Growth Response Of Mustard Green (Brassica juncea L.) Because Of Giving Cow Compost And Mikoriza Fertilizer Dosages

Mustard green (Brassica juncea L.) is leafy vegetable with subtropical climate, but this plant is able to adapt well on tropical climate that it suitable to be planted and growth in Indonesia. Formulation of problem in this study is to lessen the use of chemistry fertilizer in fertilization on plant especially mustard green (Brassica juncea L.). This study is aimed to review growth response of mustard green (Brassica juncea L.) because giving dosage of cow compost and mikoriza fertilizer dosages. This study used randomized block design (RAK) arranged in split plot with 2 factors. The first factor as main block of cow compost dosage consists of three level, they are 2,5 ton/ha, 5 ton/ha and 10 ton/ha. The second factor is offspring block, it is mikoriza dosage that consists of three levels, they are 1 tablet/plant, 2 tablets/plant and 3 tablet/plant for each is repeated 3 times. Observed variables are plant height, the number of leaves, leaf wide, fresh weight and dried weight of plant, fresh and dried weight, fresh and dried ratio of root weight and dried crown weight. The result of this study shows that there is no interaction between giving cow compost and mikoriza dosage toward mustard green height, fresh weight and dried weight, fresh and dried ratio of root weight and dried crown weight, but separately dosing cow manure 2.5 ton/ha can increase broad leaf mustard plants at 2 weeks after planting and dosage as well as mikoriza 1 tablet/plants and 2 tablets/plant has been able to increase leaf area from age 2 weeks after planting.
