This study was conducted to investigate the effects of organic and chemical fertilizers (diammonium phosphate, DAP) on by physiological development of two cotton (Gossypium hirsutum L.) varieties grown under non-saline and saline soil conditions. It was carried out in 2019 at plant research laboratory of Vocational School Technical Sciences in Harran University, Turkey. Chlorophyll content, plant height (cm), root length (cm), fresh root weight (g), dry plant weight (g) and dry root weight (g) of Candia and Lima cotton varieties were determined to evaluate the effects of fertilizers. The layout of the pot experiment was randomized block with three replications. In non-saline soil; the lowest chlorophyll value (17.83) was recorded for the control, while the highest chlorophyll value (32.64) was obtained under the chemical fertilizer (DAP) treatment. In saline soil; the lowest chlorophyll value (20.33) was obtained in chemical fertilizer treatment, and the highest chlorophyll value (24.11) was determined from vermicompost treatment. The lowest plant height (27.83 cm) in non-saline soil was measured in chemical fertilizer application, while the highest plant height (33.00 cm) was recorded in cattle manure application. The shortest root length (13.66 cm) in non-saline soil was obtained from the control, and the highest root length (16.00 cm) was measured in chemical fertilizer. [ABSTRACT FROM AUTHOR] |
