Pengaruh Dosis Vermikompos terhadap Pertumbuhan dan Produksi Tiga Varietas Caisim ( Brassica juncea L.)

Abstract

The use of superior varieties and good fertilization is needed to increase plant growth. This research aims to determine the effect of vermicompost dosage on the growth and production of three varieties of green mustard. This research was carried out at coordinates 3°29'27"N 98°39'45"E with an altitude of ± 60 meters above sea level using polybags, from July 2024 to August 2024. This research uses a Randomized Complete Block Design (RCBD). consists of 2 factors with 3 replications. The first factor was three green mustard varieties : Kumala, Shinta F1 and Tosakan. The second factor was dosage vermicompost with 4 levels : 0, 15, 30 and 45 tons/ha. Tosakan variety actually produces the highest plant height, Kumala variety actually produces the highest number of leaves. Vermicompost dosage of 45 tons/ha significantly resulted the highest plant height, number of leaves, shoot fresh weight, selling fresh weight, root fresh weight and harvest index. The interaction between the three varieties and vermicompost dosage had no significant effect on all observed parameters.
