Application of Coffee Grounds Organic Fertilizer on The Growth and Production of Cucumber Plants (Cucumis sativus L)

Cucumis sativus L, commonly known as cucumber, is a creeping vine plant and a member of the Cucurbitaceae family known for producing fruit-bearing vegetables. Cucumis sativus plants originate in the Asian continent, specifically in North and South Asia. The primary objective of this study is to investigate the development and yield of cucumber plants, focusing particularly on the impact of varying doses of organic fertilizer derived from liquid coffee grounds. Specifically, the study seeks to assess the effects of these treatments on plant height, time to flowering, time to harvest, and the weight of the fruit produced by cucumber plants. This study was conducted within the idyllic housing complex from March to May 2024. The research used a factorial randomized block design (RAK) with a single factor. The dosage parameters for coffee grounds fertilizer are as follows: P0 serves as the control group, P1 involves a dosage of 25 ml per plant, P2 utilizes a dosage of 50 ml per plant, and P3 applies a dosage of 75 ml per plant. The findings indicated that the various fertilizer treatments had a noteworthy impact on plant height, flowering age, harvest time, and fruit weight, suggesting a significant interaction between the two variables. Applying 75 ml of coffee grounds fertilizer per cucumber plant yields the best outcomes in promoting increased plant height, earlier flowering, shortened harvest time, and greater fruit weight in cucumber plants.
