Abstract

Rice (Oryza sativa L.) is a major staple crop in Indonesia, but its productivity in acidic sulfate soils is limited by low nutrient availability and high soil acidity.  This study aimed to evaluate the effect of combination of NPK synthetic fertilizer+decanter solid and flooding level on the growth and yield components of rice in acidic sulfate soil.  The experiment was conducted in a greenhouse using a Completely Randomized Design with two factors and three replications. The first factor was fertilizer combination (F0: NPK 450 kg ha⁻¹; F1: NPK 300 kg ha⁻¹ + decanter solid 2 t ha⁻¹; F2: NPK 150 kg ha⁻¹ + decanter solid 4 t ha⁻¹; F3: decanter solid 6 t ha⁻¹), and the second factor was flooding level (W1:10 cm and W2: 0 cm/no flooding). The results showed that fertilizer combination had no significant effect on rice yield components and productivity, whereas flooding significantly increased grain number, panicle branches, 1000-grain weight, and productivity. These findings indicate that flooding management plays an important role in improving rice productivity in acidic sulfate soils.   Padi (Oryza sativa L.) merupakan komoditas pangan utama di Indonesia, namun produktivitasnya di tanah sulfat asam terbatas oleh ketersediaan nutrisi yang rendah dan keasaman tanah yang tinggi. Penelitian ini bertujuan untuk mengevaluasi pengaruh kombinasi pupuk sintetis NPK+decanter solid dan tinggi genangan air terhadap komponen hasil padi di tanah sulfat asam. Percobaan dilakukan di rumah kaca menggunakan Rancangan Acak Lengkap dengan dua faktor dan tiga ulangan. Faktor pertama adalah kombinasi pupuk (F0: NPK 450 kg ha⁻¹; F1: NPK 300 kg ha⁻¹ + decanter solid 2 t ha⁻¹; F2: NPK 150 kg ha⁻¹ + decanter solid 4 t ha⁻¹; F3:  decanter solid 6 t ha⁻¹), dan faktor kedua adalah tinggi genangan air (W1: 10 cm dan W2: 0 cm/macak-macak). Hasil penelitian menunjukkan bahwa kombinasi pupuk tidak memiliki pengaruh yang signifikan terhadap komponen hasil padi dan produktivitas, sedangkan genangan air secara signifikan meningkatkan jumlah butir padi, cabang malai, berat 1000 butir padi, dan produktivitas. Dengan demikian, pengelolaan genangan air memiliki peran penting dalam meningkatkan produktivitas padi di tanah asam sulfat.
