Respon Pertumbuhan dan Hasil Sawi Hijau Akibat Pemberian Pupuk Hayati dan NPK

Researchers and farmers always strive for balanced fertilization to increase yields of green caisim. The additional dose of organic fertilizer needs to be adjusted to the using of inorganic fertilizer dosages. So this research was carried out to determine the dosage of organic and inorganic fertilizers for these two types of fertilizer that affect the growth and yield of green caisim. The research was held from March to April 2023. The research location was in Batu City, East Java. First factor was the dose of biocomplex biofertilizer which consisted of: B0 = without biocomplex, B1 = 5 ton.ha^-1, B2 = 10 ton.ha^-1 and B3 = 15 ton.ha^-1. Second factor was the dose of NPK fertilizer which consists of: N0 = without NPK, N1 = 150 kg.ha^-1, and N2 = 300 kg.ha^-1. The two factors were arranged using a RBD factorial . Repeated 3 times. All observed data were analyzed using the 5% F test. If there is significant among treatments, treatment value means were tested in BNJ level of 5%. So the use of biocomplex fertilizer under 15 tons.ha^-1 and NPK fertilizer under 300 kg.ha^-1 are effective in increasing growth and yield of green caisim. Apart from that, it is possible to save costs for two types of fertilizer. So the use of 5 ton.ha^-1 and 10 ton.ha^-1 biocomplex fertilizer that added to 150 kg.ha^-1 are able to increase the growth and yield of green caisim.
