تأثير الرش الورقي بالماء الأوكسجيني (HB) والمخصب الحيويEM1 في بعض مؤشرات النمو والإنتاجية لفول الصويا Glycine max. L))

Abstract

The research was carried out at the Sanobar Agricultural Research Station - Lattakia Governorate, during the 2022 agricultural season by planting soybean seeds (Glycine max L.) type Sb237 in experimental plots according to a randomized complete block design (RCBD) with three replicates.

This research aimed to study the effect of foliar spray treatments with hydrogen peroxide (HB) at concentrations of (0, 9 and 18 mmol), and root nutrition with biofertilizer EM1 at concentrations of (0, 4 and 6 ml/m2), on some growth and productivity characteristics of soybeans. Plant height (cm) and a set of indicators were measured: total leaf surface area (cm2/plant), number of pods on the plant (pod/plant), weight of pods on the plant (g/plant), productivity (kg/dunum).

The spraying treatment with hydrogen peroxide (HB), at a concentration of (9 (mmol), and the root feeding treatment with biofertilizer EM1 at a concentration of (6) ml/m2 led to a significant increase (P<0.05) in most of the growth and productivity characteristics and indicators of soybean. The highest values ​​were recorded when adding biofertilizer at a rate of (6 ml/m2) and spraying with hydrogen peroxide (HB) at a rate of (9 mmol) together and reached (92.33 cm, 5106.81 cm2/plant, 90 pods/plant, 81 g/plant, 453.6 kg/acre), respectively. In light of these results, we recommend spraying soybeans with hydrogen peroxide (HB), at a concentration of (9 (mmol), and root feeding with biofertilizer EM1 at a concentration of (6) ml/m2 alone or in com.
