Abstract

The study was conducted to determine the effect of combined mineral NPK and organic fertilization with humic acid on the vegetative and flowering characteristics of Squash plants. A field experiment was conducted during the 2020 and 2021 in Al Jabal Al Akhdar in the Al-Wasita area. A randomized complete block design split in three replications was used, as the experiment included 25 factorial treatments representing all possible combinations between the levels of the factors studied for both NPK complex. fertilizer (0, 45, 90, 135 and 180 kg/ha) and levels of humic fertilizer ( 0, 20, 40, 60 and 80 kg/ha. The results showed that the increase in the levels of mineral fertilizer led to significant differences in all the vegetative and floral traits response to the increase in the levels of NPK. The rate of 180 NPK kg/ha gave the highest values compared to the control treatment for all vegetative and floral traits The study showed that the increase in humic fertilizer rates from 0 kg/ha to 80 kg/ha was accompanied by a significant increase in vegetative growth and floral traits, The rate of 80 kg Humic/ha gave the highest significant values compared to the control treatment for all traits The results of the effect of the interaction between NPK and humic on the vegetative and floral traits indicated that there were clear significant differences, and that the best compatible treatment that gave the highest significant increase in both vegetative and floral traits was (180 NPK and 80 kg/ha humic.
