The research was carried out at the protected cultivation department in Zakho Technical Institute, Dohuk Polytechnic University, Kurdistan region of Iraq during growing season 2021-2022 aiming to investigate the effect of foliar application of humic acid and seaweed extract each at concentrations (0, 2, and 4) ml.L-1 and soil addition of organic fertilizer (animal manure) at three rates (0, 5, and 10) ton.ha-1 on yield quality of broccoli cultivar (Agassirz) grown in plastic house. The experiment was designed following a randomized complete block design (RCBD) with three replicates. The earned results showed that the humic acid, seaweed extract, and organic manure, either individually or interacted, caused a prominent amelioration in the head qualitative traits such as Chlorophyll content (SPAD), Total soluble solids (TSS %), Ascorbic acid (%), Vitamin B1 (µg. L-1), and Total carotene (vitamin A) mg. L-1 as compared with control. The ever-highest values were obtainable from the treatment: humic acid at (4) ml. L-1 + seaweed extract at (4) ml. L 1 + organic fertilizer at (10) tons. donum-1 , which was superior to control and other treatments. The foliar application of humic acid and seaweed extract at a concentration of 4 ml. L-1 and soil addition of organic manure at level 10 tons. donum-1 is recommended for the organic production of broccoli cultivar (Agassirz).

Two-successive greenhouse experiments were conducted at the protected cultivation department in Zakho Technical Institute, Dohuk Polytechnic University, Kurdistan region of Iraq during the seasons of 2021-2022 and 2021-2022 to inspect the growth and yield response of broccoli cultivar (Agassirz) to foliar application of humic acid and seaweed extract at concentration of 0, 2, and 4 ml.L-1 for the both and using of organic fertilizer (animal manure) at three levels 0, 5, and 10 ton.ha-1. The treatments were organized in a randomized complete block design (RCBD) with three replicates. The obtained data revealed that the foliar application of humic acid and seaweed extract at concentration of 4 ml.L-1 and organic manure of 10 ton.donum-1 resulted in significant increase in vegetative traits of plant height (cm), number of leaves.plant-1, and number of head per plant and yield attributes of head weight (g), head dry matter (%), and yield (kg.m2), Whereas the humic and seaweed at concentration (2) ml.L-1 and organic manure applied at 10) ton.donum-1 importantly affected the fresh weight of vegetative growth. The topmost ever values were produced from the triple treatment; humic acid at (4) ml.L-1 ) + seaweed at (4) ml.L-1 + organic fertilizer at (10) ton.donum-1 in comparison with control and other doses.

his field study relied on collecting data related to the actual number of working hours of the power generating stations and their requirements from the fuel and the amount of the carbon dioxide emitted from these power plants because of burning diesel that contaminates our environment.

n spite of the scientific development and the continuous technological progress in all different fields, the economic prosperity in many societies has increased. But at the same time has negatively affected health and the environment as a whole due to different cases of pollution that raised from caused by industrial progress, and visual pollution is one of those types of pollution, and therefore must be seriously taken into consideration. So visual pollution is an aesthetic issue referring to the impacts of pollution that impair one’s ability to enjoy a vista or view. The term of visual pollution is also given to unattractive and man-made visual elements of vista, a landscape or any other things that make a person not to feel comfortable to look at. The purpose of this study was to identify repercussion of visual pollution and its influenceon public psychological health of some people in Duhok Centre and suburbs and also Zakho-Duhok Road. The results showed us from this study after presenting a group of photographs related to some cases of visual pollution on 500 people from of different age consisted of group of females and males during nine months from August 2017 to May 2018 from the Centre of Duhok and its Suburbs and the road linking the City of Zakho and Duhok that there was a discrepancy in the cases of Psychological discomfort for those people who were questioned resulting from looking at that image related to visual pollution and lead to the occurrence of some cases of Psychological illnesses. The good planning and managing is neglected by Government adding the lack of awareness about reducing the visual pollution and other types of pollution on a daily basis and working in harmony with a clean environment through activating and enforcing environmental protection laws.
