Leonardite is a common mineral that contains a lot of organic matter. It may have a beneficial influence on plant growth and nutritional content. The objective of the present study was to determine the effect of four different leonardite doses (0, 20, 35, and 50 g kg-1), three different phosphor rates (0, 50, 100, and 150 mg kg-1P), on plant growth, and nutrient uptake of Cucumber (Cucumis sativusL.). plants. The experiment was conducted in a plastic house. Increasing the leonardite dose statistically increased the concentrations of N, P, K, Mg, Cu, and Mn in the cucumber leaves, but Zn content (34.711 a) mg kg-1of the leaves was significantly higher only with the (20 gm) of leonardite. The highest phosphor application (150 mg kg-1) increased leaf N, P, K, Ca, Mg, and Mn concentrations compared with the other three doses and also the leaf Zn levels statistically did not increase as the P applications increased from (control to 150 mg kg-1). Based on the number of fruits per plant, the best interaction among leonardite doses and phosphor rate were a combination of the (35gm×100 mg kg-1) increasing the numbers of cucumber per plant (48.000a).

Four plant extracts: Eucalyptus (Eucalyptus sp), Onion (Allium cepa Linn), Garlic (Allium sativum) and Cinnamon (Cinnamomum sp) with three extraction rates (0, 1 and 3) % in 2016 and 2017 seasons were used against aphid population in broad bean (Vicia faba). Some plants characteristic; Plant Height (cm), Fresh Weight.Plant-1 (g), Dry Weight.Plant-1 (g), Number of Pods.Plant-1, and aphid’s dead number after 6 hours and 24 hours were taken. Eucalyptus affected significantly on Number of Pods.Plant-1compared with the other extraction (7.416). As the extraction rate increased, all parameters increased. Pearson’s correlation test for traits in 2017 season indicated that there were a significant strong correlate and better than 2016 season among Number of Pods .Plant-1, Fresh Weight.Plant-1 (r = 0.770**), Dry Weight .Plant-1 (r = 0.816**), and M24 (r = 871**). Based on Number of Pods.Plant-1, the best interaction between the season, extraction types, and extraction rates, was a combination of the 2017 season × Eucalyptus extraction × 1% Extraction rate.

The seeds of the Somar variety (local production) were planted in mid of October (after being soaked with water for 16 hours) in panels 1.5 x 2 meters. Broad bean (Vicia faba var. Somar) was studied in outdoor to determine the effect of three planting distances (20, 25 and 30 cm), four different Humic Acid (HA) concentration doses (zero, 1.5, 3.0 and 4.5) ml / liter H2O, with three replicates on some of the plant’s vegetative and yield traits; Plant Height (cm), Plant Diffusion (cm), Number of Branches /Plant, Number of Flowers / Plant, Number of Pods / Plant, % percentage of Pods Set, Total Pods Yield /plant (gm), Pod Weight (gm). The (HA) were added by spray way directly to the top of the soil with two applications, the first after 3 weeks from complete germination, while the second after branching immediately. The experiment was designed as Randomized Complete Block Design (RCBD). Based on Total pods yield / plant (gm), the best interaction between the plant distance and different concentration of (HA) was a combination of the planting distance 30 cm, and treated the soil with 3.0 ml/ literH2O.
