Dosis Kebutuhan Hara untuk Produksi Sawi (Brassica juncea. L) menggunakan Sistem Hidroganik

Abstract

The research was describe fertilizer effectiveness based on the nutrient requirement of green mustard (Brassica juncea L.) production using hydroganic system of Sangkuriang catfish. This study aims to achieve the effectiveness of fertilization based on nutrient requirements for the production of 10 Ton/Ha - 40 Ton/Ha of green mustard (Brassica juncea L.) using the Sangkuriang catfish by hydroganic system. This study used a factorial split-plot design (SPD) with fertilizer treatment factors. The factors were the fertilizer of 5 levels, namely, P0= 0 gr/pot, P1= 1,36 gr/pot, P2= 2,73 gr/pot, P3= 4,08 gr/pot, P4= 5,45 gr/pot. The analysis was carried out after the application of the dose to green mustard in two different water sources (I0 and I1). The results showed that the combined application dosage of green mustard production of I1P3 (fertilizer dosage 4.08 gr/pot with a production target of 30 tonnes/Ha with Sangkuriang catfish source water) was the highest yield.
