Tarigan, Fathir Muhammad (2018) Respons Dua Tipe Buncis (Phaseolus Vulgaris L.) Terhadap Berbagai Aplikasi Dosis Pupuk Urea. Sarjana thesis, Universitas Brawijaya.
Abstract
Tanaman buncis (Phaseolus vulgaris L.) adalah tanaman sayuran semusim berpolong yang digolongkan dalam famili Leguminoceae merupakan salah satu komoditas penting di dunia. Terdapat dua jenis buncis berdasarkan tipe pertumbuhan dan kebiasaan panennya, yaitu buncis tipe tegak dan tipe rambat (Rubatzky dan Yamaguchi, 1998). Tingginya minat konsumsi masyarakat terhadap buncis tidak diimbangi dengan produksi tanaman buncis. FAO menjelaskan bahwa produksi buncis mengalami penurunan, sehingga permintaan buncis tidak dapat dipenuhi secara maksimal (Porch et al., 2013). Berdasarkan Basis Data Kementerian Pertanian (2015) menjelaskan bahwa produksi tanaman buncis cenderung mengalami penurunan berturut-turut setiap tahunnnya selama tahun 2010-2014. Kesuburan tanah yang rendah merupakan salah satu faktor yang mempengaruhi produksi tanaman buncis (Abebe, 2009). Penelitian dilaksanakan dengan menggunakan Rancangan Acak Kelompok Faktorial (RAKF) dengan 2 faktor. Sehingga, didapatkan 8 kombinasi perlakuan, yaitu 1) Tegak + Pupuk Urea 0 kg N.ha-1 (B1P0); 2) Rambat + Pupuk Urea 0 kg N.ha-1 (B2P0); 3) Tegak + Pupuk Urea 50 kg N.ha-1 (B1P1); 4) Rambat + Pupuk Urea 50 kg N.ha-1 (B2P1); 5) Tegak + Pupuk Urea 100 kg N.ha-1 (B1P2); 6) Rambat + Pupuk Urea 100 kg N.ha-1 (B2P2); 7) Tegak + Pupuk Urea 150 kg N.ha-1 (B1P3); 8) Rambat + Pupuk Urea 150 kg N.ha-1 (B2P3). Hasil penelitian menunjukkan bahwa terjadi interaksi antara tipe pertumbuhan dan dosis pupuk urea. Penambahan dosis 150 kg N.ha-1 memberikan peningkatan pertumbuhan dan hasil pada tipe tegak. Sedangkan, tipe rambat dengan dosis optimum 89,8 kg N.ha-1 mampu memberikan hasil optimal daripada perlakuan lainnya. Tipe rambat memiliki rata-rata pertumbuhan dan hasil lebih tinggi dibandingkan dengan tipe tegak.
English Abstract
Beans (red: pole bean or bush bean) (Phaseolus vulgaris L.) are plants classified in the Leguminoceae family as one of the paramount commodities in the world. There are two types of beans based on the type of growth and harvesting habits, namely erect type bean and vine type (Rubatzky and Yamaguchi, 1998). The high interest of public consumption on beans is not balanced with bean plant production. FAO explained that the production of beans has decreased, so the demand for beans can not be met optimally (Porch et al., 2013). Database of the Ministry of Agriculture (2015) explains that bean production tends to decrease successively every year during 2010-2014. In 2010 to 2012 national beans production reached 336.494 tons, 334.659 tons and 322.097 tons. However, in 2013 increased production to 327.378 tons and decreased again in 2014 to 318.214 tons. Low soil fertility is one of the factors that affect the production of green beans (Abebe, 2009). The research was conducted by using Randomized Complete Block Design (RCBD) with 2 factors. So, got 8 treatment combination, those are 1) Erect + Urea 0 kg N.ha-1 (B1P0); 2) Vine + Urea 0 kg N.ha-1 (B2P0); 3) Erect + Urea 50 kg N.ha-1 (B1P1) 4) Vine + Urea 50 kg N.ha-1 (B2P1); 5) Erect + Urea 100 kg N.ha-1 (B1P2); 6) Vine + Urea 100 kg N.ha-1 (B2P2); 7) Erect + Urea 150 kg N.ha-1 (B1P3); 8) Vine + Urea 150 kg N.ha-1 (B2P3). The results showed that there was an interaction between the growth type and the dose of urea fertilizer. The addition dose of 150 kg N.ha-1 provides increasing to growth and yield on the erect type. Meanwhile, the optimum dose of 89,8 kg N.ha-1 was able to give the optimize results than other treatments on the vine type. The vine type has an average higher of growth and yield than the erect type.
