| Judul Artikel | TANGGAP MORFOLOGIS GALUR PADI GOGO TERHADAP KEKERINGAN DAN DEFISIENSI HARA |
| Abstrak (Bhs. Indonesia) | Abstrak Penelitian ini bertujuan untuk: 1) Mengkaji pengaruh cekaman kekeringan terhadap pertumbuhan galur-galur padi gogo, 2) Mengkaji respon galur-galur padi gogo terhadap defisiensi hara 3) Mendapatkan galur padi gogo yang toleran terhadap cekaman kekeringan dan efisien hara. Penelitian telah dilaksanakan menggunakan media kultur hara di screen house Fakultas Pertanian UNSOED. Rancangan yang digunakan adalah Split plot design. Faktor pertama terdiri empat taraf yaitu K0H1 (Tanpa Cekaman kekeringan 0 % PEG dan cukup hara) K0H2 (Tanpa cekaman kekeringan 0 % PEG dan kekurangan hara), K1H1(Cekaman kekeringan 10 % PEG dan cukup hara), dan K1H2 (Cekaman kekeringan 10 % PEG dan kekurangan hara). Faktor kedua yaitu 20 genotip padi gogo hasil persilangan dan 2 varietas padi yaitu koshimura dan IR-64.Variabel yang diamati yaitu tinggi tanaman, panjang akar, jumlah daun, bobot akar basah, bobot akar kering, bobot tajuk basah, bobot tajuk kering, indeks toleransi dan nilai efisiensi hara. Hasilpenelitianmenunjukkanbahwa 1) cekaman kekeringan PEG 10 % ( meningkatkan panjan gakar sebagai upaya adaptasi tanaman terhadap kondisi stres kekeringan, 2) Cekaman hara menurunkan tinggi tanaman, bobot tajuk basah dan bobot tajuk kering, tetapi menaikkan panjang akar tanaman 3) Galur padi gogo yang berpotensi toleran kekeringan dan efisien hara yaitu SET 2. KM.12.6, SET 3.PM.23.11, SET 2. MK. 25.5, SET 1. 23, SET 3. MK. 24.3, SET 1. 24, SET 1. 22, SM. 37. 1, dan SET 3. SF. 11. |
| Abtrak (Bhs. Inggris) | Abstract This research aims to: 1) Assessing the impact of drought stress on the growth of upland rice strains, 2) Assessing the response of upland rice strains to nutrient deficiency 3) Acquire tolerant upland rice lines to drought stress and nutrients efficient. Research had been conducted using nutrient culture medium in the screen house of UNSOED’s Faculty of Agriculture. Split plot design was used on this research. The first factor was consisted by four levels;K0H1 (Without drought stress and sufficient nutrients), K0H2 (Without drought stress and nutrient deficiencies), K1H1 (10% PEG drought stress and sufficient nutrients), and K1H2 (10% PEG drought stress and nutrient deficiencies). The second factors were 20 genotypes of upland rice (G) from cross-breeding and two varieties of rice which were Koshimura and IR-64. The observed variables were plant height, root length, sum of leaves, roots wet weight, root dry weight,canopywet weight, canopy dryweight, index tolerance and nutrient efficiency. The results showed that 1) drought (PEG 10%) increased root length as plant adaptation to drought stress, 2) Stress nutrient decreased plant height, canopy wet weight and canopy dry weight, but increase theplantroot length 3) the upland rice strains tolerant todrought and nutrients efficientwere SET 2. KM.12.6, SET 3.PM.23.11, SET 2. MK. 25.5, SET 1. 23, SET 3. MK. 24.3, SET 1. 24, SET 1. 22, SM. 37. 1, dan SET 3. SF. 11. |
