Three rice varieties (Goura, Chakhao and Local) were grown during two seasons 2019-2020, aimed to assessment of different levels of spraying of phenylalanine on performance of the grain yield components in different rice varieties. The selected three varieties (sub plots) were grown under the influence of four levels of phenylalanine spraying (main plots), included amino acid treatments occupied the main plates 50, 100 and 150 mg.L-1 as well as the control treatment (spraying distilled water only), the experiment applied in split plots arrangements in RCBD with three replications. The results showed a significant superiority of the Goura genotype selected by giving the highest averages in plant height, total grains number per panicles, 1000 grains weight, grain yield, Biological yield, percentage of harvest index and tillers number plant, that reached to 118.47 cm, 144.25 grains.panicl-1, 23.44 g, 6.70 tons.hectare-1, 12.06 tons.hectare-1,54.82% and 18.40 tillers.plant-1 respectively, while the genotype significantly superior to Local Selected by giving the highest averages in the leaves content of total chlorophyll pigments SPAD, which amounted to 39.13 SPAD. The spraying of the amino acid phenylalanine at a concentration of 50 mg.l-1 was significantly superior by giving the highest averages in the indicators of vegetative growth, yield and its components.
Experiment was conducted during summer season of 2021 to study the effect of foliar applications of Phenylalanine (Phe), Jasmonic acid (JA), Biofertilizer (Bio) and their combinations (Phe+JA, Phe+Bio, JA+Bio, Phe+JA+Bio and control) on some growth, yield parameters and anthocyanin compounds on Roselle calyces Hibiscus sabdariffa L., The treatments were distributed on Randomized Completely Block Design in three replicates, means were compared according to the Least Significant Difference test (LSD) at probability level of 0.05. The results show that growth parameters (plant height, branches number, leave area and chlorophyll) and yield parameters (fruits number, fresh weight calyces, fresh yield calyces and dry yield calyces) were increased due by foliar application Phe+JA+Bio, while the combination treatment Phe+Bio gave significant effects on vitamin C, total anthocyanin, Gossypetin, Sabdartine, Hibescitine, Delphidine and Cyanidin of calyces reached at 201.5, 184.5, 29.3, 31.2, 57.4, 35.4, 27.8 (mg.100g) respectively.
The experiment was conducted in one of the special fields for the winter agricultural season 2020/2021 in Al-Qadisiyah province / Sumer-Al-Barakat sub-district, which is 17 km from the district, at 32.14 degrees north latitude and 44.99 degrees east longitude. To know the effect of spraying some nano-fertilizers and their combinations on the growth and yield of the fenugreek, the experiment was carried out according to a randomized complete block design with three replications. The experiment included 10 treatments (T1), the control treatment, spraying distilled water only, (T2) a balanced nano-NPK spraying at a concentration of 2 g L-1, (T3) adding NPK mineral fertilizer 200 kg ha-1, (T4) Spraying nano microelements 2 g L-1 + NPK mineral fertilizer, (T5) Spraying nano seaweed extract 2ml.L-1 + adding NPK mineral fertilizer, (T6) spraying nano NPK at a concentration of 2 g.L-1 + mineral NPK, (T7) Spraying nano micro-elements fertilizer at a concentration of 2 g L-1 + nano seaweed extract at a concentration of 2 ml L-1 + adding NPK mineral fertilizer, (T8) spraying nano micro-elements at a concentration of 2 g L-1 + nano NPK at a concentration of 2 g L-1 + adding NPK mineral fertilizer and (T9) spraying nano seaweed extract at a concentration of 2 ml L-1 + nano NPK at a concentration of 2 g L-1 + adding Mineral NPK fertilizer and (T10) spraying nano-micro elements 2 g. L-1 + nano seaweed extract 2 ml L-1 + NPK nano-concentration 2 g L-1 + adding NPK mineral fertilizer, the first spraying was done three times when the plants reached 6-8 leaves, the second and the third with an interval of 14 days between them. The results showed significantly excelled of plants treated with (T10) and the highest averages were achieved in the vegetative growth traits compared to the control treatment. It also produced the highest averages in all yield traits and its components, especially the fresh and dry leaf yield, and seed and oil yield, which amounted to 12.771, 1.442, 1.431, and 159.48 kg ha-1, respectively, compared with the control treatment, which produced 9.514, 1.163, 1.024 and 99.38 kg ha-1, respectively.

A field experiment was carried out at winter season of 2020-2021 in Babylon Governorate, region of Bernon, at 8 km north-east of Hilla town between 44.27 ° north and 36.32 ° east latitude, to study the effect of planting distance and Humic acid on growth, yield and antioxidant activity of petals and seeds of the safflower, the treatments were distributed in a factorial experiment with randomized completely block design (RCBD) with three replicates, the first factor was the distance between plants (10, 15 and 20 cm) and second was spraying Humic acid at concentrations (0, 125, 250 and 500 mg.l-1), data were collected and means were tested according to least significant difference test (LSD) at probability level 0.05. The results showed superiority significant of planting distance at 20 cm and spraying humic acid at concentration 500 mg.L-1 on growth and yield parameters, while plants distance at 10 cm excelled on plant height and content of petals and seeds of antioxidant activities. The results showed superiority significant at interaction treat 20 cm × 500 mg.L-1, it produced the highest rates in most considered qualities and yield of dry petals and seed yields were 79.658 and 2197.5 kg. ha-1, while interference treat 10 cm x 500 mg.L-1 produced the highest means on total phenolic compounds and total oxidative activity and scavenging free radicals reached 41.47, 212.7, 58.07, 38.72 and 33.59 mg.g-1 DW, 67.7 and 47.0% in petals and seeds respectively.
