Sekarang ini, isu kelangkaan air, harga pupuk yang tinggi, dan dampak negatif dari penggunaan bahan kimia yang tinggi pada bidang pertanian sedang berkembang, sehingga memerlukan peningkatkan efisiensi pada budidaya padi. Berdasarkan beberapa penelitian, SRI merupakan pendekatan yang menjanjikan. Pot percobaan dilakukan dengan kerangka kerja SRI dengan variasi irigasi tergenang (CF), sedikit air (SWD), dan kapasitas lapang (FC); diinteraksikan dengan empat dosis pemupukan organik yang berbeda (F 100, F 50, F 0, dan LF). Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pengelolaan air dan pupuk organik terhadap pertumbuhan dan perkembangan padi. Hasil penelitian menunjukkan bahwa Eh tanah berbeda nyata di antara tiga pengelolaan air (p<0.05) dimana FC memiliki nilai tertinggi diikuti oleh SWD dan CF. Pemupukan organik tidak berpengaruh nyata terhadap Eh tanah. Jumlah anakan pada SWD berbeda nyata dengan CF dan FC (p<0.05). Di sisi lain, pengelolaan air dan pupuk organik tidak berbeda nyata terhadap tinggi tanaman. SWD secara signifikan meningkatkan biomassa dan produksi. Pupuk organik secara nyata menurunkan jumlah anakan, biomassa, dan produksi padi. Sebagai kesimpulan, SWD memberikan kondisi lingkungan tumbuh yang lebih baik untuk pertumbuhan padi dan meningkatkan kinerja tanaman padi, sedangkan pengaruh pupuk organik tidak dapat dibedakan.
