Description Rice cultivation with a ratoon system is one of the efforts to increase rice production in tidal land. This study aims to determine the effect of harvest time and nitrogen fertilization of the main plant on the growth and yield of ratoon rice in tidal swampland. This study was conducted in the Experimental Field of Banyuasin District Agriculture Office in Tanjung Lago Regency. The design used in this study was the Split Plot Design which was repeated three times. The Main Plots: Fertilization N (N) consists of N1;½ dose at planting + ½ dose of primordia phase, N2; 1/3 dose at planting + 1/3 dose at primordial phase + 1/3 dose at harvest, and N3; 1/3 dose at planting + 1/3 dose at primordia phase+ 1/6 dose at harvest +1/6 dose at 21 days after harvest.Plot: Harvest time (W) consists of W1; the main crop is harvested 5 days before 100% ripening, W2; main crop is harvested when 100% ripening, and W3; the main crop is harvested 5 days after 100% ripening. The results showed that the harvest time and N fertilizer of the main plants affected the growth and yield of ratoon rice in tidal land. Treatment of harvest time 5 days before 100% ripening and N fertilization has given 1/3 dose at planting + 1/3 dose of primordia phase +1/3 dose at harvest, tended to show higher growth and yields of ratoon rice than other treatments, that is 2.06 tons/ha or 54.2 percent compared to the main crop.
Budidaya tanaman padi dengan sistem ratun merupakan salah satu upaya peningkatan produksi padi di Lahan pasang surut.  Penelitian bertujuan untuk mengetahui pengaruh waktu panen dan pemupukan Nitrogen  tanaman utama terhadap pertumbuhan dan hasil ratun padi di Lahan pasang surut.  Penelitian dilaksanakan pada bulan April – Agustus 2019 di Lahan Percobaan Dinas Pertanian Kabupaten Banyuasin di Desa Seri Menanti Kecamatan Tanjung Lago, yang terletak pada -203’45, 972”S 104045’36,054”E.  Rancangan yang digunakan dalam penelitian ini adalah Rancangan Petak Terbagi (Split Plot Design) yang diulang sebanyak tiga kali.  Adapun Petak Utama: Pemupukan N (N)  terdiri dari N1;  ½ dosis saat tanam + ½ dosis fase primordia, N2;1/3 dosis saat tanam + 1/3 dosis fase primordia + 1/3 dosis saat panen, dan N3;  1/3 dosis saat tanam + 1/3 dosis fase primordia + 1/6 dosis saat panen + 1/6 dosis pada  21 hari setelah panen.  Anak Petak : Waktu panen (W) terdiri dari W1; tanaman utama dipanen 5 hari sebelum 100% masak, W2; tanaman utama dipanen saat 100% masak dan W3; tanaman utama dipanen 5 hari setelah 100% masak.  Hasil penelitian menunjukan,  waktu panen dan pemupukan N tanaman utama berpengaruh terhadap pertumbuhan dan hasil ratun padi di Lahan pasang surut.  Perlakuan waktu panen 5 hari sebelum 100% masak dan pemupukan N yang diberikan 1/3 dosis saat tanam + 1/3 dosis fase primordia + 1/3 dosis saat panen (W1N2), cenderung menunjukkan hasil ratun padi lebih tinggi dibanding perlakuan lainnya, yaitu sebesar 2.06 ton ha-1 atau 54.2 persen  dibanding hasil tanaman utama.
