      Abstract
      Pertumbuhan sorgum yang optimal dapat dilakukan dengan pemberian dosis nitrogen yang tepat. Penelitian ini bertujuan untuk mengevaluasi perbedaan dosis nitrogen terhadap hasil pertumbuhan dan produktivitas tanaman sorgum. Pada 20 penelitian dari tahun 2006-2020 diperoleh 211 data perlakuan dan diinput dalam Microsoft Excel 2016. Data tersebut meliputi data pertumbuhan dan produksi yaitu umur panen, tinggi tanaman, jumlah daun, produksi bobot segar (BS), dan produksi bahan kering (BK). Kemudian data tersebut dianalisis menggunakan software IBM SPSS 26. Hasil penelitian menunjukkan bahwa penambahan dosis pupuk berpengaruh sangat nyata terhadap umur panen, peningkatan produksi bahan segar (p<0,01) dan penurunan produksi bahan kering secara nyata (p<0,01). tetapi tidak mempengaruhi jumlah daun dan tinggi tanaman (p>0,01).
       
      Optimal growth of sorghum can be done by giving the right dose of nitrogen. The aim of this study was to evaluate differences in nitrogen dosing on growth yield and productivity of sorghum plants. A total of 20 studies from 2006-2020 obtained 211 treatment data and recorded in Microsoft Excel 2016. The data includes growth and production data, namely harvest age, plant height, number of leaves, production of fresh weight (BS), and production of dry matter (BK). Then the data were analyzed using IBM SPSS 26 software. The results showed that the addition of fertilizer doses, increased production of fresh matter (p<0.01) and significantly decreased dry matter production (p<0.01). but did not affect the number of leaves and plant height (p>0.01).
