The current study was conducted from February 2023 to August 2023 at a local farm in the Biology Department, College of Science, University of Zakho in the Kurdistan Region of Iraq. It aimed to examine the effects of drought and the application of salicylic and folic acid on some physiological parameters of two cotton (Gossypium hirsutum L.) cultivars (MAY 505 and MAY 455). For this reason, a randomized complete block design (RCBD) was used to assess the physiological aspects of the cotton plant. Both cotton cultivars were treated with salicylic acid (SA) at concentrations of 0, 1, and 2 mM, and folic acid (FA) at 0, 5, and 10 mM, separately and in combination, and subjected to three drought periods as (continuous irrigation (Ci), 10, and 15 days thirst). The results indicated that proline content was the highest in plants treated with (1 mM SA) at (33.75 µg/mg) in MAY 505 and (28.29 µg/mg) in MAY 455 under similar drought conditions. Further, plants sprayed with (5 mM FA) showed the highest chlorophyll content at (46.82 SPAD value) for MAY 505 and (50.77 SPAD value) for MAY 455. The application of (2 mM SA) scored the highest increase in P, K, and Mn, while the applied (10 mM FA) showed the highest increase in N and Cu. Cultivar MAY 505 was shown to be more responsive in addressing drought periods than MAY 455.

The Impact Of Biochar And Compost As A Soil Amendment On The Growth, Yield, And Chemical Composition Of Maize (Zea Mays): A Study On Two Different Land Uses

Soil health is the production base, and management allows manufacturers to work with the land. Healthy soil provides a clean environment and nutritious crop. The performance of the crop on alkaline-saline soil is incomplete due to poor nutrient management. Biochar and compost initiated distinctive biomass to improve soil health. Equally; limited studies were conducted on the co-application of biochar and compost produced from the same field of alkaline. Therefore; a pot experiment of two different soils i.e. banana cultivated fields (BCF) and Coastal fallow land (CFL) was conducted to estimate the effect of co-application of biochar and compost on the soil properties, growth, and yield attributes of Maize. Completely Randomized Design (CRD) with a total of 24 pots, filled with 15kg of soil, with four different treatments including control (Co), 1% Compost (C), 1% Biochar (B), and 1% Biochar + Compost (B+C), within three times replicate. Generally; study findings showed that 1%B+C has a significant (p<0.05) effect on the growth and yield followed by 1%C, 1%B, and Co. In the comparison of the alone 1%B and 1%C, 1%C performs better and more significantly (p<0.05) different compared to 1%biochar and control. Similarly; the availability of NPK, SOM%, and CEC of both BCF and CFL increased within co-application of 1% B+C, compared to 1%C, and 1%B. While; the increased order of the co-application was recorded as 1%B+C >1%B > 1%C and Co. Consequently, co-application of 1%B+C with fertilizer could be a suitable management approach to increased crop yield and improve soil health of the alkaline calcareous soil.

The main objective of this study is to identify the rural women’s knowledge in some environmental domains in Duhok Governorate, Kurdistan region of Iraq. Area random sampling was used to select the research sample which is (507) rural women. A questionnaire was designed to collect the research data, which is consisted of two parts, the independent variables and knowledge test consisted of (47) items distributed on four domains (Home waste management, Sustainable agriculture, Sustainable methods of using and conservation of forest, and Rural tourism). Experts and content validity were used to achieve the validity of the knowledge test, and Kurder-Richardson21 formula was used to measure the reliability of it, it is value was (0.777). The data was analyzed with SPSS program. The results showed that knowledge level of the respondents in all the studied environmental domains is medium tends to low. Home waste management domain ranked the first (=7.719). While rural tourism domain ranked the last (=4.888). The result also showed that there is significant correlation between the knowledge level of respondents and each of the following variables (Level of education, Satisfaction with services in the village, Agricultural information sources, and Cultural openness). While there is no significant correlation with :( Age, Material status, Current work, and Participation in family decision –making). The research included some conclusion and recommendations.
