Abstract
This research was aims to examine the effectiveness of application of liquid organic fertilizer Azzolla Microphylla and organic fertilizer takakura on the growth and yield of mustard greens (Brassica juncea. Azzola as a green manure can improve the chemical properties of the soil because it can meet the nitrogen needs of plants . Giving nitrogen to plants can accelerate plant growth , especially stems and leaves . The N content of Azolla liquid fertilizer can stimulate plant growth . Giving Azolla microphylls as a liquid organic fertilizer is more easily absorbed by plants so that plant growth can be optimal . In this study , observing the effect of applying liquid organic fertilizer Azolla microphylls on sweet mustard greens using Takakura organic compost media at the age of 21 , 28 , and 39 DAP with the observed variables being the number of leaves , leaf length and width and the variables observed after harvest . including weight of consumption and volume of roots . The results of this study showed that there was no significant effect of / on the application of liquid zols fertilizer and Takakura fertilizer on the number of leaves , length and width of the mustard greens (Brassica juncea ) at 21 , 28 , and 39 days after planting (HST ) between zols liquid fertilizer and Takakura fertilizer . The application of Azolla fertilizer and Takakura growing media had a significant effect on the consumption weight of mustard (Brassica juncea ) plants . It can be seen that the consumption weights of T3 , T3 , T1 and T4 have a high value compared to T0 or without fertilizer application .
Highlights
Tanaman sawi (Brassica juncea) merupakan jenis sayuran yang banyak digemari oleh masyarakat karena memiliki rasa yang segar serta mengandung vitamin A, B, dan sedikit vitamin C (Hendro, 2004) Tanaman sawi dapat dibudidayakan di dataran rendah maupun dataran tinggi (5-1.200 m) di atas permukaan laut, sehingga jenis tanaman ini dapat tumbuh di tempat yang berudara panas maupun berudara dingin
The results of this study showed that there was no significant effect of / on the application of liquid zols fertilizer and Takakura fertilizer on the number of leaves, length and width of the mustard greens (Brassica juncea ) at 21, 28, and 39 days after planting (HST ) between zols liquid fertilizer and Takakura fertilizer
Pengaruh Pemupukan Organik Takakura dengan Penambahan EM4 terhadap Pertumbuhan dan Produksi Tanaman Kacang Hijau (Phaseolus radiatus L.)
Summary
Pupuk organik Takakura merupakan pupuk yang terbuat dari sampah rumah tangga yang berupa sisa-sisa makanan melalui proses pengomposan dan mengandung unsur hara makro, mikro lengkap, sehingga dapat menyuburkan tanah dan tanaman budidaya. Contohnya tanaman paku air Azolla (Simanungkalit, Suriadikarta, Saraswati, Setyorini, & Hartatik, 2006) Penelitian yang dilakukan oleh (Amini, Dwirayani, & Eviyati, 2021) pemupukan dengan takakura terdapat interaksi dengan pertumbuhan tanaman sayuran. Peneliti juga memberikan perlakuan dengan penambahan pupuk organik cair dari pupuk hijau Azolla Micropylla. Pupuk organik cair Azolla merupakan jenis pupuk yang dapat digunakan untuk meningkatkan produktivitas tanaman. Azolla sering ditemukan di sawah yang tergenangi air dan salah satu sumber N alternatif bagi tanaman. Azolla merupakan tanaman jenis paku air yang hidupnya bersimbiosis dengan. Nitrogen bebas yang diikat dari udara akan diubah menjadi bentuk yang tersedia bagi tumbuhan. (Sudjana, 2014)
