Efek Residu Media Tanam dengan Penambahan Kompos Secara Berulang Terhadap Pertumbuhan dan Serapan Hara Nitrogen Tanaman Kailan

This study aims to determine the potential of planting media residues from rice crop in second period which were given input a mixture kiapu compost and straw with various compositions indicator plant used was kailan belongs vegetable group has fairly high nutritional value. The randomized block design treatments consisting 5 mixtures 2 comparison treatments, namely pearl NPK fertilizer treatment control so as follows; M0 : control, M1 100% kiapu, M2 75% + 25% straw, M3 50% M4 M5 M6 NPK. results showed that repeated application able give positive residual effect it could increase growth, yield N uptake plants. length due addition ranged 1.96% 22.79%, leaf area 11.28% 75.63% total fresh weight 28.85% 59.94%. significantly increased root uptake, canopy compared ranging 223.67% 283.36% at 175.03% 232.47% 194, 43% 241.63% on
