Pengaruh pemberian pupuk NPK terhadap pertumbuhan dan hasil tanaman terung Galatik (Solanum melongena L.)

Abstract

This research used a Randomized Block Design (RAK) with 5 (five) treatments and 5 (five) replications, each replication consisted of 20 plants, so the number of plants studied was 500 plants. The number of samples observed in each experimental unit was 3 (three) plants. The treatments in this research were as follows: P0 = No NPK fertilizer, P1 = 100 kg/ha NPK fertilizer, equivalent to 60 g/plot, P2 = 200 kg/ha NPK fertilizer, equivalent to 120 g/plot, P3 = 300 kg/ha NPK fertilizer, equivalent to 180 g/plot, P4 = 400 kg/ha of NPK fertilizer, equivalent to 240 g/plot. Parameters observed in this study were plants height, number of branches, flowering age, number of fruit per plants, harvest age, fruit diameter, fruit weight per plants and fruit weight per plot. Applying NPK fertilizer has a good influence on plant growth and yield of Provita F1 eggplant. Applying of NPK fertilizer at a dose of 120 g/plot (P2) produces a plant height of 48.8 cm, number of branches 7.73, flowering age 30.47 dap, number of fruit per plant 3.49, harvest age 65 dap, fruit diameter 43.01 mm, fruit weight per plant 2.11 kg and fruit weight per plot 2.79 kg.
