Comparative seed yields of lowland rice (Oryza sativa L.): evaluating seeds sources and fertilizers

The use of high-quality seeds from high-yielding rice varieties (HYV) is crucial for enhancing grain yield.

Zusammenfassung:The use of high-quality seeds from high-yielding rice varieties (HYV) is crucial for enhancing grain yield. Yet, the supply of certified seed meets only 57.3% of the total rice seed demand, leading some farmers to plant non-certified local rice seeds. A study examining the effects of seed sources and fertilization on seed yields was conducted in Bogor Village, Sukra District, Indramayu Regency during the Dry Season of 2019. The treatments consisted of two factors: A. Seed sources (Local non-certified seed (Local-NC), HYV non-certified seed (HYV-NC), and HYV-certified seed) and B. Fertilization methods (Recommended Fertilizer (RF), RF+BioF, RF+P as top dressing, and RF+N as top dressing). These were designed in a Complete Block Design with three replications. Results showed that Local-NC was more susceptible to BPH and RSB than HYV varieties. Additionally, Local-NC had the highest percentage of off-type plants and produced the lowest grain and seed yields. The addition of P or N fertilizer to RF during the heading stage notably improved the panicle number per hill, 1000-grain, seed yields and rendement. Our findings suggest that optimal rice seed yields can be achieved by planting HYV– certified seeds and applying either RF + 18 kg P ha −1 or RF + 11.5 kg N ha −1 as top dressing.
