة من السماد المحقون بسمادة فارق الضغط على نمو وإنتاجية سلالات من الفلفل في البيوت المحمية

Abstract EN

An experiment was conducted to find out the effect of three levels of injected fertilizer at concentrations of 12, 24, and 36 parts per million (mg/l) compared to ground fertilizer added to the soil (control) on four strains of Italian pepper varieties and their source effect on productivity and nitrogen concentration in the soil and plant leaves.

The results showed that the highest productivity levels of injected fertilizer were 36, 12, 24 ppm, respectively, without significant differences.

The injected fertilizer was superior to the ground fertilizer with a significant difference for all levels of the injected fertilizer.

As for the cultivars, strain 308 had the highest productivity without a significant difference with strain 305, but with a significant difference for strains 306 and 307.

As for the overlap study, the ppm concentration was 24 with the fourth strain by 4.09, then the first strain with ppm concentration.

12 Here, we notice the difference in the response of the strains to the injected fertilizer, and the concentration of nitrogen in the leaves of the pepper plant was at levels of 3.25% close to the ideal, compared to 2.7% in the ground.
