“…The highest straw yield was observed in Biroin with 3 kg ha -1 Zn application which was statistically similar with Gainja and the lowest straw yield (3.47 t ha -1 ) was observed in BRRI dhan57 without any Zn application (Table III). These results have conformity with the evidence of other study [33]. Higher levels of Zn (10 and 15 kg Zn ha -1 ) increased both straw and grain yields [34]- [37].…”

Zinc (Zn) deficiency is widespread nutrient disorder in lowland rice growing areas in Asia, especially in Bangladesh. Intensive cropping with modern varieties causes depletion of inherent nutrient reserves in soils. The application of Zn fertilizers results in higher crop productivity and increases Zn concentration in crops. A field experiment was conducted to evaluate the effect of Zn application on growth, yield, and grain-Zn concentration in eight varieties of rice. The experiment was laid out in a split plot design with a distribution of Zn rates (0 kg ha-1 and 3 kg ha-1 from ZnO) to the main plots and rice varieties (BRRI dhan49, BRRI dhan52, BRRI dhan56, BRRI dhan57, Kalizira, Biroin, Gainja and Khirshapath) to the sub-plots. Zinc application improved effective tillers hill-1, grains panicle-1 and 1000-grain weight which impacted the grain yield of rice. Among the eight rice varieties, a significant increase of grain yield was recorded in BRRI dhan49, BRRI dhan52, BRRI dhan56 and BRRI dhan57 due to application of Zn. Zinc concentration of grain significantly increased in all rice varieties except Biroin. The highest grain-Zn concentration (19.1 mg kg-1) was noted in BRRI dhan57 with 3 kg ha-1 Zn and the lowest value (11.3 mg kg-1) was observed in BRRI dhan52 without Zn application. The highest percent increase of grain Zn concentration over control was obtained in high yielding rice variety BRRI dhan49 and the lowest Zn concentration was found in local rice variety Biroin.

“…On the other hand, the minimum harvest index (41.93%) was found from the combination of BRRI hybrid Dhan2 along with the control (no zinc application) treatment combination. Similar findings were found in research of Zinzala and Narwade (2019).…”

“…Application of BRRI hybrid dhan5 along with 6 kg Zn ha -1 produced 48.13% higher grain yield over control treatment. The finding of the study was also in line with the findings of Islam et al (2021) and Zinzala and Narwade (2019).…”

Zinc deficiency in soil is currently a widespread problem in Bangladesh that significantly reduces the yield of a variety of crops, including rice. Despite the fact that many farmers started applying zinc fertilizer, many are unaware of the right amount and application technique. For this reason, to determine the impact of variety and zinc treatment on the performance of hybrid rice, a field experiment was carried out between November 2019 and May 2020 at the Sher-e-Bangla Agricultural University's experimental field in Sher-e-Bangla Nagar, Dhaka-1207. The experiment consisted of two factors as variety (3 types) viz., V1 – BRRI hybrid dhan2, V2 – BRRI hybrid dhan3 and V3 – BRRI hybrid dhan5 and, Zinc management (4 levels) viz., Zn0 – 0 kg ha-1 (control), Zn1 – 2 kg ha-1, Zn2 – 4 kg ha-1 and Zn3 – 6 kg ha-1. The experiment was laid out in a Randomized Complete Block Design (Factorial) with three replications. Data on different growth and yield parameter of rice were recorded and significant variation was found for different treatments. Regarding varietal performance, the maximum panicle number hill-1 (17.10), panicle length (28.03 cm), grain number panicle-1 (109.45), 1000-grain weight (26.50 g), grain yield ha-1 (6.94 t), straw yield ha-1 (8.58 t), biological yield ha-1 (15.51 t) and harvest index (44.62%) were found from the variety BRRI hybrid dhan5. Considering Zn effect, the maximum panicle number hill-1 (16.33), panicle length (27.14 cm), grain number panicle-1 (108.11), 1000-grain weight (25.38 g), grain yield ha-1 (6.81 t), straw yield ha-1 (8.34 t), biological yield ha-1 (15.15 t) and harvest index (44.88%) were found from 6 kg Zn ha-1. In the case of treatment combination of variety and zinc, the maximum panicle number hill-1 (20.17), panicle length (29.45 cm), number of grains panicle-1 (117.74), 1000-seed weight (27.43 g), grain yield (7.80 t ha-1), straw yield (9.20 t ha-1), biological yield (17.00 t ha-1) and harvest index (45.78%) were found from BRRI hybrid dhan5 along with 6 kg Zn ha-1. Therefore, the hybrid rice variety BRRI hybrid dhan5 with a Zn application of 6 kg ha-1 yielded considerably more grain than the other treatment combinations under evaluation.
