Abstract<\/strong><\/span><\/p>\n

The research was carried out during the 2022 growing season at Zahid Water and Irrigation Research Station – Scientific Agricultural Research Center in Tartous- in order to study the effect of agricultural density (20\u00d750 and 30\u00d750 cm) and spraying with the biofertilizer EM1 (control without spraying, 3 ml\/L, 6 ml\/l) in some growth indicators for the two peanut cultivars (Giza 6 and Soori 2): as an indicator: leaf area (LAI), crop growth rate (GCR), relative growth rate (RGR), net assimilation rate (NAR), leaf area ratio (LAR), and leaf area duration (LAD). using split split plot design , as the density occupied the main plots, biofertilization sub-plots, cultivar sub-sub plots ,the treatments were randomly distributed in three replications The results showed that Giza 6 variety was significantly superior to Soori 2 variety in all indicators studied, and the agricultural density (30 x 50 cm) was significantly superior to the density (20 x 50 cm) in the relative growth rate (RGR 0.14, 0.11) g\/g\/day, net assimilation rate (NAR) (0.22, 0.31) kg\/m2<\/sup>\/week, leaf area ratio (LAR) (0.40, 0.47) dm2<\/sup>\/g\/day, and leaf area duration (LAD) (33.66, 45.56) m2<\/sup>\/week, while plant density exceeded ( 20 x 50 cm) significantly affected the crop growth rate (CGR g\/m2<\/sup>\/day) , the leaf area index (LAI) and seed productivity per hectare . As for the effect of biological fertilization on the studied traits, the treatments with concentrations of 3 and 6 ml\/l were significantly superior to the control. The concentration of 6 ml\/l was important in terms of a significant increase in the values of all growth indicators. The results concluded that planting the Giza 6 variety at a density of 30 x 50 cm, spraying it with EM1 biofertilizer at a concentration of 6 ml\/l, gave the highest value for the relative growth rate, net assimilation rate of the plant, and the leaf area ratio, while planting it at a density of 20 x 50 cm gave a positive effect. Significantly greater for crop growth rate and leaf area index and seed productivity per hectare.<\/span><\/p>\n
