Abstract

Most of tobacco farmers in Madura cultivate tobacco var. Prancak-95, yet the response of the variety to NPK fertilizer had not been identified. The purpose of this study was to examine the effect of NPK fertilizer on growth, yield and quality of madura tobacco var. Prancak-95. The study was conducted on silty loam soil at Lecen-lecen village, Pakong sub district, Pamekasan District, from April to December 2015. Tobacco was planted on early of June 2015 with double row spacing of (130+35)/2 cm x 40 cm. The treatments were arranged using Randomized Block Design with 3 replications. The treatments were 9 combinations of three level of N fertilizer (40, 60, and 80 kg N/ha) and three level of K fertilizer (19, 60.5 and 102 kg K2O/ha), and farmer’s fertilizer package (40 kg N + 36 P + 25 kg K+ 5 tons manure per hectare) as a control treatments. The results showed that yield and quality of madura tobacco var. Prancak-95 was increased when the doses of N and K fertilizers were increased. NPK fertilizer with dosage of 60 kg N + 45 kg P2O5 + 102 kg K2O + 5 tons manure per hectare was enough to produce sliced dried leaf as much 1,168 kg/ha and crop index value of 110.1.Keywords: Nicotiana tabacum L., NPK fertilizers, madura tobacco AbstrakPenanaman tembakau Varietas Prancak-95 telah berkembang luas di Madura, tetapi responnya terhadap pemupukan NPK belum diketahui. Tujuan penelitian ini adalah untuk mengetahui pengaruh peningkatan dosis NPK terhadap pertumbuhan, hasil dan mutu tembakau madura varietas Prancak-95. Penelitian dilakukan pada tanah dengan tekstur lempung berdebu di Desa Lecen-lecen, Kecamatan Pakong, Kabupaten Pamekasan dari bulan April hingga Desember 2015. Tanam dilaksanakan pada awal Juni 2015 dengan jarak tanam ganda (130+35)/2 cm x 40 cm. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok dan diulang 3 kali. Perlakuan terdiri dari 9 kombinasi paket pupuk dengan 3 tingkat dosis N : 40, 60, dan 80 kg N/ha dan 3 tingkat dosis K : 19, 60,5 dan 102 kg K2O/ha, dengan kontrol paket pemupukan petani. Separuh dosis N sesuai perlakuan diberikan pada tanaman berumur 7 HST, sedangkan sisanya diaplikasikan saat tanaman berumur 21 HST. Hasil penelitian menunjukkan bahwa produksi dan mutu tembakau madura varietas Prancak-95 meningkat bila dosis pupuk N dan K ditingkatkan. Dosis pupuk NPK untuk tembakau madura Prancak-95 adalah 60 kg N + 45 kg P2O5 + 102 kg K2O + 5 ton pupuk kandang per hektar. Paket pupuk tersebut dapat menghasilkan tembakau rajangan kering 1.168 kg/ha dengan nilai indeks tanaman 110,1.Kata kunci: Nicotiana tabacum L., pupuk NPK, tembakau madura

Abstract

Tobacco Generally farmers in Lombok apply single fertilizer of ZA or Urea (as a source of N), and SP36 (as source of P), without combining with K and Mg fertilizers. The fertilizers are added more than twice with unappropriates doses. Application of compound fertilizer might increase growth, yield and quality of Virginia fc tobacco at Central Lombok, West Nusa Tenggara Province, because the fertilizer consists of NPK macro nutrients which have important role for tobacco. The experiment was carried out at Kopang Rembiga village, Kopang District in 2014. The objective to was identify the effect of NPKMg compound fertilizer on growth, yield and quality of Virginia tobacco. Split Plot Design with three replicates was used to arrange treatments. Three varieties of Virginia tobacco (Coker 176, Coker 319 and NC 297) were set as main plots, and three rates of NPKMg fertilizer (60, 80 and 100 kg N/ha) were arranged as sub plots. Results showed that increasing of NPKMg fertilizer up to 100 kg N/ha increased growth, yield and quality of three varieties of Virginia tobacco. Addition of 100 kg N/ha NPKMg (100 kg N+ 60 kg P2O5 + 133 kg K2O + 13.34 kg MgO per hectare) gave the highest values of grade index and crop index of three varieties, thus the fertilizer could be recommended for Virginia tobacco in Lombok.

Abstract

Sugarcane is proved to absorb more Si than any other nutrient from soil; therefore continuous cropping of the plant at the same soil would bring consequences of more Si and organic matter depletion. Silicon (Si) is considered a beneficial nutrient for sugarcane production. Field study was carried out in 2013-2014 at Kempleng village; Purwoasri sub district; Kediri district; East Java. The objective was to find out the effect of frequency and concentration of Si liquid fertilizer on Si and N absorptions, stem diameter and length, yield and commercial cane sugar (CCS) of sugarcane var PSBM 901. Split plot design with three replicates was employed to arrange the treatments. As main plots were frequency of spraying (one time, two times, three times, and four times with interval of 20 days started at 30 days after planting), while as sub plots were concentration of Si fertilizer (0, 15% Si, 30% Si). Results showed that interaction between frequency and concentration of Si affected on all parameters observed. Spraying of sugarcane four times with 30% Si gave highest value of cane yield, rendement, and sugar yield, i.e. 184.16 tons/ha and 8.36%, 15.37 ton/ha respectively.Keywords: sugarcane, yield, commercial cane sugar AbstrakTebu tergolong jenis tanaman akumulator unsur Si, sehingga penanaman secara terus menerus pada lahan yang sama akan berakibat semakin terkurasnya unsur Si dan menurunnya bahan organik dalam tanah. Unsur Si berperan penting terhadap pertumbuhan tebu terutama pada tanah-tanah tropis. Untuk mengetahui efektivitas pupuk Si cair pada tebu, telah dilakukan penelitian lapang pada tahun 2013-2014, yang berlokasi di Desa Kempleng, Kecamatan Purwoasri, Kabupaten Kediri, Jawa Timur. Tujuannya untuk mengetahui pengaruh frekuensi dan konsentrasi pemberian pupuk cair Si terhadap serapan Si dan N, pertumbuhan, produksi dan rendemen tebu varietas PSBM 901. Penelitian disusun dengan Rancangan Petak Terbagi dengan tiga ulangan. Sebagai petak utama adalah frekuensi penyemprotan (1 kali, 2 kali, 3 kali, 4 kali dengan interval 20 hari sekali sejak umur tebu 30 hari). Sebagai anak petak adalah konsentrasi pupuk Si (0, 15%, 30%). Hasil penelitian menunjukkan bahwa interaksi antara frekuensi penyemprotan dan konsentrasi pupuk Si berpengaruh terhadap peningkatan serapan Si dan N, diameter batang, panjang batang, produksi dan rendemen tebu. Penyemprotan pupuk Si pada tebu sebanyak 4 kali (umur 30, 50, 70 dan 90 hari) dengan konsentrasi 30% Si menghasilkan tebu dengan bobot dan rendemen tertinggi serta gula hablur, yaitu masing-masing sebesar 184,16 ton/ha dan 8,36% serta 15.37 ton/ha.Kata kunci: Tebu, Si, produksi, rendemen
