ABSTRACT


This research was conducted with the aim to determine the application of various NPK fertilizers with a combination of cow manure on the growth and yield of Cilembu varieties of sweet potatoes. This research was carried out in Pelenggien Hamlet, Antirogo Village, Sumbersari District, Jember Regency, East Java Province. The timing of the research was carried out in November 2017 until March 2018. The research used factorial 2-RB Randomized Design (RBD) method. The first factor was the type of NPK fertilizer (P): giving NPK Mutiara fertilizer (P1), giving NPK Phonska fertilizer (P2), giving NPK Mahkota fertilizer (P3). The second factor is the dosing of cow manure (K): giving cow manure 20 tons / ha (K1), giving cow manure 25 tons / ha (K2), giving cow manure 30 tons / ha (K3). The results showed that the administration of cow manure had a significantly different effect on the diameter of the sample tuber with the best dose of 25 tons / ha (K2) of 12.64 m, 30 tons / ha (K3) of 12.62 m, and 20 tons / ha (K1) of 10.94 m. And the interaction of NPK fertilizer and cow manure gave a very significant different effect on the length of the main stem of sweet potato plant 49 HST with the best treatment of P1K3 (pearl fertilizer and cow manure 30 tons / ha) of 187,876 m. The application of pearl, phonska, and crown NPK fertilizers did not give a significant effect on the weight of the planting tubers and plots.

PenelitianinidilakukandengantujuanuntukmengetahuiAplikasi Berbagai Pupuk NPK Dengan Kombinasi Pupuk Kandang Sapi Terhadap Pertumbuhan Dan Hasil Panen Ubi Jalar Varietas Cilembu. Penelitianinidilaksanakandi Dusun Pelenggien Desa Antirogo Kecamatan Sumbersari Kabupaten Jember, Provinsi Jawa Timur. Waktupelaksanaanpenelitiandilakukanpada bulan November 2017 sampai dengan bulan Maret 2018. Penelitian menggunakanmetode Rancangan Acak Kelompok (RAK) 2 faktorial. Faktor pertama pemberian jenis pupuk NPK (P): pemberian pupuk NPK Mutiara (P1), pemberian pupuk NPK Phonska (P2), pemberian pupuk NPK Mahkota (P3). Faktor kedua pemberian dosis pupuk kandang sapi (K): pemberian pupuk kandang sapi 20 ton/ha (K1), pemberian pupuk kandang sapi 25 ton/ha (K2), pemberian pupuk kandang sapi 30 ton/ha (K3).Hasil penelitian menunjukkan bahwa pemberian pupuk kandang sapi memberi pengaruh berbeda nyata terhadap diameter umbi persampel dengan dosis terbaik 25 ton/ha (K2) sebesar 12,64 m, 30 ton/ha (K3) sebesar 12,62 m, dan 20 ton/ha (K1) sebesar 10,94 m. Dan interaksi pupuk NPK dan Pupuk kandang sapi memberi pengaruh berbeda sangat nyata terhadap panjang batang utama tanaman ubi jalar 49 HST dengan perlakuan terbaik P1K3 (pupuk mutiara dan pupuk kandang sapi 30 ton/ha) sebesar 187,876 m. Pemberian pupuk NPK jenis mutiara, phonska, dan mahkota tidak memberikan pengaruh beda nyata terhadap berat umbi pertanaman maupun perplot.
