تأثير أضافة المولبيدنم في نمو و مكونات حاصل فول الصويا

Abstract EN

Field experiment was conducted in silty clay loam soil using a randomized complete design with four replicates.

The objective of this study was to evaluate the addition of molybdenum fertilizer on soybean.

The treatments consisted five rates of Mo fertilizer (i.e., 0, 1, 2, 3 and 4 Kg Mo ha-1) and their effects on growth and yield components.

Results showed that applied of Mo statically enhancing soybean potentiality and Mo and N absorption.

Increasing the level of Mo from 0 to 2 Kg ha-1 significantly increased dry matter yield, grain yield, protein content, N and Mo uptake by 89, 55, 72, 38 and 810% respectively.

The results of the regression technique confirmed that curvilinear trends were found between plant parameters and Mo fertilizer.

The optimum level for improving yield potentially was 2 Kg Mo ha-1.

We conclude that addition of 2 Kg Mo ha-1 was enough to increase the efficiency of biological nitrogen fixation and production of soybean.
