Respon Pertumbuhan Dan Hasil Tanaman Pakcoy (Brassica Rapa L.) Terhadap Aplikasi Pupuk Majemuk NPK Dan Micronutrien Growmore

Abstract

Pakcoy ( Brassica rapa L.) is a vegetable that is favored by the people of Indonesia and is needed all the time. Pakcoy cultivation with a hydroponic system is expected to increase the quality and quantity of pakcoy plant yields, however. The purpose of this experiment is to determine the best combination of fertilizers between the application of macro and micro elements of NPK compound fertilizer and Micronutrient Growmore. The experiment was carried out from June to July 2021 in Turen District, Malang. The experiment used a factorial completely randomized design with 2 factors and was repeated three times. The first factor is the concentration of NPK fertilizer consisting of 3 levels, namely P1, P2 and P3. The second factor is the concentration of Micronutrient Growmore Solube Mix fertilizer consisting of 3 levels, namely M0, M1, M2. Plant growth and yield were assessed from the variables of plant height, number of leaves, average leaf area, wet weight of crown, dry weight of crown, wet weight of roots and dry weight of roots. All observational variables were analyzed using the F test, and differences in each treatment and/or interactions between treatments were tested using Duncan's Multiple Range Test with a confidence level of 95 percent. The results obtained indicate that there is a very significant interaction between the application of NPK Fertilizer and Growmore Solube Micromix Fertilizer on plant height. The combination of NPK fertilizer with a concentration of 758 ppmm and Micronutrient Growmore 50 ppm gave the best results at plant height (17.97 cm). The application of NPK fertilizer with a concentration of 553 ppm tends to give better results than other treatments. Meanwhile, the concentration of 50 ppm Growmore micronutrient fertilizer tends to give better results than other treatments.
