Peningkatan Pertumbuhan dan Hasil Padi Sawah Organik dengan Berbagai Macam Aplikasi Pupuk Hijau Glirisidia

Abstract

The object of the study was to obtain the types of application of Glirisidia green manures on the growth and yield of organic rice lowland. The experimental pot experiment was carried out in a randomized block design consisting of one factor and three replications. The treatment factor was 10 various application of Glirisidia leaves. The treatments are: 100% fresh Glirisidia leaves + 0% compost; 60% fresh Glirisidia leaves + 40% compost; 40% fresh Glirisidia leaves + 60% compost; 100% wind-dried Glirisidia leaves + 0% compost; 60% of wind-dried Glirisidia leaves + 40% compost; 40% wind-dried Glirisidia leaves + 60% compost; 100% sun-dried Glirisidia leaves + 0% compost; 60% of the sun-dried Glirisidia leaves + 40% of compost; 40% of the sun-dried Glirisidia leaves + 60% compost; and 0% Glirisidia leaves + 100% compost. The results showed that the various application of Glirisidia leaves increased the grain yield 34, 09% compared to the application of 0% Glirisidia leaf + 100% compost. The grain/ hill of yield could be improved by application of 100% fresh Glirisidia leaves + 0% compost (164,47 g grain/hill), 100% of wind-dried Gliricidia leaves (165,55 g grain/ hill) + 0% compost, or 100% sun-dried Gliricidia leaves + 0% compost (169,14 g grain/ hill). Keywords—: organic rice lowland; green manure; various application of Glirisidia leaves.

Respon Pertumbuhan dan Hasil Padi Sawah Organik Terhadap Residu Berbagai Macam Aplikasi Pupuk Hijau Glirisidia

“…Pupuk hijau legum tahunan merupakan salah satu pupuk organik yang berpotensi sebagai sumber bahan organik tanah dan unsur hara tanaman padi sawah N. Salah satu jenis pupuk hijau legum tahunan dari jenis Glirisidia memiliki kadar N tinggi dan dekomposisnya cukup cepat. Kandungan kadar N daun Glirisidia segar adalah N 4,14%, daun Glirisidia kering angin 3,13%, daun Glirisidia kering matahari 3,34% dan kompos pupuk kandang sapi memiliki kadar N 1,49% (Winarni, 2016;Winarni, 2018). Nitrogen adalah suatu unsur nutrisi merupakan komponen asam amino, protein, asam nukleat, klorofil, enzim, hormon dan beberapa metabolit esensial lain (Wijaya, 2010;Lakitan, 2012;Sugito, 2012).…”

“…Penelitian yang telah dilakukan oleh Winarni et al (2016) menunjukkan bahwa daun Glirisidia dengan dosis 20 t/ha meningkatkan karakter fisiologis, pertumbuhan tanaman dan hasil panen gabah. Hasil penelitian Winarni (2018) menunjukkan bahwa tidak ada perbedaan pengaruh aplikasi daun Glirisidia dalam bentuk segar, kering angin dan Glirisidia kering matahari. Aplikasi daun Glirisidia dalam bentuk segar 100% + kompos 0%, daun Glirisidia kering angin 100% + kompos 0% dan daun Glirisidia kering matahari 100% + kompos 0% mampu memberikan pertumbuhan tanaman dan hasil panen gabah yang tinggi.…”
