The study was done in a greenhouse at the department of Horticulture and Landscape Gardening, College of Agriculture, University of Anbar for the growing season 2019-2020. It was designed to study the effect of the agricultural media and spraying with nano and normal zinc and iron on the traits of flowers and yield of Strawberry (CV. Festival) under the protective environment conditions. Three agricultural media were used for the first factor included: (River soil and Peat moss 3:1), (River soil and “50% Coantail + 50% Alfalfa” 3:1) and (River soil and poultry waste 3:1), presented with symbols (M1, M2, M3), respectively. The second factor consisted of spraying with zinc and iron nano and normal with the following concentrations (normal-Zn 50 mg L-1, nano-Zn 10 and 20 mg L-1, normal-Iron 150 mg L-1, and nano-iron 20 and 40 mg L-1) in addition to the control treatment (distilled water), mentioned as (S0, S1, S2, S3, S4, S5, S6), respectively. The results revealed that planting Strawberry in different media had a significant effect on flower traits and yield especially the media culture (M3) which presented the best results for the traits (number of flowers, percentage of flowers set, number of fruits, weight, length and diameter of fruit, and yield), which reached (34.4 flower plant-1, 77.5%, 28.4 fruit plant-1, 21.50 g, 4.28 cm, 3.37 cm and 628.1 g plant-1). On the other hand, the media culture (M3) caused a reduction in the percentage of the fruits malformation to a minimum value of (14.9%). Spraying with nano-zinc and iron and normal zinc and iron achieved significant effect, especially (S5), that gave the highest values for the traits ( number of flowers, percentage of flowers set, number of fruits, weight, length and diameter of fruit, and yield) which were (32.8 flower plant-1,76.5%, 25.6 fruit plant-1, 21.12 g, 4.20 cm, 3.42 cm, and 554.4 g plant-1) respectively. On the other hand, (S5) concentration caused a reduction in the percentage of the fruits malformation to a minimum value of (14.2%). The interaction between the two factors of the study in all of the responses studied. The treatment interaction (M3S5) gave the best results for traits (number of flowers, percentage of flowers set, percentage of the fruits malformation, number of fruits, weight and length of fruit, and yield), which reached (42.0 flower plant-1, 83.4%, 11.8%, 31.2 fruit plant-1, 25.58 g, 4.72 cm and 782.4 g plant-1), respectively. On the other hand, the treatment interaction (M2S4) showed the highest value of fruit diameter (3.84 cm).

The following study was conducted in a private date palm orchard in the area of AlFurat, district of Heet throughout the season of 2019-2020 on 20-year-old date palm trees, Zahdi cultivar. The purpose was to study the effects of spraying the Urea compound with concentrations of (0, 1 and 2 g L-1) as well as seaweed extract (Tecamin Algae) with (0, 2 and 4 g L-1) of concentration on the growth and chemical content of the trees. 27 date palms were randomly selected. A factorial experiment with RCBD design was carried out such that it includes 9 treatments with 3 replicas for each treatment. Each tree was treated as one experimental unit. The results demonstrated that treatments of Urea spraying, especially with 2 g L-1 concentration, contributed to achieving the best results for response measurements (Leaf Area, Total Chlorophyll, Total Carbohydrates in the Leaflets, Nitrogen, and Phosphorous), which were (2.61 m2, 10.65 mg g-1, 7.46%, 1.69% and 0.40%), respectively. The content of phosphorous in the leaflets was not significantly affected when sprayed with Urea. On the other hand, seaweed extract spraying had a significant effect on all the response measurements. The 4 ml L-1 concentration gave the highest figures for our responses (total chlorophyll 10.38 mg g-1, Carbohydrates 7.52%, Nitrogen 1.65%, Phosphorus 0.37% and Potassium 0.67%). The concentration of (2 ml L-1) gave the largest area of the leaf at 2.63 m2.

The study was conducted in the lath house of the Department of the Horticulture and Landscape - College of Agriculture during the growing season of 2020-2021 inGazania plants, in order to study the effect of ground addition of marine algae extract (Tecamin Algae) at concentrations (0, 2 and 4 ml L-1), symbolized by (A0, A1 and A2) respectively, and spraying with the nanostimulator (Proteck CalBor) manufactured according to nanotechnology in concentrations (0, 0.5 and 1 ml L-1) and it has a symbol (B0, B1 and B2). The results showed that the treatments of adding the extract (Tecamin Algae), especially at concentration A2 (4 ml L-1) contributed to achieving the best results for all vegetative and flowering growth traits (plant height, number of leaves, vegetative dry weight, number of offsprings, leaf content of chlorophyll, total carbohydrates content of leaves, number of flowers, flower fresh weight, flower diameter, flower peduncle length), they were (13.65 cm, 34.64 leaf plant-1, 6.38 g, 7.72 offspring plant-1, 10.94 mg g-1, 7.44%, 5.56 flower plant-1, 2.26 g, 6.08 cm and 9.75 cm), respectively. A Spraying with nano stimulator (Proteck CalBor) achieved significant effect, especially B2 (1 ml L-1) concentration, that gave the highest values for the traits (plant height, vegetative dry weight, number of off springs, leaf content of chlorophyll, total carbohydrates content of leaves, number of flowers, flower fresh weight and flower diameter), they were (13.38 cm, 6.47 g, 7.48 offspring plant-1, 10.61 mg g-1, 7.49%, 5.40 flower plant-1, 2.41 g and 6.40 cm), respectively.

An experiment was conducted in Al-Ramadi city/ Al-Anbar province during the growing seasons 2009 and 2010 to investigate the effect of foliar spray with Yeast suspension, Licorice roots extract and Amino Quelant-K compound on some growth and yield traits of Black Hamburg grape cv, trained as arbors, Winter pruning was performed at the middle of January for both seasons by leaving 8 canes, each contains 15 buds, Also, a few spurs of 2 buds were left a renewal spurs, Study factors were spraying three concentrations (0, 5 and 10 g/l) , (0, 2 and 4 g/l) and (0, 2 and 4 ml/l) of Yeast suspension, Licorice roots extract and Amino Quelant-K, respectively, Treatment applications were performed at three times, the first was two weeks before flowering, the second was within a week after fruit set, meanwhile the third was after three weeks from the second one, Treatments were distributed in Randomized Completely Block Design (RCBD) a factorial experiment with three replicates, Each vine represent a single experimental unit, therefore 81 vines were involved in this study.Results revealed that clusters no, per vine was significantly affected by spraying Yeast suspension and Amino Quelant-K only in the second season, as the treatments 10 g/l and 4 ml/l of Yeast suspension and Amino Quelant-K respectively gave the highest number of clusters 51,19 and 50,04 cluster/vine compared with the control treatments (0 g/l and 0 ml/l of Yeast suspension and Amino Quelant-k, respectively) which gave the minimum number of cluster/vine (47,85, 47,67 cluster/vine, respectively), Fertility coefficient was affected by study factors in the second season, as the treatments 10 g/l, 4 g/l or 4 ml/l of Yeast suspension, Licorice roots extract and Amino Quelant-K, respectively showed the highest values of 1,24, 1,20 and 1,22 respectively, Treatments application were significantly affected plant leaf area, leaf content of chlorophyll and cane content of nitrogen and carbohydrate.
