Abstract

ABSTRAK Untuk mengetahui pengaruh pupuk majemuk terhadap hasil dan mutu tembakau virginia yang ditanam di tanah ringan, telah dilakukan penelitian di Desa Pengarang, Kecamatan Pujer, Kabupaten Bondowoso mulai bulan April sampai Nopember 2001. Penelitian ini menggunakan rancangan acak kelompok dengan tiga kali ulangan untuk menyusun perlakuan. Perlakuan yang dicoba adalah pupuk majemuk (PM) dengan dosis 5, 6, 7, 8 dan 9 butir pertanaman dibandingkan dengan PM (dosis masing-masing) dicampur dengan biokonsentrat. Sebagai perlakuan pembanding adalah paket pupuk rekomendasi, yaitu 200 ZA + 200 PN + 100 SP36 + 100 ZK. Hasil penelitian menunjukkan bahwa pemberian PM sebanyak 6 butir per tanaman (setara dengan 185 kg/ha atau 40 kg N/ha) menghasilkan daun basah tembakau sebanyak 11,34 ton/ha. Hasil daun basah tersebut tidak berbeda dengan hasil daun basah tertinggi (12,42 ton/ha) yang dihasilkan tanaman tembakau dengan paket dosis rekomendasi. Dosis pupuk majemuk juga memberikan nilai indeks mutu tertinggi (55,90) tidak berbeda pengaruhnya dengan pupuk rekomendasi. Pemberian pupuk rekomendasi menghasilkan tanaman tembakau yang berkadar N dan P jaringan tanaman tertinggi pada pengamatan umur tanaman 75 hari setelah tanam dan pada saat akhir panen. Kata kunci: Tembakau virginia, tanah ringan, pupuk, Kabupaten Bondowoso, Jawa Timur ABSTRACT Effect of compound fertilizer on yield and quality of virginia tobacco in light soil, Bondowoso, East Java Study to determine the effect of compound fertilizer on yield and quality of virginia tobacco was conducted in Pengarang, Pujer, Bondo- woso District, from April to November 2001. Factorial in randomized block design with three replicates was arranged to set the treatment consisting of two factors. The first factor of treatment consists of two variables, i.e. compound fertilizer (PK) and PK +bio-concentrate. The second factor was the rates of PK, i.e 5, 6, 7, 8, and 9 tablets per plant or equivalent to 185, 221, 258, 294 and 331 kg/ha. All the treatments were compared to recommended fertilizer to farmers (200 ZA + 200 PN + 100 SP36 + 100 ZK kg/ha). The results showed that 185 kg/ha PK gave the fresh tobacco yield of 11.34 tones/ha which was not significantly different with the highest fresh tobacco leave (12.42 tones/ha) produced by recommended fertilizer. Grade index value of tobacco produce by PK and recommended fertilizer was not significantly different. However, virginia tobacco with recommended fertilizer had the highest content of N and P in plant tissues which were observed at 75 days after planting and until the end of harvesting. Key words: Virginia tobacco, light soil, fertilizer, Bondowoso District, East Java
