The purpose of this study is to investigate the impact of the use of Vermicompost and Vermicompost tea on the growth and yield of broccoli and some soil properties The field experiment was formed In Saqlawiyah sub-district - Anbar–Iraq on 10 October 2019.The experiment lasted approximately three months. In situ analysis and measurements of plant and soil were carried out at the site of the experiment, and also in the laboratories of the Agricultural Research Center, Soil Research Department in Abu Gharib. The treatments consisted of (T1 soil only, T2 DAP chemical fertilization only (according to fertilizer recommendation) 240 kg DAP.ha -1,T3 = 8.ton ha -1 Vermicompost mixed with soil + half the recommendation of 120 kg DAP. ha-1,T4 = 16 tons. ha-1 Vermicompost mixed with soil + 120 kg DAP. ha-1T5 = Vermicompost tea spray on the plant + 120 kg DAP. ha-1 ,T6 = 8 tons. ha-1 Vermicompost mixed with soil + Vermicompost tea sprays on the plant + 120 kg ha-1 DAP.. The plant traits were; plant height (cm), the total number of leaves (leaf. plant -1), the leaf area (dcm2.plant -1), vegetative dry weight (g. plant -1), dry weight of rhizosphere (g.plant-1), the weight of the main flower (gm) which were (52.8, 42.4, 98.6, 190.2, and 865.8), respectively, as well as the percentage of protein%, fat%, N%, P%, and K% that reached (23.37, 2.81, 3.74, 0.79, and 2.93) successively.concluded from this study that the treatment of Vermicompost with Vermicomposting tea combined with half of the fertilizer recommendation enhanced growth and yield of Broccoli plant and some soil properties.
Geographic techniques were used to select the sites of water harvesting systems within the Horan basin. Analytical Hierarchy Process (AHP) and pairwise comparison were used to determine the importance of selected traits for water harvesting (soil texture area, runoff, Land cover,). A total of 96 water harvesting sites were identified, of which 11 were found to be the most important. The results showed that the use of AHP to compare the pairs of traits affecting water harvesting. There are several promising areas for harvesting, totaling 96 sites, distributed between sandy and loamy sand and sandy clay loam. With 11 sites characterized by sandy clay soil and high surface runoff. The site 41 has the highest weight in the selected traits 0.557, while the site 84 was the lowest weight and reached 0.339 in terms of importance. The total area of the 96 study sites reached 35402.48 ha, which constitutes 19.7% of the area of the valley, while the area of the most important sites for harvesting, which amounted to 11 sites (633.49) ha, which constitutes (0.35%) of Total area of the valley and 1.7% of the total area of the water harvesting sites. The volume of water collected at all harvest sites (96 sites) was 20288131.92 m3, 567159.58 m3. The correlation between the different characteristics, the derivation of a mathematical equation that reflects the values of the best sites using a program, and then a map of calculated values, is calculated to determine their suitability in the application.
A field experiment is carried out in private farm of Silty loam textured soil, in Al-Latifiya, district southern Baghdad, Iraq during the spring season of 2018. The objective is to study Maize’s adaptability (Zea mays L.) plants to drought using water stress and Salicylic acid foliar application by determining some growth traits. A split-split plots system is used within Randomized Completely Block Design (RCBD) with three replications. The main plots include three irrigation treatments (IQ); 100% (full irrigation), 80% and 60% available water. The subplots involve four Salicylic acids (SA) concentrations; 0, 100, 200 and 300 mg.L-1. The results were as follows: The Salicylic acid (SA) has shown a clear significant effect in all characteristics. The (300 mg.L-1) concentration of SA gives the highest rates of growth traits. Similarly, the irrigation treatments have shown a clear significant effect on all traits. The full irrigation treatment gave highest rates on growth characteristics; leaf area (LA), leaf area index (LAI), plant’s height (PLH), number of leaves per plant (LN). Therefore, this study suggests the possibility of making Maise plants (Zea mays L.) more adaptable to drought tolerance using water stress and Salicylic acid foliar application. Such tolerance leads to reduce plant water requirement without significant effects on growth and yield characteristics as well.
