Pengaruh Pemberian Pupuk Kandang Sapi Terhadap Serapan Kalium Tanaman Bawang Merah (Allium Ascalonicum L) Pada Entisols Sidera

ABSTRACT

This research was conducted from November 2019 to March in the Greenhouse of the Faculty of Agriculture and soil and plant analysis was carried out at the Soil Science Laboratory, Faculty of Agriculture, Tadulako University, Palu, Central Sulawesi. With the location of soil sampling in Sidera Village, Biromaru District, Sigi Regency, Central Sulawesi Province. This research was arranged in a randomized block design (RBD) with 6 treatments and repeated 4 times so that 24 experimental units were obtained. 6 experimental doses of the treatments were: Control (without giving cow manure): Cow manure with a dose of 5 tons ha-1 : Cow manure with a dose of 10 tonnes ha-1: cow manure at a dose of 15 tonnes ha-1: Cow manure at a dose of 20 tonnes ha-1: Cow manure at a dose of 25 tonnes ha-1: The results showed that cow manure at a dose of 10 ton ha-1 can increase Ph by 6.298% C-organic by 2.55%, K-available by 0.82 g, K plant tissue by 0.91.50%, and onion plant potassium absorption red by 6,3758%.

Key Word: Cow Manure, Potassium uptake, Shallots and Sidera Entisols

ABSTRAK
Penelitian ini dilaksanakan pada bulan November 2019 sampai bulan maret di Green House Fakultas Pertanian dan untuk analisis tanah dan tanaman dilakukan di Laboratorium Ilmu Tanah, Fakultas Pertanian, Universitas Tadulako, Palu Sulawesi Tengah. Dengan lokasi pengambilan sampel tanah di Desa Sidera, Kecamatan Biromaru, Kabupaten Sigi, Provinsi Sulawesi Tengah. Penelitian ini disusun dalam rancangan Acak Kelompok (RAK) dengan 6 taraf perlakuan dan diulang sebanyak 4 kali sehingga didapatkan 24 satuan percobaan 6 taraf dosis perlakuan tersebut antara lain: Kontrol (Tanpa pemberian pupuk kandang sapi ): Pupuk kandang sapi dengan dosis 5 ton ha-1 : Pupuk kandang sapi dengan dosis 10 ton ha-1: pupuk kandang sapi dengan dosis 15 ton ha-1: Pupuk kandang sapi dengan dosis 20 ton ha-1: Pupuk kandang sapi dengan dosis 25 ton ha-1: Hasil penelitian menunjukkan bahwa pemberian pupuk kandang sapi dengan dosis 10 ton ha-1 dapat meningkatkan Ph sebesar 6,298% C-organik sebesar 2,55%, K-tersedia sebesar 0,82 g, K jaringan tanaman sebesar 0,91,50%, dan serapan kalium tanaman bawang merah sebesar 6,3758%.
