Improved early season management of sub1 rice varieties enhances post-submergence recovery and yield por Banayo, Niño P. M., Mabesa-Telosa, Ranee C., Singh, Sudhanshu, Kato, Yoichiro

“…Integrated management practice (IMP) consisting of: (i) application of fertilizer (compared with no fertilizer use in conventional practice), (ii) use of lower seeding rate (400 vs. 800 kg ha−1) in the nursery bed, (iii) use of slightly older seedling for transplanting (30 vs. 18 day-old), and (iv) higher planting density (33.3 vs. 25.0 hills m−2) gave yields higher by 8–87% compared with the conventional practice (1.3–2.4 t ha−1) in both seasons. …”
