Fi`liyah (2016) Pengaruh Pemberian Pupuk Kcl Terhadap N , P, K Tanah Dan Serapan Tanaman Pada Inceptisols Untuk Tanaman Jagung Di Situ Hilir, Cibungbulang, Bogor. Sarjana thesis, Universitas Brawijaya.
Abstract
Pupuk KCl merupakan pupuk anorganik yang dibutuhkan tanaman jagung dalam proses fotosintesis, memacu pertumbuhan tanaman pada fase vegetatif, memperbaiki mutu hasil yang berupa bunga dan buah. Unsur hara yang terdapat pada pupuk KCl yaitu unsur hara K merupakan unsur hara makro. Peningkatan produktivitas tanaman jagung dipengaruhi peranan pupuk terutama hara makro N, P, dan K yang dibutuhkan dalam jumlah besar di dalam tanah. Tujuan dalam penelitian ini yaitu mengetahui pengaruh pupuk KCl terhadap pertumbuhan dan hasil produksi tanaman jagung, menentukan dosis optimum pupuk KCl terahadap hasil tanaman jagung, mengetahui pengaruh pupuk KCl terhadap kandungan hara NPK dalam tanah dan serapannya dalam tanaman. Penelitian ini dilaksanakan pada bulan Oktober 2014 hingga April 2015 yang bertempat di desa Situ Ilir Cibungbulang Bogor. Penelitian dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) dengan delapan perlakuan yang masing-masing diulang tiga kali. 1)kontrol , 2)KCl 100 (kanada), 3) KCl 25 (rusia), 4)KCl 50 (rusia), 5)KCl 75(rusia), 6)KCl 100(rusia), 7)KCl 125(rusia), 8)KCl 150(rusia). Parameter pengamatan meliputi tinggi tanaman, jumlah daun, brangkasan basah, brangkasan kering, serapan NPK tanaman, residu NPK pada tanah yang analisis dilakukan saat pasca panen. Hasil penelitian menunjukkan bahwa pemberian pupuk KCl dengan dosis yang berbeda berpengaruh nyata dalam pertumbuhan tanaman jagung. Selain itu berpengaruh pada produksi tanaman jagung pada perlakuan P5 dengan produksi 6,97 ton/ha pada pipilan kering. Pengaruh pemberian pupuk KCl dengan dosis yang berbeda juga berpengaruh pada serapan tanaman. Serapan N tertinggi pada perlakuan P1 34.68 kg/ha, serapan P tertinggi pada perlakuan P7 8.58 kg/ha, dan serapan K tertinggi pada perlakuan P7 23.38 kg/ha. Pengaruh pada tanah dengan dosis yang berbeda perlakuan pupuk KCl menghasilkan Residu N yang sangat rendah dengan nilai 0.0769 % hingga 0.0821%, Residu P yang sangat tinggi dengan nilai 64.24 ppm hingga 104.44 ppm, Residu K yang sangat tinggi dengan nilai 0.261% hingga 0.326%.
English Abstract
KCl’s Fertilizer constitute needed anorganic fertilizer maize in processes photosynthesis, touch up crop plant on vegetative phase, restore produce quality that as flower and fruit. Nutrient which are contained on KCl fertilizer that is nutrient K constitute macro nutrient. Productivity enhacement maize be affected role a fertilizer mainly N P K macro nutrien5 that be required in the amount of substantial inside the soil. Purpose in this research that is understand effect KCl fertilizer about contents nutrient npk in the soil and uptake in he plant, determining fertilizer optimum dose KCl to maize, understand effect KCl fertilizer about growing and production result maize The research was conducted in Situ Ilir Village, Cibungbulang, Bogor District on October 2014 to April 2015. The study was conducted using a randomized block design with 8 treatments and each treatment was replicated 3 times. 1) Control; 2) KCl 100 (Canada); 3) KCl 25 (Russia); 4) KCl 50 (Russia); 5) KCl 75 (Russia); 6) KCl 100 (Russia); 7) KCl 125 (Russia); 8) KCl 150 (Russia). Observation parameters of height crop, total leaves, fresh weight of crop and dry weight of crop. Soil analyzes done after harvest includes N P K crop uptake and N P K soil residue. Show research result that application kcl fertilizer with dosed significant effect different in growing a corn. In addition to the effect on production of maize on treatment P5 with production 6,97 ton/ha on dry seed. Application influence kcl fertilizer with dosed different one also ascendant on plant. On uptake N very hight on P1 34,68 kg/ha, on uptake P very hight on P7 8,58 kg/ha, on uptake K very hight on P7 23,38 kg/ha. Effect on soil with dosed different on treatment KCl fertilizer result residu N very low with value 0.0769 % until 0.0821 %, residu P very hight with value 64.24 ppm until 104.44 ppm, residu K very hight with value 0.261 % until 0.326%.
