EFEKTIFITAS PENGGUNAAN LIMBAH AIR CUCIAN BERAS DALAM MENGURANGI PENGGUNAAN PUPUK NPK MUTIARA TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN JAGUNG MANIS (Zea mays L.)

Zea mays L. is one of the food crops that people like because it has a lot nutritional content. In increasing growth and production plants, can be done by integrating rice washing water waste with inorganic fertilizers in order to minimize use chemical fertilizers. The purpose this study was determine effect using reducing pearl NPK on vegetative plants. This research carried out at Greenhouse Agrotechnology Study Program, Faculty Agriculture, Musamus University June - September 2022 cultivation scale polybaq. design used completely randomized (CRD) 7 treatments 3 replications, namely: K0 = Control; K1=rice without NPK; K2=rice water+25% K3=rice water+50% K4=rice water+75% K5 + 100% A6= pearl. Parameters observed were: plant height, number leaves, stem diameter, leaf area, cob weight, weight cob, rows seeds per ear, length, 100 seed weight. Observations were analyzed method variance. If there are significantly different treatments, then proceed BNT test 95% confidence level. results showed treatment had significant L.. Based data from analysis treating 50 % 75% Pearl increase generative corn plants so as 25% -50% recommended dose.
