مطالعه تاثیر مقادیر مختلف کود دای امونیم فاسفیت بالای حاصل گندم بهاری در شرایط اقلیمی کابل

Abstract (in English)

Wheat (Triticum aestivum L.) is an important food crop of the cold season and is considered one of the most significant food crops worldwide. The objective of this study was to determine the appropriate amount of diammonium phosphate (DAP) fertilizer on yield and agronomic characteristics of spring wheat under the climatic conditions of Kabul.

In this study, five different treatments (application rates) of DAP fertilizer were used: 0, 30, 60, 90, and 120 kg per hectare. The research was conducted during the years 2018 and 2019 at the research farm of the Faculty of Agriculture, Kabul University, and the botanical garden area. A Randomized Complete Block Design with three replications was used in the experiment.The results of this study showed that the application of DAP fertilizer had a significant impact on plant height, number of tillers, number of spikes, 1000-grain weight, and yield. The highest plant height (84.5 cm) was observed in the fifth treatment (120 kg/ha), while the lowest plant height (66.5 cm) was recorded in the control treatment. According to the results, the highest number of tillers (512) was obtained in the fifth treatment (120 kg/ha), whereas the lowest number of tillers was observed in the control treatment. Similarly, the highest 1000-grain weight (40 g) was recorded in the fifth treatment, while the lowest (34 g) was obtained from the zero-fertilizer treatment.
