Abstract: |
Rice production would be major concem in recent years due to changing climatic conditions. With the objective of identifying best seeding date with best variety and plant geometry for rice cultivation in Mid Westem Hill, Nepal to address climate change, an experiment was conducted in two years (20 11-20 12) at Agriculture Research Station, Dailekh. Three rice varieties namely Khumal-1 0, NR-1 0585-B-B-4-3-2 and NR-1 0591-B-B-4-3-3 were seeded in four dates from May-27 to Jully-11 in fifteen days interval and then transplanted 25 days old seedlings from June-24 to August-7 with three plant geometries of 20cmx l5cm, 20cmx20cm and 20cm><25cm. The design was split split-plot design with three replications. The results showed that interaction effect of date of seeding, variety and plant geometry on grain yield of rice highly significant. NR-10585-B-B-4-3-2 (8.8 t ha- 1 ) and Khumal-10 (7.5 t ha- 1 ) produced highest yield when seeded on May-27 and then after yield significantly reduced. The seeding date was highly significant for grain yield (7.8 t ha- 1 - 1.6 t ha- 1 ) . The interaction effect of date of seeding and plant geometry was observed highly significant for grain yield where the plant geometry 20cmx 15cm produced highest grain yield (8.0 t ha- 1 ) when seeded on May-27 and transplanted on Jw1e-24. It can be concluded that the rice variety NR-1 0585-B-B-4-3-2 produced highest grain yield (8.9 t ha- 1 ) when seeded on May-27 and transplanted on Jtme-24 with plant geometry of20cmx2Qcm in Mid Western Hill, Nepal. |
