Pengaruh Pemberian Pupuk Organik Solid dan Pemberian POC Limbah Cair Tahu Terhadap Pertumbuhan dan Produksi Tanaman Jagung Manis (Zea mays saccharata L)

Tujuan penelitian ini untuk memperoleh data pertumbuhan dan produksi tanaman jagung manis (Zea mays saccharata L). Dengan pengaplikasian pupuk organik solid dan pupuk organik cair tahu dengan dosis dan kosentrasi berbeda. Penelitian ini dilaksanakan di lahan percobaan fakultas pertanian universitas medan area yang berlakosasi dijalan PBSI no 1 Medan Estate . Penelitian dilaksanakan pada bulan Juni sampai bulan Desember 2018. Menggunakan acak kelompok (RAK) faktorial dengan dua ulangan. Faktor pertama yang diuji adalah dosis pupuk organik solid yaitu S0= tanpa pupuk organik solid S1= dengan dosis 20 ton/ha, S2= dengan dosis 30 ton/ha, S3= dengan dosis 40 ton/ha. Faktor kedua adalah konsentasi pupuk cair limbah tahu yaitu C0= tanpa pupuk cair limbah tahu C1= dengan konsentrasi 250 ml/liter air, C2= dengan konsentrasi 500 ml/liter air, C3= dengan konsentrasi 750 ml/liter air. Hasil penelitian menujukkan bahwa pemberian pupuk organik solid dengan perlakuan S3= 40 ton/ha berpengaruh nyata terhadap tinggi tanaman Berat tongkol Tanpa Klobot/sampel Berat Tongkol Tanpa Klobot/Plot dan pada pengaplikasian pupuk organik cair tahu berpengaruh tanya dengan perlakuan C1= 250 ml/liter air pada warna daun.The purpose of this study was to obtain data on growth and production of sweet corn plants (Zea mays saccharata L). With the application of organic fertilizers and organic fertilizers know with different doses and concentrations. This research was carried out on the experimental area of the university's faculty of agriculture which took place in the PBSI No. 1 estate field. The study was conducted in June to December 2018. Using factorial randomized groups (RBD) with two replications. The first factor that issued was S0 = solid organic fertilizer without S1 organic fertilizer = with a dose of 20 tons / ha, S2 = with a dose of 30 tons / ha, S3 = with a dose of 40 tons / ha. The second factor is the concentration of tofu liquid fertilizer C0 = without C1 liquid warse know fertilizer = with a concentration of 250 ml / liter of water, C2 = with a concentration of 500 ml / liter of water, C3 = with a concentration of 750 ml / liter of water. The results showed that what is meant by solid organic fertilizer with the implementation of S3 = 40 tons / ha means that it is real against the height of Cob plants without Klobot / sample Cob Weight without Klobot / Plot and in the application of tofu organic fertilizer that is questioned with the help of C1 = 250 ml / liter water on the color of the leaves
