“…Shorter plants at the conventional system of planting than other treatment levels at three initial growth stages could be attributed to the late transplanting of the crop (30 DAS), which in turn led to slower growth. Seedlings transplanted at a young age (<15 days) under SRI had a more significant time to acclimatize to field conditions which consequently resulted in increased plant height (Kesh et al, 2017). Non-significant plant height at maturity stage indicated that being a genetically made characteristic of the individual rice variety, it would not vary with the change of spacing and fertilizer levels at the end of its life cycle.…”

A field experiment was conducted during the late Samba (September-January) season of 2018-19 to evaluate the growth, root characters, and yield of rice due to high-density planting. The soil of the experimental field was clay loam in texture with a neutral reaction. The experiment consisted of eight treatments with different spacing and fertilizer levels such as T 1-25cm x 25cm with 100% Recommended Dose of Fertilizers (RDF), T 2-25cm x 20cm with 100% RDF, T 3-25cm x 15cm with 100% RDF, T 4-25cm x 15cm with 125% RDF, T 5-20cm x 20cm with 100% RDF, T 6-20cm x 15cm with 100% RDF, T 7-20cm x 15cm with 125% RDF and T 8-Conventional cultivation (20cm x 10cm with 100% RDF) and replicated thrice. The results revealed that significantly taller plants were recorded with all SRI treatments (T 1 to T 7) compared to conventional planting in all the stages except at maturity, which resulted in non-significant results. A reverse trend was noted with leaf area index and straw yield. Root length and root volume of rice were higher in wider planted treatments (T 1 , T 2 , and T 5) than other closer spaced treatments with the least in T 8. Treatments T 5 , T 4 and T 3 produced significantly higher grain yield over other treatments with the minimum in T 8. The results inferred that too wider and too closer spacing levels under the SRI method would lead to a reduction in yield though other growth parameters were recorded more.
