أثر المناخ في تحديد الأنماط الزراعية (النباتية) في ناحية قره تبه

Abstract

The study showed that the arable area amounted to(213,675)dunums, representing (67.1%)of the total area .The non-arable area amounted to(105,075)dunums, representing(32.9%)of the total area. The public benefit area amounted to(31,284) dunums, representing(9.8%)of the total area of the district, which amounts to (318,750)dunums. Climatic data revealed that the climatic requirements for plants, including rainfall, temperature, sunlight, humidity, and wind, are met, appropriate, and achieved in the study area. The study showed that the area invested in the cultivation of cereal crops ranked first with a percentage of (84.6%) of the total area of cultivation of agricultural types invested for the year(2023),followed in second place by the vegetable crops pattern with a percentage of(7.2%), then the horticultural crops pattern with a percentage of(5.6%),then the industrial crops pattern in fourth place with a percentage of(1.8%),and the fodder cultivation pattern came in fifth and last place with a percentage of(0.8%),while the highest production was for the horticultural crops pattern with a percentage of (91.87%) and the production quantity was (89,000 tons) of the total production of agricultural crop types in the study area, which amounted to (96,869tons).The cultivation of large areas with all types of agricultural crops and their large productivity of(96,869tons) indicates that the climate has a great impact in determining the agricultural(plant) patterns in the Qara Tepe district. Therefore, it became clear from the climate data that the rainfall is characterized by its small quantities and fluctuations, in addition to other climate influences such as wind, evaporation and relative humidity, which made the study area dependent on irrigation water, as the rain-fed lands that depend on rain amount to (109,475) dunums and a percentage of (51.2%) of the area suitable for agriculture.
