Abstract
The study was conducted at the Ismailia
Station for Agricultural Researches, which is affiliated with the Agricultural
Research Centre in Giza, Egypt, during the winter seasons of (2021 and 2022).
The aim of this study is to evaluate the impact of exposing the seeds to a low
temperature (4 °C) before planting and treating the plants with spirulina
extract on the flowering process and cantaloupe yield (Milagro F1) grown in
greenhouse conditions with sandy soil. The experiment involved two factors. The
first factor was the number of days the seeds were cooled at 4 °C before
planting (0, 1, 2, or 3 days). The second factor was the application of
spirulina extract to the seedlings after the cotyledon leaves opened and after
15 days of cultivation (0, 1.5 ml, or 3 ml concentrated spirulina per liter of
water). The study used a factorial randomized complete block design within a
split plot system. The means were compared using the Duncan multiple range test
at a significance level of 5%. The characteristics of growth, flowering, yield,
and fruit quality were studied. The results showed that increasing the number
of cooling days as well as spraying spirulina extract till 1.5 ml/liter
resulted in the highest growth, flowering, and yield of the cantaloupe plant.
The greatest results were obtained by cooling the seeds for three days and
spraying with spirulina at 1.5 mL/L. Increasing the spirulina spray rate to 3
mL/L lowered the distinguishing features when compared to 1.5 mL/L. To
summarize, to improve cantaloupe flowering, growth, and yield with spirulina
alone, spraying at a defined time until 1.5 ml/liter extract is demand;
however, to improve by cooling seed alone, cooling seeds for 3 days before
transplanting at 4 C; and the maximum improvement obtained by interacting at
both levels from different two factors.
