Effect of Different Concentrations of Nano-Magnesium and Nano-Titanium Oxide on the Cumulative Mortality of Larvae of Two Species of Cucurbit Fruit Fly Affiliated With the Dacus in Iraq

An experiment was conducted in sandy clay loam textured soil at the research station of the College of Agriculture / University of Anbar to find out the effect of adding white Spent mushroom residues Agaricus bisporus, date residues and bacterial inoculum on the growth and yield of broccoli. A three-level factorial experiment was designed for this purpose: the first is white mushroom residues with three levels [0, 10, and 20 tons ha−1] and symbolized by symbols [M0, M1, and M2], and the second date residues with three levels [0, 10 and 20 tons.ha−1] and symbolized by symbols [D0, D1, and D2] and the third factor is bacterial inoculum [Azotobacter chroococcum+Pseudomonas putida] which included two levels; No addition [B0] and inoculum addition [B1], added with all the mentioned treatments half of the fertilizer recommendation. The experiment was designed with a randomized completely blocks design [RCBD] and three replications. The results showed that the triple interaction of the treatments at the highest levels [B1D2M2] gave the best results and significantly for Plant height [PHA], Leaf Area [LA], number of leaves [NOL], number of secondary heads [NOSH], weight of the main flower disc [NOMF] and diameter of the main flower disc [DOMFD] ]75.30 cm, 1182.70 cm2 plant−1, 70.22 leaf−1, 13.53 plant heads−1, 1515.50 g and 26.49 cm] respectively. The control treatment with no residues and no bacterial inoculum [B0D0M0] was added reveal the lowest rates for all the mentioned properties.

A plastic pot experiment was carried out for the agricultural season 2021-2022 in the fields of the College of Agriculture-University of Anbar and located at 30° north latitude and 43° east longitude, in order to know the role of foliar spraying of wheat plants with humic acid at concentrations of 0 mg.L−1 (H0), 0.75 g.L−1 (H1) and 1.5 g.L−1(H2) and the added zinc element sprayed with concentrations: 0 mg.L-1 (Zn0), 60 mg.L−1 in the form of nano-zinc oxide (Zn1) and 120 mg.L−1 in the form of traditional zinc oxide fertilizer (Zn2). A factorial experiment was designed according to the sectors Randomized complete set (R.C.B.D) with three replications The results of the statistical analysis showed that there was a significant increase in foliar spraying with humic acid and for all concentrations, with superiority for the highest concentration, as well as when feeding with nano particles and traditional zinc, with a clear superiority of nano particle zinc in all the studied characteristics: Plant hight, leaf area, spike length, seeds yield, and zinc concentration in seeds:(61.67 cm, 24.51 dm2 plant−1, 12.33 cm, 8.05 gm, pot−1, 14.00 mg kg−1) compared to control treatment H0Zn0 :(46.00 cm, 16.13 dm, plant−1, 8.67 cm, 6.28 gm−1, 7.80 mg kg−1) respectively Start your abstract here…

The Role of Biochar and Phosphorus in the Growth and Yield of Potatoes

Two experiments were conducted, first was a laboratory to prepare plant charcoal from three different sources: rice straw, corn cobs, and sugarcane (B1, B2, and B3), with the aim of loading them with phosphorus from the superphosphate fertilizer source (21% P) at three levels of phosphorus: 50%, 75% and 100% of the recommended fertilizer for potatoes (F1, F2, and F3). Then, tested in a field experiment conducted at the agricultural research station of Anbar University’s College of Agriculture in Albu Etha-, located at longitude E43.32.65 and latitude N33.45.37 in the fall season of 2022. The soil texture was sandy clay loam and the irrigation system was drip irrigation. Burren potato variety was planted to study the effect of adding three types of plant charcoal, supported with different levels of phosphorus, and using them as slow-release fertilizers on the availability of phosphorus and some properties and growth and yield of potato. The experiment followed a randomized complete block design with three replicates. The results showed a significant superiority of all plant charcoals supported with phosphorus compared to the treatment without adding charcoal. The treatment that added sugarcane waste charcoal (B3) recorded the highest value in all studied plant characters and yield (plant height, chlorophyll content of leaves, number of aerial branches, dry matter yield, total tuber yield, and marketable tuber yield).
