Peranan Amelioran Pupuk Organik terhadap Hasil Padi pada Musim Tanam Kedua di Lahan Kering Ngawen Gunungkidul Daerah Istimewa Yogyakarta

Abstract

<em>Rice</em><em> </em><em>cultivation</em><em> in the second growing season in dry land at Gunungkidul Special Region of Yogyakarta requires additional irrigation and improvement of physical, chemical and biological soil properties. This study aimed to determine the role of organic fertilizer ameliorant on rice yields during second growing season in dry land. The research was conducted in Sambirejo Watusigar Ngawen Gunungkidul Special Region of Yogyakarta during second growing season from March to July 2019. The study used a Randomized Completely Block Design (RCBD) with 3 treatments in the form of no ameliorant, ameliorant of 2 tons ha<sup>-1</sup> and ameliorant 4 tons ha<sup>-1</sup>, with 5 replications. The results showed that the use of ameliorant 2 tons ha<sup>-1</sup> produced rice 5.64 ton ha<sup>-1</sup> and ameliorant 4 tons ha<sup>-1</sup> produced rice 6.04 ton ha<sup>-1</sup>, which was significantly higher than without ameliorant which only produced 5.29 ton ha<sup>-1</sup> of rice.</em>

Analysis of soil fertility status on rice (Oryza sativa L.) planted land in Polewali District, Polewali Mandar Regency

“…Recommended soil fertility improvement efforts include the use of organic matter. The addition of organic matter that contains a lot of P and K elements such as chicken manure, goat or cow manure can increase the availability of P in the soil because organic acids resulting from the decomposition of organic matter have the ability to bind cations such as Al and Fe through chelation bonds so that phosphorus (P) can be available (Anshori et al, 2021). The selection of organic fertilizers is highly recommended to maintain nutrient stability, prevent nutrient imbalances due to excess chemical fertilizers, and create sustainable agriculture.…”

The Strategy of Soybean Development on Dryland Agroecosystem in Gunungkidul Regency, D.I. Yogyakarta, Indonesia

“…Apart from the water factor, according to Maro'ah et al ( 2021) soil fertility factors must be a concern. Soil fertility can be maintained or increased by applying organic fertilizer ameliorant at the dose of 2 to 4 ton ha -1 (Anshori et al, 2021c).…”

Status Kesuburan Tanah sebagai Dasar Strategi Pengelolaan Lahan Sawah di Kabupaten Bantul, Indonesia

“…Selain itu, peningkatan kesuburan juga dapat dilakukan dengan penggunaan pupuk organik sebelum penanaman seperti pupuk kandang. Hasil penelitian Anshori et al (2021) hasil produksi gabah padi, serta keuntungan penjualan beras petani di daerah Bantul semakin meningkat setelah dilakukan pengelolaan aplikasi pupuk organik pada tanah sawah saat lahan kering. Pemilihan pupuk organik sangat dianjurkan untuk menjaga kestabilan hara, mencegah ketimpangan hara akibat pupuk kimia berlebih, serta menciptakan pertanian lestari dan berkelanjutan.…”
