A field experiment was carried out in the Horticultural Station at the department of Horticulture and Landscape, Tikrit University, during fall of 2023. The experiment studied the chemical response of chrysanthemum plants to organic materials consisting of 1:2 biochar and vermicompost (O) (0, 2, 4, or 6 %) and amino acid tryptophan (A) sprayed at levels (0, 0.25, 0.50, or 0.75 mg L-1). The results showed that there were significant effects of the two factors on the active ingredient Kaempferol. There was significant superiority of treatments T13, T14, T15 and T16 ( 6% of the mix). These treatments recorded the highest values of Kaempferol ( 35.44, 35.60, 35.40 and 35.22 mg L-1 respectively). Active ingredient, apigenin was significantly superior under the treatments T13, T14, T15 and T16 which received 6% of the mix. These treatments recorded the highest values (18.40, 18.22, 18.60 and 18.32 mg L-1, respectively) of this parameter. The plant height and number of branches were superior (20.08 cm, 15.75 branches) under the treatment O3 organic mix 6%. Interaction of the two factors was significantly superior in Kaempferol at the treatment T14 ( 6% organic mix with 0.25 mg tryptophan). The treatment recorded the highest value (35.60 mg. L-1). On the other hand, apigenin was significantly superior (18.60 mg. L-1 ) at treatment T15 (6% organic mix with 0. 50 mg. L-1 of tryptophan). Plant height was the significantly superior (21.75 cm) under the interaction treatment of O3A1. However, number of branches was significantly superior at the interaction treatments O3A0, O3A1, O3A2 and O3A3. They recorded 16.33, 16.33, 15.33 and 15 branch plant-1 respectively.

This study was carried out at Grdarasha field /Collage of Agricultural Engineering Science during 2023-2024. A factorial experiment based on randomized complete block design (RCBD), with three replicates, sowing dates (December 23th, 2023, January 17th, 2024 and February 11th, 2024), and three varieties of chickpea (Rafidain, Gab3 and TH85) were implemented. Gab3 produced the highest rates of plant height and no. of branches plant-1. The maximum rates of plant height were found in sowing at December 23th, the no. of branches plant-1 at sowing on February 11th and fresh pods plant-1 at January 17th. From the interaction between varieties and sowing dates was recorded the highest plant by Gab3 at December 23th and maximum no. of branches was recorded by Gab3 at sowing February 11th and no significant effect were recorded for other parameters. Weight of 100 seed produced the highest rate for Gab3 in physiological maturity and no. of seed pod-1 recorded by TH85 in full maturity stage. At sowing on December 23th produced the highest weight of 100 seed while, on January 17th gave the maximum rate of no. of seed pod- in both stages. The interaction between treatments most of parameters recorded the maximum rate by Gab3 at December 23th in physiological maturity and by TH85 at January 17th in full maturity. TH85 surpassed all varieties in the protein percentage and protein yield in both harvesting stages and these parameters gave different rates between sowing dates, also with interaction between treatments

A field experiment was conducted at the Research Station of the Field Crop Department College of Agriculture – Tikrit University, Saladin Governorate for the winter season 2022-2023 to study the effect of spraying at different levels of concentrations of salicylic acid and planting at various distances of Oat crops on some of the characteristics of Physiological and vegetative growth and yield. The experiment was carried out using a factorial random complete block design with three replicants in two factors, the first is spraying the salicylic growth regulator with three concentrations (0, 75, and 150) mg L-1. The second factor included distances between the planting rows (10 and 20 cm), the results showed an improvement in the level of concentration of salicylic 100 mg L-1 Compared with the rest of the salicylic concentration levels in the quality of duration of dry matter production (Biomass duration) and the absolute growth rate, the number of grains in panicle and the weight of a thousand oats grain trait, the distance (spacing) factor between the planting rows 20 cm improved compared with 10 cm planting spaces in all qualities studied in the experiment. As for the Interaction between the two factors of the experiment, the concentration recorded 100 mg L -1 and the distance between the planting rows was 20 cm high significant differences from the rest concentration levels of the regulator (salicylic) and row planting distances

This study was conducted in two seasons (2020-2021) and (2021-2022). First year (45) single plants and (45) samples (variety) with three replications were studied which they collected from (45) bread wheat field farmers under rain-fed condition. In the second year (12) varieties planted in Randomized Complete Block Design (R.C.B.D.) by three replications in Directorate of Agriculture Research-Erbil. First year result showed that most lines had higher yield and yield components than the standard verities, and (L42) had outperformed than other lines. Second year results showed variety (Hewlir 4) had outperformed than all other varieties in most of the traits, it obtained high yield and thousand grain weight by (16.9 g and 30.9 g) respectively. There was high phenotypic and genotypic correlation between yield/plant and thousand grain weight, seed/spike, grain per plant, and harvest index. High heritability (98 and 97) and high expected genetic advance (57 and 39) found in yield/plant and thousand grain weight respectively

The genetic diversity is agriculturally very interesting to improve the crops using breeding methods. Therefore, the growth inputs possess vital role to extract latent power of genetic diversity in given crops. So, A field trial was conducted out in Alhabaniyah district, Anbar province, Iraq on two points meteors of lat 33.3910°N long 43.5992°E and lat 33.3996°N long 43.5578°E. Where, the objectives included assessing some growth and yield traits of five roselle varieties viz., Red Hit, Oreib, Aswan, Black Hit, Sudan-3 under two types of fertilizers, the organic is bat guano and another one is diammonium phosphate (DAP). Treatments were distributed randomly using RCBD with triplicates. Results pointed that Black Hit was superior in plant height of 191.89 cm, vegetative fresh weight of 848.5 gm and seed yield of 402.7 Kg ha-1, while Aswan excelled in capsules number per plants of 143.9 capsule plant-1, capsule weight of 486.66 gm. the genetic material was variant as its performance was various. Therefore, this diversity could be embedded in breeding project to improve this crop. Deep researches are required to evaluate the impacts of organic nutrition on calyx production, early flowering and nutrients. Such information will assist to maximize the urbanized proximity to fresh ethnic crops. Indigenous nutritional plants such as Roselle could be served as a modelling crop for certain ethno-crops when they are transitted to cash crops
