Ammonia Volatilization from Urea-Application Influenced Germination and Early Seedling Growth of Dry Direct-Seeded Rice
Seed germination percentage of Apo (a) and Hanyou3 (b) under application of AS50 (ammonium sulfate, 50 kg N ha−1), AS100 (ammonium sulfate, 100 kg N ha−1), U50 (urea, 50 kg N ha−1), U100 (urea, 100 kg N ha−1), U50 + NBPT1 (50 kg N ha−1 + 1.09 kg NBPT ha−1), and U100 + NBPT2 (100 kg N ha−1 + 2.18 kg NBPT ha−1) in comparison with zero N input (control) in a field experiment. Error bars represent the standard error.
