Growth and Yield Performance of Aromatic Fine Rice as Influenced by Varieties and Fertilizer Managements

Abstract

This Research was conducted to investigate the effect of fertilizer management on growth and yield performance of aromatic fine rice varieties. The experiment consisted of two factors were aromatic fine rice and fertilizer management. There were four varieties namely Kalizira, Kataribhog, Tulshimala and BRRI Dhan34 with four fertilizer treatments recommended dose of fertilizers (T1), cowdung @ 10 tha-1 (T2), 50% of recommended dose of fertilizers + 50% cowdung(T3), 75% of recommended dose of fertilizers + 50% cowdung (T4). The result showed that BRRI Dhan 34 significantly superior for effective tillers number/ hill (18.46), panicles length (26.67cm), grains number/ panicle (146.30), harvest index (40.73 %), grain protein content (6.23%), grain yield (2.79 tha-1), straw yield (4.06 tha-1), and biological yield (6.85 tha-1). Among fertilizer management, the highest effective tillers number/hill (16.20), grains number/ panicle (142.45, panicles length (26.66 cm),1000 grain weight (13.75), grain protein content (10.2%), biological yield (6.30), were obtained from T3 treatment. Based on interaction effect showed that the highest effective tillers number/hill (18.36), grains number/ panicle (155.33), panicles length (26.73 cm), grain protein content (10.80%), biological yield (7.85) was found with BRRI Dhan 34 combined with T3 treatment. However, grain yield increased with the increase in nitrogen levels. Together tillers number/hill, grains number/panicle, grain protein content, harvest index, grain yield was the main responsible yield contributing characters to improve the yield quality of aromatic fine rice.

Integrated nutrient management practices affect the growth performance of aromatic fine rice varieties in Boro season

“…The variation in plant height among the varieties was probably due to heredity or varietal characters. Similar results were reported elsewhere (Kirttania et al, 2013;Ray et al, 2015;Islam et al, 2021). Plant height was significantly influenced by nutrient management irrespective of growth stages.…”

Influence of seedling age and integrated nutrient management on growth and yield of aromatic rice (cv. BRRI dhan34)

“…However, considering nutrient management the highest 1000-grain weight (12.54 gm) was found with 75% of RDF + poultry manure @ 2.5 t ha -1 and the lowest 1000-grain weight (10.74 gm) was obtained from control treatment (Table 3). In a similar study, Teli et al (2018); Mahata et al (2019) and Islam et al (2021b) found that, various combinations of organic manures and inorganic fertilizers had a significant effect on the 1000-grain weight of rice. Considering the interaction between seedling age and nutrient management, results revealed that, the highest 1000-grain weight (13.76 gm) was recorded from 30 days old seedling along with 75% of RDF + poultry manure @ 2.5 t ha -1 and the lowest 1000-grain weight (10.26 gm) was obtained from 60 days old seedling along with no manures and fertilizers (Table 4).…”

“…Also, the highest harvest index (43.03%) was found in 75% of RDF + poultry manure @ 2.5 t ha -1 and the lowest harvest index (41.60%) was obtained from treatment 50% of RDF + Cow-dung @ 5 t ha -1 (Table 3). Teli et al (2018);and Islam et al (2021b) stated that, the harvest index is significantly influenced by nutrient management. Also, Roy et al (2017) showed that, harvest index was significantly influenced by fertilizer management.…”
